Hi Linda,

Houseplant food contains nitrogen (N), phosphorus (P), and potassium (K). A fertilizerPlants need fertilizer only when they are actively growing. Slow growing plants in low light require very little plant food. Too much fertilizer is worse than not enough. Most plants prefer a water soluble plant food at 1/2 the recommended strength. Plants that are in bloom or dormant should not be fertilized. Houseplant food contains nitrogen (N), phosphorus (P), and potassium (K). A fertilizer containing these elements in equal proportion is considered a balanced plant food. Nitrogen helps in photosynthesis and encourages the growth of leaves and stems. Potassium and phosphorus also help in photosynthesis and aid in root and flower development. Most fertilizers have trace elements of other minerals that are lacking in the soil but are necessary for good plant growth. Fertilizers have a high salt content. If a plant is not producing new leaves and doesn’t absorb the fertilizer, salts build up in the soil. These salts can burn the roots, discolor the leaves, and cause new growth to be small. containing these elements in equal proportion is considered a balanced plant food.

The numbers 10-15-10 indicate that the plant food contains 10 percent nitrogen, 10 percent phosphorus and 10 percent soluble potassium.

Never use a plant food if the soil in very dry. I like to use a Fish Emulsion plant food or Blood Meal for leaf development.  During the blooming season in later winter or spring, switch to a high-phosphorous fertilizerPlants need fertilizer only when they are actively growing.

In addition, you can also use a product called superthriveSuperthrive combines vitamins and hormones to encourage plant growth both above and below the soil line. It's not a plant food so it needs to be used in addition to your regular plant food; the two can be used at the same time. Just put a few drops into your watering can & that's all that's needed to improve the health & appearance of your plants. If your plants are in real trouble, add about 10 drops per 2 gallons of water. SuperThrive works best when the soil is dry.    . superthriveSuperthrive combines vitamins and hormones to encourage plant growth both above and below the soil line.
