Follow our advice to have magnificent Calla lilies:

Planting Zantedeschia

Zantedeschia bulbs are planted as early as early spring at 4-5 cm deep, from March to May.

  • Respect a distance of about 30 to 40 cm between each bulb because Calla lilies have large leaves and need space.
  • Choose a sunny place but not burning.
  • Beware of soils that are too dry because calla lilies need a cool moist soil.

Watering the Zantedeschia

Watering Zantedeschia outdoors:

You can grow your Zantedeschia outdoors as long as you maintain a dormant period of at least 2 months per year without any water supply.

  • After flowering, reduce watering until the leaves turn yellow
  • Once the leaves have wilted, stop all water supply
  • Gently resume watering at least 2 months later

Water little at first then regularly as soon as the flowers appear, until the end of the flowering period.

Calla lilies grow very well at the edge of a pond, which reveals its great water needs.

But be careful, we are talking about a semi-aquatic plant, because it needs a period without water of at least 2 months, usually during the summer season.

Watering Zantedeschia indoors:

You can grow your Zantedeschia both in pots and indoors as long as you keep it dormant for at least 2 months a year without any water supply.

  • After flowering, reduce watering until the leaves turn yellow
  • Once the leaves have wilted, stop all water supply
  • Gently resume watering at least 2 months later

Pruning, maintenance of Zantedeschia

  • Cut short as soon as first frosts.
  • It is not necessary not cut until the leaves have completely yellowed, because that's when they build up their reserves for the next flowering.

For a spectacular bloom, add special bulb fertilizer.

Protecting calla lilies in winter

Zantedeschia resists quite well in the cool of winter.

In regions further north, protect the rhizomes by putting a good layer of mulch.
As a mulch, you can use dried leaves, glitter hemp or from linen or even ferns.

Trick : Before winter, take part of the rhizome and put it in a pot in your house and you will have calla lilies in winter.

Calla lilies in a pot, how to take care of it

Once the foliage is totally wilted, you can cut the leaves as short as possible.

  • Take out the bulb of its pot, taking care to lightly clean it of the soil that surrounds it.
  • Install it for the winter in a cool place but where it does not freeze throughout the winter
  • This place must also be good dry and without light, a small pierced shoebox for example.
  • At March, you can take out your bulb and replant it in new soil.
  • Then resume watering when the soil is dry and your calla lilies will bloom again.

You can do the same operation without removing the bulb from its pot but the soil will have to be renewed approximately every 2 years.

To know about Zantedeschia

This bulbous perennial is from south africa and not from Ethiopia as its Latin name suggests.

It grows naturally in marshy areas which are very humid during rainy periods and dry during winter periods.

Particularly exotic, it is perfectly suitable for wet areas like water pieces but will also be the perfect plant for your beds, borders or isolated tuft.
