Q&A for How to Add Potassium to an Organic Garden

Basically, there are restrictions on the types of chemicals, the types of insecticides, and the types of fertilizers that a certified organic farm can use. Sometimes they are more earth conscious, so for example, certain pesticides would not be allowed on a certified organic farm. Usually, it's more natural, but not always. There are many exceptions and many instances where certified organic farms are less sustainable. It's not necessarily always true that certified organic farms are safer or more natural. It depends 100% on the ethics of the grower.

It depends on what you're growing. If you want to grow organically, you will add quality compost and a little bit of nitrogen fertilizer. You don't need to add other things. If you're looking for a fertilizer that does everything, you want a balanced fertilizer. If you look at the front of the bag of fertilizer, there are three letters, NPK, representing nitrogen, phosphorus, and potassium, along with their quantities, for example, 10-10-10 or 20-20-20. This is much more potent and a lot easier to over-apply. You have to be very careful. An organic fertilizer might look like 3-3-3 or 3-5-2. It's generally weaker and you have to generally apply more of it. What you apply is based on the requirements of your plants. Some plants want more fertilizer than others.
