"Restricted Drainage Container Gardening"

I am still making and using new versions of an early progenitor to my Water Wise Container Gardens.......Restricted Drainage Container Gardens. They are easy and a tightwad's dream.....scavenge large used commercial black plastic tree pots, draw a rolled up used plastic grocery bag, half way, through each and every drainage hole so that half of each extends outside the pot. Set it in place, pile mulch around the base to hide the bags, then fill the pot with the soil/compost mix of your choosing. Soak it DEEPLY by hand, repeat an hour later, apply 2 inches of free chipped tree trimming mulch, then plant, then hand water again. This approach DOES allow the soil to drain, but SLOWLY. The large soil surface allows for good oxygen flow to the roots, especially if you bury a few handfuls of dry dog or cat food then add some red wriggler earthworms. This approach has allowed me to grow Old Roses, broccoli, hot peppers, okra and more despite south Tampa's perennial lack of sufficient rain. I also like to pee in them plus give them kitchen graywater as sources of both water AND nutrients. John
