- Which herbs did you plant? Most can take some root damage without any
- problem --- especially the ones that have been spreading so well. If you
- want to dispose of certain herbs completely, it may be difficult to get all
- of it out but digging is the only solution. I stupidly planted lemon balm
- in a small herb border, between some thyme plants, & had to be really
- merciless about digging it all out. I'm sure I'll see some sprouts in the
- spring, but they'll be alot easier to dig out than the original
- plant-from-hell. The neighboring thyme plants didnt seem hurt at all. So
- just get in there and hack away! You're in a much different zone, so I
- don't know when is the best time to prune or transplant --- check with the
- local cooperative extension, or maybe another CA resident on rec.gardens.
-
- DON'T plant anything from the mint family (including lemon balm) in a bed
- shared with other plants. In fact, put it somewhere in lousy soil, far from
- your garden, & HOPE that keeps it in check. I tried the trick of planting
- it in a 5-gal. plastic tub with the bottom cut out, buried up to the top
- inch or so, and the darn stuff still got out & infected nearby beds. So I'm
- not convinced that dividers work with that stuff. The only other pesky herb
- I've planted was borage, which self seeds readily and keeps popping up in
- the oddest places (nowhere near its original site). But it has pretty
- flowers, & is a magnet for cabbage & tomato caterpillars (which can then be
- destroyed), so it's not really a nuisance. Maybe you should consider pots?
- especially if you're not going to be around to keep the vigorous growers
- cut back & out of each other's space.
-
- In general, herbs don't need special treatment, and you shouldn't need to
- do anything special to your soil. Some (like tarragon & rosemary) prefer
- good drainage, so if your soil is very heavy/clayey, mix in some sand &
- organic material. Most books say NOT to fertilize, at least not before
- you're going to pick the plants (otherwise your thyme might taste like fish
- emulsion, yecch).
-
- Rodale Books put out a good reference book on herbs, but unfortunately i
- don't have the name handy. It has extensive information on cultivation &
- all sorts of uses, from medicinal to culinary to decorative. Good luck!
