When a single plant needs to stay in a container for years, or when you want to grow multiple plants together in one bag, 20 gallons is just the right size. At 20.5" diameter and 14.5" deep, this bag has the volume and lateral spread for crops and plants that outgrow smaller containers fast.
 
The best use cases: blueberries and other fruiting shrubs that need room to establish a permanent root system; figs, dwarf citrus, and other container fruit trees that will live in the bag season after season; sweet potatoes, which spread wide and produce more when they're not cramped; and multi-plant combinations, a full tomato cage setup with basil underneath, or three pepper plants sharing a bag.
 
The 300G thickened nonwoven fabric air-prunes roots through the wall, preventing the circling that limits long-term production in plastic containers. 
 
Washable and foldable for off-season storage. BPA-free.
Good for: blueberries, figs, dwarf fruit trees, sweet potatoes, multi-plant tomato and pepper setups, larger shrubs, permanent container plantings.
