Phoenix ~2008 I think I had small wheels on them attached at the bottom 4 plcs. I had a concrete patio to roll them around on.

I have moved these small shade houses from Moorpark Ca to Phoenix Az to Poway and then back to Moorpark. I finally am getting around to setting them up level and straight and noticed alot of flowers on my cactus. So I'm attaching some pictures. I have to secure them together at the handles when the ...

I've had soil like that. Try adding more course sand.

I think the PH is high around 8 but I never measured it. Wolf Creek ranch on Ebay has a bunch of info on it. I think they eat it over there ? I thought...

Winter time it was close to the climate of Phoenix AZ and moved apart every month after that. Its probably frying in Phoenix right about now. I am tryin...
