I love the Kozy-Coat teepee's and what they do to give me a head start on my garden, in the Spring. I live in the P.N.West and am at 1000', in elevation, so these teepee's are a blessing. But, after a few season's, they well wear on the bottom chamber and sometime's form a leak.
This is where the repair sleeve's come in handy. Rather than fussing with a flat on one side, leaning teepee, simply inserting the repair tube and filling it up makes the Kozy-Cote stand as it should and the plant has all the protection and help it should.
Sure saves from having to buy another teepee or trying to repair the hole with a tape or glue.
