It's garbage rootstock growth. Cut it off the tree before you lose the clementine part. You have multiple branches that need to be cut off.

Yes,you could have two types of citrus on one tree; but the trifoliate rootstock would never produce an edible fruit. More than that, the rootstock is more vigorous and will soon overshadow/weaken/kill your clementine. Cut it off now, before it gets worse. BTW, I see a tree tag... does it say what the rootstock is?

John Since when does a citrus tree propagator put the root stock on its tag. Four winds wouldn't tell me even after 2 of us requested than knowledge.

The good ones do. Harris, brite leaf

Four winds seems scared of releasing "proprietary" information.

Really i think they lie about all of the rootstocks being "true dwarf" as they advertise.

I still like them but they are no longer my #1 go to.

Thanks for ID, both offending rootstock limbs have been removed.

When do potted clementines usually flower?

A grafted tree that looks like yours should produce some fruit in the next 2 years.

Agree with pip that the good ones should have the rootstock labeled. My Meyer Lemon and White Grapefruit were both tagged clearly as on Carrizo Citrange and Volkamer Lemon respectively. Your rootstock might be poncirus trifoliata but that's really just a guess as many of its hybrids have trifoliate leaves also. Agree that you should keep pruning the rootstock growth off.

Poncirus is a species not a variety. For example flying dragon is poncirus.

Hi Rick....Have you checked to see what that white substance is underneath the bottom leaf in the first pic, the first leaf up from the trifoliate branch?

Pluto is now up to being a planet and John you are correct.

My bad for not typing trifoliata but either way poncirus trifoliata is not a single variety/clone.

Hi, the white stuff is probably sevendust. I was using it for the picture below, is this a bug problem?

It would be nice to have a dual citrus... But they keep using C-35! (FYI, my rootstock, its apparently trioflate x sweet)
