Unless you live in an area that has long summers it is best to start growing unicorn plants indoors first. If growing the plant outdoors then sow unicorn plant seeds at a depth of 6 mm after the last frost of spring. They can grow in either a sunny or partially shaded area of the garden, but require good drainage. Ideally grow unicorn plants in rich soils.
When growing Martynia Plants indoors first then start about 7 or 8 weeks in advance, they typically take about three weeks to germinate at 21 to 24 degrees centigrade. They should be transplanted into the garden in spring about a week after the last possible chance of frost at a spacing of 30 cm.
Unicorn plants and other Martynia members look after themselves and are able to tolerate dry conditions so regular watering is not required.
