How do I separate my dahlia tubers?
I have growing my dahlias for about 4 years now and never separated the tubers before other than the ones that fell off on their own. This year I want to divide them. I have placed them in dirt and waiting for the eyes to appear. Once they appear how to I divide them? What tool is good to do this?
Also, after dividing them, should I treat the cuts with something like sulfur? Next, after dividing them, is it safe to put them back into the ground with their new cuts exposed to the soil. Or should I wait until they scab over?
Let me know ASAP
