Foliar spray is a weak solution application and usually require application every 2 weeks (10 days ??) if this going to be the only source of fertilizer or nutrients.



Once the calcium binds in the plant cell, it is locked. The calcium will not redistribute (recycle) within the plant to other parts that need it. The large green leaves that you referred to already have all the calcium they need. It's the new upper leaves & cigar leaf that needs the calcium to thicken and strengthen the leaf before becoming damaged & broken by wind while waiting on root uptake.


Dry forms of lime or gypsum still needs to be applied to the soil, but this will take several weeks to break down for the roots to take up the calcium.

So 3 or 4 applications by foliar spray will be needed.
