Recent development of yellow brown rising from soil level

Post by David48 »

A number of my plants growing in Brazil have recently developed a problem, producing a yellow brown discoloration from soil level rising up the base.

The plants grow in the open sun for much of the day, that has not scorched them previously, but recently she has sprayed the plants with a fertiliser, on the advice of the seller, and I wonder if this is a scorch resulting from spraying fertiliser onto the plants instead of watering in.

Some of them scorched, some perhaps only corking, but I'd grab the worst offenders and have a look at the roots.
