You should plant crocuses between September and December. The best month for planting is different for each variety and depends on the temperature. Autumn-flowering crocuses should go in the ground as early as September, while you should plant spring-flowering crocuses between October and December, once the soil has lost its warmth. Whatever the variety, make sure that you plant them before the first frosts. Most varieties of crocus flower in February and March and some even last until April. Autumn crocuses flower in September/October, adding a splash of colour to what can be a grey season!
So you can enjoy working in your garden between September and December, as long as the temperature is above freezing. Planting lots of crocuses together is extremely effective and you can plant around 200 to 300 tubers per square metre to create a huge explosion of colour If you want a more natural effect, scatter the tubers across the border and plant them where they land. Choose different varieties and colours to create variety in your garden. Of course, crocuses also look attractive in a lawn or adding a splash of colour under a tree or bush. They like to be in full sun and also respond to light, so the flowers will open when the sun is out and stay closed on cloudy days. If you want to plant crocuses underneath a tree, you therefore need to make sure that they will get enough light and that the soil you plant the tubers in is rich in nutrients, well-aerated and well-drained. If the soil is heavy, you can potentially add sand or grit to improve drainage. Dig a planting hole that is around three times the height of the tuber and wide enough that the roots won't get damaged. Place the tuber in the whole with its pointed end upwards and its roots on the soil. Fill the hole with fresh potting soil and tamp it down lightly. Water if the tubers have been dry for a long period. Protect any crocuses that have started to sprout once the frosts arrive.
Planting crocus tubers in a pot
You can also enjoy crocuses in a basket or pot on your patio or balcony, as well as in the open ground – again, make sure that you plant them before the first frosts. Make sure that you choose a decorative flower pot with enough room to space the plants out, so the roots don't destroy the other tubers as they grow. You can add organic fertiliser to the potting soil to make sure that the plants grow well. We recommend that you protect tubers in pots against hard frosts, by using bubble wrap, for example, or protective covers. you can also move the pots temporarily into your shed.
