Taking Dahlia Cuttings 

true.., i am an addict gardener 😂😂😂

Love those trays as well. Don't see them in Canada either!

Do you know where we can locate them?

Tom Aaron Tom, Glad you found it helpful. I too grow Dahlias for the challenge of propagating them while most members of our Dahlia Society are heavily into showing. I have to admit that we also like them as cut flowers for the house too. I've recently got into self saved seeds too - far better germination than most commercially available seed and some very interesting varieties too. This year for the first time, I have saved some Dahlia seed too. Will maybe have a go at cross pollinating Dahlias to create 'new' varieties, but need to think about that one! Regards, Barry

How'd it go?

I think you will find that plants raised from seed will mostly not come true to the original variety - they will be a mixture of what ever varieties the pollenator visited ...

@@vc131a they were from a packet, not personally saved seeds. Yeah, I have no idea what I'll get. I also don't know why I said I would start them later next year when I will have tubers to replant 😆

Glad it was helpful!

B oI I love you and no Lo The new update

Hi Kathi, Pleased to hear that you found it useful - I started some of my tubers off on Monday 23rd, so the cycle has started all over again! Good luck with your experiment ... Barry

Greetings... panhandle idaho here. Did you have success over wintering your dahlia cuttings?

I check the cuttings every day, usually misting them daily and watering probably every other day but more frequently if required. Check by putting your finger in the rooting compost. HTH Barry

Hi Renee, Yes you should be picking flowers by mid August. Regards, Barry

Mostly I water the plants from below, so instead of watering from above, I put water in the tray and allow the plants to take up what they require - be careful though, don't over do it, a little and often is much better than a good soaking.

Hi, I don't usually keep the donor tubers as their ability to produce flowers is severely hampered by having donated so much of their growth. However, I do put them on the compost heep and they usually do produce a good show ... I've never really thought about root disturbance, so I think it will be quite an insignificant problem, given that the cuttings can be potted on several times.

Hello Ida, Thank you for your comments. In answer to your question, I don't know! I take cuttings from the tuber and then throw it away (actually I put it on the compost heap) because I think it has probably produced all of the possible shoots, so cannot produce more .... but I might be wrong. Several of the tubers I threw onto the compost heap this year produced some wonderful blooms, so either I threw them out too soon, or as you suggest, it might be worth planting the tuber after you have taken the cuttings. I suspect that you might be correct and that any growth will be quite weak, but worth looking at next year .. Regards, Barry

vc131a Thank you for you reply Barry! I have tried to start rooting some of my favourite dahlias now - some seem to like to live, and some of them turn yellow and/or limb.... I will just have to wait and see I suppose. I truly hope something will work, especially because a storm just flattened one of my dahlia patches in the garden. But can I please ask you another question? What excactly IS a pot tuber? Is it just a small tuber, planted in a pot instead of in the garden? and do you keep the growth of any shoots down? I am quite confused - some people say that they always keep 3 of each dahlia type as pot tubers at all times. Is the pot tuber then always in an active state? kept in soil over the winter? Sorry... as I said - I am confused - but also very eager to learn more. Thank you again Best from Ida

Ida Viemose Hello Ida, A lot of growers like to keep a stock of different varieties for the future, they don't actually want them for their flowers this year, but in case they want them in future years they create a 'pot tuber'. Some other growers keep several pot tubers in case they lose some of their main plants to disease etc.. to ensure that they have plants for future years. Pot tubers are also a good compact way of giving away plants to other growers, since they will shoot quite normally next spring. Our club has a tuber sale in January at which normal tubers and pot tubers are sold to members at an auction, so that they can acquire different varieties and to boost club funds. A pot tuber is created by planting a cutting in a plant pot and allowing it to grow. Instead of planting the dahlia out in open ground, it is kept in the pot for the whole summer. The plant will produce poorer top growth and flowers than one planted in open ground, but over the summer season the dahlia will produce a small compact tuber in the pot and the top growth will die down quite normally in the autumn. As the plants die back in the autumn, the top growth is cut down in the normal way. Some growers just leave the tubers in the plant pots and let them dry out, while other growers will take the tubers out of the plant pots and wash and clean them before storing them away in a frost free environment. When awoken in the spring, a tuber that has been grown in a plant pot will still produce good top growth from which cuttings may be taken and it will not take up so much room in the greenhouse. I hope those quick notes are helpful, I'll hopefully show more in a future video... when I get the time! Regards, Barry

vc131a Hi again Barry, Thank you very much for your answer - it really helped. I am going to use your advise in my dahlia garden - and cross my fingers that I have the competencies to do it right :-) I look forwards to any dahlia video you may make - I have studied the cutting video quite carefully :-) Best from Ida

would love some info on the large propigator

Yes, take the roots inside before your first frost date.

I generally start planting tubers ready for cuttings on February 14th - an easy date to remeber!

My apologies for taking so long to reply to your question, I don't check back regularly enough. Yes you can take cuttings in the autumn, the only problem is that you have to provide heat, light and moisture over the winter months in order for them to flourish. One problem I can foresee is that cuttings in the autumn will mostly have hollow stems that do not root very well ...... I intend to experiment this winter to test out the theory - I already have a large propagator for the heat, so need to buy some suitable lamps and a time clock. I think that so long as the plants have perhaps 16 hours of light, they should be OK. I guess I need to film the experiment too!

vc131a ... I appriciate your answer really much, as i can immagine your might be busy in your garden. well, i am looking forward to your "experiment video" and hopefully we can learn even more. I told some of my neighbours and all are really impressed how you did and we watched it all over again. I have not so much possibilitys with extra lamps and light during wintertime, so i have to wait until spring. Wish you best of luck, lots of health and HAPPY GARDENING ...

Hi Gordon, Thanks for your comments. Views vary re length of video and I did wonder myself if 38 mins was too long. The second part, 'Planting out dahlias' is even longer at 43 mins so more problems with attention span I guess....... A bit of a dilemma, with a third video in preparation. Cheers, Barry

vc131a Thanks for your reply Barry, if they like it I think they will go back to it Really enjoyed them ,look foward to the new one ,reguards gordon.
