How to grow Dahlias in pots

It’s late summer here in Denmark and soon the Autumn will arrive. The dahlias are still ok, but they were looking greater some weeks ago. Now they are a bit damaged by rain and wind.
Therefore I will show you a video I have produced about six weeks ago for Alexandra from The Middlesized Garden: / themiddlesizedgardencouk I’m almost sure, that you know this great channel. If not, I will suggest you to take a look.
The video is from 7th August and I think the Dahlias were looking great. I’m talking about several plants (see the list above) and I’m also showing how we plant the dahlia tubers in pots in the spring,
Aralia cordata 'Sun King'
Philadelphus caucasicus 'Aureus'
Physocarpus opulifolius 'Nugget'
Lobelia 'Hadspen Purple'
Begonia bertinii
Cleome hassleriana 'Violet Queen'
Buddleia 'Nanho Purple'
Verbena bonariensis
Lilium 'Purple Marble'
Angelica gigas
’Berner Oberland’
’Bishop of Oxford’
’Blue Bayou’
’American Dawn’
‘Franz Kafka’
‘Totally Tangerine’
‘Purple Fox’
‘Lilac Time’
‘David Howard’

My name is Claus Dalby, and I live in Risskov on the outskirts of Aarhus in Denmark. To date, I have written about 30 books on flowers and gardens in Danish, and my garden has been featured on many TV shows. In March 2022 my first book in English will be available. I consider my home (built in1908), and its garden with its neighboring wood, as my sanctuary. When I started gardening in 1996, there was just a large lawn covering approximately 1 acre (4,000 square meters), but today the grass is long gone - replaced by 15 hedged rooms with varying colors and moods. Additionally, one of my great passions is growing in pots, arranged to create spectacular container gardens, which I will share quite a bit about on this channel. Decor and creating moods have always interested me - both outside and inside - and I love to use the flowers from my garden for bouquets and to inspire other crafts that create a sense of hygge.

I’ve been waiting for this video, just so delightful to hear your Hello Hello ❤️

[@RuthieP67]

Another really useful video thankyou Claus (& thankyou To Alexandra from ‘The Middle Sized Garden’), it’s lovely to see how you create each particular type of display, especially the colour range, so giving us info on the dahlia cultivars & some of the foliage, in this case the chartreuse & lime plus the dark purple Angelica gigas - gorgeous! . I also have your latest wonderful book ‘Containers in the Garden’, which I have read from cover to cover & spent a long time studying the pictures, too. I mark the sections I know I’m going to need again with removable tabbed labels written in pencil 😊 . Thanks a million as always! 👏🏻 Ruthie x

[@manannan62]

Lovely video! Could you please talk a bit more about feeding regimen for the dahlias in pots. Thanks!

[@MG-mp8rw]

Gorgeous, gorgeous, gorgeous! It’s hard to believe that all that beautiful garden is really in containers. Thanks for sharing!

[@lauramarti7548]

You have inspired me to plant my dahlias in pots next spring. I struggled greatly digging them from the ground this fall.

[@marietownsend8396]

The sunflowers in the vase are an enviable specimen. Thank you for the video,

[@heatherw.2751]

I live in US zone 8A, coastal NC. I planted my first dahlia this summer. They are just magnificent flowers but I've always shied away from them. The variety I grew did spectacularly well with really no effort! I'm going to leave mine mulched up in the ground as an experiment over winter. Hopefully they won't get too cold or too wet! Claus, you are an inspiration!!

[@iselalopez4553]

Thank you for sharing your method with dalias. You encouraged me to try them this coming summer.

Your dahlias are so beautiful 😍. I love Dahlias. I have twelve I didn’t plant this year so I put them in my garden refrigerator. I hope they will grow next year. I was so busy planting so many things, I forgot to plant my dahlias. I’m in zone 9b Northern California. We have warm weather. I enjoy your videos and thank you for your knowledge. Blessings to you and your family 🙏🏾

[@wendychandler8304]

Thank you Claus. I have contacted several dahlia growers on YT, all with different methods. One is Dahliaholic (Geoff and Heather), and Sara Craven, who doesn't lift her plants. I hope to grow some this year, but without a greenhouse, I might lose them - then buy more!

[@ClausDalbyEnglish]

Good luck with finding your own way of growing dahlias - they are such wonderful plants.

Just lovely. Wow all in pots. Good job.

Your garden is so beautiful. I have been falling in love with Dahlia's and would like to try my hand at it. I live in Barcelona, Spain and only have a small balcony. However, I think after watching your video, I am going to try next year with one large pot.

Impressive garden! Do you replace the soil in the pots every year?

[@amybeckwith3332]

Wondering is there a source for your supports? I have a terrible time with staking. Thank you for sharing your wonderful gardens. Gardening in Maine.

[@marilufracassi1968]

Hello Claus. I enjoy your videos very much. Can you please elaborate on exposure with the different varieties of your flowers and shrubs? Especially the shrubbery? I have a very shaded back yard with dappled sun in the afternoon so I’m finding it hard to determine what I can add to my garden to make an impact.

[@user-ry8rt8io6p]

Hello. I saw your tobacco. I think you remembered me! But I wrote about smoking tobacco. And yours is decorative. This is different. There is smoking tobacco, tall with huge lime-colored leaves. It does not winter here in Russia. Annual. Its flowers are small and white. Very modest.

[@prajaktajoshi6280]

thanks

[@joanp105]

Do you only store the tubers in newspaper? What is your opinion on vermiculite? Do you divide your tubers in the fall before storing them, or in the Spring ( April) prior to potting them up for the first time? This was a lovely video to watch and I am sending it to many of my Dahlia growing friends.

[@BloominIvy]

I am about to do what you just asked. I have done a lot of research, and I will put mine in dampened vermiculite wrapped in burlap and put into crates with holes, you DO have to check on them in case the vermiculite needs re-dampening (so they don't shrivel). I hear division is easier in the spring because you can see the eyes much better. I would recommend pre-washing them before you store. Good luck!

[@ols641]

I will definitely put more plants in pots.

[@laelhouse]

it's nice it's nice 👍 👍👍

[@ClausDalbyEnglish]

Mange tak til dig for at kigge med.

[@KatherineTheGr8t]

I was looking for info on how to grow Dahlia's in pots but didn't get enough info to feel confident in buying the tubers and growing them. Do you cut the tubers into individuals or leave them as a clump, what soil mix - with or without fertilizer? When to water - what conditions am I looking for to know they need water? Are the pots covered ever - can I put them in the house or under an eave during the spring? When transplanted to larger pots, again what type of soil mix? When & with what to fertilize them with? What about fungus', bad bugs, or disease any tips? Perhaps you could do another video on everything you do for a single dahlia tuber cluster from overwintering to Summer blooms and when to dig up for another winter-over. I only have a patio so I will need to grow in pots but have full sun and am in zone 8 and know they will do well I just want to know what to do for a full year...as a new gardener I don't want to miss a step. The dahlia's have so many unique blooms -- they're gorgeous, as is your garden. Thank You Mr Dalby : D

[@EquusGdess]

I would also love a more in-depth look at fertilizing dahlias in pots.

[@jennyroberts1862]

How do you water all the pots, do you use a drip system?

[@MaraStephenson]

Hi Claus what you do about the powdery mildew? Can you please let me know what you do? I need your help, my Dahlias got mildew.

[@MG-mp8rw]

Hi Mara! Laura from Garden Answer has recommended Bonide Rose X, I did try it on my dahlias and it killed the mildew very quickly. I bought the diluted type, because I wanted the spray bottle, and then I bought the concentrate. I just refill the bottle. It has a strong smell of garlic, but it does work!

I was curious about this, too. It features prominently in the video so it is surprising that doesn't mention it. Not sure it is the same one, but if you view the listing for his new book on Amazon, he says one that looks very much like this one was a seedling (so not a named variety).
