1. Problem With Indoor Lemon Tree

Asked by Anonymous - January 2, 2011

My lemon tree was given to us about 10 years ago. It was covered with brown scale. I treated it for that and it does produce lemons. The ones now are very large. I believe they are growing on a new shoot that has come up from the roots. This shoot has thorns. The rest of the tree does not. Before this shoot came up, the other part of the tree produced fruit.

Most of the time the leaves look very unhealthy. They are dull and mottled with yellow. I know it needs repotting, and I will do that this spring when I can get it outside. What kind of fertilizer should I be using? It is about 5 feet tall and in maybe a 3-4 gallon pot next to a large window on the south in our garden room. I do prune small dead branches and occasionally live ones for shaping for indoor growing.


2. Variegated Lemon Tree

I get wonderful fragrant blooms, but the fruit doesn’t set. Can the tree be self-pollinated by hand?


3. I Have Recently Acquired a Small Indoor Lemon Tree Which Is Now Flowering

Asked by lenparker - January 27, 2011

which is now producing a number of flowers, Do these flowers require fertilisation ?

  • If you would like fruit, then yes they will need to be pollinated. If the lemon tree is small, you may want to hold off until the lemon tree is larger. But if it is large enough that you feel it can support fruit, you can pollinate the flowers by using a small paintbrush to swirl inside the flowers and this will pollinate them.

4. Eureka Lemon Tree

Asked by julie fullerton - January 28, 2011

I have been given a Eureka Lemon Tree as gift. It is currently 2 metres tall and in a pot. Flowers are blooming, it is tall and slim. Can I plant next to a wall?
Will the tree bush out? Or should I put it in a very large pot free of the wall?


5. Lemonitis?

Asked by digga - January 31, 2011

My lemon (unknown type) has started to sprout the seeds while still in the fruit and on the tree. It’s about 12 years old and was neglected by our tenants for nine of those years. Is this a cultivation, feeding, or a position problem?

  • This is referred to as vivipary or a viviparous mutant. It happens because Abscisic acid (which keeps the seeds from germinating) in the fruit either break down or are not produced in high enough quantities.

    Lack of Abscisic acid can have a few causes. One would be unusual exposure to cold. Another is that the fruit produced or the plant itself has a mutation. It can also be caused by nutrient deficiencies, which would happen after neglect like you describe.

    Since the tree has not done this before during its fruiting life, this is likely that this is a one time issue. Resume proper care and it will correct itself.

6. Watering Flowering Citrus vs. Fruit Bearing Citrus

Asked by Anonymous - February 9, 2011

I have a dwarf lemon tree in a container (18 years old), and a Bearss lime in a container. My luck with the lemon tree had been spotty until I read a few years ago somewhere that flowering lemon/lime trees need a lot of water; and when it gets to fruit bearing stage, it needs less (twice a week vs. once a week/approx). I didn’t write it down and now I’m worried it may be vice-versa! I don’t want to mess it up, and I’m starting to wonder if I have it backwards. My lime tree started with 14 baby limes and now just has 8. My lemon tree has a ton of blooms on it and I don’t want to loose whatever babies I get.

  • When growing fruit, citrus trees do need quite a bit of water. I would not cut back water for them when they are fruiting, especially when they are in containers. In the ground, they can access water from deeper depths, but in containers, you are their only water supply and it is just best to keep them well supplied for best growth. I would suggest regular water while flowering and more water while fruiting, especially early on when fruiting.
