I just tested the soil in my garden and the ph was fun the nitrogen was very low which I know is an easy fix but the potash and phosphorus were both very high and i'm not sure what to do about them? I have already had plants planted in the garden for over a month and they just aren't growing as quickly as my plants usually grow which is what made me go to test the soil in the first place . I know I should have tested it before I planted the plants but I just bought a house and I've had a lot going on and it just happened this way anyone know how I can fix it ?
