Lesson 8 : How Often Should You Feed Your Plants? November 20, 2015 Growing Tips First Watch : Teachings Of The Garden Sage Lesson 8 What did we learn? The question being addressed is a pretty vague one considering the vast spectrum of different fertilizers on the market and their variances in concentration as well as the varying demands of your different species of plants. In this video the Garden Sage explains a test that can help you determine the perfect amount of fertilizer required and the feeding rate to help you achieve optimum results. This involves using perlite in order to create run-off that can be tested for the ppm (parts per million) so you can see exactly how much your plants are taking up, how much is being wasted, or if your plants can take more. Understanding how much food your plants are eating play a vital part in deciding how often you should feed them. The medium can also largely affect this process. The ability to check your run-off is awesome for those set up for it but often outdoor growers are forced to forgo this luxury which is why a lot of nutrient companies will often have a feeding chart that comes standard with their fertilizers or can otherwise be found on their website in order to save you the hassle (for example: here). These will often show you a week-to-week system with feeding rates that will give you the optimal results. This will get a bit more tricky if you are using fertilizers from across separate brands so we would recommend finding one you like and sticking with only their line. If you have a hard time committing to one it is possible to use online resources and forums to find schedules based on other people’s tests of products from across brands but these can be unreliable and often lead to unexpected results.
