Cut the bottom off a plastic pot to contain invasive plants & bury in the ground. I have been doing this for a few years & works great for containing plants that tend to spread, but that I still want to plant in the garden. This also works good for planting a plant in an area that tends to get filled with roots etc. from other plants. I will use a larger pot so that the plant can spread it's roots and grow deeper roots, but keeps other tree roots from choking out the one I planted.
When I was in the Master Gardener program we used the water crystals in planters and I knew it was the same thing in diapers, but it never crossed my mind to put a diaper in the bottom of one. Someone else said, "The trick to amazing potted plants - diapers. I did this in my hanging baskets last year and they rocked all season."
