Dormant Spraying

Bushes stripped for pruning are ideal candidates for dormant sprays.  These special spray materials are formulated to clean up any diseases a bush may be sheltering and provide a healthy environment for the coming new growth.  They're quite safe and easy to use.  There are many on the market, most with a base of sulfur, which is known for its effective disease eradication.  If you plan to use a dormant spray, and I urge you to, please do it at this point.  The spray is not meant for the new growth that will be appearing rapidly once you've stimulated the bush to provide it.

While you're at it, spray the soil around the bush as well.  This area can harbor disease spores left from fallen leaves and cuttings, and dormant spray will safely knock them flat.
