I'll try one to keep my eyeglasses from fogging. I bought a new pair and said "no" to the anti-fog coating. That was a mistake!
I agree that roots grow into and through window screening if you use that to block pot holes. Nasty. Unless you want to call it deliberate root pruning.
Does the dryer cloth hold roots in, or do they push right through it?
My only method for blocking big pot holes in the past was to hand-pick extra long shreds and chunks from screened pine bark mulch, and pile some of those around each hole. Like the ancient, classic method of saving broken clay pots and piling shards around potholes.
But I think the abrupt change in texture between the soil mix and the bark shreds and chunks interfered with capillary "continuity", so that the bottom of the pot held more perched water and prevented wicking the pots by setting them on absorbant mats.
Last summer I got lazy and didn't move some 1 gallon pots with Lobellia, sitting on heavy clay (can't call it soil). Some soil mix came out of the holes and formed a bridge onto the clay. Those poor roots followed the bridge and TRIED to push their way into the clay. Fat chance! They circled around under the pot and above the clay, like an external root ball or a living capillary mat.
P.S. I read that you can wipe a new dryer anti-static sheet on the OUTside of a Ziplock to keep very fine seeds from trying to float away from or cling to the plastic. I never tried it, because my humidity always prevents "seed levitation".
