FAQs

When is the best time to plant these Dahlia tubers?

Plant the tubers outdoors in April, once the risk of frost has completely passed in your area. Ensure they are in a sunny spot with well-drained soil.

How large do the flowers typically get?

These are 'Dinnerplate Dahlias,' known for their enormous flowerheads. While exact size can vary, they are bred to produce very large, dramatic blooms.

Can I grow these in pots?

While they are ideal for garden borders, they can be grown in large containers with adequate depth and volume, provided they receive full sun and consistent watering and feeding. Ensure good drainage.

How long do the cut flowers last in a vase?

Dahlias from this collection have an impressive vase life. With proper care, such as cutting stems in the morning and removing lower leaves, they can last for over a week.

What should I do with the tubers over winter?

After the first frost, cut the stems down and carefully lift the tubers. Dry them, then store them in a cool, frost-free place, perhaps covered in peat or sawdust, until replanting the following spring.

Do I need to stake these dahlias?

Yes, due to the large size of the dinnerplate blooms, staking is highly recommended to support the plants and prevent them from bending or breaking.

Are all the varieties in the collection the same type of flower shape?

No, the collection features six varieties with diverse flower shapes and colours, including the frothy blooms of 'Penhill Watermelon' and the luminous halos of 'Kelvin Floodlight'.

Troubleshooting

Tubers not sprouting

Ensure tubers were planted at the correct depth with the sprout facing upwards. Check that the soil is not waterlogged, as this can cause rot. Wait until the soil has warmed sufficiently after the risk of frost has passed.

Poor or small flower production

Ensure the plant is receiving adequate sunlight (at least 6 hours per day). Increase watering and feeding, especially during the main growing season. Remove any pests that may be affecting the plant's health.

Wilting leaves

Check for consistent soil moisture; the plant may be too dry. Ensure good drainage, as waterlogged soil can cause root rot. Inspect for any signs of pests or diseases.

Plant falling over

Provide adequate support with stakes, especially for the larger dinnerplate varieties, before the plant becomes too tall and heavy. Tie stems loosely to the stakes as the plant grows.

Setup, Compatibility & Care

Planting: Plant the tubers outdoors in April, ensuring the risk of frost has passed. Choose a sunny position with well-drained soil. Tubers should be planted with the eye or sprout facing upwards, approximately 10-15 cm deep.

Watering: Water the tubers well after planting. Continue to water regularly throughout the growing season, especially during dry spells, to support the development of large blooms.

Feeding: Feed your dahlias regularly with a suitable plant food throughout the growing season. This helps to promote healthy growth and abundant flowering.

Support: Taller varieties may require staking to support the weight of the large flowerheads and prevent damage from wind or heavy rain.

End of Season: After the first frost, cut down the stems to about 15 cm above the ground. Carefully lift the tubers, dry them thoroughly, and store them in a cool, frost-free place (e.g., peat or sawdust) for the winter. Replant the following spring.
