Cushman - thanks for the advice. I think I have some dolomite on hand so I might try using that with water and putting it into the reservoir vs. buying all new ingredients. Is there any reason why you use the water vs. removing the cover and putting them into the dirt? Does it absorb faster? Since my peppers are all on one side, it would be easy to lift the cover and put the dolomite directly into the dirt.
No,no... Do not mix the dolomite with water and put in the reservoir. Dolomite is NOT water soluble (it will just sink to the bottom and be flushed out eventually)... it must be mixed into the soil and can take many weeks/months to become available to the plants. Please don't confuse dolomite
with fast acting hydrated lime
, which IS water soluble. The two are not interchangeable.
To treat existing BER, mix 1/4 cup of HYDRATED (or PICKLING) lime into 1 gallon of water and pour it into the reservoir. Do NOT pour it around the base of the plants, as it's still too concentrated to use directly on the plants. In the reservoir, it gets further diluted to a safe level.
Also, don't expect immediate results. It takes time for the calcium to be absorbed, and will only affect new flowers just forming fruits. Any existing tiny fruits won't benefit.
