How to care: Two trees for increase the chance of pollination grow the trees, prune once a year, fertilize 4 time a year (when the tree is young more nitrogen), cover the soil in mulch, add humus and organic matter.
What is the best way to start growing? Plant / Cutting conditions / Air layering / Seeds
Is it necessary to graft or use vegetative reproduction? Yes, it’s not hard to start by seeds but better grafted tree can be ensure the quality of the fruits like: taste, amount of seeds, size of the fruits, less years to bear fruits, and longer season, also possible to graft to different cultivars on the same tree also another option to graft two different species of Annona trees
Difficulties/Problems with growing: Low amount of fruit caused by the difference blooming hours between flower for male and female trees
Planting season: Spring in hardiness zone 10b, spring to summer in hardiness zone 11a, spring to autumn in hardiness zone 11b, 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.
Pruning season: Winter and also possible to prune after the fruits
How to prune: Cut the outer branch, make the branches grow into each other in high density, when grow to cultivars or species better to let them grow into each other it’s increase the amount of fruits, when takes leaves by hand for the base, might grow stem in this location so it’s something to consider.

Is it possible to grow indoor as houseplant? No
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.
