Six methods for preventing and controlling flower diseases
NO.1 Leek Water—Cures Dark Spots

The prevention and control of pests and diseases emphasizes "prevention first, integrated management".
★ Do not bring diseased or pest-infested plants home; when propagating, choose plant materials that are free of disease and pests.
★ Improve and strengthen cultivation management to ensure robust plant growth and enhance their resistance to diseases and pests;
★ Improving the environmental conditions of plants, such as improving ventilation and light, can reduce the likelihood of some pests such as scale insects and aphids, as well as many diseases; loosening the soil and controlling watering can reduce the likelihood of root rot.
★Observe your plants frequently, and deal with them as soon as possible if you find any signs of pests or diseases in your houseplants;
★Try to remove diseases and pests manually, or spray homemade "medicines" to treat and kill diseases and pests. For example, use a soft brush to brush away scale insects attached to the branches and leaves of the plant; wash aphids and spider mites with tobacco water or very diluted soapy water; prune and remove withered or diseased branches, leaves and flowers, and promptly remove fallen dead branches and leaves to prevent the growth and spread of pathogens.
★Based on the types of diseases (insects) that have occurred, purchase targeted low-toxicity pesticides from the flower and tree market and use them according to the instructions.
★For plants that are prone to disease or frequently get disease, fungicides should be used for prevention before the usual disease season.
