I have a ten year old containerized orange tree (variety unknown) that won't flower. Tips?????

In winter when I bring it indoors it loses all of its leaves, but survives and when I put it outdoors in the summer it bursts into leaf again. This summer it's foliage is excellent. But it just refuses to flower! It is 2m in height and it's trunk is approx. 5cm dia. 10L pot.

It may need fertilizer. Someone said it may need to be repotted. If you can, check the roots to see if the plant is pot bound. Also check out the holes in the bottom of the pot to see if roots are coming out of the holes. If you see roots, repot the plant.



If that isn't it, I would fertilize it. Citrus plants need fertilizer (NPK) to produce flowers and to set fruit. If it lacks fertilizer, it will not carry out those functions and may just continue to produce vegetatively.



Hope this helps!

Reply:I have a lemon tree and it calls for acidic fertilizer. It may be just what your plant needs :)
Reply:Put it in the ground and wait another 15 yrs. and you may get tons of fruit.
Reply:This is a long time in the same pot and it might be root bound. Repot it to a larger pot and fertilize it. If you don't want a larger pot, wait until the end of the season and take it out of the pot and trim back some of the roots and repot it using some fresh potting soil.
Reply:I would check with a knowledgeable person at your cooperative extension service, or find a good book on the subject. Possibly at your local nursery or at Amazon.com; the soil may need to be changed, as flowering requires alot of nutrients from the tree in order for it to fruit. This way you would know exactly what to do %26amp; when to do it! I'm not so sure you will find an expert on the subject here, but at least you got me thinking! sorry I can't be a whole lot of help this time, dear.
Reply:Possibly it needs to be repotted into a larger pot. If the roots are too crowded, it won't flower.
Reply:Depending on what zone you live in you could leave it outdoors for the winter if it's not too cold. Change the soil, place it in a slightly larger container, don't disturb the root ball just add soil around the edges and top and bottom of the root ball. I would use a citrus fertalizer in early spring, not in the middle of the summer. They don't like very much water so be sure you are not over watering it.
Reply:maybe water it
