So I’ve requested Claus to level us how he creates his container gardens. The general interview and fabulous views of his yard are on this video on YouTube, nonetheless I’ve summarised the small print correct proper right here.
Do dahlias develop efficiently in pots?
They undoubtedly do. Claus grows most of his dahlias in pots and the current is fabulous. He grows a variety of types, sizes and hues.
Dahlia grower Sarah Raven signifies that it is important select the shorter dahlias for pots on account of they’re so much a lot much less liable to flop. Nonetheless Claus places a spherical help onto the pot on the time of planting so he is ready to develop the larger dahlias in pots, too.
In exact reality, most vegetation will develop in pots, together with bushes. (See correct proper right here for normal solutions on rising vegetation successfully in pots.)
Suggestions on strategies to plant dahlias in pots
Claus begins in April, which is early spring in Denmark. He first places the dahlia tubers into commonplace plastic pots. The pots typically are often not fairly so much bigger than the dahlia tubers, in order that they match fairly snugly. He then presents solely a skinny layer of soil on prime. ‘I put merely 1cm of soil on prime of the vegetation,’ he says. ‘They appear to begin to develop sooner.’
He retains these pots of dahlias in a frost-free greenhouse.
After spherical 5 weeks, the early foliage of the dahlias has emerged. So he vegetation them into their everlasting containers. As rapidly as as quickly as additional, he vegetation fairly snugly. ‘I typically put three tubers into an enormous pot,’ he says. In smaller pots, he’ll merely put one tuber.

He vegetation annuals in pots, equal to cleomes, together with shrubs like ninebark and philadelphus. Any plant will develop in a pot, on the very least for just a few years.
Repeat the types of plant all through the grouping
Claus believes that repetition is essential when planning every a border or a grouping of pots. You may uncover the equal lilies, begonias and dahlias repeated alongside the pot grouping.
The chartreuse inexperienced foliage of Aralia cordata ‘Picture voltaic King’,Phsyocarpus ‘Nugget’ and Philadelphus ‘Aureus’, and the acute orange of the begonia add zing to this grouping of pots. And also you may even see the lilies, dahlias and utterly completely different vegetation are repeated at intervals.
His subsequent tip for making a dramatic coloration grouping – plant some pots with contrasting lime inexperienced or ‘chartreuse’ foliage. It gadgets off the darkish leaves and wealthy colors of the dahlia flowers. His favourites embody Aralia cordata ‘Picture voltaic King’, Physocarpus ‘Nugget’ and Philadelphus ‘Aureus’.
The splashes of citrus inexperienced and orange actually make this current of pots work. The orange begonia is Begonia bertinii.
The philadelphus and physocarpus can develop fairly tall, nonetheless Claus cuts them correct all the best way all the way down to 20-25cms in spring. New, smart inexperienced foliage springs as soon as extra. You don’t get the flowers should you scale back them as soon as extra in spring. Nonetheless Claus likes these vegetation for his or her foliage not their flowers.
One completely different methodology of along with that splash of citrus smart is to incorporate a flower like orange begonias to the group.
Add prime to the grouping of pots
The following tip is so as in order so as to add distinction with prime. ‘Spikes are vital’ all through the pot current, explains Claus. Plant some taller, upright vegetation in your grouping with the dahlias.
Loads of the vegetation in Claus’s pots are ones we regularly ponder as border vegetation. For instance, he has Cleome Violet Queen, Buddleias Purple, Angelica Gigas and Verbena bonariensis.
I haven’t seen Cleome ‘Violet Queen’ grown in pots before, nonetheless it seems to be good in Claus’s yard.
He furthermore has lilies, which develop notably efficiently in pots. Many individuals protect their lilies in pots and wedge them into the border in time for a implausible current, then whisk them out as soon as they’re over.

Distinction flower sizes

For instance, verbena bonariensis, which is tall and ethereal, with tiny flower heads. In spring, he cuts the verbena bonariensis vegetation as soon as extra to about 10cm, which makes them additional bushy and fewer tall after they flower in summer season season.
What to do with dahlias in pots over winter
Claus takes the whole dahlia tubers out of his pots for the winter. He cleans the soil off and wraps them in newspaper. ‘Then retailer them someplace the place the temperature doesn’t go beneath spherical 5C,’ he says. ‘It’s vital that they don’t freeze.’

So don’t depart dead-heading to a once-a-week-job all through the yard.
I reap the advantages of Darlac snips, which have been truly useful by Frances Moskovits.
