Lemon Trees and Ants

I recently potted a new young Eureka lemon tree. Over the last two weeks, there are concentrations of ants on the underside of the leaves together with what looks like a white fungus. I have tried spraying with a rooibos tea mixture, but with no effect. How do I get rid of this?

Your lemon tree likely has been affected by aphids, which secrete honeydew. This sweet substance is what normally attracts the ants and is what they feed on, so in order to rid the plant of ants, you'll first need to get rid of the aphids. Neem oil can help with this.

Lemon Tree

My Eureka lemon tree, which has always produced large and plentiful fruits, has suddenly started to produce smaller fruit covered with light brown scale. Also, there are not many of them and not much blossoming. Please can you help?

It sounds like you may have an issue with mites or scale bugs. The use of neem oil is very effective for treating these pests and is perfectly safe for plants, people, and even beneficial insects. Here is an article with more information: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm Once the tree is no longer stressed from the pests, it should begin to perk back up and produce again. You may also want to give it some fertilizer. This article will help: https://www.gardeningknowhow.com/edible/fruits/lemons/learn-about-fertilizer-for-a-lemon-tree.htm

Lemon Tree

I just purchased a lemon tree from a garden center. The person there was not much help in answering my questions. The grower is a company called Monrovia and the species is the Eureka lemon. With no other lemon trees in the area, will this tree bear fruit?

You do not need another lemon tree to produce fruit. On average, these trees begin bearing fruit around four years of age.

My 2 year old, 3m high, Eureka lemon tree does not bloom or bear fruit. We have tried all kind of fertilizers, etc. Will pruning the tree help at all?

I would try giving it some phosphorus rich fertilizer, like bone meal. If it is lacking phosphorus, it will not be able to produce blossoms (which means no fruit.). Here is more info that should help: https://www.gardeningknowhow.com/edible/fruits/lemons/lemon-tree-not-fruiting.htm

Dwarf Eureka Lemon Tree Not Blossoming

I planted a dwarf Eureka lemon tree about a year and a half ago in my backyard. It had a couple of blossoms and the beginnings of a tiny lemon, but everything fell off. My nursery person said I was overwatering it, and it should be deeply watered only once every two weeks in our area. I’ve started doing that, but now it has no blossoms. I know this kind of tree grows here because I bought it at our local nursery and many people in my neighborhood have successfully grown it. It is in full sun. I also used a fertilizer recommended by the nursery. Any suggestions?

The requirements for lemons are very similar to that of limes.

Eureka Lemon Tree With Yellow Leaves

So I brought home a Eureka lemon tree that had *slight* yellowing of the leaves. I planted it and it refuses to grow. Leaves have turned all yellow and are starting to fall off. I’ve done everything I can think of. What now? Things I’ve tried:

Dr Earth Fruit tree fertilizer
Epsom Salt
Spraying the leaves with kelp mixture
Mulching

The leaf spray seemed to help the most, although not 100%. Some parts of the previously yellow leaves are now more green, but not totally healed. I’m currently trying water restricting, in case it is a case of over watering, but the tree (which has small lemons on it and did when I bought it), has not put on any new leaves and hasn’t grown at all. It hasn’t died (yet–and I really don’t want it to!) but it is that sickly pale green/yellow color overall. Please help!!!

Your tree is most likely shocked from the move from pot to ground.
Yellowing leaves are generally a watering issue, either to much or to little.

A newly planted tree will need daily water for the first 2 weeks and with temperatures above 85 degrees you will most likely need 2 waterings a day.
Make sure the tree was properly planted and that the soil is adequate for the tree success.

Add 2 to 3 inches of hardwood mulch around the base of the tree to help it retain moisture.
