Hi guys-
Wondering if anybody knows about the application of dolomite lime? I grow in soil and I never mess with PH since the meter I have I dont trust, and I could never afford a good one. Anyway, I had some pelltized lime I used to use but now I hear this Dolomite is better to use. I have some on the way that is 22.7% Calcium and 11.8 Mag powdered. I grow in mostly 3 1/2 gal pots with a few 5 gal pots as well. I'm wondering how much to use to give some sort of balance to the acidity without overdoing it..?
Any input is appreciated

I use a good handfull, probably 1/3 cup, per 5 gallon potting soil.

Unless you really go crazy it's hard to overdo it.
 
The lime raises ph and does not lower it. I did not know this and used the lime with water that was over 8 ph.

Had terrible grows till I figured it out. The ph drop tests are cheap and work fine. Figured out my water ph with the drops.

Stabilizing pH with Dolomite lime

The best way to stable PH is by adding 1 ounce of Dolomite Lime per 1 gallon of planting soil.

Dolomite Lime is available in garden nurseries. Buy the fine Dolomite powder (There may be several kinds of Dolomite like Rough, Medium, Fine)

Dolomite Lime has been a useful PH stabilizer for years, since it has a neutral PH of 7 when added to your soil it stabilizes your soil at PH 7.

Mix the dry soil medium and dolomite together really well, give the mix a good watering then after the water has had chance to settle and leech into the soil a bit give the mix a really good stir. Then water the soil/lime mix and give it another stir

Best plan is to mix fine dolomite lime into your mix before planting. Fine Dolomite will help stabilize your pH; however, if the ph becomes unstable or changes, you can then use Hydrated Dolomite Lime. Add some of the hydrated lime to luke warm water and give it a good stir then water your plants with it. Give the plants a good watering with this hydrated lime added and your PH should fall or rise back to 7

Other Benefits of Dolomite Lime

Dolomite lime is also high in two secondary nutes that can often be overlooked by fertilizers; dolomite is high in both (Mg) Magnesium and (Ca) Calcium.
