Crinum planting

The crinole flourishes naturally along lakes or streams in all tropical regions of the world. It likes rich, deep and cool soils . This plant appreciates the sun or the partial shade but cannot do without light.

> Crinum in the ground

The planting of the crinum preferably takes place in the fall or in the spring. 

  • Choose your floor according to the requirements of the crinole.
  • Dig a hole in it about 60 cm deep, the bulb rooting deeply as it grows.
  • Backfill the hole by enriching it with a mixture of about 10 liters of potting soil, compost or manure on the one hand and extracted soil on the other.
  • Then bury the bulbs so that the neck of the bulb is on the surface and leave about 50 cm between each one.
  • Water abundantly.

> Crinum in pot

This perennial plant can also be grown in pots . Make sure, however, that the diameter of it is at least twice as large as the diameter of the bulb . Then, as for the crinole grown in the ground, make sure that the soil is enriched with the appropriate compost. Once planted, make sure it is watered generously .

Multiplication of the crinum by division of the cloves

To multiply your crinums, the best time is spring . The company is not easy but should go well if you follow these tips:

  • Carefully lift the bulb out of the ground.
  • Cut off the small bulbs, or cloves, that have formed around the bulb.
  • Plant them directly in the ground or in pots.
  • If you have planted them in a pot, place it in the light.
  • Water lightly for two months then grow them as adults.

You will definitely need a little patience, say 3 years, before the new bulb will bloom again. When propagating, be careful because this perennial does not like to be disturbed .

Crinum maintenance

The crinum is not demanding except that it is greedy in water and does not like to be moved. It only requires plenty of water and liquid fertilizer during its growth phase.

> Crinole size

The size of the crinum is relatively simple. At the end of the year (November and December), while the plant is resting, gradually remove the yellowed or damaged parts of the leaves.

> Maintenance of the crinum in pot:

Make sure that the water does not stagnate in the pot: remember to empty the saucer after watering.

crinole in winter

The crinum being quite chilly , do not hesitate to mulch those who are outside. Those in pots will have to be brought indoors at the beginning of autumn until the fine days of spring.

Crinum diseases

The crinum can be susceptible to certain diseases or certain pests:

  • For example, it can be invaded by scale insects . In this case, apply a cotton ball soaked in alcohol on the colonizing insects.
  • Slugs and snails are particularly fond of young crinum shoots… To prevent them from making your plants their dinner, turn the soil over and dig up the eggs. Then lay out ashes or sawdust there, which will prevent their coming.
  • If your perennial is struggling to flower, or does not flower at all, and at the same time its leaves grow a lot, it is certainly that it lacks light.
