Roses: As a preventive for fungal disease, spray plants weekly with a mixture of 1 tablespoon of baking soda and 3 tablespoons of horticultural oil to 1 gallon of water. Fertilize, except for the once-blooming varieties. Removing spent flowers keeps them from producing hips or seeds. When cutting roses for bouquets, cut each rose just above a bud so that at least two five-part leaves remain where the branch joins the main stalk. Avoid overcutting new rose bushes the first year.
Flowers: Honeydew on plant leaves may mean aphids. A strong spray from the hose will remove most of those pests. Most herbs need no fertilizer and little water, so water only during prolonged dry spells. They abhor chemical treatments. Avoid mulching herbs because mulching keeps the soil too moist and will encourage fungus. If this occurs, cut them back to encourage new growth.
Vegetables and fruits
Thin to 10 inches between corn plants and at least 8 inches between bean plants. Check potatoes for potato beetle. Hand pick as soon as they appear. Plant more lettuce as it will bolt in hot weather. Pick radishes before they grow too large and get too hot.
Trees and shrubs
Prune dead, diseased wood and water sprouts from dogwoods and magnolias. Prune hedges so that the bottom is broader than the top. Then the sun can reach the lower branches. Continue pruning spring-flowering shrubs.
Compost grass clippings. Spot treat weeds in the lawn.
Keep houseplants that have been moved out doors out of direct sun rays.
Control poison ivy with Roundup. Never put leftover pesticides or those transferred from damaged containers into unmarked containers or food or drink containers. Never store pesticides where they could contaminate human or animal feeds or leave the containers where rain can wash them into the ground.
