Oh Wow that is a tough one to answer. Varies from cultivar to cultivar. If you get six really good ones from a clump should be a good number just from my experience. Steve in Stevens County.

Dahlias vary greatly in tuber production. Varieties like Chilsons Pride, Mingus Toni, Alamode, can have 10 or 15 from a large healthy plant. More commonly the average is about 5. Phil Mingus who has grown them for over 60 years figures on 5 tubers per plant. Of course there are the few varieties that make anywhere from one to two or three. Others make five or six but most of them rot in storage.

In my storing of tubers i let the tuber tell me when I take them out of storage. If they are very lg. I wiggle them apart and try to keep eye's on each seperate clump of tubers, usually I get 2 or 3 from each clump, because I like full bushie plants w/ lots of blooms so I try not to make the clumps of tubers to small. I don't usually seperate them before storage unless they naturally seperate when I dig them up. it varies with each plant. hope this helps.mc1720161318099ec rosa. abbystractkat@cox.net
