I grow lemon for several years, but this year the new, already expanded leaves begin to dry up from the top or sides and fall down! Any ideas why?
It is possible that this is insect damage, likely mites. They can be very small and hard to spot. You can check for them by holding a white piece of paper under some of the affected leaves and gently shaking the branch. If there are mites, you will see specks on the paper. They can be treated with a miticide, like neem oil.
Another less likely possibility is that it is a fungus and a fungicide should clear it up. If you use neem oil, it is both a fungicide and a miticide and will treat both possible issues with one solution.
Hi. I have a lemon tree, which I won in a Garden Invaders competition 10 years ago. Don't know the variety of it. We lived in Manchester, where it was outside in a pot 24/7. Moved up to Cumbria, where it is colder; therefore, we have to bring it inside for several months of the year. It currently has 4 full lemons on it and over 70 potential buds. My question is, can I put it under a U/V light in a small heated room during the colder months, and if so, what distance would the bulb have to be from it? I am thinking of a ceiling light on a pendant, so the bulb would be about 5-6 foot above it.
If you will be putting it in a room with no windows, the UV light will need to be within inches of it and even that may not be enough. They need alot of light. They can do well as a houseplant if given a bright window to sit in or next to. If this is not possible, several UV or florescent lights placed very close to the tree should be enough to get it through the winter.
We have had our lemon tree two years. Last year, our small tree (approx. 2' tall) had an abundance of lemons that ripened in Sept-Oct and were delicious. This year, all was on schedule, but this week we began to notice brown spots that look like rot appearing on several lemons on the tree just as the fruit begins to turn from green to yellow. The skin is in the process of turning yellow, and I would anticipate another two weeks to completely ripen. What causes the brown to appear and what am I doing wrong?
There are a couple of disease that can cause this kind of problem. This article has a list and pictures of the different diseases to help you pinpoint which one it is and help for fixing the issue:

Will a lemon tree seedling that has appeared in the garden (it's 3 inches high now) have fruit or does it need to be grafted?
It likely will fruit, but it may take 4-6 years before it is mature enough to fruit.
I have a Eureka lemon tree that I recently bought potted in my yard. When I bought it a few weeks ago, I chose one with lots of flowers and buds. It is around 140 cm tall. There are LOTS of buds and flowers in different stages all over it and I have just noticed this morning that there are around 10 flowers where the petals have fallen and there are what appears to be tiny green lemons! The biggest one is around 1 cm (I am very excited having never grown anything before!). Anyway, I was wondering if these will really grow into proper lemons and how long they will take to grow?
Is there anything special I need to do now? The pot is fairly big, about 50 cm, and in a very sunny spot and I am watering it every other day. When will I get to pick a lemon to use?
Yes, you can actually get lemons from the tree, even if you are growing indoors part of the year.
The trick to to make sure that the tree is getting enough water. The soil can never go dry. The fruit will be the first thing aborted by the plant if it feels it is not getting enough water. You may also want to give the tree a slow release fertilizer. This will ensure the tree has all the nutrients it needs as the fruit develops.
I have one lemon on my young tree that has been growing 5-6 months. It is at least 3 1/4" L and 2 1/2" in diameter. It is still bright green. What is their usual time to maturity?
Lemons are ripe and ready to pick once they have completely turned yellow. However, slightly green-yellow ones can still be picked and will normally ripen off the tree, provided they are large enough. They should also be somewhat heavy feeling and hard with a ‘glossy’ look to them. If it’s kind of squishy, you’ve waited too long. The lemon should also be about 2-3 inches in diameter.
The amount of time time it takes for a lemon to ripen can vary depending on several things. First, different varieties have different ripening times (typically between 3-18 months). Second, the conditions the lemon is grown under can shorten or lengthen the time it takes for it to get ripe. For instance, if it is not warm enough, the ripening process will slow down.
I would like to know what I should feed lemon trees with or what fertilizer they need to obtain the best fruit bearing results.
