Can water quality affect orchid fertilizer efficiency?
Living in Vancouver, I've noticed that the water quality can vary quite a bit, especially between tap and rainwater. I understand that orchids are sensitive to their environment, and I'm curious about how the quality of the water I use affects the efficiency of the fertilizer. I've been using a balanced orchid fertilizer but sometimes wonder if my tap water, which has higher mineral content, is interfering with nutrient uptake. Have others experienced similar issues? What types of water do you find work best, and have you made any adjustments to your fertilization routine based on water quality? Any tips on water testing or filtration would be greatly appreciated!
