just how important is medium/water pH?
When I get a new plant, I google its care and make notes for light, temp, humidity/watering needs, fertilizer advice, how to propagate, when to repot etc. Research is always a fun part of caring for house plants, I think. However, I almost never come across mentions of a plant's preferences for alkaline/acidic environments - generally only if I stumble upon commercial propagation/growing documents or for a very short list of plants where the effect is obvious (blueberries like low pH, hydrangeas turn pink or blue depending on the acidity - that sort of thing). Should a hobby home grower like me with 30-35 various plants even be looking harder? Just how important is pH of water and the medium for your typical home plant?
I grow mostly tropical foliage, all indoors. I have been adding vinegar to my water just because *generally* I understand plants like more acidic water, while municipalities including mine keep their water more alkaline to increase the life of supply pipes and other equipment (to reduce corrosion basically).
I was just thinking of getting pH testing strips or a solution and to see how much vinegar would bring my water pH down to the ideal low-5-ish, but then I thought, while an interesting chemistry experiment, how much am I really fooling myself with how important this stuff is objectively.
