Title: gladiolus winter or summer growth: when to water again?
Post by: Véronique Macrelle on October 12, 2018, 07:07:41 AM: I sowed Gladiolus from the seeds exchange in January and got some seedlings. who rested at the beginning of the summer.

G. cunonius
G. watermeyi (I got a single seedling, really tiny ..)
G carneus,
G. splendens
G. meliusculus
G. atroviolaceus

it is not always easy to know if their growth is winter or summer. should I water them to make them leave?
bulbils were very small for some species, I would not want them to dry out.

G. carneus makes me shoot 3 (out of 20) after watering .. the others, nothing.

then I water or I do not water?
are they really winter growing?

so G cunionus and splendens must stay dry until about April?

my other summer Gladiolus are still in leaves, so I worry about them

phew, I finally have 1 G. meliusculus that appears

Post by: Véronique Macrelle on November 07, 2018, 10:54:04 AM: according to pacific bulb society, Gladiolus cunonius is part of the summer-growing gladiolus. off, my spring sowings are vigorously restarted, and are all present.
Dave's garden seems to say that it blooms in the spring, which suggests that it is rather wintry. or does it retain its austral rhythm or is there an error in the name of the seed?

strange and beautiful flowering.
maybe I could hope for one in March 2020 ... the new shoots are vigorous compared to those of G. meliusculus (like a hair).

what is the minimum temperature in your greenhouse in winter?
