Belladonna Amaryllis bulbs are easy to establish. You can pot them up indoors for a first bloom or plant them directly in the garden as soon as they arrive.
Unboxing
- Open right away. Remove the bulbs from the packaging and check that they are firm and dry.
- Store briefly if needed. Keep unplanted bulbs in a cool, dry, dark spot with good air flow for up to a couple of weeks.
Planting Outdoors
- Pick a sunny spot. Choose a site with full sun to partial shade and well-drained soil.
- Loosen the soil. Dig and turn the top 10-12 inches, mixing in compost if your soil is heavy clay.
- Set the depth. Plant bulbs 6-8 inches deep with the pointed neck facing up.
- Space them out. Allow 9-12 inches between bulbs so clumps have room to expand.
- Backfill and water. Firm the soil gently and water once to settle it in.
Planting in Containers
- Choose the right pot. Use a container with drainage holes, at least 8 inches deep.
- Use quality mix. Fill with a well-draining potting mix; avoid heavy garden soil.
- Leave the neck high. In pots, plant so the top third of the bulb sits above the soil line.
- Give it light. Place in a bright window or on a sunny patio, then move outdoors and plant in the ground the following fall.
Watering
- Water while growing. Keep the soil lightly moist during leaf growth and flowering, about once a week.
- Ease off after bloom. Reduce watering as the foliage yellows and the bulb heads into dormancy.
- Never let it sit wet. Soggy soil is the main cause of bulb rot, so always allow excess water to drain.
Feeding
- Feed in spring. Apply a balanced slow-release fertilizer as new growth appears.
- Support next year's bloom. A second light feeding after flowering helps the bulb store energy.
Seasonal Care
- Leave the leaves. Let foliage die back naturally; it recharges the bulb for next season.
- Mulch in cold zones. In zones 5-6, add 2-3 inches of mulch over the planting area for winter protection.
- Divide when crowded. Lift and separate clumps every 4-5 years once bloom count drops.
