Well I would think the fact that it is growing more often then it used to is a good thing and would continue to do what you have been. Not knowing the strength of your fertilizer I cant comment on it being too much but if it is the plant will let you know.

It looks elongated telling me it was growth from being fertilized with too little direct sun. That kind of growth is different from summer growth and more susceptible to spider mites. Just watch for them and it should be fine.

Mike is exactly right and it is what I try to avoid unsuccessfully every winter. I agree about watching it for pests, but it should be ok. Sometimes, if too spindly, I’ll trim it off once the tree goes outside.

Ah ok so no fertilize at all for the winter? I’ve only been fertilizing every 3 weeks or so. And unfortunately where they are now is the sunniest place in my house so that can’t be changed. Spider mites seem to be gone now.. big change compared to last year but scales seem to have developed on my satsuma mandarin since a couple months ago. The Yuzu doesn’t have them for some reason even though the two trees are next to each other

It’s a very very fine line with me when it comes to fertilizer. Most of mine don’t need anything at all and show no ill-effects if there is little direct sunlight. Once I see them awake with longer days and more sun I will fertilize. That is usually right before they go outside. I hate spindly weak growth very desirable to pests and not to me therefore your reason for scale after the mites

I cannot wait to take mine out. I’ll probably end up trimming those weak growths, but not till outside or the tree will just sprout again.

Hmm so that explains why my 3 year old citrus is very tall yet weak stems. I will significantly lower the dose of fertilizer next time.

Most all my citrus are starting to put on growth. Much of it has to do with the longer day lengths which the citrus is responding to. But very lanky growth can be caused by low light and too much fert.
