How to Apply
-Established garden plants: ~1 lb per 2 ft of crown diameter, spread under the canopy and worked lightly into the surface
-Raised beds: 2–3 lbs per 100 sq ft, mixed lightly into the top layer of soil
-New plantings: 2–4 tbsp mixed into the backfill when planting shrubs or ornamentals
-Containers: 1–2 tbsp per gallon of potting mix before planting; top-dress monthly through the season
-Roses & flowers: ~1 lb per 2 ft of crown diameter in spring and at bud formation
-Bulbs: 1–2 tbsp per hole at planting
Step by step
1. Test your soil first, especially if you are managing pH for acid-loving plants.
2. For established shrubs, apply about 1 lb per 2 ft of crown diameter under the canopy.
3. For raised beds, apply 2–3 lbs per 100 sq ft and mix into the top layer of soil.
4. For new plantings, mix 2–4 tbsp into the backfill; for containers, mix 1–2 tbsp per gallon before planting.
5. Work lightly into the soil surface and water in after applying.
6. Apply in spring and again in fall for best results.
What not to do
Do not expect an instant pH change from the sulfur, do not exceed the recommended rate, and do not rely on it to add iron or manganese — it supports the acidic conditions in which those nutrients stay available.
