I bought a Black Pearl Wax Apple tree to grow in the Bay Area in California. This fruit is popular in tropical areas of Asia, but it virtually impossible to find in supermarkets outside of Asia. I've scoured Google for how to grow Wax Apple, but could not find any useful information.

1. What kind of soil does it like?
2. Is it self-fruitful or do I need to cross-pollinate?
3. Does it like to be pruned?
4. Is it deciduous and can it withstand winters of 45 degrees Fahrenheit at night?
5. How much light does it prefer?

I grow Wax Jambu in the Bay Area. They freeze outside in the winter, so I grow mine as a house plant in the sunniest window at my house. It does great. A big crop of fruit every year. You don't want to let it dry out too much. Down in Southern California, I've seen them thrive outdoors (in San Diego), but I don't think it will work so well outdoors in the Bay Area, unless you live in a microclimate that is especially warm. It doesn't get too big in the pot indoors. I think indoors, and in a 5 gallon, or so, container, it will stay smallish. Yet it has grown nearly to the ceiling in just a few years. We'll see what happens in the future.

Trying to decipher this.

**It may need winter protection in your area.**

**The plant should be in a five gallon pot until 12 inches tall, at which time it can be planted in the ground.**

**The plant needs a full day of sun.**

**This plant is evergreen. If the leaves fall, you have a problem.**

**This plant does not have special soil requirements, and any healthy soil is fine.**

I would trust this information, because, as a grower, they know the best methods of growing a healthy looking plant (so people will buy it).
