We have blossom end rot problem which is apparently a calcium deficiency. We have some builder's lime which I am told is calcium hydroxide and would like to use that as the calcium source. We can't afford to buy anything else so we need to use that. We have a few questions: 1. do we have to do anything to the lime to make the calcium available, to 'unlock it' so to speak? 2. what amount do we need to apply to correct blossom end rot? 3. do we have to be concerned about PH change and if so how do we compensate for it?
The goal is to not have it change the ph and that the calcium would be available for the plants right away. Thanks.
