According to Purdue University the cherimoya tree is a native to Colombia, Ecuador and Bolivia. This tree is actually a fruit-producing tree. In country like United States, cherimoya tree can only be grown outdoors in Hawaii, California and Florida or anywhere within USDA plant hardiness zones nine and ten. In other locations the cherimoya tree can be grown indoors in a pot. The cherimoya tree really grows well from seeds, though the fruit from seed-grown cherimoya trees is not as large or abundant as the once from other propagation methods.
Step one: Get a large bowl and fill it half with water and then place the cherimoya seeds into it. Press the cherimoya seeds down until they are all wet. You need to set the bowl aside and let it rest for about 4 days.
Step two: Look at the bowl of water and then scoop out any floating cherimoya seeds with your hand. Throw away these seeds since they are not viable. Scoop out the remaining cherimoya seeds on the bottom of the bowl and then set them on a paper towel before throwing away the water.
Step three: Fill five to six inch-deep plant pots with a mixture of one part peat and one part course sand. Make sure you mix the two well, until they are really combined. Each of the pot should be at least ¾ full with the soil mixture.
Step four: You have to place one cherimoya seed into the center of each pot and then cover them with one inch of the soil mixture. You can add water to each of the pot to settle the soil around the seed.
Step five: You need to set the pots in an indoor location that maintains a temperature of between 64.5 and 77 degrees Fahrenheit. Make sure you water the pots as needed to keep the soil from drying out. The cherimoya seeds will actually germinate in approximately 3 to 5 weeks.
Step six: Transplant the seedlings into eighteen inch-deep pots that is filled with potting soil once they reach about three inches in height. You need to grow them under bright, sheltered conditions until they are ready for transplant into a permanent outdoor growing location.
