By Angie Noack, Fri Dec 9th
Heat is one of the worst enemies that roses face, and the monthsof July and August can be scorchers. Not only are your roses atrisk of heat damage, but the accompanying humidity breedsinsects and fungal diseases. Here's a look at what we can do to keep our roses beautiful andhealthy until the cooling days of autumn arrive. Make sure that your roses have all the water that they need.Remember to water from the roots and not from the top to avoidfungus development and to make sure that your bushes can drinktheir full.
Water daily when the temperature is at or above 90F. Pot-grownroses may need to be watered twice per day. Avoid wateringduring the hottest times of day to guard against excessiveevaporation. Spray fungicide on a weekly basis to keep these humidity-borndiseases at bay, and cut back canes and foliage which show anysigns of infection. Apply light feedings of fertilizer at least three times perweek. Don't over-fertilize as this will cause burning. Apply 2 to 3 cups of organics weekly, and stop applying yourorganics during the last week of August. July and August are prime times for spider mites who thrive inthe heat and humidity. Spritz your foliage and buds with wateron a regular basis to show these pests that they are not welcomeon your roses. Now is not the time to fall behind on your deadheading chores.Your canes need all of their strength to support new growth, sopay careful attention. Start cutting back your roses in the latter part of August sothey will be ready
