Aphids on rose bush

Pest: Aphids

Now’s the time to check your plants for aphids (shown right) and whiteflies. These small, sap-sucking insects will cause the foliage on your plant to yellow and die.

A great, all natural way to get rid of these pests is to use ladybugs and green lacewings. Be sure to follow the release directions for the best outcome.

Neem oil, insecticidal soaps, and horticultural oils can also be effective against these insects. Bonide® Neem Oil® is a natural solution for use on roses, flowers, vegetables, herbs, spices, houseplants, trees, turf and shrubs. This multipurpose insecticide and fungicide controls blackspot, powdery mildew, rust, spider mites, aphids, whiteflies and more.
Peach leaf curl

Disease: Peach Leaf Curl

Peach leaf curl (shown right) is one of the most common diseases for backyard gardeners, typically affecting peach and nectarine trees. This fungal disease appears in spring on new growth, causing foliage to become thick, curled, and deformed. Check your trees and treat now to avoid further damage. Bonide® Copper Fungicide contains a special copper salts formulation that helps control fungus-related diseases.
Black spot on rose bush

Disease: Black Spot

Roses are showing off their big, beautiful blooms right now. But take a closer look to check for any disease. Black spot (shown right) is a fungal disease that is common this time of year. The fungus will develop black spots on the leaves, causing them to turn yellow and drop, weakening the rose plant over time. You can treat this now with Bonide® Copper Fungicide. In addition to roses, this can also be used on fruits and vegetables—perfect for the organic gardener.
