My brother is at over 8000 feet and we are at just over 7000 feet, with lots of pests. as the drought continues we are seeing animals that weren’t here before and black widow spiders (found in the wood pile) this year.
Yes, the key holes have been very sucessful in sub Sahara Africa, Texas, Oklahoma, California and other drought areas here in the US. According to what I read three of them will usually feed a family, however as you and I know we have a very limited time of year we can garden with out a green house. I think they are using them with sucession planting which as you know won’t work here. But anything helps for us so….
I read of one in Colorado but they didn’t say where or what altitude so could not gauge how sucessful it would be here. ahh dreaming of a more productive garden!
