Lemon Tree Problems

[golden14]

Hi,
I have had my Lemon tree for over a year now and keep it in my conservatory, last year it was fine even despite below freezing temperatures (Which is unusual here on the Isle of Wight), however this year in the past week it has suffered Major leaf wilting, I have cut back on the watering as it stated on the care instructions it came with. Any ideas on what might be causing it and what I could feed it with to perk it up?
It's my first ever try at fruit growing so please be gentle with your answers!
Thanks
Dickie

What is the temperature in your conservatory?

Have you used any fertilizers recently?

Somehow it sounds like fungi to me. Do you have any spots on the leaves?

A lemon tree that has lost many leaves and has dead wood might well be sick. Prune any dead wood off to encourage new growth. Problems can also be caused by a severe lack of water. Citrus trees need lots of water. In Adelaide apply about 3 to 4 centimetres of the equivalent of rain each week from spring until autumn. The way to see whether you're doing this correctly is simply to use a cup, turn on a sprinkler and see how long it takes to get 3 to 4 centimetres of water in the cup. Elsewhere around Australia use commonsense. Feel the leaves. If they feel cool and thick, the tree is fine, but in hot weather, if they feel dry and leathery, the citrus probably needs a drink. Scales are small insects. They are most commonly found on the new wood of the tree, but can also be found attached to fruit and foliage. These insects show up as waxy bumps on the lemon trees. They cause the leaves to drop and turn color by sucking sap from the tree, and leave behind a sticky substance that attracts ants. Control and eliminate scales by spraying an insecticide recommended by your local citrus expert.

Thanks for the replies folks and sorry for not posting back sooner. yes I think watering is part of the issue (Said on the instructions to water minimally in Winter so I did just that) - been giving it regular water again, close to the levels I gave it in Summer even, and it has picked back up. No dead wood to really trim away.
With regards to the fungal type thingy(!) some of the leaves and fruit have little brown spots on the and are sticky to the touch (like dried citrus), but it doesn't affect the whole plant and whilst some of the lemons have the above mentioned on them they still seem to be growing fine.

With regards to conservatory temp, I work in it during the day so it probably is around 14-16 degrees in the day but will be dropping down to just above freezing at night in the past few days (Due to extreme weather in the South East of England we even have had 5-6 inches of snow here on the Isle Of Wight.
Normally weather isn't an issue here as I grow and sell tomato plants but I did get criticised by someone on here light heartedly for putting them outside at the end of March, hadn't the heart to tell them they'd actually been hardened up in Feb...
Thanks again to everyone who replied

i hope you can find a solution for your worries, just make sure not to water too much and they get sunlight they need.

Water your lemon tree WELL before you apply the fertilizer. Water it WELL after you apply the fertilizer.Apply according to package instructions, about every 3 - 4 MONTHS.Also, water your lemon trees deeply once a week. Let the shallow water retention basin fill up several times.
