Gladiolus cultivation

Hi Dell,
The most important thing about growing glads from seed is that they
require a ten degree differential between day and night temperatures. The
second thing is to learn which are summer and
which are winter growers. Winter growers do not do well here in Gresham,
Oregon with our heavy rains which total about 48 inches annually.
