Guanabana flower?

[NewGen]

This 6'er has been in a pot outdoor since March 2015. Temps at night have been mid to high 40s the last couple weeks. This morning I noticed  few cold-damaged leaves, so I moved it to the greenhouse. During the move I saw this!

Wow! That's wonderful. You planted this from seed right? How many years?

[NewGen]

This was not from seed. Got the tree about 2 years ago, 4feet tall at that time.
Thanks

awesome! can't wait for mine to bloom. they sure have some interesting, thick flower petals.

very nice, I'm trying to fruit one in a greenhouse too, well only during winter it lives in the greenhouse. I also use an air pruning pot.

[NewGen]

Well, I just realized that with just 1 flower, I'm not gonna get any fruit. Don't all annonas need at least 2 for pollination?

Guanabanas usually flower for a couple of years before they set fruit.

I didn't know that. Thanks for  the info. It's  exciting nevertheless.
Thanks,

Turned out  I overlooked 3 other flower buds, so this tree has 4. 😀 There are 3 in this photo.

Do you need to hand-pollinate guanabana?

[NewGen]

I don't think you need to, but I will.

45F outside and in a greenhouse, probably not too many pollinators about.  I had a fruitlet that aborted and I didn't even know about until it was about done, not required in my neck of the woods, at least in the summer.
I think your chance of success is slim heading into winter, but you don't know if you don't try.

[NewGen]

Yeah, trying is part of the fun. I don't expect anything this first year of flowering.

Do you heat the greenhouse?

[NewGen]

Do you heat the greenhouse?

Yes, it  has several fans on timer and usually 1 (sometimes  2) heaters on thermostat. Temp is  maintained  at 60 F.

NewGen,

Have your soursop set fruit successfully? I am so happy and excited to see my newly purchased seedling ( yesterday) has 4 flowers. I never see seedling soursop has flower before. It is about 4 ft tall in one gallon pot. I don't know if I should transfer it to a new , bigger pot now or wait untill the flowers set fruits or drop.

Great job Newgen, maybe next spring you'll get lucky?
