20 Gallon Black Nursery Pot

20-Gallon Heavy-Duty Nursery Pots, Extra-Large Containers for Trees and Specimen Plants

For gardeners and growers who think big, Green Oasis 20-gallon nursery pots deliver the generous root space needed to grow fruit trees, specimen shrubs, and high-yield container gardens. Sized between our 15-gallon and 25-gallon pots, the 20-gallon is the natural step up for plants that have outgrown their current container but don't need the largest pot in the lineup. Each pot is injection-molded from commercial-grade HDPE plastic, giving you the structural strength to handle heavy soil loads without bowing, cracking, or deforming over time.

Built Tough With Injection-Molded HDPE

Blow-molded nursery pots are thin, uneven, and turn brittle after a season or two in the sun, which is a real problem when a pot is carrying a full-size tree. Green Oasis 20-gallon pots are injection-molded under high pressure to produce thick, dense, uniform walls that keep their shape when filled with heavy, wet soil, stand up to being moved around the yard or nursery, and perform like new season after season of outdoor use.

Grow More With 20 Gallons of Root Space

Container growing is all about root volume. The more space roots have to explore, the larger and more productive your plants become. At 20 gallons, these pots let you grow trees and shrubs that most gardeners assume require in-ground planting. Move mature specimens around your patio, protect tender plants over winter, and keep full control of your soil, water, and growing environment.
