How to revive a dying avocado tree?

To revive a dying avocado tree, first, make a list of all the symptoms you’re experiencing. Take it to a horticulture store and have an expert there identify the plant for you.

Doing so will help you devise a strategy for rejuvenating the tree and, perhaps, curing whatever ailment is plaguing it.

Root – knot and fungal diseases are a problem for many avocado plants. A dying tree can be brought back to health if the right measures are taken. A healthy tree means good fruit for years to come. 

Here are a few steps you can take yourself if you don’t feel like visiting an expert:

Gypsum can be used.

Because of the high calcium content of gypsum, it can prevent the growth of several types of root rot.

Crush up approximately 25 pounds of gypsum and mix it into the top six – ten inches of soil.

As a result of the abundance of calcium present, the spore-forming process for some fungal infections is disrupted.

Make Mulch Part of Your Garden Routine

Spreading a few inches of hardwood mulch at the tree’s base can help hide its exposed roots and stimulate healthier development.

Some fungal illnesses can be prevented or even eradicated by the bacteria that will flourish and spread thanks to the wood mulch.

Don’t water as frequently.

Overwatering can be a problem for some trees. To overwater a plant is to encourage the growth of fungi, as is the case with all plants.

To prevent fungal development, reduce watering frequency. Dryer conditions are hostile to the spores.

Test the water

Some elements, like boron, can promote the growth of bacteria and fungi that are harmful to humans.

The water in your yard can be checked if you’ve already done all of that and the avocado tree is still sick.

Check the Drainage 

Root rot and other issues are brought on quicker by waterlogging because of poor drainage in the soil.

Digging drainage systems all around tree roots is one method of avoiding this problem.

However, it may be simpler to just dig little tunnels with a spade all around the roots then leave them covered with loose dirt, rather than using channels of PVC pipe as some people do. Overflow water will have a decent path to drain away.

You may maximize the efficiency of the drainage canals for your avocado tree by planting it on sloping ground.

Substitute Old Soil 

The upper layer of soil can be removed and replaced with new soil in addition to other procedures.

Pathogens close to the roots are less likely to survive once this treatment is applied.

Fertilize Properly

Avocado trees require a certain balance of soil nutrients in which they are planted.

Sometimes there is an insufficient amount of nitrogen or other nutrients. The tree’s defenses may weaken as a result, making it more susceptible to diseases like root rot.

Get some high-quality fertilizer and solve the problem.

Start using it regularly in the winter and continue doing so for the next four seasons. Having access to high-quality soil and nutrients will help the tree resist illness.

Put Fungicides to Good Use

Last but not least, you may always purchase a high-quality fungicide to use in combination with other treatments if nothing else seems to work. This will aid in the destruction of the disease-causing bacteria.

Why do avocado trees die?

The avocado tree can be lost if the feeder roots are attacked by the fungus Phytophthora cinnamomi, the cause of avocados phytophthora root rot. 

Despite over 60 years of research, no effective cures or prevention strategies have been discovered, and the number of lives lost is rising.


  • Small, pale green leaves that typically wilt and end in brown tips and drop easily are the first symptoms of the illness to be seen in the tree canopy.
  • Avocado trees lose their leaves and branches from the tips inward until only the trunk remains.
  • Depending on the soil type, cultural norms, and weather, the mortality of an avocado tree might take anywhere from some months to many years.
  • Diseased avocado trees in their last stages of collapse may not have any of their little feeder roots left. In contrast to the creamy white color of healthy feeder roots, diseased taproots are often black in color, brittle, and decaying.

How to take care of your avocado tree?

The environment in which your avocado tree is being grown will have a significant impact on its overall health.

Maintaining good hygiene and sanitation year-round will help prevent diseases and other issues.

Please take care to water the tree as instructed. Avoid watering it during the middle of the day, when the temperature is already high enough to evaporate the water and leave the soil dry.

Too much water can lead to fungal development and root damage, therefore it’s important not to let the soil become too wet either.

As was previously discussed, you should also guarantee there is adequate drainage.
