Yes, and although someone told me they were good, they didn't do anything for me here. I'm in South Florida, the ground stays warm anyway. The holes for "irrigation" kept getting plugged with dirt and other debris. The collars aren't that big and don't conserve that much water. You're much better off mulching with an organic or plastic mulch.

This year will only be my second. Had alot of fun growing tomatoes last year & received an ad for something called tomato boosters. They are a black plastic collar that has a reservoir surrounding the whole that the tomato plant comes through. They say the reservoir is made for drip irrigation, that is has a cup for granular fertilization and that the collar helps with cutworms & weeds. They sell for 6 for $9.00. The price sounds reasonable. Has anyone used them? Thanks, Kim
