Citrus greening, also known as HLB (Huanglongbing), has become one of the biggest threats to citrus trees, especially in Florida. What many homeowners don’t realize is that backyard trees are just as vulnerable as commercial groves.

If you’ve planted a citrus tree, protecting it early is one of the most important steps you can take.

What Is Citrus Greening (HLB)?

HLB is a bacterial disease spread by a tiny insect called the Asian citrus psyllid. Once a tree is infected, there is no cure. Over time, the tree declines, produces poor fruit, and eventually dies.

Why Backyard Trees Are at Risk

Even if you only have one tree, it can still be exposed. Psyllids travel easily between properties, meaning your tree is at risk even if your neighbors don’t grow citrus.

Young trees are especially vulnerable during their early growth stages.

How to Protect Citrus Trees from HLB

1. Block the Insect, Not Just the Disease

The only way HLB spreads is through psyllids. If you stop the insect, you stop the disease.

This is why physical protection is one of the most effective methods available.

2. Use a Protective Tree Cover

A breathable mesh cover creates a barrier that prevents psyllids from reaching your tree while still allowing sunlight, air, and water through.

This method is widely used in commercial groves and is now available for backyard growers through solutions like Tree Defender.

3. Protect Trees Early

The first 1–2 years of growth are critical. During this time, trees are more vulnerable and need consistent protection.

4. Reduce Reliance on Sprays

While sprays can help, they require constant application and may not fully prevent exposure. A physical barrier provides continuous protection without repeated treatments.

A Simpler Way to Protect Your Tree

Tree Defender was developed by Florida citrus growers to provide a simple, effective way to block psyllids at the source.

With over a decade of real-world use and more than 1 million covers installed, it brings commercial-level protection into your backyard.

FAQs

What is the best way to prevent citrus greening?
Preventing psyllids from reaching your tree is the most effective method. Physical barriers like mesh covers provide consistent protection.

Can citrus greening be cured?
No. Once a tree is infected, it cannot be cured. Prevention is key.

Do backyard citrus trees really need protection?
Yes. Even a single tree can be exposed to psyllids and become infected.
