- PH adjustment
- Amending soil
- Raised beds
A pelletized dolomitic lime that raises acidic soil pH while adding calcium and magnesium, so plants can use the fertilizer you apply. The low-dust pellets react faster than powder, and one 6.75 lb bag treats ~100 sq ft. The caveat: it only helps acidic soil, so soil-test first, since liming neutral or alkaline ground harms plants.
Pros
- Pelletized form spreads evenly and reacts faster than powdered lime without the dust and hazards of hydrated lime
- Raises acidic soil pH so plants can actually use the fertilizer you apply, and supplies calcium and magnesium
- One 6.75 lb bag treats about 100 sq ft, making it an inexpensive fix for sour soil
Cons
- Only for acidic soil, applying it where pH is already neutral or alkaline harms plants
- Works slowly, so it should ideally be applied a few months before planting
- Requires a soil test to dose correctly, or you risk over-liming

Frequently Asked Questions
- Should you add lime to your garden?
- Only if a soil test says the pH is too low. Applying lime where soil is already neutral or alkaline actively harms plants, so this is one amendment you should never add on assumption.
- Why pelletized lime instead of powdered?
- It spreads evenly and reacts faster without the dust of powdered lime, and it avoids the handling hazards of hydrated lime entirely. Coverage is about 100 sq ft per 6.75 lb bag.
- How long does lime take to work?
- Slowly — ideally apply a few months before planting so the pH has shifted by the time roots are in the ground. It also supplies calcium and magnesium as a side benefit of the dolomite.
