pH and Cactus
My Northern Garden lets us know that your local city water may be more alkaline than you think. And if you’re not thinking about it, then maybe you should get out a pH tester right now.
Malcolm (Burleigh) and one of his cactus-growing friends from California had discovered that city water tends to be much more alkaline than rain water and that the change in pH made a big difference in plant performance….
Adjusting pH for houseplants is one thingan entire garden is another. Malcolm uses a watering system that involves a sump pump, a 45-gallon garbage pail, and an octopus hose system.
Nice.
