Hello there,

Does anyone knows what's the dilution to foliar feed my cacti (T. pachanoi, T. peruvianus and L. williamsi) by night using Urea?

urea is 46% Nitrogen and I already diluted it to a pot with 'just' 10% Nitogen (1l of water contains 100g of Nitrogen). I'm thinking about a further dilution to 1% (1l of water containing 10g of Nitrogen), but is this still to much? Sould I go even further to 0,1%, 0,01%, etc of nitrogen?

For what I've read too much nitrogen can cause the cacti to split and, obviously, I don't want that to happen, hence my doubt.

Thanks in advance.
