Pruning dead blooms and leaves keeps your plant beautiful and healthy! Dead blooms and leaves steal nutrients from your plants, so pruning with quality pruning shears, such as Fiskars Traditional Bypass Pruning Shears (9109), will energize your plant. It also gives you an opportunity to inspect the plant for insects and disease. If you do discover insects damaging your plant, we have had excellent results with an organic insect killer Safer Brand 5118 Insect Killing Soap – 16-Ounce Concentrate . To treat fungus and disease, we highly recommend Safer Brand Garden Fungicide Ready to Use 24 Ounces 5455 .
