When to Plant
Delivery & Planting Times
Spring-flowering bulbs must be planted in the fall. They need cool soil to make roots before the onset of winter. Cool fall weather arrives at different times from north to south and from high elevations to low.
Please note that the temperature of the soil lags behind the air temperature. You can generally plant later than the windows provided in this map. As long as the ground is not frozen, you can still plant.
Winter begins on the shortest day of the year. From there, the days increase in length—imperceptibly at first, then with noticeable speed as we approach the equinox. These bulbs herald the news that everyone has been waiting to hear: spring has arrived. First out of the gate are Snowdrops (300 bulbs per crate), followed in close succession by Dutch crocuses Flower Record, Jeanne d’Arc, and Pickwick (900 bulbs); White Squill (300 bulbs); and Glory of the Snow (500 bulbs). For a perennial performance, you must wait to mow until the bulb foliage has completely yellowed. Sold in crates of 2000 only. Each component is packed separately and labeled and can also be purchased on its own. Introduced 2022.
Note to customers in warm climates: Some of the bulbs in this collection require prechilling and are unlikely to perform well beyond the first spring.

There are no rules for planting a Color Your Grass collection. Jacqueline van der Kloet, the Dutch designer who inspired Color Your Grass, suggests the following approach:
1. Choose a sunny location where the soil drains well.
2. Mow the grass to improve the visibility of the bulbs.
3. Open the bags and mix the bulbs in a bulb crate or wheelbarrow.
4. Toss the bulbs out onto the grass.
5. Plant the bulbs where they lie.
Detailed instructions for planting according to Jacqueline’s method will be included with every order.
