Yes, you can grow dwarf peach trees in an outdoor plant box! Dwarf peach trees are ideal for container gardening due to their compact size, typically reaching 4-6 feet tall. To ensure success, choose a large, sturdy plant box (at least 18-24 inches in diameter) with proper drainage. Use high-quality potting soil mixed with compost to provide nutrients. Place the box in a sunny spot where the tree receives 6-8 hours of sunlight daily.

Water the tree regularly, keeping the soil moist but not soggy. Fertilize during the growing season with a balanced fertilizer to promote healthy growth and fruit production. Prune annually to maintain shape and encourage airflow. With proper care, your dwarf peach tree can thrive in a plant box and yield delicious, homegrown peaches.

Container-grown peach trees also offer flexibility—you can move them to protect against extreme weather. Just ensure the box is manageable in size. Happy gardening!
