Choosing the Right Location
When planting Zantedeschia, it is important to choose the right location. Zantedeschia thrives in full sun to partial shade and prefers well-drained soil. Make sure to plant your Zantedeschia in a location that receives at least 6 hours of sunlight per day.
Preparing the Soil
Before planting your Zantedeschia, it is important to prepare the soil. Zantedeschia prefers rich, well-drained soil with a pH level of 6.0 to 7.0. You can improve the soil by adding organic matter such as compost or well-rotted manure.
Planting Zantedeschia
To plant Zantedeschia, dig a hole that is twice as wide and deep as the plant’s root ball. Place the plant in the hole and backfill with soil, making sure to firm the soil around the plant. Water the plant thoroughly after planting.
Watering and Fertilizing
Zantedeschia requires regular watering to keep the soil moist but not waterlogged. During the growing season, water your Zantedeschia once a week, and reduce watering in the winter months. Fertilize your Zantedeschia with a balanced fertilizer every 4-6 weeks during the growing season.
Pruning and Deadheading
To keep your Zantedeschia looking its best, it is important to prune and deadhead regularly. Remove any dead or yellowing leaves, as well as spent flowers, to encourage new growth and flowering.
Pest and Disease Control
Zantedeschia is relatively pest and disease-resistant, but it can be susceptible to aphids, slugs, and snails. To control pests, you can use insecticidal soap or neem oil. Keep an eye out for signs of disease, such as yellowing leaves or rot, and treat promptly.
Overwintering Zantedeschia
In New Zealand, Zantedeschia is considered a tender perennial and may need protection during the winter months. If you live in a colder region, consider lifting and storing your Zantedeschia bulbs indoors during the winter.
Propagation
Zantedeschia can be propagated by division or by seed. To propagate by division, simply divide the rhizomes in the spring or fall and replant them in a new location. To propagate by seed, collect the seeds from the flowers and sow them in a seed tray.
