Why sapodilla flowers can't set fruit? zone 9b (Bay Area)

[Si Duong]

I got a Makok Sapodilla in ground for 3 years and around 4 feet tall, looks very healthy. 

Every year it has a lot of flowers and never set fruit even I try to hand pollinated too.  Please help.

Could have some thing to do with humidity. Also are you sure your tree is grafted?
Check and make sure there is a graft union. Sapodilla from seed take longer. Mulch is
a great idea and lots of water. I never hand pollinate and also get fruit consistently in
humid Florida.

I can across this video the other day.  Try this Si.

There's a video recently demonstrating squeezing of the flowers to pollinate. It may be what Bhkkatemoya posted.

Humidity is exactly what I thought also but how come the people in the Los Angeles area or San Diego have fruits set no problem?

I know for sure my plant is grafted. I got 2" mulch around the trunk and I give it plenty of water.

Thanks for your Video.  I will try this method may be it will work because I always wait the flower open all the way and I see the pollen kind of brown may be the dryness in California weather.

My Alano set fruit last year in the East Bay, but it was right next to a Silas Wood so they may have cross pollinated (not that it is necessary, but it might have helped).  The fruit held for many months until it disappeared one day, but I think letting a young tree hold the fruit may have been the reason it died several months later.

I heard so many times about the young plant will died when holding fruit too early and my plant has died that way before too. 

What part of East Bay are you located?

Hand pollination doesn't sound too good. I am thinking to plant a whole row of sapodillas. I already have 4 atemoya trees. I don't like the idea of having to hand pollinating them as well. Maybe having multiple tree might help. We shall see.

SAPODILLA
Flowers are bisexual and may require insect visitation to set fruit. Flowers produce nectar.

I would agree too.  I have an Alano that fruited this year. There isn't another flowering/fruiting sapodilla for at least a half mile around, maybe over a mile.

[achetadomestica]

I notice ants are always attracted to the sapodillas when flowering? Long lines of ants all over the branches.
I am curious if it is the same in California? It seems like California has more issues with fruit setting then
Florida? I am still inclined to believe your flowers are drying out because of low humidity. When you consider
where this tree is thriving it seems to be more humid climates?

There are no issues fruiting them in SoCal
Northern California has a fake 10a/b climate
I've eaten hundreds of fruits since June
Alano
Makok
Silas wood are very productive but I heard after 7 yrs production picks up
Haysa is junk


Still have plenty of Silas Wood

I agree. Every year, my tree has tons of flowers, and even more ants, not a single fruit set. My area is very hot and dry.

I don't know why in Southern California has no problem with Sapodilla that mean humidity is not a main issue.  I saw many ants run in and out of my sapodilla but no luck on fruit setting.

I just want to add my experience regarding sapodilla as well.  I am in Southern California.  A few years ago, I had an Alano.  It was small and had tons of flowers every year but no fruit set ever.  About three years ago, I got a Makok.  It's a bout 3-4 feet tall and is currently in a pot in because I have not found a good spot for it.  I keep it in full sun exposure.  It has lots of flower set.  After two years, last year, it has one fruit currently about the size of an egg.  This year, I am more diligent with watering.  It now has 7-8 fruit buds.  I don't pollinate by hand.  I don't know why it behaves this way.  I just want to share my experience.

Wow, your tree is so big.  How old is your tree? Has it ever given any fruit before?

Your sapodilla is big.  Sapodilla grows very slow.  I guess yours must be at least 15 yrs old.  Do you know if it is grafted or seedling?  Did you plant it or previous owner did?  Did you protect it when it was young?  What part of San Jose do you live?

[raimeiken]

same problem here in AZ. Had mine in ground for two years, lots of flowers twice a year and no fruit set. Tried the squeezing method about a month ago, and no success with it either.    Could be a humidity problem?

I got this 15gal size and had a few fruit on it already, but pulled them out. Tree was trucked in from Florida.

My sapodila tree , but in pot
Variety label was torn off , so don’t know the variety

Only some fruits are forming , this is after hand pollination

It’s October already , not sure if they ever rippened

[Pasca]

Jbaqai,

For a tree that is in pot, your tree looks so healthy and green.  What and how often do you fertilize your tree?
