These are fall-planted, spring-blooming bulbs. Get them in the ground after soil temperatures cool but before it freezes, and they will root over winter and bloom on their own schedule in spring.
Unboxing
- Open right away. Remove bulbs from the packaging and check them over; firm, dry bulbs with papery skins are healthy and ready to plant.
- Store cool if needed. If you cannot plant immediately, keep bulbs in a dry, dark spot between 45 and 60 degrees for up to a few weeks.
Planting
- Pick your spot. Choose a site with full sun to part sun and soil that drains well; avoid low areas where water stands.
- Loosen the soil. Work the bed 8 to 10 inches deep and mix in compost if your soil is heavy clay or very sandy.
- Set the depth. Plant larger bulbs such as Tulips, Allium, and Camassia 5 to 6 inches deep, and smaller bulbs like Anemone and Scilla about 3 inches deep, pointed end up.
- Space for drifts. Set bulbs 3 to 6 inches apart depending on size, planting in clusters of 10 or more for a natural look.
- Backfill and water. Cover, firm the soil gently, and water once well to settle everything in.
- Mulch lightly. Add 2 inches of mulch to moderate soil temperature and reduce winter heaving.
Watering
- Fall soak. Water once at planting, then only if fall is unusually dry.
- Spring moisture. Keep soil evenly moist while foliage and flowers are actively growing.
- Summer rest. Stop supplemental watering once foliage yellows; dormant bulbs prefer drier soil.
Feeding
- At planting. Mix a balanced bulb fertilizer or bone meal into the planting hole.
- Each spring. Scatter a light application of balanced fertilizer as shoots emerge to fuel next year's blooms.
After Bloom Care
- Deadhead spent flowers. Snip off faded blooms so energy goes back into the bulb, but leave Allium seed heads if you enjoy the look.
- Let leaves ripen. Allow foliage to yellow and die back naturally before removing it, usually 6 weeks after flowering.
- Let them spread. Camassia, Scilla, Anemone, and Allium naturalize well; divide crowded clumps in late summer if needed.
