Well, now you have a tree plus an appendage on the side :)

Are you keeping that because you don't want to lose the production?

It sounds like you haven't been too thrilled with the size/flavor of your fruits so far. Is the plant self-fertile, or is there a pollen source near by?

Do you know how old it is? I infer that you've inherited it so I'm guessing you don't know if it is a variety or a seedling.

While you're thinning your feijoas to aid size and quality, perhaps you could do the same with your neighbor's grapes.

Lol - ok so I have a mutant tree.

I left it because that "branch" is nearly the daimeter of the main trunk and I was worried about shocking the poor tree, and also because my dog likes to lay down under there for shade.

It's self fertile as far as I know - I dont' think any of my neighbors have trees but it still sets hundreds of fruits every year. They are all samller than golf ball size and kinda bland, I've noticed that nothing seems to eat them (squirrels, mice, birds ...) and they just fall and rot. Birds LOVE the flowers, but the fruit is kinda useless.

As for age, I'd guess over 10 years. I bought the house about 3 years ago and it was a rental property for about 7 years before that so I assume it was put in by a real owner way back when.

I have to attack his vines weekly to keep them from eating my tree, he's good about pruning it away at the end of the season but while they're growing he just lets them be.

That's a lucky dog to have the shade of a feijoa!

The birds would be instrumental in assuring pollination.

It's probably a seedling with low quality fruit; thinning may not have any effect but we're interested in the results.

My shrub will have to hurry to bloom before July 1.

I think it's usually around Sept or so when I start get ripe fruit drop, I'll try and remember to come back to this thread to say if thinning helped at all. And heck, maybe they're actually really good feijoas and I just don't like them. Part of the problem is size, scooping out the middle just doesn't offer enough payoff to effort so maybe if I get bigger fruit from thining I'll be happier with them.

I have a 20 footer ,fruit tastes great,all slightly bigger than golfballs,and all fruit drops in one weeks time.juiced with booze its a great drink!
