I have several trees I've been want to plant all season, but the areas I will be planting in can hold a lot of water when we get our seasonal downpours. Because of that, I'm wanting to plant the trees 1-2' above the ground level, so they'll be able to handle standing water better. I have a huge roll of RootBuilder, what I'm thinking to do is cut 1-2' tall strips of it (with the appropriate ring size) and plant the trees high (something like what member MarkInTexas does in his greenhouse). I'll expand the RootBuilder rings as the trees get taller, eventually I'll try removing the rings and mulching the tree mounds.
So, all that said, my two concerns are the abuse the RootBuilder pots will suffer when the grass around them is cut (riding mowers and weed-eaters will take their toll) AND the aesthetical appearance of the RootBuilder container itself. I've been hoping to stumble upon some durable, flexible-sized plastic/PVC that I can cut to loosely wrap around the RootBuilder to protect it and make the plantings looking more appealing. Anybody have any suggestions? All I can think of (that exists) is finding some of those large food-grade (water-storage) barrels/drums and cutting them to size.
