- QUESTIONS AND ANSWERS
-
- 1. Information about this document
-
- [1.1] Welcome
-
- Welcome to "The Rose FAQ", a collection of six informative articles about
- roses. These articles are primarily available on the World Wide Web at
- http://www.mc.edu/~nettles/rofaq/rofaq-top.html . The FAQ is sometimes
- posted to the newsgroup rec.gardens.roses. This first article discusses
- Frequently Asked Questions (FAQ) in the Usenet newsgroup rec.gardens.roses.
- If you are new to the newsgroup rec.gardens.roses, you might want to read
- this article before posting questions to the newsgroup. There are additional
- FAQ articles (posted separately) which discuss Old Roses, Modern Roses,
- English Roses, and mail-order suppliers of roses.
-
- Note that many things related to growing roses well depend upon your local
- climate. Contact your local rose society or nursery to find out how to grow
- roses in your area.
-
- [1.2] What's New with the FAQ
-
- Most of you already know about it, but the American Rose Society has an
- excellent World Wide Web site at http://www.ars.org . The FAQ has received
- only minor changes during the last few months.

-
- 2. Rose Care
-
- [2.1] Why won't my rose bloom?
-
- Here are some of the reasons that roses don't bloom.
-
- 1. The rose plant is not getting enough sun. Roses need at least 6 hours
- of direct sun a day to perform well.
- 2. The rose needs more water. Roses like at least an inch of water per
- week during the growing season.
- 3. The plant has been given too much fertilizer, especially Nitrogen. Too
- much fertilizer can either damage the plant or cause it to grow extra
- leaves and stems at the expense of blooms.
- 4. The rose is a new plant. Don't expect too much from a plant during its
- first year.
- 5. Rose is a once blooming variety. This means it will bloom only once a
- year in the late spring or early summer.
- 6. Soil pH is too low or too high. If the pH is not in the range of 6.0 to
- 6.8 (ideally 6.5) then nutrient uptake will be reduced, and the plant
- won't be getting the food it needs to produce flowers.
- 7. Not enough foliage. If the bush doesn't have adequate foliage, it can't
- produce the food it needs to make new flowers. Inadequate foliage may
- result from disease or too little fertilizer.
-
- [2.2] How much sun do roses need?
-
- Roses prefer a full day of sun. Give roses at least 6 hours of direct sun a
- day. Morning sun is especially important because it dries the leaves which
- helps prevent disease.
-
- Most roses do poorly in shade. Plants bloom less, are leggy, and are more
- likely to get diseases.
-
- [2.3] Which roses can be grown in shade?
-
- Many Hybrid Musks and some Albas can tolerate partial shade. A few other
- varieties including the Floribunda "Gruss An Aachen" can be planted in
- partial shade.
-
- Some other roses that may grow in partial shade are the Rugosas,
- Iceberg(FB), Zephirine Drouhin (Bourbon), Souvenir du Docteur Jamain(HP) and
- Madame Plantier.
-
- [2.4] How much water do roses need?
-
- Roses appreciate lots of water. Water generously, at least 1 inch/week,
- preferably 2 inches/week during growing season. Water every 4-7 days during
- the summer when needed. Each bush needs about 4-5 gallons/week during the
- hot summer.
-
- Roses get all their food either through their leaves (foliar feeding) or
- through their roots. The only medium for transporting food is water.
-
- Infrequent deep watering is preferred to frequent light watering to help
- promote a deep root system. Deep root systems help the rose to survive both
- droughts, and winter freezes. Frequent, light watering causes roots to form
- very near the soil surface, making the plant more susceptible to summer
- 'baking' and winter freezes.
-
- Try to avoid getting the leaves wet (which promotes disease) when watering
- late in the day. However, on hot days wetting the foliage can reduce
- transpiration and relieves heat stress.
-
- [2.5] How do I deadhead roses?
-
- Deadheading is cutting off flowers as they wither or don't look as good. Old
- blooms left on the plant may have been pollinated and may begin to form seed
- pods (hips). The formation of hips requires a lot of energy from the plant
- and slows flower production. By preventing the formation of hips,
- deadheading encourages the rose bush to grow new flowers.
-
- The choice of which spot to deadhead at is influenced by what shape you want
- the bush to take, and which direction you want a particular cane to grow.
- Usually, you will want to cut the stem at a 45-degree angle just above an
- outward-facing leaf. Make sure the high side of the cut is the side the leaf
- set is on.
-
- To deadhead, remove the flower by making a diagonal cut just above the next
- 5 or 7-leaf branch down on the stem. The idea is to cut to a bud eye capable
- of producing a healthy cane. If this would cause too much of the cane to be
- removed, a 3-leaf branch can be chosen instead. The first year cut back to
- the first 3 or 5-leaf branch. In following years cut far enough down to get
- to a 5-leaf branch with a leaf bud that is facing outward. This will open up
- the plant.
-
- Once blooming roses do not need to be deadheaded. They bloom once and then
- they are finished blooming for the year. However, once-blooming roses may be
- (in fact, should be) pruned after they are finished blooming. They should
- NOT be pruned in the fall or before they bloom because they bloom on the
- previous year's growth.
-
- Stop deadheading as of September 1 in zones 4 and 5. It is a good practice
- to let the last roses on HT's produce hips because it makes them more frost
- hardy. It causes the plant to undergo chemical changes that slow down
- growth, inhibit blooming and generally prepare for dormancy by focusing its
- energy on 'hardening' the canes. The formation of hips tells the plant that
- it's "done its job" and can now rest from its labors.
-
- [2.6] How do I prune roses?
-
- There are three main purposes to be accomplished when pruning roses.
-
- * Keep the plant healthy.
- * Encourage the plant to grow in a desired shape.
- * Encourage blooming, either more blooms or larger blooms.
-
- The proper tool for most pruning is a sharp clean set of bypass pruners.
- Anvil pruners should not be used for roses as they crush the stem being cut.
- A saw or lopping shears may be used to cut very large canes (1/2 inch
- diameter or greater) All pruning cuts on canes greater than 1/4 inch
- diameter should be sealed with nail polish or glue to prevent cane borers
- from entering.
-
- Proper pruning will help keep a rose bush healthy. Dead and diseased wood
- should be removed as soon as possible to prevent further damage to the bush.
-
- The future shape of the bush can be influenced by the location of each
- pruning cut. Opening up the bush to increase air circulation will help
- prevent diseases. Since rose bushes like to send out a strong lateral cane
- at the node just below a pruning cut, try to make pruning cuts about 1/4
- inch above an "outward" facing leaf bud. By doing this and removing plant
- material from the center of the bush you will create a more open vase-shaped
- plant less susceptible to disease. Whenever two canes cross each other, one
- can be removed.
-
- Roses can be encouraged to bloom better if thin, weak and non-productive
- wood is removed to allow the plant to concentrate its blooming on the larger
- healthier canes. Generally with Hybrid Teas any cane thinner than a pencil
- should be removed. Plants may be pruned hard to encourage larger blooms but
- fewer blooms (commonly done with Hybrid Teas.) Or the plant may be pruned
- lightly and allowed to grow larger and produce more flowers that are smaller
- (commonly done with some shrub roses.) Prune first year plants only lightly
- to allow them to concentrate on establishing a strong root system.
-
- [2.7] How do I protect my rose bushes during the winter?
-
- Local advice is preferred for this question, but here are some general
- guidelines for winter care of rose bushes for those living in colder
- climates. The major dangers to the plant in winter are the drying of the
- wind, the effect of alternate thawing and freezing cycles on the plant when
- winter temperatures fluctuate, the inability of the plant to take in water
- if the soil is frozen, and damage from the cold itself to the canes and bud
- union.
-
- 1. If you live in an area with harsh winters, plant cold-hardy roses. Your
- choices are more restricted that way, but you will save yourself a lot
- of work and heartbreak. Many once blooming old roses are very
- cold-hardy. Of the repeat blooomers, rugosas are rock-hardy, and many
- Austins and other shrub roses will do okay. Many yellow and lavender
- roses are especially tender. Unfortunately cold-hardiness is not an
- exact science; conditions such as wind affect roses severely in cold
- weather (by drying them out), and so zone ratings are only a first
- approximation. Beware of books that rate roses 'cold hardy' or 'not
- cold hardy'---they are likely referring to conditions in the UK, which
- has mild winters. Beware also of catalogs that overrate cold-hardiness
- because they want to move more product.
- 2. When in doubt, plant own-root roses. If they die back to the ground in
- a particularly severe winter, they will grow back from the roots fairly
- quickly. This advice is not applicable to once-bloomers, because these
- usually flower only on the last year's canes. Own-root Old Roses and
- English roses are available. Hybrid Teas are almost always sold as
- grafted plants, and it is difficult to find own-root plants.
- 3. In the fall, reduce the amount of Nitrogen fertilizer used. This,
- combined with lower temperatures, will slow the production of new
- tender growth, and will allow the existing growth to harden off.
- 4. Stop deadheading about September 1 for zones 4 and 5. This will allow
- the plant to form hips. The formation of hips encourages the plant to
- slow down growth, slow blooming, and harden the canes, all preparing
- the plant for dormancy.
- 5. Understanding rose dormancy will help to determine the proper time to
- prune during the period from late Fall to early Spring. During
- dormancy, the sap has left the canes and the canes are simply empty
- tubes of cellulose. Pruning too early (before the sap runs back) cuts
- some of the nutrients out, so you must be sure the plant is dormant
- before fall (winter) pruning. Winter dieback generally occurs from the
- end of the branches (canes). Pruning removes the available length that
- can die back before reaching the ground. Also, pruning a semidormant
- plant stimulates growth and sap flow in the pruned region. For a plant
- going dormant, this is bad because it inhibits dormancy. For a plant
- waking up (springtime) it's good because it stimulates growth. Ideally
- pruning should occur before sap is fully flowing.
- 6. To prevent disease/fungus from overwintering, clean the rose bed by
- removing leaves and other debris. Spray the bush with dormant oil to
- kill bacteria on the bush and on the ground.
- 7. Protect the crown of the rose. This is critical since the crown is
- where you want the new canes to come from. There are several methods of
- protection to choose from.
- o Cover the bed at least a foot deep with tree leaves. Do not use
- rose leaves as they may harbor disease. Oak leaves are best as
- they seem to drain better.
- o Cover the bed with straw.
- o Use rose cones.
- o Make a mound with soil or mulch to cover the crown.
- o Wrap the whole plant in burlap if necessary, in addition to one of
- above methods of protecting the crown.
- Timing is important. Covering the rose too early is unwise as it may
- prevent the rose from hardening properly and will slow the onset of
- dormancy. Covering the rose too late may risk damage from the cold.
- 8. Climbers or long canes may benefit from being tied to avoid thrashing
- from the wind. Canes may be protected from drying winter winds by
- wrapping them in burlap with a layer of straw for insulation. In severe
- climates long canes may need to be tied and buried.
- 9. Keep the soil well-drained, especially as the spring rains come.

-
- ?? under construction
-
- 3. Diseases/Insects
-
- [3.1] My rose has black spots on the leaves, what do I do?
-
- Blackspot is a fungus that causes black spots about 1/16 to 1/2 inches in
- diameter to form on the leaves and sometimes stems. The infected leaves
- later turn yellow around the spots and eventually fall from the plant. In
- bad cases, blackspot can severely defoliate a rose bush. The conditions that
- promote blackspot are wet leaves, splashing water and warm temperatures.
-
- Here are some ways to combat blackspot. Most of these methods also apply to
- preventing and treating powdery mildew.
-
- 1. Pick a variety of rose resistant to blackspot. Many Rugosas are quite
- resistant to blackspot. Some yellow Hybrid Teas are especially prone to
- blackspot. However, yellow Floribundas such as Sunsprite seem to be
- especially resistant to blackspot.
- 2. Use watering methods that don't get the leaves wet: drip watering,
- using a soaker hose, or just soaking the ground with a light stream
- from a garden hose. If overhead watering is used, do so in the morning
- so the leaves can dry off before evening.
- 3. Remove all diseased leaves from the plant or ground immediately to
- prevent further spreading of the disease. Infected leaves never get
- better, they just spread the disease. Prune infected canes severely in
- late winter.
- 4. Prune away crossing canes and open the center of the bush to allow
- sunlight and airflow to more of the plant.
- 5. Blackspot is transmitted by water splash. Remove leaves close to the
- ground (the first 6-8 inches) which are more susceptible to getting
- water splashed on them. Mulch well to minimize water splashing onto
- leaves. If a plant had a lot of blackspot the previous year, replace
- the old mulch with clean new mulch in Winter or early Spring.
- 6. Keep the plant well watered. A weak or stressed plant is more
- susceptible to disease.
-
- Preventitive treatments for blackspot
-
- 1. The least toxic spray for blackspot is baking soda. Combine 1
- tablespoon baking soda and either 2 tablespoons horticultural oil or a
- few drops of Ivory liquid with 1 gallon of water. Mix as well as
- possible, and spray both sides of the leaves once a week. The Ivory
- liquid helps the baking soda stick to the leaves. Reapply after a rain.
- Baking soda changes the P.H. of the leaves, helping to prevent
- blackspot.
- 2. Another treatment is sulfur dust used every 7-10 days.
- 3. Finally, there are the more toxic chemical fungicides. They are often
- used once every week or two and are very effective. Follow the
- directions carefully. Be especially careful to spray properly in hot
- weather to avoid leaf burn. Spray the undersides of the leaves first.
- 4. Since a single fungicide may not completely wipe out all the fungi,
- using that fungicide over and over may actually cause fungus to build
- up a resistance to that fungicide. Alternating between two fungicides,
- such as Triforine (Funginex) and Daconil, is recommended to keep
- resistant fungi from building up. Fungicides generally can prevent
- blackspot, but do not cure an existing case of blackspot.
-
- [3.2] How do I avoid powdery mildew?
-
- This fungus forms a powdery white or grayish coating on the upper surface of
- young leaves and sometimes on the buds. Infected leaves crumple and become
- distorted.
-
- Unlike blackspot, wet conditions actually inhibit the development of powdery
- mildew. It can not reproduce in water. It thrives during high humidity but
- forms on dry leaves. Warm dry days, cool dry nights are ideal for powdery
- mildew.
-
- One of the best ways to avoid powdery mildew is to keep things as airy as
- possible. Roses planted too close to a wall may not get enough airflow.
- Prune away crossing canes and open the center of the bush to allow sunlight
- and airflow.
-
- Also, spraying the foliage with a mixture of 1 T. baking soda per 1 gallon
- of water can be effective.
-
- [3.3] How do I get rid of aphids?
-
- Aphids are tiny insects about a 1/16 to 1/8 inches long, usually light
- green, red or black. They come in the spring and damage tender new growth.
-
- A hard spray of water from the hose will help remove aphid infestations.
- Aphids reproduce quickly and this may need to be repeated every couple days
- for a couple weeks.
-
- Aphids have a mutually beneficial relationship with ants, so ants need to be
- controlled if aphids are to be controlled. Ladybugs are a natural predator
- of aphids and can be used to control aphids. Water the area well and release
- the ladybugs around sunset to discourage the ladybugs from leaving.
-
- [3.4] What is eating holes in the leaves of my rose?
-
- Leaf cutter bees cut semi-circle shaped holes in the leaves of roses. They
- pose no real threat to rose health, but they drive exhibitors crazy.
-
- 4. Rose Characteristics
-
- [4.1] Which is the most fragrant rose?
-
- Here is a list of some very fragrant roses as recommended by posts to the
- newsgroup rec.gardens.roses.
-
- * HT: Double Delight (mentioned most often), spicey, red-white bicolor
- * HT: Fragrant Cloud, reddish-orange
- * HT: Mr. Lincoln, dark red
- * HT: Crimson Glory, red
- * HT: Chrysler Imperial, red
- * HT: Papa Meilland, dark red
- * HT: Perfume Delight, pink
- * HT: Secret
- * ER: Gertrude Jekyll, pink
- * ER: Othello, dark red
- * ER: Heritage, lemony scent, pale pink
- * Alba: Felicite Parmentier, once-blooming
- * Damask: Mme. Hardy, white, once-blooming
- * Tea: Sombreuil, cream-white
- * Bourbon: Souvenir de la Malmasion
- * HP: Souvenir du Dr Jamain
-
- As a group, David Austin roses are quite fragrant. So are many of the Old
- Roses, such as the Damasks.
-
- [4.2] What kind of rose do I have?
-
- When posting this question to the newsgroup, include as much information
- about the rose as possible, such as the following:
-
- * what kind of rose is it? (climber, Hybrid Tea, Old Rose, Species, etc.)
- * approximate plant size (4ft tall by 4ft wide)
- * flower color, bud color, flower size (4 inch diameter),
- * approximate number of petals per flower
- * foliage color (light, medium, or dark green)
- * foliage description (dull, shiny, leathery, large, small, etc.)
- * how many leaflets per leaf on average (3,5,7, etc.)
- * once blooming (blooms once a year) or repeat blooming
- * thorns (many, few, large, hooked, straight)
- * fragrance (none, light, heavy, spicy, fruity, tea, etc.)
-
- [4.3] Are there any Blue roses?
-
- Though highly sought after, no blue roses exist yet. Some roses are
- advertised as blue, but they are actually lavender or something. Most
- lavender roses are difficult to grow and are quite susceptible to disease.
- Some of the bluer roses are Blue Girl, Blue Jay(HT), and Reine des
- Violettes(HP). A couple of true purple roses are Cardinal de Richelieu and
- Veilchenblau.
-
- The genetics are just not there for producing a true blue color in roses. It
- will probably be necessary to use gene splicing to produce the first blue
- rose.
-
- [4.4] Are there any Black roses?
-
- No true black roses exist. Some roses sold as black roses are actually dark
- red or maroon. The petals of many of these dark red roses tend to sunburn
- easily. To see that a rose is not truly black, hold it up next to a piece of
- black construction paper. To make a dark red rose appear blacker, put its
- stem in water that has black ink in it.
-
- Below is an incomplete list of some roses that have been mentioned when
- black roses are discussed. Next to some of the roses a very subjective
- description of the color is given.
-
- * Black Jade: dark red miniature
- * Cardinal de Richelieu: dark purple Gallica
- * Chateau de Clos-Vougeot: HT, deep red blossoms, blackish highlights,
- poor growth
- * Francis Dubreuil: Tea rose
- * Guinee: very, very dark red
- * Mr. Lincoln: HT, dark red
- * Nuits de Young purple Moss rose
- * Oklahoma: HT, deep crimson
- * Souvenir du Dr Jamain: Hybrid Perpetual, dark red/maroon
- * Sympathie: deep red climber
- * Taboo: Popular dark rose that has deep red flowers with darker edges.
- It reportedly has nearly black buds.
- * The Prince: English rose, very, very dark red/purple
- * Tuscany Superb: Gallica, deep maroon velvet
-
- [4.5] What are David Austin roses or English roses?
-
- In 1969, English Roses, often called David Austin Roses, were introduced by
- the English rose hybridizer David Austin.
-
- David Austin tried to create roses that combine the best elements of Old
- Roses (roses varieties from before 1867) and Modern Roses (such as Hybrid
- Teas, Floribundas and Grandifloras). Most English Roses have flowers
- resembling Old Rose flowers, cupped and rosette-shaped old-fashioned
- flowers, usually with many petals. English Roses generally repeat flower
- well, like the Hybrid Teas and other Modern Roses. English Roses are
- available in a wide variety of colors, such as yellows not very common in
- Old Roses. Many English Roses have the strong fragrances of some of the Old
- Roses.
-
- There is a FAQ article called 'English Roses' which is part 6/6 of the FAQ.
-
- 5. Miscellaneous
-
- [5.1] How do I propagate roses?
-
- There are two primary ways to propagate roses. Asexual reproduction is
- usually used to produce a duplicate of the parent plant. Sexual
- reproduction, i.e. growing roses from seed, is primarily used to create new
- varieties of roses.
-
- Common methods of asexual propagation of roses are softwood rooting,
- hardwood rooting, and bud grafting. Limited space permits only a brief
- description of softwood rooting.
-
- Old Roses, English Roses and Miniatures are generally good candidates for
- rooting cuttings because they usually grow vigorously on their own roots.
- Modern Roses such as Hybrid Teas and Floribundas are usually sold budded
- onto different rootstock. Some Modern Roses do grow vigorously on their own
- roots, while others do not. Below is a description of softwood rooting from
- Karen Baldwin with some changes.
-
- ROSE PROPAGATION A LA ZIPLOCK BAGGIES
-
- MAKING THE CUTTING
-
- * Preferably take a cutting on which the bloom is barely spent, so that
- all the petals have just recently dropped off. It is okay to take a
- cutting earlier, but at least make sure color is showing in the bud.
- These are indications of the maturity of the wood in the stem -- you
- want something in between the extremes of greenwood and hardwood.
- * Try to have at least four separate leafsets under the bloom, and a
- five-leaflet set at the bottom of the cutting. (Each spot where the
- leafsets meet the stem forms a "node," where the bud eyes are, and from
- which roots can form. Hybrid teas tend to have fewer "nodes" spaced
- farther apart than Old World roses, and thus require a longer cutting,
- generally speaking). Make a clean bottom cut with a sharp, clean
- pruning tool 1" below the last node. Try to leave about 1/2" of cane
- above the top leafset.
- * Keep your cuttings fresh in water while you gather more, until you're
- ready to plant them.
-
- PLANTING THE CUTTING:
-
- * Fill a 1-gallon zip lock baggie 1/4 to 1/3 full (about 3") with STERILE
- loose potting mix. (e.g., 1/2 peter's potting soil and 1/2
- vermiculite). A 2-gallon ziplock baggie may be better since it will
- give the leaves more room, but use the same depth of soil you'd use in
- a 1-gallon baggie, since you'll be watching for roots growing through
- it, later.
- * Moisten the mix but do not make it extremely wet. Use 1 tsp. miracle
- gro per 1 quart of water, to provide some initial nutrients (which may
- help avoid yellowing and leaf-drop). With your hands, firm the soil
- down well, within the baggie. The soil should be very damp, but there
- should be no standing water in the bottom.
- * Snip off the stem a little above the top-most leaf set (i.e., remove
- the flowering part). Try to leave about 1/2" of cane above the top
- leafset.
- * Strip off the bottom two sets of leaves (where the stem will be pushed
- into the soil).
- * Score the bottom part of the stem along its length (vertically) for an
- inch or so. (An exacto-knife works nicely for this purpose, but
- fingernails will do fine.) Roots will form along this score.
- * Dip scored end of cutting into rooting compound, a couple inches deep.
- Knock off the excess (you can get too thick a layer). Stick the cutting
- a couple of inches into the soil.
- * If insects have eaten the leaves during previous rooting attempts, you
- may wish sprinkle a very small amount of diazinon or other insecticide
- on the soil surface. Be especially careful if you are using chemicals
- indoors.
- * Mist the cutting and the interior surfaces of the baggie with a spray
- bottle filled with the following mix (to avoid fungus and mildew growth
- in the closed "terrarium" environment). Do not use spraycan fungicides
- or insecticides ... in the closed environment, the chemicals can
- overwhelm then kill a new young plant. 1 quart water 1 tsp. miracle gro
- 1 tsp. baking soda (no more!) 2-3 drops dishwashing liquid (to make it
- cling)
- * Zip baggie almost shut. Breathe into it 'til it expands kinda like a
- balloon, and zip the rest of the way closed. (Keep it closed unless it
- deflates enough to warrant breathing into it again.)
- * Put in bright, INDIRECT light - (e.g., behind sheers in a
- southeast-facing window) WARNING!!! if it gets direct sun or too much
- heat it will scorch (eventually turning black) and likely die! You may
- have to experiment a bit to find the best exposure; you might hedge
- your bets by placing some in different locations until you find the
- best spot for your house.
- * Clear away any leaves that might drop from the stem, reinflating the
- baggie after removing them.
-
- POTTING THE CUTTING:
-
- * Look for roots along the bottom of the baggie in two or three weeks. A
- few stubborn ones may take six weeks, and there is a report of one
- incredibly obstinate plant that took over 10 weeks!
- * Acclimation to air outside the bag is tricky. To be careful, (1) when
- you see some top growth, unzip the baggie just a little for a few hours
- the first day, then seal it up again. (2) For the next few days, unzip
- the baggie the same amount, but leave it open for a few more hours each
- day. (3) Next, leave it open all the time, but increase the amount the
- bag is unzipped each day for about a week, until it's fully open. Don't
- rush it.
- * Put good soil into a 1-gallon pot, leaving room for the addition of the
- new plant and its soil. Place the baggie atop the soil, and cut the
- plastic away (this can be slightly tricky). Firm the soil around the
- plant only very lightly.
- * Keep the same lighting in the same location (protected from too much
- direct sun) for a week, leaving the cutting unmolested to give its
- disturbed roots a chance to heal.
-
- PLANTING OUTDOORS:
-
- * After they have spent a week in their pots, you can either move them
- into more light inside for the first winter), or (preferably) move them
- outside.
- * When moved outside, set them in indirect sun at first, bright but
- shaded, and leave them there for a week. (If your area gets cold at
- night, you may need to move them inside at night for a while.) The next
- week, move the plant bit by bit toward and then into full sun. (Note:
- Gro-lights don't normally put out nearly enough light for roses, though
- it can probably be done.)
- * When kept inside for their first winter, especially in zones 5 and
- below, place them in a spot where they'll get more light. (When planted
- outside in the same summer they were rooted, even with a heavy mulch,
- many more will be lost to winter kill since the new little roses won't
- always have enough roots to carry them through. Also, chinooks
- (intense, warm winds) do their damage too. By keeping them inside for
- their first winter, and planting them in the spring, they will be
- better-established by the next fall.)
- * Plant late enough to avoid those nasty springs that get warm, causing
- the roses to break dormancy, only to follow up with a hard freeze!
- * Remember that your rose will grow in size; prepare a good-sized area of
- soil with added organic material as appropriate to your locale.

- [5.2] What is an ARS rating?
-
- An ARS (American Rose Society) rating is a yearly rating from 1(worst) to
- 10(best) given to a variety of rose. This is a U.S. national rating,
- combining several district ratings. The district ratings are an average of
- individual ratings given by rose growers, beginners to experienced.
-
- The ARS ratings are print yearly in the "Handbook for Selecting Roses". It
- can be obtained from the address below:
