How often to use Espoma Sulfur?

Posted by sterph116 (My Page) on

About a month ago, I used Espoma Garden Sulfur on my 4 Nikko hydrangeas, and they have now bloomed a gorgeous blue color. My question is, how often should I apply the sulfur? Is it something I should do just once a year, or more often? Thanks for any help!

RE: How often to use Espoma Sulfur?

Once you attain the desired hue of blue, you need to determine what PH Level your soil currently has and you will need to re-apply your ammendments when new measurements show that the PH Level has become more alkaline. In between checks, you can probably add a smidgen (a tbsp or so) or once every week to 4 weeks (your choice). The "proper" amount is variable and is a function of many things, such as your geographic location, soil type (sandy, normal, clay), local weather (rainy, ...), etc. Increase the frequency and/or amount so it will yield the proper blue hues and maintain your soil Ph at the same level.
