If you only want your fruits to get the size of apples, that should do it.  If you want big fruits, there should not be more than one fruit in the foreground of each of those pictures.

If you want big and really tasty fruits, and a tree that continues to be healthy, than there should only be one fruit per each branch with a dozen or so big leaves.

The problem of finding flowers only at the same sexual stage, and the problem of going more than one day between stages, occur during overly cool weather.

Thanks Har. Going to do some thinning. Will limit any new hand pollination to branches higher up, some of which don't have much or any fruit yet.

The ubiquitous Staphylinae beetles, should probably work as Rollinia pollinators.

In south Florida, Nitidulid beetles pollinate Rollinia and true Annona species.  Bigger beetles and bull ants appear to pollinate Guanabanus species [soursop and related species].  Carrion flies pollinate dark-red-petalled Asimina species.

Encourage presence of Nitidulid beetles, which are only a couple of millimeters long, by allowing fruits, especially citrus, to to be available to the beetles as the fruits rot on the ground.

I have never seen, nor heard of, any species of bee pollinating any Annonaceae.

Mine has been self-pruning. I would think the tree would abort a good portion of those. But could be cultivar dependent.

This is how it looks all over the underside of the tree.





Can anyone chime in about if this amount of fruit so close to each other is okay? Is thinning needed, or should I go for more? As it stands, still pollinating. Has become a ritual.

Jeff, what cultivar are you growing?  How big are the fruits? Would like to get a few  seeds from you.

that amount of fruit is fine just remember to be consistent about watering

Are there any known cultivars of Rollinia?

Thanks DB and Cookie.

Glad I don't have to figure out everything on my own.

It's a seedling from Noel's rollinia, which produces the large fruits. There seem to be 2 common cultivars / races here in FL: the small fruited / productive but not as good tasting and the large fruited one. Then there are a couple of hybrids that Har made.

Replied on this thread back in March when I had given up hope on dismal fruit set from past 2 years, and was gonna cut my rollinia down. Then spring rolled into summer and she busted in flowers and set a bunch of fruit. Several fruit the size of a babies head! First big one should be ready tomorrow or Friday to pick. Had the first, a small one, yesterday and was delicious. Ironically Har had come out here to evaluate my yard just before she bloomed and put in practice the things he mentioned so I guess they worked lol

Good job FisherKing!

So hand pollination worked very well:











Does anyone have an idea whether this is the large variety or small?

If it is a seedling, no one can recognize it as a variety already existing before this new variety was born!  You name it, if you and others believe it is unusual and special.

it's good, but not great. probably should've thinned the fruit some. several fruit are on each branch that is fruiting, so probably depleted the tree a bit, resulting in blander fruits.
