Tomatoes Tomatoes thrive in buckets, especially cherry and bush varieties. Use a 5-gallon bucket with drainage holes and a sturdy support system to help the plant grow strong.
Peppers Bell peppers and chili peppers grow well in 2- to 5-gallon buckets. They need full sun and well-draining soil, making them ideal for patio gardening.

Carrots Carrots grow best in deep, loose soil, making a deep bucket (at least 12 inches) perfect for them. Shorter varieties like Nantes or Parisian carrots work best in containers.
Radishes Fast-growing and low-maintenance, radishes thrive in 2- to 3-gallon buckets. They mature in just a few weeks, making them a great choice for beginners.
