Berger's Record: Semi-Cactus Dahlia Tubers

Berger's Record Dahlias are far from subtle. This iconic red semi-cactus variety has flowers which, with their large heads of masses of quill-shaped pointed petals, look like exploding fireworks.

For dahlias that only grow to about 90 cm tall, Berger's Record can carry blooms of up to 20cm across on sturdy, upright stems, although you will have to nip out the side buds to get them this big. Most people prefer to have more flowers that are slightly smaller, unless they are for exhibition. Either way, they make wonderful subjects as cut flowers - just three in a vase is all that's needed, and they're long-lasting, too.

Growing Berger's Record Dahlias

All dahlias do best in deep rich soil with good drainage in a sunny spot. If it is windy they will need staking. They are greedy, thirsty plants so will need watering in dry spells, and they will always flower that little bit better if there is a bit of soluble food in the watering can once every couple of weeks.

They are quite compact plants and so will do well in pots but however you grow them it is important to stake them well and avoid a windy spot, as the heavy flower heads can snap off.

It is generally more convenient to put support stakes in at planting time, rather than leaving it until there is foliage in the way.

This flower has quite a presence in the border, especially alongside other fiery-coloured dahlias and late-summer flowering perennials.

Did You Know?

Introduced in 1964 by Wilfried Bergerhoff, you'll also find Berger's Record listed as Berger's Rekord and Berger Record. The RHS Nomenclature Committee is overworked...

A favourite for the show bench, you'll often see Berger's Record Dahlias in local late summer flower shows. If you want to compete, remember to disbud to get the biggest flowers possible!

If you ignore seed, Dahlias can be planted at three stages: as tubers, rooted cuttings and pot-grown plants.

Tubers can be planted at any time from March onwards. The hole should be at least double the diameter of the tuber laid out on the ground. Incorporate about 25% well rotted compost and if drainage is in any way doubtful then add plenty of horticultural grit as well. Plant one tuber per hole, leaving 60-80 cms between plants (depending on final size) and make sure the tuber is covered with 10-12 cms (4-5") of soil. This is important as it will insulate the tuber against frosts in March-May as they will take a couple of months to show.

Rooted cuttings, which are available from early April onwards, will need to be potted up and kept in a sunny and frost free place until they are ready to be planted out in mid May. Their treatment then is the same as for tubers except they are planted level with rather than 10 cms below the surrounding soil level.

Pot grown plants are not delivered until June, and are then planted out immediately in the same way as an established rooted cutting.

The more you deadhead, the more flowers you'll get.

*Surcharges to the Highlands and Islands still apply.

Because couriers sometimes experience delays, we schedule delivery by week, not by day. Therefore, please plan your planting day for the weekend at the end of the delivery week or for the week following delivery, at the earliest.
We will email you the day before your plants are due to arrive.

Payment: We do not charge your card until we begin to prepare your order for packing.

Guarantee: If any plants die within a year, we will replace them. We only ask that you follow our planting & growing instructions and sent us clear photographs of the dead plants in situ, so we can help to make sure that the replacement plants succeed. You only pay for the delivery of the replacements.

Please note that our guarantee is void if there is a hosepipe ban in your area: your newly planted hedging must be watered in dry weather while it is establishing. The best way to water is very thoroughly every few days: at least once a week in summer if there is no heavy rain.

Our nursery has been supplying container grown and bareroot hedging plants to gardeners, farmers and town planners since 1949. Our website started in 2003, so we do understand the concerns that you may have about buying hedging plants online. If any of your plants are damaged when they arrive or if you are otherwise not satisfied with your order after you inspect it, please repackage it and contact us. We will give you a refund or send replacements and send a courier to come and collect the unwanted plants.
