Water and Fertilizer
Keep in mind, containers that are really full, very small, or in sunny and windy places will need water more often. Watering in the morning to prevent stress is best.Container plants need regular feeding. If your potting soil doesn't contain fertilizer, add a slow-release fertilizer, or regularly feed with a water-soluble fertilizer.
Great container varieties
Don't rule out crops you thought were too big for containers. Choose compact varieties.
The same goes for root crops like beets and carrots. Use a deeper pot for these delicious roots and choose a small variety like Tonda di Parigi carrots, or harvest beets at a smaller stage.
