Boom Boom White Dahlias

Boom Boom White: Ball Dahlia Tubers

The classy Dahlia Boom Boom White is one of the best white ball dahlias you can grow for your garden. The neatly rounded, tightly packed clusters of petals have a hint of greenish-yellow at the centre. This prolific bloomer produces flowers 10cm across but if you pinch out some of the buds, you'll get even bigger flowers, up to 15cm in diameter. Plants are compact, about 1m tall with fresh, green foliage which sets off the flowers perfectly.

Growing Boom Boom White 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.

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

Planting Companions for Boom Boom White

It is versatile enough to be grown in a sunny mixed border, especially in a white-themed garden and will be happy in a large container.

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.
