Don't Plant These
8 Vegetables in Containers
2. Pumpkins/Winter Squash
If you’re determined to grow them in a pot, consider containers that are at least 20-25 gallons.
Melons–cantaloupe, watermelon, honeydew–are heavy feeders with deep root systems and a wide spread, making container gardening difficult.
While garden soil is fine if they’re planted in the garden, a looser, lightweight soil is necessary for container growing so roots can breathe without becoming compacted.
Potatoes need a lot of underground space, which can be difficult to come by with a pot. Container-grown taters need frequent watering, well-drained soil, and fertilizer.
Eggplants need a lot of space, so if you’re set on container-growing these purple fruits, a large pot would be necessary. A trellis with support for heavy fruit will help save the harvest.
