Adventures of a beginner gardener in Volcano

[Les C]

I'll bet that, these days, it makes a lot of sense for Puna growers to test for acidity in the air and rain. Maybe litmus test a rain gauge? Also, many fruiting plants may grow at Volcano's elevation, but they may not fruit. Maybe because of the average temperature?

It might make sense to fashion a greenhouse and maybe use some grow lamps to fill in where the sunshine and warmth may be lacking.
