My day job has been in high gear for the last two months and I've been taking a bit of a social media floral break. That doesn't mean I'm not still exploring the science and growing of beautiful flowers...
I found this fascinating and confirms what I've seriously been considering. Growing my foundation dahlia stock through cuttings instead of tubers.
As many of you know ( , ) or are still struggling with, dahlia tubers can take forever to wake up and get moving. A fully dormant tuber with clear eyes may still not wake up and sprout. Or may rot. Or the shoots might get mowed down, broken off, or burnt by hot soil and sun. Why many dahlia enthusiasts prefer sprouted, or "woken", tubers. That physiological change for a tuber to be vegetative growth mode takes time.
Cuttings, or rather plants started by vegetative cuttings, have their own risks. Creating your own requires certain conditions and indoor set ups. Then they need to adjust to the great outdoors. Dahlia cuttings can be easily broken, mowed down by pests or disease, or destroyed by sun/rain/wind.
Simply, not always a plant for the faint of heart.
Dahlia tuber clumps left in the ground in warm locations like ours (Sacramento zone 9b) or cooler areas with mulch (insulation) and the rain kept off, get up and running much faster than divided tubers. A combination of being in place (the ground) and ready to go, existing roots that aren't dried out, and not traumatized by dividing and storage.
Cuttings are plants. Just like any other plant you will buy from the nursery. Adjust it to the great outdoors, also known as "hardening off", and plant it in the right location, and you are off to the races. Have a number of the exact same plants and plant them together, they will grow consistently as a group together. Great for when you want consistent floral production and don't want plants shading each other unevenly.
This video is from Clara Joyce flowers looking at a Cafe Au Lait trial in Salinas, California. A great visual example of cutting grown, tuber clump, and divided tubers growing and blooming comparison.
This by no means, means I will stop growing, dividing, selling, and buying dahlia tubers. It just means I will most likely be starting earlier and indoors to then start my own cuttings from tubers so I plant plants, not tubers, instead. 🤔🤔🤔
