Hello all! This is my 3rd year growing dahlias, and I usually have around 10+ tall and 30+ short. I had 20 tall to start indoors this year, and I've just moved them out earlier this week to harden and grow stronger before I will transplant to my garden at the end of this month. (Zone 5b-6a).
Though I'm using the same lighting system as always, my stems are looking a bit puny this year. I did try to start them a little earlier (early March as opposed to April, last year), and I divided the tubers more than I have in the past.
This stem has just shriveled up in one spot. It does not seem to be cut anywhere. It just collapsed. I don't think there is any rot from initial inspection. Has anyone seen this before? Just curious if it is some kind of pest that I should be looking out for. I'm starting a new ("OMG") dahlia this year and it's pricey! I don't want to lose it. :D
