Hallo. This is my first post, so I hope i’m doing it right! I grow quite a lot of dahlias, mainly for cutting, and I especially like the vivid coloured ones - reds, purples, oranges etc. I was very pleased to find a lovely red called Grenadier and last year I bought two rooted cuttings. Unfortunately, the stems were very floppy, even though the actual flower was lovely. I overwintered them, but this year, they have been just the same. So has anyone else had this problem? Is it just the variety, or have I used too much /too little fertiliser? I’m sure they held themselves much better when I first saw them at a trial at Wesley several years ago. Would be grateful for any thoughts.
Do you grow them in pots or in the ground?
If you can enrich the soil, that's usually better than using lots of additional liquid or granular feeds.
Failing that, perhaps it would be worth simply using a nice support early on for them
I live in west central Scotland - not where that photo is...
