How we prep our winter stored dahlias for field planting. I decided to divide my dahlias this spring instead of back in the fall. There is no right or wrong time to divide. I stored them in our temperature controlled garage over the winter in crates that were packed with peat moss, and experienced only losing one tiny clump/variety to rot, so storage was a success.
Once we take our dahlia clump out of the crates, we hose them off to clean them. We then start the dividing process and are looking for growth points or what we call the “eyes”, this is where the plant will start to produce its stem. You can see that some have already started to wake up and grow, which is great and makes it easier to see where to divide the tuber.
Dahlias are a great investment, as some tubers and rare varieties can be costly I was able to turn my 100 dahlia tubers from last year into over 700 tubers this year! Just took some elbow grease.
Once you have your tubers divided (you can also plant them back in the ground into the clump if you want and skip dividing if you don’t need more single plants) it’s time to get them in the ground and you should space them atleast 12” apart and dig them down 5-6”. Make sure there is no heavy rain on your forecast as tubers can rot if too much moisture, you also don’t want to water until you finally see green sprouting.
Then for the hardest part, waiting for the blooms! Dahlia season is typically August until the first fall frost, but boy are they worth it!
Thanks for reading and watching and hope you learned something new today 💕🌸
