potting soil mess
I put pots of annuals out on the pool pavers for the winter and it became a big mess. I used regular bagged potting soil and it floated up and out and down and out. Now we have weed fields where the soil settled. I've removed the pots and transplanted the plants in the yard, and I'm cleaning up the mess.
It looked nice while it lasted. It gave the patio area color and interest and I could bring the smaller pots indoors when the nights became too cold.
There must be simple solutions to this problem. I remember someone saying they used coffee filters on the bottom of the pot. Window screen? Mulch on top or rocks to hold the soil in?
