Dahlia tuber clumps

Posted by trustmissy 5MidMich (My Page) on

What determines how many new tubers are produced by a dahlia? I dug up my tubers yesterday and one of the plants has at least 30 large new tubers on it, while others have small fingerlike tubers and one only has the mother tuber.

Fate. The one with only the Mother tuber will be the one you liked most. The one with 30 offspring will be one you never wanted to see again.

Some varieties seem to be good, consistent reproducers with reliable storage qualities. Others are fickle and temperamental and vary year to year. That's my take.

Genetics is the determining factor. Some varieties are enthusiastic tuber producers and others much less so. Having said that, there are differences from clump to clump. One clump of a variety may have 10 tubers and another only 2 or 3. Varieties that make lots of tubers survive longer in commerce.

That is true enough Teddahlia. I just dug two of the same variety yesterday growing 20" apart. One clump had about 3 usable tubers and the other had 3x that number. Pretty close to identical conditions/treatment through the season. Some are just so hearty and good reproducers, whether you want them to be or not.

As much as I dislike digging at this time of year, it is a bit intriguing to see how the plants have done as far as root formation goes. At least, that's what I keep telling myself...

I still have more to dig. Some were so deep. I can't see eyes and hate to store all these tubers. Someone also said to spray them with Neem Oil?????
