Do this in the fall. Spring bulbs in Pots: store the potted bulbs in an unheated garage or storage room. Youll need to water every few weeks since the pots wont have access to rainfall. In addition to small pots, pack bulbs shoulder-to-shoulder in big containers for an abundant display in spring. Toss aside the spacing recommendations so you can get as many bulbs into the container as possible. This is a great idea.
I so need to try this. 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."
