This year some of my Dahlia planted from seed while other plants did not. Is it worthwhile to overwinter the tubers of the plants that did not produce flowers.
Well, if you have the time and the space.......
Most of mine flowered and I just plan to overwinter the ones I liked best. In my view they had their chance this year so if didn't flower into the bin they go
I find it REALLY difficult to throw anything away, even if I don't like it or it's half dead. Probably the wrong person to give advice on this subject!
Posy - I've been quite good this year on the ruthless front (not like me either) even thrown some named Dahlias that I didn't like for one reason or another (too big in the main). Although that may have been impatience to get my spring bulbs into their containers.
Mandor - how did your Bishops Children turn out?. I have some of the named Bishops: Oxford, Canterbury, Auckland, Llandaff and to be honest some of the Children I grew from a seed packet resembled these named ones quite well so looking forward to seeing if they have formed decent tubers and will overwinter ok.
