    Default Lemon Tree in big trouble

    Hello all

    I purchased quite an expensive lemon tree a few years ago. It came with lemons on it, but as soon as i brought it inside in the winter, it lost it's leaves and died.

    I decided to give it another go this year a bought a three. Bought one from Aldi in spring. It did really well outside, producing tonnes of foliage, flowers and quite a bit of fruit.

    But having brought it inside (slowly brought it inside, a few hours at a time to acclimatise it), it's now in trouble with pests and lost leaves.

    The first thing I noticed were spider mites a couple of weeks ago.
    All over the place, and a few webs here and there. I sprayed them off with a garden hose which seemed to do the trick. But now I just noticed they're back in force, and since about a week ago the tree is losing a lot of leaves. It's the big one on the left.

    I put it in this plastic tent and sprayed the leaves occasionally incase the central heating was drying it out too much, but it almost seems like the leaves started dropping when I added this!


    Tonight I just noticed one or two leaves with much larger beige coloured insects as seen in the photo aswell.

    I plan on tackling the mites with an insecticide or predator, but I do also wonder if my last lemon tree died due to poor humidity, light and temperature. It is in a north facing extension with big French doors, which does have radiators in it, but is the coldest room in the house.

    I measured the relative humidity over a few days and it ranged from 77 to 95%. The temperature ranged from 14 - 20C.

    If this raises any questions, then the plant can be moved to the front upstairs, the warmest and sunniest room in the house.


    The other two I bought from You garden about a month ago. The seem relatively happy but I don't like the look of the leaves. Look slightly twisted and curled to me:

    Any thoughts welcomed

    Could you say where you live and what sort of garden set-up you have please ? (Under some circumstances these sort of semi-hardy trees may do better outside)

    I gave up with lemon trees indoors after several failed attempts.
    One I clearly overwatered ( have you checked your for healthy roots???)
    Also, although they like some humidity, they also like airflow so the blowaway is good in one aspect and not in another.
    However, it is good at providing perfect conditions for pests ....

    Sorry...I'm no help, but just thought I'd offer my confused ideas....

    You could spray some neem oil on it as there’s no predators about. Have you got the winter plant food,lemons are fussy with feed.

    Edit - you could add a cup of water under the radiator to stop the air drying so much?

    I'm having a similar problem to you with an orange tree. I'm afraid I have no real advice to offer because everything I have tried has failed. I, like Nicos, am going to admit defeat and not buy any more

    I had one of those little oranges....went outside in the day in the GH and brought indoors during the winter.

    My advice would be to take it out of the tent. You want the tree to go through it's season...so dropping some leaves and going semi bare/bare doesn't mean it's dead.
    Put it in a spot where it gets the most sunlight as possible and ideally a cool room, not one that has heating going on and off and out of draughts. Constant temps going hot and cold won't help.
    Aphids often come when plants are brought indoors and are in a warm spot or have new fleshy green growth. Reduce your watering, water from the bottom and not the top. Keep the top earth from getting wet. Clean up any fallen leaves promptly.
    You can buy citrus feed for them. I think it may be too late now but there's different feeds for different seasons so maybe worth having a look.

    Mine died after a few years in the Summer after forgetting to water!

    I’ve got a lime tree, keep it in my unheated porch when it starts to get chilly at night, porch has external doors both to the front and to the house so doesn’t get too cold but not warm either, my anticipation was that it would need colder weather than the central heated house but protected from winter.

    Seemed happy enough last year and again this year so far, fruit continues to swell and doesn’t lose too many leaves.

    I’d say it is probably too warm.
