Never use these products on plants that have hairy leaves, such as African violets. The best way to clean leaves that are not hairy is to dampen a soft cloth with water and wipe the lower and upper surfaces of each leaf. An alternative is to place the entire plant outdoors or in the shower to rinse it off. Plants with hairy leaves should not be dusted with a wet cloth but with a soft cosmetic brush. A pressure sprayer may be employed.
All plants require certain essential elements for proper growth.
Indoor plants, in low light conditions of the interior environment, have reduced fertilizer requirements. Observation will guide you in determining a plant s fertilizer needs. This is usually in the spring and summer when sunlight intensities increase and the days are warmer and longer. If plants go into a winter rest period, do not give them fertilizer. Frequency of fertilizer application varies somewhat with the vigor of growth and age of each plant.
