 geranium leaf burnThis happened about 2-3 days after rooted cuttings were transplanted in a dry medium. PH was 6.2 and E.C of the leach was at 1.2 mmhos. It took about an hour before water was applied to the growing medium. Rooted cuttings come with lot of root hair which are involved with the absorption of water and nutrients. Exposed to dry medium root hair are damaged which caused these leave edges to dry out. No pesticides were applies on these cuttings. So make sure that a wetted growing medium is used.
