Hello everyone, I grow lots of dahlias every year... they never went out of fashion in this garden! However I noticed today an interesting result of my efforts. In an effort to be reasonably scientific with the trial I never intended the results are as follows:-
1. Tubers lifted last autumn and stored in dry stable, potted up a few weeks ago. These have almost all thrived with very few losses
2. Tubers not lifted and left in the ground, mulched with old potting compost. These have all survived the coldest winter for years.
3. Tubers in large tubs, left in tubs and overwintered in GH, still in same compost with liquid feed added, all doing well.
4. New tubers, bought from GC in spring (carefully choosing largest/plumpest available), potted up ...significant failures/no-shows
The moral of this tale is that you should trust your own efforts and that the growers/GCs need to raise their game. For about 1/3 not to grow is unacceptable.
I would be interested to hear your dahlia stories this year.
