Ever wonder what happens to the dahlias after frost?
We start by cutting back all the foliage. And I actually cut back the plants last week BEFORE the frost. Not necessary, but definitely easier to work with living tissue than cold mushy stems.
If you have just a few plants, you may want to leave them blooming right until frost takes them. But with 700 dahlias in the field, I plan around the weather and field crew availability.
So that meant we cut them on a dry sunny day last week when I had extra hands on deck.
You can dig the tubers immediately, or leave them in the ground a couple of weeks to let the eyes form up a bit. If the weather is nice, I like to give mine at least a week in the ground. That gives me time to remove all the stakes and psyche myself up for the actual digging!
Come back tomorrow for the tools and tricks in digging.
