Why Are My Citrus Tree Leaves Burning?
Burned citrus leaves are one of the most common problems homeowners notice, especially during hot summer weather. Leaves may develop brown edges, scorched areas, crispy tips, or large dead sections that make the tree appear unhealthy.
Many people assume disease is causing the damage, but in many cases the problem is related to environmental stress. Excessive heat, improper watering, root damage, fertilizer burn, or salt accumulation in the soil can all cause citrus leaves to appear burned.
Arizona's extreme summer temperatures place significant stress on citrus trees. When temperatures become excessive, the tree can lose moisture faster than its roots can replace it. The result is often brown, dry leaf edges and scorched foliage.
Overwatering may also cause root damage that prevents the tree from properly absorbing moisture. Ironically, a tree receiving too much water may develop symptoms that look similar to drought stress.
Salt buildup from irrigation water or excessive fertilizer applications can also damage citrus roots and cause leaf burn. If left untreated, tree health may continue to decline over time.
The best way to identify the true cause is to evaluate watering practices, soil conditions, root health, and any additional symptoms present on the tree.

How To Protect Citrus Trees
Proper watering, mulching, soil management, and early diagnosis are often the best ways to reduce leaf burn problems. Understanding the underlying cause can help prevent unnecessary treatments and improve long-term tree health.
If the problem continues to worsen, a professional evaluation may help identify root problems, diseases, or environmental conditions affecting the tree.
