Early-spring crocus have much to offer, and they neednt be restricted to the flower bed. Just imagine a lawn filled with blooms in colors such as bright purple, white, gold, pink, or pale lavender. Once established, the thick carpets of color require surprisingly little care.
Crocus bulbs can add a cheerful pop of color to lawns and gardens when they bloom in early spring. Their flowers come in shades of purple yellow white, orange and more, brightening up dormant winter landscapes. Planting crocus bulbs in grass can create a beautiful, naturalized look as the blooms emerge right from your lawn.
With proper planning and care, crocus bulbs can thrive when planted in grass Here is a complete guide to successfully planting crocus bulbs in your lawn
Choosing the Right Crocus Varieties
Not all crocus varieties are well-suited for planting in grass. The best options are smaller early blooming types that can withstand being mowed. Many gardeners recommend Crocus tommasinianus also known as tommies. These smaller crocus reach just 4-6 inches in height and bloom in early spring before most lawns need mowing.
Other good crocus varieties for lawns include:
-
Crocus chrysanthus – Early bloomer with height of 4 inches.
-
Crocus sieberi – Small, tolerant of mowing. Height of 3 inches.
-
Crocus biflorus – Petite blooms reach 2-3 inches tall.
Larger, later crocus varieties like Crocus vernus tend to struggle more when planted in grass. Opt for the small, early bloomers for best results.
When to Plant Crocus Bulbs in Grass
Timing is important when planting crocus in lawns. They should be planted in early fall, about 6-8 weeks before the first hard frost in your area. This gives the bulbs enough time to establish roots before winter dormancy.
Avoid planting crocus too early in fall, as they may bloom prematurely and risk frost damage. Plant them in September through November for most climates.
Preparing the Planting Area
When preparing to plant crocus bulbs in an existing lawn, remove grass and weeds from the planting area. You can dig up pieces of sod or use a grass killer, carefully following product instructions.
Once the area is cleared, loosen the soil with a tiller or garden fork. Mix in bulb fertilizer, compost or other amendments to improve drainage and nourishment for the crocus. Crocus prefer soil pH between 6-7.
How Deep to Plant Crocus Bulbs in Grass
Proper planting depth is key for growing crocus in lawns. The general guideline is to plant crocus bulbs 3-4 inches deep in the soil. This gives them ample insulation from winter frosts while still allowing leaves and blooms to emerge.
Use a trowel or bulb planter to dig holes 3-4 inches deep. Place 1 crocus bulb in each hole with the pointed end facing up. Backfill holes with soil and tamp lightly.
Planting Methods
There are a couple methods you can use to plant crocus bulbs in grass:
-
Individual holes: Dig holes spaced 3-4 inches apart and plant one bulb in each hole. This gives you more control over placement.
-
Naturalizing: Randomly scatter bulbs across the lawn area, then lightly rake them into the soil. Creates a naturalized look.
Either method works, just choose based on your preferences and lawn space. Plant in clusters or drifts for best impact.
Caring for Crocus in Lawns
Once planted, crocus bulbs in lawns need:
-
Water: Keep soil moist while bulbs root in fall and when blooming in spring. Avoid overwatering.
-
Fertilizer: Apply bulb fertilizer when planting and again when growth appears in spring.
-
Mowing: Do not mow lawn until crocus foliage fully ripens and dies back. This ensures leaves can replenish the bulbs.
-
Weed control: Keep area around crocus bulbs weed-free. Weeds will compete for space, nutrients and moisture.
Long-Term Care Tips
Here are some long-term care tips for keeping crocus thriving in your lawn:
-
Reapply bulb fertilizer each fall.
-
Every few years, lift and divide bulbs after foliage dies back to prevent overcrowding. Replant immediately at proper depth.
-
Avoid using weed killers and insecticides, as they may damage bulbs.
-
Allow foliage to ripen completely before mowing over crocus each spring.
-
Add new bulbs every fall to ensure continued flowering as older bulbs fade.

Growing Crocus in Lawns
If youre thinking about growing crocus in the yard, there are several things to consider. If you like a lawn that is luxurious, lush, and heavily fertilized, planting handfuls of crocus may be a waste of time because the bulbs have little chance of competing with a stand of thick grass. If youre fussy about your lawn and you like it perfectly manicured, you may not be happy with the little guys popping up all over the place. Keep in mind that you wont be able to mow for a few weeks, or until the tops of the crocus turn yellow. If you mow too soon, the bulbs may not have the get up and go for another season of blooming because the foliage absorbs sunlight that converts to energy. Crocus is ideally suited for a spot where grass is sparse– possibly a spot under a deciduous tree or in a forgotten patch of lawn.
How to Grow Crocus Lawns
Plan (and plant) your crocus lawn carefully; with any luck, the bulbs will last for several years. Plant the bulbs when the ground is cool in autumn, six to eight weeks before the first hard frost. Choose a spot where the soil drains well. If youre planting crocus bulbs in existing turf, you can lift the turf and roll it back carefully. Dig a little compost or manure into the exposed soil, then plant the crocus bulbs. Roll the turf back into place and tamp it so it makes firm contact with the ground. If youre thinking that naturalizing crocus bulbs will provide a more natural appearance, youre right. For a truly natural look, just scatter a handful of bulbs and plant them where they fall. Steer clear of perfect rows.
