We have bought this plastic Fountain planter/raised garden bed. The trouble is it doesn't drain the water resulting into submerged plants in the water. I assume its caused by the overflow openings in the legs getting clogged with the soil?
I read about covering the overflow x 4 openings with weed mesh or sometheing like that.
More importantly, are these planters supposed to be filled up with potting mix well over the overflow openings?
Thanks.
