I only have one hypertufa trough garden, although it's not for lack of trying. I attended two workshops & made two but I think they were too thick & they cracked of the winter, so I purchased this small one at a local nursery. It hasn't cracked yet, 2 winters. I wish I hadn't left the plant markers in but it was the only way to remember what was what. Maybe I'll take one without the markers but the garden certainly is different from when I took that picture. Anyway, I do want to put some miniature thingies in the garden.
Yes, this is the formula, but you have to be careful of making them too thick & also, it helps if you put chicken wire inside while you are forming the trough. I do leave mine outdoors in the winter with no ill effects.
Buttoneer: What variety of campanula is that? It looks like spiral bellflower/fairy thimbles (Campanula cochlearifolia). They are a wonderful rock garden plant... nice trough and good selection of plants!
5 years later. Weezingreens, I am sorry I never answered your question. My trough garden is now 5 years old & different plants are in it. The only plant that survived was the ornamental flowering chives upper left & literally took over, so I removed 3/4 of it and potted up the rest in the GHSE. I planted more Leptinella in it, plus some more plants, which I can't remember now. I'll take a pix & put it here so you can see how it looks in 2007. I did manage to make another trough that has lasted 2 years now. Will take pix.
Thanks for the reply, no matter how belated it might be! LOL! Well, I'm glad to hear the troughs are holding up. I think it is difficult to keep plants in containers over the winter. Ceeads puts alpines in hers, and they seem to do well. I don't know if she moves them into the greenhouse in the winter or just tucks them under her porch. She uses local alpines, sedums, etc. I've just got to make some troughs!
Weez, they're easy to make, just messy. I am taking the Leptinella in for the winter. It has never proven hardy for me here in PA & I can put it in a little pot & winter it over in the GHSE. I finally hung out a whole bunch of hanging baskets all around the greenhouse. Lots of Epi's. One more week to go before threat of frost is over, but I was chafing at the bit.
We aren't safe from frost until the end of May here. I have one greenhouse going with heat and a tent going up that will also be heated. The old unheated greenhouse has a new skin of plastic, so I'm gearing up for the season. It seems to be slow in warming this spring... probably easier on the wintered over perennials in pots. The sudden spring hot spells followed by freezing really raise havoc.
