Difficulties/Problems with growing:
Low amount of fruit caused by the difference blooming hours between flower for male and female trees, some tree can grow a lot of year without any fruits
Spring in hardiness zone 10b, spring to summer in hardiness zone 11a, spring to autumn in hardiness zone 11ab, all year in hardiness zone 12+
How to plant:
Dig hole bigger 50% more than the roots ball, add to the hole, organic matter, dead leaves and hummus put back some soil and mix it, after this put the tree cover lightly but strong enough that won’t fall put support for the tree if needed, if the tree is not stable consider to prune, water it twice in the first day and every day for two weeks.

Size of the plant?
4-10 m, 12-30 feet
Growth speed in optimal condition:
Medium growing / fast growing and in the tropical grow or with enough fertilizer will grow faster
Average amount of water to big amount of water

Full Sun (better in full sun the tree will yield more fruits) / Half Shade
Is it possible to grow indoor as houseplant?
Growing is also possible in a planter, flowerpot or containers:
Need to keep the tree small to grow it as shrub or as bonsai, consider to graft two cultivars on the same tree, the container need to be 20% bigger than the root ball until the plant arrive to the right container, wouldn’t recommend to start from big container on small tree in this method it’s care for the viability of the soil, grow with the tree will be the best method, every few years to switch the soil with big container there is no need to switch all just switch part and cut some of the roots ball (can switch from the side and the top, fertilizer four time a year, making enough holes in the container for good drainage also choosing soil for container important an option it’s to use peat soil, perlite and organic matter, need to add hummus few time a year, water it regularly and when put bottom for the pot be aware not to let the water sit there more than one day and do not over water it’s destroy the soil and the roots.

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
Better in different pots – because need to graft it after and some won’t establish, better to choose the best to transplant to the real location
