Why avocado trees are painted white, have you ever thought of ways of pests control on your farm or new farming venture idea?

The story behind why avocado trees are painted white: A Farmer’s Perspective

As a farmer, I’ve spent countless hours tending to my avocado orchards. Over the years, I’ve noticed curious onlookers asking the same question: Why are the avocado trees painted white? At first glance, it might seem like an unusual practice, but there’s a very good reason behind it, one that I’ve come to understand intimately through my experiences in the field.

Let me take you back to one of those blistering hot days when I first learned about the importance of this technique. It wasn’t long after I had planted a batch of young avocado trees that I started noticing something troubling. The branches of some of the seedlings began to show signs of damage. Leaves were curling, and the bark was becoming cracked and sunburned. I had heard about sunscald, but it didn’t fully hit me until I saw it for myself. Sunscald happens when the intense heat of the sun causes a tree’s bark to dry out and crack. It can lead to serious damage, sometimes even killing the tree.

Challanges in avocado farming

I wasn’t the only one facing this challenge. Many farmers, particularly those dealing with younger trees or those that have suffered from conditions like phytophthora root rot, experience similar issues. Phytophthora root rot weakens the trees, making them more vulnerable to stressors like sunscald. That’s when I learned about the solution: painting the trees white.

The white paint acts like a protective shield, reflecting sunlight and reducing the intensity of the heat hitting the tree’s delicate bark. It helps prevent sunburn, ensuring the tree can grow strong and healthy. You’ll typically see this practice on young seedlings or trees that have lost their leaves due to disease or other environmental factors. These trees are particularly susceptible to sunscald because their bark becomes exposed, and the paint offers a layer of defense.

Proper timing

Another time I found myself using the white paint was after a round of pruning. The cutting of branches often exposes parts of the tree that were once protected by leaves. These new, exposed areas are at risk of damage from the harsh sunlight, so I would mix the paint and apply it to the freshly cut branches to shield them from the sun’s scorching rays.

Occasionally, the paint isn’t just plain white. When the trees show signs of lesions on the bark, I mix a fungicide with the paint. This dual-purpose mixture not only provides the sun protection but also helps combat fungal infections that might take hold in the damaged areas. Over time, I’ve found that this combination works wonders in keeping my trees healthy and productive.

Looking back, I can see how this simple practice of painting avocado trees white has made a world of difference in the health of my orchard. It may seem like a strange thing to do at first, but for farmers like me, it’s a necessary and effective measure. It protects our trees, helping them thrive in even the harshest conditions, and ultimately, ensures a better harvest in the years to come.
