Where to plant
Like galanthus, crocus corms love soil enriched with organic matter with good drainage, and look
their best naturalised in grass, or under trees. They love full sun or partial shade and will tolerate any
How to plant in the ground
1. Crocus corms should be planted about 10cm deep in well-drained, gritty rich soil in a sunny
situation and approximately 7.5cm apart.
2. Fill the bottom of each dug hole with a thin layer of bulb compost which contains added grit
for free drainage.
3. Add another layer of bulb compost before replacing the soil or lawn over the bulb by
treading down the earth and water well.
How to plant in containers
Most crocus varieties will grow well in containers and look great either on their own or mixed with
other spring flowering bulbs.
1. Use good quality bulb compost mixed with horticultural grit and cover the drainage holes
with crocks to prevent it blocking with silt.
2. Plant approximately 1.5inches below the soil and 1-2 cm apart in your container
3. Move to a sunny, bright location once the corms begin to sprout.
1. Crocuses are generally low-maintenance plants but keep them watered if the weather is dry,
but don’t waterlog the soil.
2. Deadhead as soon as the flowers have gone over but don’t cut off the foliage until it has
3. Leave the foliage to grow for about 6-8 weeks after flowering. This allows the bulbs time to
build up resources to bloom again next year.
4. When mowing the grass, try to avoid the foliage as much as possible.
5. Top dress with rich compost in spring, when new growth appears.
Pests and Diseases
Rodents can be a real problem as they like to dig up the corms so you may have to protect borders
or planted areas with some chicken wire. Slugs and snails will also go for the new shoots so place a
layer of grease or a copper band around pots.
