I've recently acquired a Lemon Plant which was quite well established (one little Lemon and several flowers) but it doesn't seem to be very happy at my house.
I have it in a very sunny South facing window in a warm room which I use for germinating all my seeds. I haven't watered it very much as per the instructions. The flowers still look quite healthy but more than half the leaves have curled up and are ready to fall off (several have already).
Any ideas?
The huminity in your livingroom is to low,to dry air.Put the pot where the lemontree is growing in into a bigger pot with on the bottum those clyballs and soak them than you make a nice micro-envirment around the plant .

There are two possibilities for overwintering:
In a cool room in the house with the following basic rules:
The warmer the room is, the brighter it should be; the plant should be stood right beside the window in a permanently heated room. Lack of light will result in yellowing or falling of individual leaves. Vigorous pruning in the spring before the plant begins to shoot will help it produce new healthy growth.
In a cool (5-10c) if necessary dark room. Reduce watering drastically, but avoid complete drying out of the rootstock. Here, increase falling of leaves due to lack of light is normal. Prune back in the spring, remove it from it winter quarters. Let it get used to sunlight again gradually and water regularly but sparingly. Fertilise weekly. Frequently cut into shape.
Correct Watering - Generally one can say:
During the growth phase, water regularly and plentifully.
Avoid water logging. Pour off excess water that builds up in dishes or secondary pots.
Use water that has been allowed to stand for a while and is free of lime.
Citrus plants have a high requirement on water on hot days, and yet are sensitive to waterlogging. This means watering them sparingly but frequently so that the rootstock can never dry out, but is also never too moist. It is better to water too little than too much. Even if some leaf damage occurs due to rootstock being too dry for a long period (curling of leaves, dried up leaf tips) this is not dramatic compared to the risk of almost irreparable root rot caused by root rot.
I have recently acquired two lemons and one orange tree.  One of the lemons was yellowing. I think it was due to watering them with tap water, which seems to have halted after reading this book.Â

Thanks for for help - I think I will put it in a lighter place and hold back on the watering a bit more.
Hi Simhop
Lemon plants don't like change: a sudden change in average temperature, or amount of light, can cause them to drop their leaves - its quite common for this to happen - but with the correct care and some TLC they should adjust OK to their new suroundings.
When you water, let the water flow through & tip excess out of dish, and always let it almost dry out completely before the next watering. They hate waterlogging and love light.
Check for spider mites too: I don't know where they come from, but they always seem to seek out my Citruses.
my mums plant is in the conservatory.it has not had lemons now for a year or so..it has about 8 yellow leaves now lol.
so it needs its own micro climate, and watering heavily, then let it dry out, then soak it again.
is this correct?
many thanks
