|What may I put inside the bottom of each planters for good drainage?I have some broken concrete pieces that I could use instead of gravel,that I have found around the house.How may I position them so the drainage holes will not get stopped up by soil? There is also large blocks of concrete under each planter in the ground to help. Thank you for your help.

|If you're concerned about the potting soil draining out of the bottoms of the planters, you can place pieces of with window screen over the drainage holes or you can simply put a paper towel or paper coffee filters over the holes before filling the planter with potting soil. Gravel and broken concrete won't really stop particles of potting soil from rinsing down and out of the planters. I'd simply place paper coffee filters over the holes before filling the planters with potting soil. It works quite well.
