Author Topic: Soursop Pollination (Read 19660 times)

Hi,

I purchased a 7 gallon Soursop from TT last year. It has grew a lot since last purchase. Earlier this year, it has one flower, but didn't set fruit. I put it down in ground inside my greenhouse last month, and now there are many flowers. Two of the flowers already opened the petals fell off. I don't expect these two flowers to set fruit because there was no other flower to pollinate.

My question is, does soursop need hand pollination in order to set fruit? I see many ants around the flower. Also, can the pollen be collected and kept in refrigerator to pollinate other flower later on?

Thanks for all advice!!!

Tuan

Did the flower fall off the tree or did it leave the base on the tree?

I read an interesting article that stated that the flower first opens as female and is receptive to pollination for 24 - 36 hours,and then it becomes
male. The article also stated that the male's pollen is viable for just a few hours and can't be used on the same flower that was previously
female. I have the article on my computer at home and will try to post a link tonight. I'm sure others with more experience will add to the discussion.

Thanks Michael and From the Sea,

The flower base is still remain on the tree. The first flower still has its base for a week, but it haven't got any bigger. I assume it wasn't pollinate.

Thanks again

I have had the flower base stay on the tree and not grow for months, and then a fruit starts growing when the weather warms.

To answer your initial question hand pollination isn't usually required but just about always results in better and more fruit set. Annonas have a naturally low rate of pollination compared to flowers produced, something like 3%, so mechanical pollination can improve those numbers. Google cherimoya hand pollination, the process should be very similar and should answer your question about storing pollen.

The question are:

Is Soursop self-fertile or not?

If yes, does it need hand-pollination?

The two things are different....A. cherymoya likes hand pollination, but big tree, not in pot, will produce also without hand pollination...

After 3 months, it had developed to this!

Hi Tuan,
I will start checking Hi/Lo temperature in your city. Are you grow them in a green house?
I'm in San Diego and everything is in a stand till mode. Nothing is growing except weeds.

A question for everybody, what annona species that will take Soursop's pollent?
Thanks

Hi NewMoon,
Yes all my plants are in greenhouse. Half of them in containers, and other half in ground inside the greenhouse. So far, they doing very well. I maintain temperature around 60 degree during winter time.

which kind did you purchase from them? Thanks. Was it the 7 gallon seedling?

Tuantropical · « **Reply #11 on:** January 25, 2016, 12:25:07 AM »

It was the 7gl grafted, homestead.

Mine has set fruit without hand pollination. This was the first year with blossoms.

Hi Tuan, nice soursop tree. Slightly off topic but what is that nice citrus to the side of your tree?

WGphil · « **Reply #14 on:** January 25, 2016, 02:29:33 PM »

My girlfriend just bought a grafted miami soursop. Thanks for the info.

Can anyone tell me which anonna is better for smaller yards. Is Ilama a bigger tree than an atemoya or are sugar apples bigger than custard apples. Hard to find that info to decide what fits best where.

Which are the smaller types, plant not fruit, in that family.

sugar apples are smallest trees of those 4. Having said that, I don't see why atemoya or ilama couldn't be pruned to maintain a small space.

Here is a good place to start: https://hort.purdue.edu/newcrop/morton/index.html You can scroll down to annonacae and click on the different annona members

Thanks a lot.

Hi Tuan, soursop are self-fertile. Thus, no need for hand pollination.

How much did u buy your soursop? What variety is it? Any new photos of your soursop?

Tuantropical · « **Reply #18 on:** January 28, 2016, 03:08:23 PM »

To BahanaDan: The citrus in the background is a blood orange. It was loaded with fruit. We ate most of it, only two left.
To Gozp: I believed I got a 7 gallon grafted Homestead. It was around $100 from Top Tropical. Here is a picture when I just received it in June 2014.

Tuantropical · « **Reply #19 on:** January 28, 2016, 03:17:36 PM »

It grew quite a bit.

Thanks Gozp & Paradise!

Very impressive plants Tuan and I'm Virginia no less. Couple questions lol: what do you feed them with to get them looking so nice? Is that a sapodilla in the second photo in a pot? I may be mistaking a citrus' leaves for it. Is that a grapefruit or pommelo in the third and fourth photos and if so what kind? Are most of your plants, citrus especially, potted and what mix do you mainly use? Have you also experienced the delayed/non-existent bloom on your mangoes that a lot of us have, or have you been able to control conditions in your green house such that they were able to bloom normally? Anything special for the pineapple? That's it I think lol, and again your stuff really does look great

hi Dan,
Thanks for the compliment. I mostly feed whatever organic fertilizer I can find at HomeDepot plus compost tea during summer time. I grow them organically.
It is a Pommelo. I don't know what kind, but is really big. Not very sweet though.
I pot all my plants with 5-1-1 mix.
The set my Greenhouse Thermostat to 62 degree. Therefore, temperature in the greenhouse doesn't get lower than 60 degree.
I have problem with mango bloom early as well. When when bloom early and in the greenhouse, they don't set fruit, except for my Pickering mango. Pickering seems to set fruit easily and not being picky.
I don't do anything special to the pineapple. It just grows in there and set fruit. I think pineapple is a very low maintenance kind of plant.

Thanks Dan

Here is a photo of update Sourshop fruit and mango.
