Re: CULT:Watering Twice a Day

Hi

We never overhead water our irises. I'd be too worried about rot. We use
T-tape, thin black plastic tubing with little slits every 8 or 12 inches. It
is also a far more ecconomical way to use water.

We discourage customers from planting TBs in Jan-Feb (our really hot, dry
months) as most can't resist over watering  and causing rot. In our climate
of mild winters and very hot summers, we recommend transplanting immed after
flowering (Nov-early Dec) or in  autumn March to May, depending on when the
season breaks. We do our own transplanting May - July with very little
interference to blooming in Oct.

With summer transplanting, if I do it, I'd water a little every 2-3 days for
a couple of weeks (until growth starts), then no more than once a week. This
way I lose very few.

BTW  isn't it amazing how plants know the difference between irrrigation and
real rain. They always respond so much better to rain, especially in a low
rainfall climate.
