Question: What is the best and easiest way to fertilize plants in my greenhouse?

Answer: Use a siphoning proportioner installed between the faucet and your garden hose, or install a fertilizer injector in-line. Read the installation instructions carefully, and check with your city to make sure you’re meeting all of their safety codes to prevent backflow of the fertilizer solution into your water source. It might be best to use a licensed plumber for this installation. You may also want to use timed-release encapsulated fertilizers.
