Hello everyone,
does anyone have a rough estimate on the speed of growth of gladiolus byzantinus? I have a plant show in a weeks time, and my plants are at the expanding flowerspike stage, with individual forming buds viisible, but still shut and no sign of colouring...i cannot remember how fast they grew last year, and am wondering if i should bring them into a heated veranda or similar to speed them up a bit so they can make it for next friday?
i can attatch a picture of them tomorrow if that helps...
