Planting White Calas

Choosing a Site

* White calas prefer well-drained, moist soil rich in organic matter.
* Select a location that receives full sun to partial shade.
* Avoid planting in areas with standing water, as this can lead to root rot.

Planting Instructions

* Dig a hole twice the width of the bulb and just as deep.

* Fill the hole with soil and gently firm it down.
* Water thoroughly after planting.
* Space bulbs 4-6 inches apart.

Care of White Calas

Watering

* Water regularly, especially during hot, dry weather.
* Avoid overwatering, as this can lead to root rot.
* Allow the soil to dry out slightly between waterings.

Fertilizing

* Feed white calas with a balanced fertilizer in the spring and again in the summer.
* Avoid overfertilizing, as this can damage the plants.

Mulching

* A layer of mulch around the plants will help to retain moisture, regulate soil temperature, and suppress weeds.
* Use organic materials such as compost, shredded leaves, or bark.

Dividing

* Divide white calas every 3-4 years to prevent overcrowding and promote flowering.
* Dig up the clumps in the fall and separate the bulbs.
* Replant the bulbs in a new location.

Design Ideas with White Calas

Borders

Pots

* Place the pots in a location that receives bright, indirect light.

Cut Flower Arrangements

* Cut the stems clean and place them in a vase with fresh water.
* Add a few drops of flower preservative to keep the blooms looking their best longer.
