One of the common causes for lemon tree leaves turning yellow and falling off is a lack of iron in the soil. Iron is an essential nutrient for plants, and when there is a deficiency, it can lead to yellowing of the leaves, known as chlorosis. Iron deficiency in plants is more likely to occur in alkaline or poorly drained soils.
Another possible cause for yellowing and leaf drop in lemon trees is overwatering. When the soil is constantly saturated, it can lead to root rot and poor nutrient uptake, including iron. It is important to ensure that the lemon tree is not being overwatered and that the soil has proper drainage.
To address the iron deficiency, you can apply a citrus or nitrogen fertilizer that includes iron. This will help provide the necessary nutrients to the lemon tree and alleviate the yellowing of the leaves. Follow the instructions on the fertilizer packaging for proper application rates.
In addition to iron, nitrogen deficiency can also cause yellowing of the leaves in lemon trees. Nitrogen is a vital nutrient for plant growth and is responsible for leaf development. If you suspect a nitrogen deficiency, you can also apply a citrus or nitrogen-rich fertilizer to provide the necessary nutrients.
It is important to note that while iron or nitrogen deficiencies are common causes of yellowing and leaf drop in lemon trees, there could be other underlying issues. It is always a good idea to assess the overall health of the tree and consider factors such as sunlight exposure, temperature, pest infestations, and diseases. These factors can also contribute to leaf yellowing and drop.
In my personal experience as a gardener, I have encountered lemon trees with yellowing leaves due to iron deficiency. Applying a fertilizer with iron has been effective in correcting the issue and restoring the health of the tree. However, it is important to monitor the tree’s progress and make adjustments as needed. If the problem persists or worsens, it may be necessary to consult a professional or seek further advice from a local gardening expert.
