Planting Guide
Plant Wittem Dahlia tubers after the last spring frost in full sun and well-drained soil. A little care at planting time helps set them up for a long season of blooms.
- Depth: 1–2 inches with the “eye” of the tuber facing upward.
- Spacing: 12–18 inches apart to allow for airflow and healthy growth.
- Watering: Keep soil evenly moist, but not soggy, especially during early growth.
Ongoing Care
- Watering: Once sprouts appear, water deeply 2–3 times per week, letting the soil dry slightly between waterings.
- Fertilizer: Feed every 3–4 weeks with a low-nitrogen fertilizer to encourage strong stems and more blooms.
- Staking: Tall plants benefit from support to keep stems upright.
- Deadheading: Remove spent flowers regularly to keep the plant blooming.
Growing in Containers
- Select a sturdy pot 12–16 inches wide with drainage holes.
- Fill with high-quality potting soil mixed with compost for added nutrients.
- Place the container in full sun and care for as you would in the garden.
FAQs

These dahlias feature refined white blooms on medium-sized plants that perform well in both gardens and containers. Their long bloom season and excellent cutting quality make them a versatile choice.

- Planting: Full sun, well-drained soil, 1–2 inches deep, spaced 12–18 inches apart.
- Watering: Keep soil lightly moist during dry spells.
- Fertilizer: Apply a bloom-focused fertilizer once plants are established.
- Support: Stake taller plants as they grow.
3. Can I grow them in pots?

4. How do I get more flowers?

5. How should I store the bulbs for winter?
Since dahlias are not frost-hardy, lift and store the tubers after the first frost:
- Carefully dig up bulbs and brush off soil.
- Let them dry in a cool, dry space for a few days.
- Store in peat moss or sawdust in a frost-free area.
- Check occasionally for signs of rot or dryness and adjust as needed.
Replant the following spring for another season of elegant blooms.
