Each year, several times per year, fall or just spring and summer. This is for my Nikko blue hydrangea. I have seen great improvement so far, but I'm just unsure how often I should use it. If I apply now, in September, will it be retained through the winter?
The Hi-Yield Soil Sulfur can take 6 - 8 weeks to take full effect in the treated soil. So we recommend that you check the soil pH again after that time frame, and then reapply if needed to maintain the desired soil pH. I would check the soil pH again in the spring after snow has melted and the ground has thawed.
