When to Plant?
Be sure to plant the bulbs in such a way that they lie in a horizontal position with most of the eyes pointing upward. After planting, cover the bulbs with soil and firm the ground with your hands. Now, water them thoroughly. The soil should be kept moist, but not wet, as over-watering can cause the bulbs to rot.
If you are considering to plant the tall varieties of dahlia, then set stakes into the ground. To promote the growth of large blossoms, pinch the new growths, except the leader buds. Fertilization is also be required for promoting the growth of better and larger blossoms. The right time for applying fertilizer is about one month prior to the blooming season.
How to Plant the Bulbs in Pots?
Plant the rest of the bulbs in the same way, and then place the pots in a sunny location. Once sprouting has occurred, water the bulbs to keep the soil moist. Do not cut the plant or remove the foliage immediately after the end of the blooming season. Instead, let them remain there for some time.
Then dig the soil around the bulbs and gently lift them. Make sure that you do not cause any injury to the bulbs while doing so. Allow the bulbs to dry in air for a few days, after which they can be stored for the next year in a dry and cool place. Containers filled with peat moss, as well as paper bags can be used for storing dahlia bulbs.
