What is a Pre Cooled Bulb
Pre-cooled bulbs are tulip bulbs that have been stored at a constant cool temperature (around 5°C / 41°F) before shipping. This artificial “winter” ensures proper flower development, especially in warmer climates like California where natural chilling isn’t sufficient. Pre-cooling helps guarantee uniform growth, taller stems, and reliable blooms.
Plant Care Steps
Timing: Plant bulbs in late fall to early winter after soil cools (or directly after receiving pre-cooled bulbs).
Soil: Use well-drained soil enriched with compost. Avoid waterlogged ground.
Depth: Plant 6–8 inches deep, with pointed end facing up.
Spacing: 4–6 inches apart for mass planting.
Watering: Water well after planting; keep soil moderately moist but not soggy.
Fertilizer: Apply a balanced bulb fertilizer at planting and again in early spring.
After Blooming: Allow foliage to die back naturally to store energy in the bulb.
