Why is My Loquat Tree Dying in Summer Heat, and How Can I Save It?

Loquat trees are native to tropical regions and prefer warm temperatures between 15-24°C. They can tolerate temperatures as high as 30°C, but anything above that can harm their health. When exposed to temperatures above 33°C, the Loquat tree leaves can wilt and eventually die.

Use a shade cloth or sheer curtain to filter the sunlight and reduce the temperature around the tree.
If you notice that your Loquat tree is struggling, you can move it to a cooler location. Choose a spot that is shaded or has a cooler temperature, such as a basement or an air-conditioned room.
Loquat trees must be watered deeply and regularly, especially during hot weather. Check the soil moisture regularly and water it as needed.

Identifying Nutrient Deficiencies in Loquat Trees and Remedies to Revive Them

Signs will include lots of shedding leaves along with discoloration on the leaves. This will vary depending on the different types of deficiency. To simplify the symptoms of these, take a look at them below.

Deficiency and their symptoms

Nitrogen- Entire leaves turn yellow
Phosphorus- Purple or brown spots
Potassium- Leaf edges turn brown
Calcium- Newer leaves grow paler than older leaves
Manganese- Yellow regions between the veins of leaves
Zinc- Bronze-colored splotches in younger leaves

To fight the deficiency, you will need compost or fertilizer. Compost is a very good and versatile option because it’s made from organic waste. So naturally, it has a diverse spectrum of nutrients. It’s suitable if your Loquat tree has multiple deficiencies and can address them all.
