Container Vegetable Gardening: High Yields in Pots, Tubs & Grow Bags
Urban balconies, front porches, and concrete patios can easily become thriving micro-farms. The secret lies in container volume, specialized potting media, and frequent feeding.
Minimum Container Sizes by Crop
Radishes and baby greens: 6 inches deep.
Bush peppers and compact eggplants: 5 gallons (12 inches diameter).
Indeterminate slicing tomatoes and squash: 10 to 15 gallons minimum.
Frequently Asked Questions
Why do containers dry out so fast in mid-summer?
Pots have exposed surface area on all sides that absorbs solar heat. Mulch the top of pots with 1 inch of straw and consider fabric grow bags or drip sub-irrigation.
