Plant / Seed / Vegetative reproduction – propagating by cutting better to start in the early spring or with temperature of 21-25C (70-77F), requirements: moist soil, high humidity, peat soil, hormone for root growth, highly recommend to use green house (or small plastic box with holes) it will take few weeks for the first root
Is it necessary to graft or use vegetative reproduction? No, but it’s not hard to start by cutting and also not hard to start by seeds
Difficulties or problems when growing: ?
Planting season: Spring to summer in hardiness zone 7-10b, spring to autumn in hardiness zone 11, all year in hardiness zone 12+
How to plant: Planting in bigger hole and put organic matter, chopped dead leaves and humus, put the plant and cover it lightly and keep it moist for few weeks until the plant establish
Pests and diseases: Aphids, spider mites, mealy bugs

Water requirement: Average amount of water / Big amount of water
Light conditions in optimal condition for growing: Full sun / Half shade
Is it possible to grow indoor as houseplant? No
Growing is also possible in a planter /flowerpot / containers: Yes, when growing in containers need to choose container that 100-200% bigger than the roots ball or possible to grow it in small but cut the roots when planting, use potting mix or peat soil with perlite, but after few years drainage of the soil not function the same so need to change it to new soil, when growing in container need to add organic matter and fertilizer at least once a year.

Saving seeds until sowing: Dry and dark location, keep it room temperature
Sowing season: Spring will be better for the tree but possible in summer, and in hardiness zone 12+ possible all year
How to plant: Plant in soil that will keep the water and don’t let it dry, full sun
Planting spacing: Better in different pots – because need to graft it after and some won’t establish, 2*1m (6*3 feet)
Depth of Sowing: 1cm (0.5 inch)
Conditions for seeds germinate: Moist soil, sunny location, water regularly and don’t let it dry
Watering requires for Seeds: Average amount of water
