I have a good sized, healthy dahlia plant just given to me. It is from this years propogation, so I don't think it has corms yet. Could I take cuttings from it now? Or do I have to wait until it has developed corms before taking cuttings next year?
You may want to remove stems or nip them back to promote bushiness; which would be an opportunity to take a cutting or two. Dahlias come easily from stem cuttings as long as they are not hollow - so young stems, or close to a (non flowering) growing tip.
I cover the pot of cuttings with a clear plastic bag supported with a few sticks to keep it off the foliage and secured around the pot with an elastic band, then as others have said put it somewhere sheltered and out of direct sun and aside from making sure it doesn’t dry out, you can just leave it for a few weeks. Once you see a lot of roots at the bottom of the pot you can pot them on.
chances are they will only make small tubers this year but it’s a start and it’s still free plants. 👍🏻
Many thanks for your replies Perki & Bilje. I guess it would be better to wait until next year, when I have some tubers on the plant to work from.
Hello again folks
I have now taken three stem cuttings from my dahlia, which(so far), are looking very promising. Looks like it may be a success!!
