Use a sharp knife and slice a thin heel from the crown. Place in water for 2 or 3 hours, then re-move and dust with sulfur before placing in moist sand. Keep partially shaded and moist. After cuttings have taken root, move into 3 or 4-inch pots. They should be ready to transplant into the garden in about 5 to 7 weeks.
Good seed is necessary to produce good plants.
Hand pollination is generally preferred. Use a good, loose potting soil, firming it down into flats or pots with a wooden block and then moisten before sowing the seed. Keep moist and shaded until seeds germinate, then remove shade. August sown seed produces seed-lings that can be wintered over in a cold frame and given a permanent place in the garden the following spring.
