So in part-2, I updated you on the progress of the 7 dahlia cuttings which I ordered from the ‘National Dahlia Collection’ (

One month after arriving, 5 out of 7 of the dahlia cuttings were struggling, very slow growing, yellow leaves, spindly etc. Its now been 10 weeks since they arrived – so how are they doing?

OK. Not great, and quite disappointing really.
These 5 cuttings have been treated identically to the other 2 cuttings that did grow well, yet for some reason they have been plagued with problems. I’d read a lot about dahlia cuttings and many online websites and forums claim that dahlia cuttings grow better than dahlia tubers. This is simply not true! The tubers I planted at the same time are 3-4 times larger and much healthier than the cuttings.

All the cuttings seem to have Powdery Mildew which must have come from the National Dahlia Collection farm. None of my tubers have this, but Powdery Mildew spreads and the spores are already finding there way around the rest of my garden and infecting everything. I am very disappointed and would never buy dahlia cuttings again and therefore would probably not buy from the National Dahlia Collection again.

1. Alvas Doris (Small cactus)

As you can see from the leaves it has Powdery Mildrew (I keep trying to remove the affected leave to avoid the spores blowing around the garden). The plant is making slow progress, I just hope its producing tubers for next year.

4. Bergers Record (Medium Semi-Cactus)

This is one of the 2 dahlia cuttings that has done well, and as you can see it has started to produce flower buds, even though its not very tall.

6. Firebrand (Small Cactus)

Firebrand is 1 of 2 dahlia cuttings which has done well. It has already produced a gorgeous red/orange flower, which has now been deadheaded, and new buds have started to form 🙂

7. Mini Red (Miniature Cactus)

Mini red is like the other 5 weak dahlia cuttings, with yellow leaves and is slow growing.
