Old House Gardens dahlias not growing
I've planted almost 40 tubers this year, most of them started early and some of them are 1-2 feet tall at this point.
I got a handful of bulbs from Old House Gardens which offers heirloom vintage dahlias. Only one or two out of the 6 I purchased have actually budded and are growing stalks. One of them had an eye with the start of a stem but it's died back since I planted it in the ground. But everything else other than one more (Fuzzy Wuzzy from Swan's) is growing fine.
Has anyone had this happen with OHG tubers specifically? I am going to email them but wanted to just ask first--also wondered if maybe heirloom might just take longer--but these things aren't even growing roots. The tubers aren't softening either. They are just acting like they are completely dormant and sleeping. They are in the same bed as other tubers, getting full sun probably about 10hours a day.
Funny how some of the dahlias really just leap out of sleep and go gangbusters from day 1, others leap up then kind of grow more slowly and then you have these which aren't doing anything!
