How to Plant Crocus Bulbs

When to plant:

Crocuses are hardy bulbs that happily survive outdoors through the winter. For
the best display of flowers, plant crocus bulbs between September and November.
If you receive them late, you can still plant as late as December—just be sure
to store them in a cool, dry, and well-ventilated place until planting. Crocus
bulbs should always be planted in the same season they’re supplied, as they
won’t keep until the following year.

Note: Fall-flowering crocus are planted in late
summer (August-September) and emerge from the ground in fall (November). Be
prepared to plant them as soon as possible after receiving them as they will
benefit from time in the ground establishing roots before they bloom in fall.

Where to plant:

Crocuses thrive in borders, lawns, rock gardens, and patio containers. They
enjoy a spot in full sun but will also tolerate light or dappled shade. If
planting in containers, use a peat-free multipurpose compost. For heavy soils,
especially those rich in clay, mix in compost and add grit or sand to improve
drainage—crocus bulbs dislike sitting in waterlogged soil.

Planting depth and spacing:

Plant crocus bulbs about 5–10 cm deep, with the pointed end or emerging shoots
facing upwards. If planting later in the season and shoots have already started
to grow, don’t worry—plant them at the normal depth, keeping the shoots intact
below the surface. Space bulbs 5–15 cm apart, either in small clusters for a
natural look or in larger drifts for a striking carpet of colour.

After planting:

Cover the bulbs with soil or compost and gently firm down. Water lightly if the
soil is very dry at planting time. Crocuses generally don’t need watering
through winter unless you experience very mild, dry conditions. In spring,
water only during prolonged dry spells.

Ongoing care:

Crocuses are very low-maintenance. After flowering, allow the foliage to turn
yellow and die back naturally before removing it. This process feeds the bulbs
for the following year. Leave the bulbs in the ground year-round, where they
will rest through summer and bloom again the next spring. With each passing
year, they often naturalize and multiply, creating an even more impressive
display.
