One dahlia looking a bit bedraggled...
I have around 45 dahlias this year. 44 of them look normal, but one is looking decidedly bedraggled. Hope it doesn't have Covid like I do at the moment! There are four sets of leaves: two look normal and are growing, two have curled and turned dark green. They haven't developed much compared with the others. I haven't fed them beyond a layer of compost on the top of the earth about four weeks ago. Any tips on what I should do?
Bumping this up in the hope that there's a dahlia expert who can advise.
Hope you feel better soon.
