If you try recharge, just know most people use way too much of it. 1/2 tsp makes 1 gallon, you can treat 10 20 gallon pots out side, only needs a cup or so. Its best to add it when the pots are wet too. Outdoor i will feed the plants then add the recharge at the end. Indoor i feed the plants, next day i add about a cup to my 5 gallon pots. hope this helps
