We have a container orange tree .Its all most 3 years old .We live in the north and so in winter we bring it in and when its warm we leave it outside .
Its gotten quite big and we replanted it just this past summer to a larger pot .Its very tall at least 5 feet now .
The problem is I cannot find out about how to care for it anywhere online .

Its 5 feet has green nice leaves but now they are starting to come off a lot .If you just touch it they fall off .
Its not producing flowers or oranges yet .
I have it planted in a huge pot with citrus dirt we got at a nursery.

We don't know why or what to do .I try and water it but I know over watering is also bad .

Can anyone help me ?
Thanks

How recently did you bring it indoors? Sometimes the shock from much lower light indoors can cause the leaves to fall. If you have not done so before, next time you should slowly acclimate the plant to less light before bringing it indoors.

Two questions:
1. Is the trees' foliage placed where it receives direct sunlight for a good part of the day?

2. What is the temperature of the root zone?

Many container citrus growers have and use a soil thermometer. However, because the curtain is not fully open, much of my concern is already answered. For a container tree, when the leaves are in full sun and the potting soil is at or below 58-60F a tree will commonly drop all or most of its leaves due to WLD (Winter Leaf Drop). If you interested knowing more about WLD use the search function on this forum to learn about it. - Millet (747-)

When will my tree produce flowers and or fruit ?That is what gets me worried .Other than the leaves falling do you think its doing ok ?

You write that your orange tree is now 3 years old. If the tree was started from seed it should begin to flower and fruit when the tree is between 8 to 10 years old. If the tree is a grafted tree it should be blooming and fruiting now. - Millet (747-)

We got the orange tree at the Grove House for Florida Natural juices.
It was I guess like a starter maybe .It was more than just a seed but it was small and in a box .
I just checked their web site and I don't see this any more .
I cannot seem to find the original box right now .
So more than a seed but not a full blown plant .
I am not sure if you are allowed to post pictures if so I could take a picture to show what it looks like .
To me it looks like a small tree its not full its kind of skinny .

There are only 3 types of orange trees. 1). Grown from seed, 2). A grafted tree, 3). A tree rooted from a piece of a mature branch. Trees number two and three should be presently blooming and fruiting. If the tree is a grafted tree you should see a scar (line) where the scion (upper part of the tree) and the root stock were grafted together. This will be 2-4 inches above the soil line. You can also post a picture of the tree's lower trunk, and the membership will be able to tell you if the tree is grafted or not. - Millet (767-)

I took a couple pictures

I suppose it was from a seed it was sort of sappling when bought it

I would say that it looks like a young tree grown from seed in its full juvenile stage!

So it looks good ? Like it suppose to ?
