Soil Type

Water: Zantedeschia pentlandii prefers consistently moist environments with well-drained soils, requiring weekly watering to maintain ideal moisture levels. It adapts to seasonal water changes and is typically grown outdoors, benefiting from natural rainfall. Climate zones are important for successful cultivation.

Fertilize: Zantedeschia pentlandii thrives with phosphorus, aiding in larger flowers. Use base fertilizer and thin compound fertilizer bi-weekly until flowering. Excess nitrogen enhances leaf growth at the cost of flowers. For potted plants, apply a 2% ferrous sulfate solution every other month to enhance leaf thickness and aesthetic appeal.

Pruning: Zantedeschia pentlandii features trumpet-shaped flowers and benefits from early to late spring pruning to remove dead foliage and spent stalks, promoting new growth. Trimming leggy stems maintains compactness, enhances aesthetics, improves air circulation, and prevents disease, ensuring healthy growth and prolonged blooming.

Propagation: Zantedeschia pentlandii propagation involves sowing fresh seeds in well-draining, fertile substrate. Consistent moisture and warmth are vital for germination. Once seedlings are strong, they can be transplanted to individual pots before moving to their final growing location.
