Yug

When I plant a banana, I give consideration to depth based on the soil dampness, and wind factor. I don't want it so shallow that it dries out quickly, and that the roots don't provide a solid anchor point to keep it from blowing over. If it is a really small seedling, I would probably keep it potted until at least 3 ft tall, and then put it about 8 to 10 " deep. Larger 'pups' would be 1 to 1 1/2 ft deep. The hole would be generously laced with composted steer manure to provide some nitrogen.
