When to plant Crocus bulbs?
Plant crocus bulbs in the fall when daytime temperatures are in the 60’s or lower on a consistent basis.
How to plant Crocus bulbs?
Crocus require soil that drains well. They do best when planted in an area that gets at least 4 hours of full sun per day.
Plant Crocus bulbs with the pointed end facing up 2-3” deep. Space Crocus bulbs 2-3” apart when planting.
Where is the best place to plant Crocus bulbs?
Crocuses are low growing (under 8”) early spring flowering bulbs. They can be placed the front of planting beds and borders, so they are easily seen. Crocus can also be planted throughout the lawn for a burst of spring blooms among the grass.
How to plant Crocus bulbs in grass?
Using a small shovel, bulb auger or bulb planter create holes throughout the lawn. Place the Crocus bulbs 2-3” deep in the holes that you removed the grass from. Place the grass and soil that was removed to plant the Crocus in back over the crocus. The bulbs will break through the soil in spring and grow among the grass.
Planting Crocus bulbs in Pots
Crocus can be planted in pots in temperate climates that do not experience many freeze and thaw cycles. If Crocus are planted in pots in above ground containers in a climate that has varying winter temperatures the pots will need to be insulated to protect the bulbs from the effects of the freezing and thawing that may occur.
