Need help picking?
Which dahlia?
You’re spoiled for choice with dahlias, with a multitude of different heights, forms and colours. For a bee-friendly garden, choose single dahlias with accessible centres, or too-good-to-be-true pompom and ball dahlias for the cutting garden. Most types will keep flowering right up to the first frosts and will produce more blooms the more you cut.
Planting schemes and partners
Dahlias are often grown in a bed with several colour themed varieties together, but they also make a lovely addition to a cottage garden scheme or a mixed border, whether you use tall varieties as accent plants or weave drifts of them throughout your beds. More compact dahlia types, such as Dahlegria, make a striking feature in patio pots and can even be used in hanging baskets.
Growing tips
Dahlias are sun loving plants which need regular watering. For the best blooms and growth, feed them every couple of weeks throughout spring and summer, with a high potassium feed such as tomato food. Taller varieties may need staking - tie them gently to a garden cane or support them against a fence. To make your dahlias bloom year after year, dig up the tubers once they’ve finished flowering and store them in a cool, dry place over winter. Then plant them again in spring and enjoy them all over again.
Dahlia FAQs
When is the best time to plant dahlias in the UK?
The best time to plant your dahlias is after the last frost has passed, usually from mid to late spring, around May or June.
Where should I plant my dahlias?
Dahlias need a position with full sun and well-drained soil. Choose a spot where they’ll get at least 6-8 hours of sunlight per day in a border, bed or pots.
How do I plant dahlias?
To plant a dahlia tuber, make a hole about 20cm deep and slightly wider than the tuber. Put the tuber in the centre of the hole with the growing part facing upwards and the bulbous roots downwards. Fill in with soil, leaving the growing part peeking out, and space your tubers at least 45cm apart if you’re planting more than one.
How often should I water my dahlias?
Give your dahlias a good watering straight after planting, then water them regularly throughout the season, taking care that they don’t get waterlogged.
Do dahlias need fertiliser?
It’s important to feed your dahlias to get the best flowers. Use a feed that’s high in potassium (potash) such as tomato feed, and apply it every 4-6 weeks throughout the growing season.
How do I support my dahlia plants?
Most dahlia varieties have tall stems and large flower heads, so they’ll need support to prevent them breaking. You can do this by tying them to plant sticks or bamboo canes, or using grow cages around the plants.
When do dahlias bloom?
Dahlias are long flowering plants, usually blooming from midsummer right through to the first frost in autumn.
Should I deadhead my dahlias?
If you remove the faded flowers, the plant will be encouraged to produce more. You can do this by cutting the stem just above a set of leaves or buds. Even better, don’t wait for them to die - cut them when they’re in full bloom and use them to brighten up your home.
What do I do with dahlias in winter?
If you live in a warmer part of the UK, you can probably get away with giving your dahlias a thick layer of mulch in the autumn, to keep their roots from freezing. Otherwise, you can keep them safe from the cold by storing them over winter. To do this, dig up the tubers after the first frost, cutting back the foliage and let them dry for a few days. Then store your tubers in a cool, dry place over winter and replant them in spring. Looking for inspiration? Take a look at Jenny’s dahlia garden!
Plants arrived in great condition and very promptly. Well established - much better than the ones I got at my local garden centre.
