Ideal Time for Planting Zantedeschia Flowers

Zantedeschia flowers are best planted in the spring, after the last frost has passed. The ideal planting time depends on your location and climate, but in general, early to mid-spring is a good time to plant. In warmer regions, you can also plant in the fall, but make sure to avoid planting in the hottest months of the year.

Planting Zantedeschia Flowers

When planting Zantedeschia flowers, choose a site with well-draining soil and full sun to partial shade. The plant prefers slightly acidic soil with a pH between 6.0 and 6.5.

Dig a hole that's about twice the size of the plant's root ball and as deep. Add compost or aged manure to the soil to improve its fertility and texture. Place the plant in the hole, making sure the top of the root ball is level with the surrounding soil. Backfill the hole with soil, firming it down gently around the plant. Water thoroughly to settle the soil and remove any air pockets.

Fertilizer Tips for Zantedeschia Flowers

Zantedeschia flowers are heavy feeders and require regular fertilization to grow strong and healthy. Here are some fertilizer tips for growing Zantedeschia flowers:

  1. Use a balanced fertilizer: Zantedeschia flowers prefer a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium. Look for a fertilizer with an NPK ratio of 10-10-10 or 20-20-20.

  2. Apply fertilizer every two weeks: During the growing season, apply a balanced fertilizer every two weeks to provide your Zantedeschia flowers with the nutrients they need to thrive.

  3. Water well after fertilizing: After applying fertilizer, water your Zantedeschia flowers thoroughly to help the nutrients soak into the soil.

  4. Stop fertilizing in the fall: Stop fertilizing your Zantedeschia flowers in the fall to allow the plant to prepare for dormancy. Resume fertilizing in the spring when new growth appears.


Growing Zantedeschia flowers can be a rewarding and enjoyable experience. By planting in the spring and using a balanced fertilizer every two weeks during the growing season, you can ensure that your Zantedeschia flowers grow strong and healthy and produce beautiful blooms year after year.
