Does anyone have any information regarding Soursop (Guyabano) or Sweetsop (Sugar Apple)?

I'd like to try to grow some in pots. Are they suited for pots? How long will they take to fruit from seed? How big do the trees get? Any info would be appreciated. Thanks.

Soursop (guanábana), Annona muricata, is an ultratropical, so you need to keep it warmer than 50°F or it may be damaged. We grow it in a large container in a greenhouse, and it started flowering and fruiting when perhaps 8 feet or more tall, with a stem perhaps 2 inches in diameter. It's mostly cauliflorous (bearing fruit on the trunk, rather than the branch tips). I'd think this one would be difficult in a house, but in a greenhouse, with maybe a 10-gallon pot, you might be able to produce fruit.

Sweetsop (anón, Annona squamosa) is substantially more cold-hardy, being damaged a bit below freezing. So I'd call it tropical, rather than ultratropical. It's a much more shrub-like plant, and will bear younger (3 years?) and smaller, from seed. Many of these come fairly true-to-type from seed, so if the fruit the seeds came from was good, your chances of getting a good tree are reasonable. I'd think a 5-gallon pot would be adequate here, to produce a fruiting tree.

Thanks. I think I am going to give these a try as soon as I can find some seeds or fruit. I like that it doesn't get very big and fruits fairly quickly from seed. I remember eating these when I was younger so it'd be nice to have some again.

If you do, try to plant the seeds right out of the fruit, still wet. If you dry them out even for a few days, they may die, or they may enter a really tough dormancy to break. GA soaks may sometimes help, but not always. On the other hand, planted fresh, they generally germinate quickly and easily.

How do they take to transplanting? Should I go straight to a 5 gallon pot or will they be ok starting in a small pot and then transfer when they get bigger?

I've not transplanted many, but I'm not aware of any special problems. I'd go for the smaller pot for a while, first.

The more hardy subtropical Annona species types can be used as rootstocks for their less hardy relatives.

Riversendnursery.com is a nursery that grows that sugar apple here locally. They sell fresh fruit and plants also, they have a large variety of tropicals if that's what your tring to grow.
