Tuber care
Once your tubers arrive, it's important that you care for them properly so they can grow into the beautiful plants you are hoping for.
Preparation for planting
-
Dahlias thrive in full sun, requiring at least 8 hours of sunlight daily for abundant blooms.
-
Choose a sunny garden spot with well-draining soil, or consider raising the garden bed to ensure proper drainage.
-
Before planting, it's recommended to enrich the soil with 5 to 10 cm of high-quality compost or well-rotted manure.
-
Dahlias must be staked to prevent them from toppling over due to the weight of their flowers and strong winds.
Planting
-
After you receive your tubers, store them in a cool, dry place indoors or under cover until all danger of frost has passed.
-
Do not plant tubers in waterlogged soil, whether in the garden or in pots; they will rot! If your area experiences excessive spring rains, it may be best to delay planting until the ground is not soaked.
-
When it's time to plant, dig holes or trenches that are around 10-15cm deep. Place the tubers on their sides, with the growing eye or shoot facing upwards. Leave a space of 30cm between tubers, then cover them with soil.
-
Do not start watering until the first green shoots appear.
Growing you dahlias
-
Remember to water your Dahlias consistently throughout the growing season, and water the plants at the soil level, avoiding the foliage.
-
Once your plants have 3 or 4 sets of leaves, it's time to pinch them. This means snipping out the growing centre to encourage low branching, which increases flower production and overall stem length.
-
Keep an eye out for slugs, snails, earwigs, and nematodes, as they can damage young plants, flowers, and tubers.
Tips and tricks
-
Dahlias don't need a lot of water; if in the ground, you can water every two or three days over the summer. In containers, they will need more regular watering.
-
When you cut off flowers, cut down to above the next set of leaves, this will stimulate more flowers to grow.
-
Regularly deadhead to ensure the plant's energy goes into new flowers, not seed production.
