I had a late start growing my coleus from seed this year. To give them a better chance to grow larger, I planted them in pre-fertilized potting soil in pots. My ivy beds beneath the pines were the perfect spot for the pots to sit. The vines were the perfect height and strength to hold the pots in place. Now some of the coleus are nearing twelve to eighteen inches in height. The wind has continually knocked them over in the last few weeks. To stabilize the pots and keep them from overturning I aligned short stakes with the drainage holes and hammered them into the ground. This has worked perfectly, a quick solution to a constant problem. I also thought a dollar store pack of pencils would have done the trick for holding the pots in place. Sharpened, and pounded in through the drainage areas, they would also keep the pots stable.
