What’s Killing Your Lemon Tree? Signs to Look Out For

Identifying a lemon tree in distress and implementing measures to restore it can be quite a task. Let's delve into the signs and solutions.

Recognising a Lemon Tree’s Distress

One of the surefire ways to tell if your lemon tree is dying is by observing the foliage. Leaves turning brown or yellow, curling up, and subsequently falling off in bunches is a signal of a serious problem. Another symptom is when the branches start to diminish, become arid and begin to crack, which is a clear indication of the tree's declining .

To further confirm your suspicion, one can conduct a simple test. Cut about an inch off a branch and look for the presence of green inside. If it appears dry instead, the plant is probably dead or on the brink of dying.

Steps to Revive a Dying Lemon Tree

Address Over-watering

If the issue is over-watering, the remedy is to allow the earth a few days to dry off. Damaged roots should be removed and a new watering schedule should be established, ensuring the tree isn't getting too much or too little water.

Combat Thermal Stress

Lemon trees thrive in a specific temperature range, from 21-30°C. If the tree is exposed to extreme temperatures, it can cause what is referred to as thermal stress. The solution to this is to either use protective coverings for the tree or move it indoors for protection. Applying mulch during colder weather can also be beneficial to the tree's overall health.

Manage Infestations

Sometimes a tree's health can be compromised by pests, such as aphids and scale insects. Immediately addressing the issue is key to the survival of the tree. The first step is to rinse the tree, followed by regular application of a suitable solution such as soapy water or neem oil until the infestation is under control.
