How to take care of citrus trees in winter where weather gets colder than 30 degree F? I live in Pennsylvania southeastern region. I have one lemon tree that is about 4 months old. Currently, I have it in my house as outside temps are low. My house, however, does not have areas that get much sunlight. I wanted to know what I need to do to keep it from dying.
You potted Lemon Tree needs bright light, consistent watering, hight humidity and fertilizer.
You may need to add a grow light to the space for your Lemon Tree to successfully winter over indoors if you do not have a good South exposure light.
Here are some links for you.

We received a limequat in March. It was transported bareroot and we potted it immediately in a large enough pot to provide some space for the roots. Initially, it did well, had lots of flowers, which turned into beautiful roots. Then it started curling its leaves, which eventually dried out. It never dropped the leaves or fruit. The outer branches are dried out, the soil feels moist. I couldn't tell if it started curling leaves due to over- or under- watering. Any thoughts/help/suggestions?
Watering should take place when the well draining soil is dry.

I have this tree in my backyard. I can't figure out if it's an orange or some kind of sweet lime (I've see a kind in India that's a lime but quite sweet). It's too sour for an orange and too sweet for a lime. The fruits take a long time to get to yellow. I don't know if that's how it's meant to be, sweet/sour, or it's just an orange tree that's somehow not producing sweet fruit and needs to be fixed. I see some leaves curling and dead branches, so there could be aphids or scale bugs that I might need to take care of. What does this tree need? Any help would be appreciated. TIA Norm.
It is normal for citrus fruits to take a long time to mature. For oranges, anywhere from 8 to 15 months is possible depending on the variety. One possibility is that your fruits aren't mature yet, and that they will continue sweetening, so it's best to leave most of the fruits on the tree and taste one every few weeks to see if they're ripe yet.

There are also several naturally sour orange varieties, used for grafting rootstocks, ornamental trees, or to produce fruit for making marmalade. Here is more information:

I live in Hawaii.I've read a lot about my question, and in my experience, my fruit seems to be ripe when there is a certain give (not soft) when squeezed. Granted, color seems to be quite indicative of ripeness but doesn't always seem dependable for me. I've had a green tangelo be wonderfully ripe and sweet, and it had that...'give.' I haven't read anything like 'my citrus testing,' thus I am very curious as to what you will say.
You are probably correct. Knowing when citrus is ripe depends on several factors and seems to take experience. Of course, knowing when your variety of citrus usually ripens in your area and how long the fruit has been on the tree will help, but a combination of color, timing, and the "give" you describe would probably allow you to harvest at the peak of flavor.
What causes our leaf to curl up? Some have brown on the underside of the leaf. Is this a mold?
Here is a link that will help you pinpoint the cause.

During winter, I brought my citrus plant into my lounge. Unfortunately, I did not give it a chance to adapt to the new temperature slowly. The temperature inside is around 19-21 degrees. My plant lost all its leaves except for 1 little branch within 2 weeks. Now the branches are drying out. What can I do to save my plant so that it gets leaves and flowers? It is winter right now. I have put in a light that gives it a few hours of light during the day, and I even put in a humidifier to hopefully give some humidity since it is very dry inside.
The loss of leaves is probably due to the lower light levels combined with the lower humidity (depending where you live). The humidifier should help. Also, check the tree for any pests on the leaves, since these can cause leaf drop. The tree should still recover in the spring and put out new leaves. Just make sure you water the plant enough to keep the soil a little bit moist but not too wet.
When you move the plant back outdoors in spring, do it gradually so it has time to adjust to the higher levels of sunlight and the temperature change. Placing it in the shade first, then moving it to sun is a good idea.
I have a property on Pico in the Azores and there are a number of lemon and orange trees that are very old. Is there any advice you could offer in addition to the RHS link and when posted publicly on this site I got the same answer. I have asked the RHS and gardeninknowhow website and have been provided with the following link, which is useful: http://extension.psu.edu/plants/gardening/fphg/pome/pruning/pruning-a-special-case-renovating-old-fruit-trees I am guessing the trees are at least 50 years old if not older, attached are pictures of the trees, I was wondering if I should open the trees up. Your thoughts and help would be appreciated Thanks Dave
