Plant my autumn crocus

Colchics like the sun. Plant them in a rich, drained without being dry, deep soil. You can also naturalize the sturdy colchic in a lawn. Dip the clumps in a tray filled with water to moisten them well. Plant them when the water is no longer flowing out of the bucket. Prepare the soil: make holes 10-15 cm deep, leave a spacing of 10 to 15 cm per foot, and mix the soil with compost and sand if it does not match the description above. Bury the plants 10 cm deep. Cover with soil while tamping gently to avoid air around the roots, then water. If you want to plant in pots, mix compost with potting soil; add some sand, and put everything in a pot deep enough - at least 30 cm. Then plant your crocuses 10 cm deep, then water.

Water my autumn crocus

If in pot, water every 3-4 days in the first few weeks - then less and less. In case of drought during the summer, water but not excessively, once a week, in the morning if you can.

Fertilize my autumn crocus

With a respectful approach to soil life, it's always better to fertilize a little in advance with organic material that will decompose; spread out a compost that isn't entirely decomposed, with well decomposed manure at the plant's base, and incorporate over 10 cm with a hoe. This operation is carried out in winter so that earthworms and bacteria have enough time to do their job.

Propagate my autumn crocus

You can propagate by dividing the "corms" - this is the name of the colchicus roots in summer. Choose old plants, which do not bloom much anymore. Dig them up with a spade, taking care not to damage the roots. Separate the corms, and replant without waiting at 10-15 cm intervals.
