Put up stakes and support them.

The fruit is not Meyer, perhaps from the rootstock whose fruit is often grapefruit sized.

i was going to say the same thing, the fruit is the wrong shape and wrong size for Meyers.

There's one stem in the middle with smaller less luxuriant foliage. I think that's the Meyer. The big vigorous leaves and grapefruit type fruit have got to be the rootstock.

Don't worry too much about it citrus limbs are FAR more flexible than other fruit trees, as to the fruit, Meyers tend to produce a handful very large fruit the first year or two of production, then the fruit gets more prolific and smaller.

I can't see the leaves well enough to tell if they are correct for Meyers or not.

Thank You!!

Here is a listing of rootstocks. Shaddocks are big like grapefruit.

Never had my Meyer do that. I did have it growing in a half barrel for many years before getting tired of that. So i planted it in ground. After more years it suddenly sent up long thick branches..nothing like the older potted plants frame. The fruit though were Meyers.

Wait and see what those big boys become. If they are rootstalk, cut them off asap.

I’m not familiar with what rootstalk are and why do you have to cut them off asap?

I saw the list that sautesmom provided above but I still do not know what that is. I am an amateur just growing a lemon tree in my back yard. My neighbor has grapefruit and tangerine trees about 40 feet away.

I live around the Houston, TX area and I bought this small Meyer lemon tree 4 years ago from Lowe’s. It produced 3 large grapefruit size lemons the first year and has not produced since. I thought that it died two years ago in a freeze. But once I nursed it to health it looks like it has some different kinds of leaves on one side. This year it has more that a dozen lemons. One has already broken off and a few of the others look like they are going to do the same.

Better to ...take it to the trash and get a true Meyers. Unless,you like the (non) Meyer lemons it's giving you. At the least,it's hardier to cold,you know that.

But, as somebody who has grown fruit trees from seeds or of unknown grafts..you can waste years hoping they will get better..and they almost never do. Why I say,get a Meyer and take out the imposter. You'll thank me one day- wink.

It looks like we have several topics going on here, first off on root stocks, I don't know the popular California root stocks particularly well, as I live on the gulf coast and am more familiar with the Florida root stocks. California soils tend to be calcareous where gulf coast / Florida soils tend to be acidic, therefore the use of different root stocks.

If you look at the base of the tree you will likely see a graft line, most Meyers sold in citrus growing region is grafted onto some hopefully regionally appropriate root stock. Limbs from above the graft will be Meyers (if the tree was labelled correctly), and from below the graft line will be root stock, which should be removed. It should be noted that around half of Meyers lemon trees sold in the US are not grafted, though these are primarily ones that are sold outside of the citrus growing belt. Root stock will grow if allowed develop will take over a tree, this is why it is important to cut off any shoots growing from below the graft line.

So far from the single photo I see nothing that would make me conclusively think what you have is anything other than Meyers, even if it was grown from seed as Meyers has a very high rate of being true to type when seed grown.

If you post a close up photo of the first 6-12 inches of the trunk we may be able to help you spot the graft line, if there is one.

How interesting, I did not know Meyers came true thanks!

Oops, sorry, just double checked, Meyers is one of the few low pollen citrus that don't grow true to type

https://www.houzz.com/user/sautesmom thanks for your comment on this topic and list of root stock. I have a commercially grown Meyer that i purchased at a local nursery . A couple of winters ago i left it out unprotected for too long and the entire top of the plant died back . the following spring it grew back from root stock and now produces huge almost grapefruit size fruit that are somewhat hard and dry. the leaves are larger then meyer leaves and stems have thorns. Below are two photos , one with normal size (somewhat large) lemon for size comparison. At first I thought i may have a rough lemon , but now think it may be the Shaddock you mentioned . Any citrus enthusiasts or experts able to help me ID this variety ? Any help would be much appreciated as this mystery has bugged me for years. thanks in advance !
