How to Plant Dahlia Tubers: A Detailed Guide to the Planting Method

1. Selecting the Tubers

Before planting, you should select the tubers. When choosing, try to pick ones with healthy roots and plump, fleshy tissue, as this will improve their survival rate.

2. Planting Method

1. First cut off any roots that have already dried out. If there are too many tuberous root clumps, you can use a sharp blade to help separate them, and when separating, leave some lateral roots and adventitious buds on each stem, otherwise they will not survive.

2. Once the root clumps are treated, you can begin planting. If planting in the ground, first dig a large hole 20 cm deep, then remove the stones and weeds inside. If the soil contains a lot of sand, add a little soil-based fertilizer. At the same time, to make sure it has enough nutrients, you can also add some organic fertilizer while hoeing the soil.

3. It usually grows very tall. To prevent damaging its root clumps later when setting up a support, it is best to place a stake at its root clump when planting, positioned close to the growth buds, then backfill with soil and water it.

4. It grows very fast in June. If you have not given it a support by then, set one up immediately, and set one at the base of each plant, but do not damage the tubers.

5. When setting up the support, it is best to keep it about 5 cm from the stem, then find some string to tie the stem and the support together, but do not tie it too tightly.

6. Afterwards, to make its flowers look better, remove its leaf axils and small side branches promptly when buds appear, leaving only the buds below the stem, and after flowering, also promptly cut off the spent flowers.

7. By October to November, it basically stops flowering. At this point, cut off all the branches 10 cm above the ground, leaving only the leaves.
