Varieties of Custard Apples
There are two main varieties of Custard Apples, the Pinks Mammoth (or Hillary White) and the African Pride. Both are sweet, juicy and full of flavour.
Pinks Mammoth: Pinks Mammoth are large super sweet fruit which some growers hand pollinate at flowering to improve fruit shape. These trees can produce fruit weighing as much as 3kg. It is from Australia.
African Prides: It is an artificial hybrid produced from a cross between the plants Sugar Apple (Annona squamosa) and Cherimoya (Annona cherimola). It is also known by the name Pineapple Sugar Apple.African Prides are a medium sized, well shaped 500g to 800g fruit that sets well on the tree.
The other varieties are:
Planting Custard Apple Tree
Grow in Garden
They can withstand any type of soil. But the only catch is that they cannot tolerate water stagnation.
So better use a well-draining mixture for avoiding this problem.
Prepare a mixture of manure, compost, sand(if available) Ratio can be 40:20:20(Soil: Sand: Manure)
Choose a site that receives good sunlight and have good air flow.
Also avoid places where you have grown brinjal, capsicum, tomatoes and potatoes to avoid infection with bacterial wilt.
I already stated that these require a well-draining base. So let’s start making one.
Dig up a hole that is 60x60x60 cm
Leave the hole dry up in the sun light for some days(4 days). This is to sterilize the hole.
Now fill the hole with the mix that you have made.
Getting the plant
This must be the first step actually but people are so focused on getting a plant and planting it they dismiss all the other things that could boost up the process.
Grow custard apple from seeds
Get the seeds from the fruit you buy
Soak it up in water for a whole day(24 hours)
Next day you can see the seeds that are potent will be drowned in water
The ones that are floating are of no use. You can throw it away.
You can sow them directly in Soil (pots or in ground).
For this make a hole using your finger and drop the seed in and water it daily such that the soil is not dry
Sow a minimum of 4 seeds out of which 2 may germinate.
You can even keep them in wet tissue paper and keep them in a zip lock bag to germinate
Whatever method you try it takes 2-4 weeks to germinate
Grow Custard Apple from cuttings
There is a method knows as Air-Layering where a healthy branch is selected from a mature tree.
Then an air-tight bag of wet grow medium is tied around this branch which pushes it to root. Now this branch is cut and is planted separately. This reduces the time we wait for fruiting.
Custard Apple Tree Care
Just like members of the malus domestica family, the Custard apple tree requires full sunlight. This should be no surprise considering that this tree is at home in tropical climates. You’re going to want to plant this tree in an area of your yard that has at least 6 to 8 hours of sunlight everyday.
With that said, this tree can withstand partial shade.
The Custard apple tree is only mildly drought-tolerant. This tree requires 700 mm of annual rainfall a year in order to stay healthy. If this tree experiences a considerable drought, it can bear fruit inconsistently for a season or two.
Pruning the Custard apple tree is a bit more intensive than pruning your standard malus domestica. Custard apples are very heavy fruit and can weigh down the branches of this tree. You want to trim back the branches to establish strength during the tree’s dormant period. This operation can be a little intense if it involves removing up to two-thirds of the growth from the previous year.
Like all other plants they require NPK (Nitrogen, Phosphorous, Potassium). They require them in the ratio of 2:1:1. So let us see the organic fertilizer sources for them
The best source for all the nutrients are the cow dung, goat dung and other manure
You can also use vermicompost or any other compost as they have high Nitrogen content in them.
Add some panchagavya to soil. Along with the nutrients it has, it also helps in multiplication of the beneficial microbes that will help in fixing the essential nutrients in soil
For potassium you can use banana peels, wood ash
For phosphorus you can get Fish Amino Acid – Meen Amilam which also supplies potassium and nitrogen
You can also add powered remaining fish bones and chicken bones. These too have phosphorous
Add Neem or groundnut cake this promotes nitrogen
Feed them monthly once or twice.
As the plant grows so does its need for nutrients. So increase the amount of fertilizers as the tree grows. It will be completely matured in 5 years.

The custard apple is heavily attacked by the chalcid fly. Many if not all of the fruits on a tree may be mummified before maturity. In India, the ripening fruits must be covered with bags or nets to avoid damage from fruit bats.
