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.
Bulbs live, like us, in the three-dimensional world, but our appreciation of them depends heavily on the fourth dimension: time. They emerge, they bloom, and they fade according to the weather and their internal clocks. First out of the gate in this collection of deer- and rodent-resistant bulbs are Snowdrops (400 bulbs per crate) and Winter Wolf’s Bane (400 bulbs). They are followed by Glory of the Snow (400 bulbs) and daffodils Tête-à-Tête (100 bulbs) and Jetfire (100 bulbs). The show ends, after a pause, with daffodil Sun Disc (100 bulbs). For a perennial performance, you must wait to mow until the bulb foliage has completely yellowed. Sold in crates of 1500 only. Each component is packed separately and labeled and can also be purchased on its own. Introduced 2022.

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.
