You may have heard that in order to keep your soil’s ph in balance, you need to add lime. And a neutral ph is especially important for Worm Farms. But which lime do you use?

There are actually four types of lime. The one that is most commonly used in worm bins and in gardens is the agricultural or garden lime. This is made from limestone or chalk.

Dolomite lime is almost the same as garden lime. But be careful, its not. The magnesium level is higher. Quicklime is highly caustic. This should never be applied directly to the soil. When this reacts with water, it creates slaked lime. Both quicklime and slaked lime do not meet organic standards.

Garden lime is the best solution for your acidic worm bins. It is not only fast acting, but also long lasting.
