Answer: Because the roots of potted plants are confined, they are more susceptible to fertilizer burn so the safest and easiest way to feed them is with a water soluable houseplant fertilizer. I use Miracle-Gro, Peter's and Shultz's (whichever is on sale at the time!) Use a half-strength dilution and feed every two weeks during the growing season. (i.e. one TBS. per gallon of water instead of the recommended two TBS.) Feeding every 2 weeks provides all the necessary elements to the plant roots without the fear of salt burn. Best wishes with your plants!
