So I have some plants going gorilla style in the woords. The method I transplanted the plants in the woods may seem a little crude to some of you. I dug up a hole in the ground and filled it with my own mix. The size of the hole is about 18" by 12" (45 cm by 30 cm). I filled it with a mix that is roughly 70% peat, 15% worm castings, 15% vermiculite, 2% dolomite lime, 1% polymer water crystals. My concern is this: The hole isn't very big. It's perhaps 10 liters in size. I tested the surrounding soil's pH, it's 5. The nutrient test restults are as follows: very low nitrogen, high phosphorus, and very low potassium. I want to raise the pH of the soil that is surrounding my dug up and replaced soil. I figure that in about 2 months the roots will outgrow the hole I dug up and soil I planted for them. Coincidentally, the plants will be in flower at this time. Since the native soil has high phosphorus and low N and K, I woud like to take advantage of this soil for flower, but my obstacle is the low pH. What is a good solution to raising the soil pH?
You can use powdered dolomite lime or wood ashes to raise the pH. Sprinkle it on top or dig it in a bit. 1 ounce per gallon is rule of thumb.
Eggshells also work as lime as well. I know Corto already knows that, im just telling anyone else who doesnt already know that.
Thanks guys for your help. But it just blows my mind that sprinkling some dolomite lime on top of the soil will affect the pH of soil that is 3 feet below where the lime is sprinkled.
