April 26, 2024Q.Gladiola Identification
Hello, I have an orange speckled gladiolus that has been surviving on this vacant lot in the Historic district( goes back to the 1600s ) where I live in Fernandina Beach Florida. I wonder if there would be someone there, or someone you could recommend, to help me ID this one? Thanks in advance.

Certified ExpertA.You might find it by searching the internet for historic or heirloom gladiolus. Here is one source:

A trip to the library also may help. One search will probably lead to another.

Certified ExpertA.They take 70 to 100 days to grow and flower. Fertilizer is important as well as ample water. Are you concerned you won't have four to six weeks before cold weather to dig them up? You can wait till the first frost, but dig them within a couple days after a frost. These articles should help:

September 6, 2024Q.Failure Of Gladioli To Bloom
For the second year running, potted gladioli have failed to 'bloom'. Attributed it to drought last year, much, much rain, and also watered, this. Stored March-May in unused garage, both in packs, and loose, bought from 3 different sources. Growth immediate, right up to full height. Yet, of 110 planted, only six have formed 'corns?' - and these simply fail fully to open, and 'wither on the vine', without producing anywhere near proper blooms. Could it be the compost, which they inherit from (always wonderfully productive) tulips? Was never a problem when compost was changed, in between

Certified ExpertA.I wouldn't think it was the compost, but too much nitrogen can prevent blooms. Try adding some bone meal. It could be a disease or virus overwintered with them. Also make sure the containers drain well. Here is more:

Certified ExpertA.They usually last between 1 and 2 weeks. You can do what is called "succession planting", where you plant them every 2 weeks or so. That way you can guarantee blooms for awhile.
