What nitrogen feed do you use on Chrysanths. Would ammonium sulphate be ok?
Ours tend to get a couple of doses of urea...
as long as it's not Sulphamate... :-X
It`s nearly 30 years since I last grew Chrysanths, but I used Chempak No. 3 until the first show of bud colour, then changed to Chempak No. 2 for buds and blooms. Always worked for me.
