I bought these because my husband planted tomatoes in pot - we recently moved from WI to AZ. Frequently it is very windy here and I have been trying to keep his plants upright. We have tried many things-using camper-tent stakes, putting rocks in the pots, etc. These top hat stabilizers are the best! No more blown over plants.
I grow Plumerias and they can be very top heavy. Every time we have a rain storm I'd have to pick up dozens of turned over plants. I saw these top hats at a local nursery but they wouldn't sell me any. I came home and googled top hat and found these. This is my second order and I just love these. They are very stable and the service was great.
