Varieties of Rose Callas

There are numerous varieties of rose callas, each with its unique charm and characteristics. Some notable varieties include:

• Picasso: Known for its vibrant pink flowers with dark, blotched centers.

Cultivation

Soil and Sunlight

Rose callas prefer well-draining, slightly acidic soil with a pH between 6.0 and 6.5. They thrive in full sun to partial shade, with at least 6 hours of direct sunlight per day.

Planting

• Plant the rose calla corms or tubers shallowly, with the pointed end facing upwards.
• Space the corms or tubers about 6 inches apart.
• Cover them with soil, leaving the top of the corm exposed above the surface.
• Water thoroughly after planting.

Watering

Rose callas require regular watering, especially during the growing season. Allow the soil to dry out slightly between waterings, but avoid letting it become completely dry.

Fertilizing

Fertilize rose callas once a month during the growing season with a balanced liquid fertilizer. Avoid over-fertilizing, as this can lead to root burn.

Maintenance

Deadheading

Deadheading spent blooms will encourage the plant to produce more flowers. Simply remove the flower stalk from the base.

Staking

Tall varieties of rose callas may require staking to support their heavy flowers. Use a stake that is taller than the plant and insert it into the soil beside the corm.

Overwintering

In cold climates, rose callas should be overwintered indoors. Dig up the corms or tubers after the first frost and store them in a cool, dry place.

Common Problems

Aphids

Aphids are small, sap-sucking insects that can infest rose callas. Use an insecticidal soap spray to control aphids.

Snails and Slugs

Snails and slugs can damage the foliage of rose callas. Use slug bait or create a physical barrier around the plants to deter pests.

Botrytis

Botrytis is a fungal disease that can cause brown spots on the flowers and leaves. Avoid overwatering and provide good air circulation to prevent this disease.

Conclusion

The rose calla is a captivating and versatile plant that adds beauty and grace to any garden or indoor space. By following these care instructions, you can enjoy the vibrant blooms and lush foliage of these elegant plants for years to come.
