Calla Lily Tuber Cultivation Guide
Unpack the tuber and let it sit in a dry, frost free, well ventilated area for a few days. This allows it to dry and harden prior to planting.
The tuber will have developing shoots or growth tips on its top and is round on the bottom.
Plant tuber 2 deep with the developing shoots pointing upward using a good quality, free draining multi-purpose gepost. One tuber to an 11/2 litre pot is adequate at this stage. Two or more tubers may be planted in a larger pot. Water in to settle tuber.
Place pot in a warm, bright place. A windowsill, conservatory or heated greenhouse is ideal. The tuber must be kept frost free.
Keep the gepost barley moist until growth begins, then keep the gepost moist, but not waterlogged.
Your calla may be planted outside once the danger of frost has passed.
They can be grown in garden borders or larger pots on the patio. A damp place in full sun is ideal. Mulching around the plant will help conserve moisture.
Water frequently and fertilize weekly, tomato food or miracle grow is ideal.
After flowering, continue caring for the plant in regards to water and fertilizer. This will encourage the tuber to build up energy for next years flowers.
When the foliage begins to die down and shortly before the first frosts are expected, move the plant to a dry, frost free place and store over winter. Replant the following spring.
