Dahlias growing slowly
Anyone else here having slow growing dahlias? I began gardening a few months ago and picked up some decorative dahlia tubers in May at a big box store. They were sprouting up quite quickly when I first planted them but stalled in growth after I pinched back. They seem to be growing faster now that I've put them in the ground for the past month...but they're still quite small. It's the end of July and my largest plants are still only 2 feet tall! The smallest ones only have about 4-6 leaves (new growths sprouted out from the eyes this month). I fertilized with all purpose fertilizer (12-4-8) two weeks ago , but it doesn't seem to have much response. Will I be able to enjoy any blooms this year? I live in Ontario.
