Container Size Considerations
There are a few rules of thumb to follow in regards to container sizing for either peppers, tomatoes, or eggplants.
We recommend planting into a soil medium that is 1/3 compost, 1/3 peat moss, and 1/3 perlite. This will seem like a lot of perlite, but drainage is critical as your pepper, tomato, or eggplants do not want wet feet!
Recommended Minimum Sizes
Whatever material you choose, make sure that it has adequate drainage! This is done via a hole or holes in the bottom and being raised off the ground.
