Zantedeschia elliottiana Picasso - Calla Lily

Plant your Calla 'Picasso' bulbs from March to April, at a depth of 12cm (5in), spaced 15cm (6in) apart, in a moist location. Apply organic fertilizer at planting and at least once a year. Cultivating them in large pots is possible, ensuring regular watering to keep the soil moist, with fertilizer applied every 2 months during the growing season. Mulch them at the first sign of cold weather, as they are sensitive to winter humidity and severe frosts, and are moderately hardy. In pots, store them during the winter. They will form beautiful flowering clumps from June to August in a few years. You can cut back the foliage after the first frost.
