How do I get Houseplants to Produce More Leaves?

My angel-wing begonia needs leaves! The Schultz Plant Food is 10-15-10. Isn’t that high in potassium? I’ll worry about flowers later. Now, I need leaves, foliage. Can you name some brands of food I might use? I thank you in advance!!

Hi Linda,

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. The numbers 10-15-10 indicate that the plant food contains 10 percent nitrogen, 10 percent phosphorus and 10 percent soluble potassium. You need to use a fertilizer high in nitrogen (first number) weekly at one quarter the recommended strength or biweekly at one half the recommended strength for your begonias. 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 fertilizer. In addition, you can also use a product called SuperThrive. SuperThrive combines vitamins and hormones to encourage plant growth both above and below the soil line. It’s not a plant food so it can 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. If your plants are in real trouble, add about 10 drops per 2 gallons of water.
