Management of environment (lower humidity, higher temps) and fungicides can
control this.

Browning at Babiana leaf tips is an indication of a wintertime Botrytis

Dear Bob,

You seem to have hit the nail on the head (Carpenter -wise) with
your plumbing suggestions. Bad roots usually means bad leaf tips. Too

far

from the water source to ‘prime' the ‘pump' and ‘pipes’ all the way to

the

leaf tips.

And like you I have salt build up and pH changes due to hard
water. Some plants need frequent ‘flushing’. Usually a summer outdoors
gives them enough rain water flushing to last for a long time, but watch
out. Pots get crusted with calcium deposits and need heavy cleaning and
brushing before reuse.

I’ll keep this hand plumbing vocabulary in mind for the future.
Best Jim

Browning at the leaf tips is the first sign that what Jerry Morris

(dwarf conifers) calls “the pump” is not working properly. The area
farthest away from the roots, the leaf tips, is the first to show signs

inadequate hydration.

One of the most startling things I read there was the necessity of

flushing the potting mix (with water) from time to time to avoid salt
build-up, and the effect salts have on root hydraulic conductivity.
