“What kind of fertilizer should I use to grow vegetables in a big container pot with potting soil?” Question from Susan of Union City, Pennsylvania
Answer: For containers, I always opt for a slow-release fertilizer that will feed plants well all season long. Choose one that is formulated for vegetables, fruits, and herbs. Most of these will have either a balanced N-P-K (Nitrogen-Phosphorus-Potassium) ratio, such as 10-10-10, or a ratio that’s more geared towards foliage growth (12-10-5) or fruiting (4-6-3). Just as a reminder, nitrogen encourages foliage growth, phosphorous generally supports flower, fruit, and root development, and potassium supports overall growth. Read the label and make sure the fertilizer you choose will accommodate the vegetables you want to grow. If you garden organically, pick an OMRI Listed fertilizer.
