Sounds like water sprouts, but without photos, it would be just a guess. If you could upload photos of the entire tree, and closer photos of the branch you're referring to, that would be very helpful for us to be able to help you :-)

Large leaves on orange trees seem to be a common "complaint" lately (facebook).
I've noticed that my Moro will occasionally grow an extra large leaf here or there, but I don't
think of it as a problem. I figure a couple larger leaves are a boon during the glum Winter months.

As Patty mentioned, pics please :-)

I have attached a photo showing the full view, and will attach second photo in next post.
As you can see, there are various shoots of this growth coming from some of the pruned branches.
Thanks for your interest :-)

and the second photo, showing the growth from the top of the pruned branch.

(sorry, but not sure how to upload more than one photo to a single post)

If the branches are coming up from the bottom, they may be from the rootstock. Is your citrus grafted or did you grow it from seed?

It doesn't look like from the photo that this branch is coming from below the graft line, but as lgteacher has mentioned, do check to make sure. If it is, it would then be a rootstock shoot that should be trimmed. If not, don't worry, just some new growth that will settle down.

Thanks for your replies. No, it isn't coming from below the graft line, which is one reason why this is puzzling. We'll wait and see :-)

Just a vigorous flush, then idnobaran. If this branch really takes off, and starts growing straight up, it's simply a water sprout. You can prune it back to the edge of the canopy, and it will eventually settle down. Not unusual behavior by citrus to send up water sprouts. If they cause an imbalance to the overall canopy, you can prune the completely back. There is a misconception that these water sprouts do not provide fruit. They do, but at the tips (as citrus produce fruit at the tips), and since they are not very sturdy, they can end up breaking off. So, it is best to prune them back at least to the edge of the canopy, or, if creating cross branching or an uneven canopy, simply prune them back to the branch they emanate from.

many thanks Patty for that information - I didn't know all that about watershoots so I have learnt something new :-) We'll do that and see how it goes.
