yea you can top dress the soil with the dolomite lime.may not be the best but will get you by,just make sure you mix it in as best as you can.i would add only 2 tablespoons at the most.make sure you remix the top soil whenever you can
mscaboo Reviewed by mscaboo on . adding lime to soil w/ plants already in.(help needed) ok so Im using sunshine no.4 soil less mix(no nutrients in soil) and i tested my runoff after the first week of veg and the ph is 5.7-6.0...I would like it 6.3-6.6 but i didnt mix any dolomite lime into my soil like i probably should have...So what should I do to raise the ph? i know giving it higher ph'd water is a quick fix, but that doesnt seem the way to go, can i put some lime just at the top of soil?maybe 2 inches deep or so in certain parts and just continue to water? any advice would Rating: 5
