Care and Culture Card
See basic growing conditions and care information below.
Grow plants of Constantia on slabs without any moisture retaining material at the roots. The plants appear to do best on hardwood slabs with fine-textured bark such as lilac or citrus. Provide high light levels and warm-intermediate temperatures during the growing season. Provide cool temperatures after flowering. Water regularly during active growth and at a maintenance level after flowering.
