🌱 Garden & Lawn Application
| Application Area | Rate | Frequency | Notes |
|---|---|---|---|
| Garden Beds - Sandy Soil | 2-4 lbs/100 sq ft | Test after 6 months | Light soils need less |
| Garden Beds - Clay Soil | 8-10 lbs/100 sq ft | Test after 6 months | Heavy soils need more |
| Lawns | Match annual fertilizer | Once in winter | Balances fertilizer acidity |
| New Gardens | 5-10 lbs/100 sq ft | 3-4 weeks before planting | Test soil first |
📊 pH Adjustment Guide
| Current pH | Target pH | Dolomite per 100 sq ft | Time to Effect |
|---|---|---|---|
| 4.0 | 6.5-6.8 | 12 lbs | 3-6 months |
| 4.5 | 6.5-6.8 | 10 lbs | 3-6 months |
| 5.0 | 6.5-6.8 | 7 lbs | 2-4 months |

| 6.0 | 6.5-6.8 | 2-3 lbs | 1-2 months |
⚠️ Important Application Tips
- Always test soil pH before applying—don't guess!
- For applications over 50 lbs per 1,000 sq ft, split into two treatments 6 months apart
- Avoid applying immediately before planting seeds
- Water thoroughly after application to begin activation

FREQUENTLY ASKED QUESTIONS
Q What is dolomite lime and how does it differ from regular lime?
Dolomite lime is a natural limestone containing both calcium carbonate and magnesium carbonate. The key differences from regular (calcitic) lime are:
- Dual nutrients: Contains 22.7% calcium AND 11.8% magnesium (regular lime is mostly calcium)
- Slower acting: Takes 2-6 months for full effect vs. 1-3 months for calcitic lime
- Better for Mg-deficient soils: Ideal when soil tests show low magnesium
Choose dolomite when you need both calcium and magnesium, or when soil tests show magnesium deficiency along with low pH.
Q When and how should I apply dolomite lime?
Best timing:
- Fall application: Ideal for spring planting—gives lime time to react
- 3-4 weeks before planting: Minimum time needed for initial pH change
- Winter for lawns: Balances acidity from fertilizer applications
Application method:
- Test soil pH first—don't guess!
- Calculate amount needed based on current and target pH
- Spread evenly using broadcast spreader or by hand
- Work into top 6-8 inches of soil
- Water thoroughly to activate
- Retest pH after 3-6 months
Pro tip: Split large applications (over 50 lbs/1000 sq ft) into two treatments 6 months apart.
Q Which plants benefit most from dolomite lime?
Plants that love dolomite lime (pH 6.5-7.0):
- Vegetables: Brassicas (cabbage, broccoli), beets, asparagus, spinach
- Fruits: Apple trees, cherry trees, pear trees
- Lawns: Most turfgrasses prefer pH 6.0-7.0
- Flowers: Clematis, delphiniums, sweet peas
Plants to AVOID liming (prefer acidic soil):
- Blueberries, azaleas, rhododendrons (pH 4.5-5.5)
- Potatoes (can develop scab in alkaline soil)
- Pine trees, oak trees
- Hydrangeas (for blue flowers)
Q Can I use dolomite lime in my compost pile?
Yes! Dolomite lime is excellent for composting. It:
- Speeds decomposition by creating optimal pH for microbes
- Reduces odors from acidic breakdown products
- Adds calcium and magnesium to finished compost
- Helps neutralize manure-heavy piles
Application: Sprinkle 1-2 cups per cubic foot between layers as you build your pile.
