Fertilizer Practices
Even though the metabolism of plants growing in the shade is slower than that of those growing in the sun, they still need a steady supply of nutrients. Monthly application of a comparatively mild complete fertilizer is a good practice when the plants are actively growing. A mild fertilizer might be a liquid fish emulsion with a 5-1-1 formulation, or a dry 5-10-5 fertilizer. (The numbers refer to the percentages of nitrogen, phosphorus, and potassium contained in the fertilizer, and are always listed in that order.
Acid-loving plants can be given special fertilizers that have an acid reaction in the soil. These fertilizers are usually labeled “azalea and camellia food,” “rhododendron and azalea food,” or something similar.
No matter which fertilizer you use, always follow the directions on the label carefully. The rates and times for application have been the subject of much research and should not be taken lightly Too much of any fertilizer can quickly damage plants.
