Citrus Slow Decline: A Guide for Home Gardeners


Citrus slow decline is a serious problem that can affect citrus trees, including oranges, grapefruits, and lemons. It is caused by a tiny worm called a nematode that attacks the tree’s roots. If left untreated, citrus slow decline can eventually kill the tree.

Symptoms of Citrus Slow Decline

The symptoms of citrus slow decline can be subtle at first, but they will become more noticeable as the disease progresses. Some of the most common symptoms include:

  • Yellowing leaves
  • Stunted growth
  • Small, misshapen fruit
  • Thinning canopy
  • Bare branches

Causes of Citrus Slow Decline

Citrus slow decline is caused by a nematode called the citrus nematode. Nematodes are microscopic roundworms that live in the soil and feed on plant roots. The citrus nematode attacks the roots of citrus trees, causing them to become damaged and unable to absorb water and nutrients.

Managing Citrus Slow Decline

There are a number of things you can do to manage citrus slow decline in your home orchard. Some of the most effective methods include:

  • Prevention: The best way to manage citrus slow decline is to prevent it from happening in the first place. This can be done by:
    • Planting nematode-resistant rootstocks
    • Buying only certified nematode-free plants
    • Practicing good sanitation, such as cleaning tools and equipment
    • Rotating crops with non-susceptible plants
  • Treatment: If your citrus tree has already been infected with citrus slow decline, there are a number of treatment options available. Some of the most common treatments include:
    • Chemical nematicides
    • Biological control agents
    • Cultural practices, such as improving soil drainage and reducing stress on the tree

Additional Tips for Growing Healthy Citrus Trees

In addition to managing citrus slow decline, there are a number of other things you can do to keep your citrus trees healthy and productive. Some of these tips include:

  • Water your trees deeply and regularly. Citrus trees need about 1 inch of water per week, but more during hot, dry weather.
  • Fertilize your trees regularly. Citrus trees need a balanced fertilizer that contains nitrogen, phosphorus, and potassium.
  • Prune your trees regularly. Pruning helps to remove dead or diseased branches and encourages new growth.
  • Protect your trees from pests and diseases. Citrus trees are susceptible to a number of pests and diseases, including aphids, scale, and citrus canker.

By following these tips, you can help your citrus trees stay healthy and productive for many years to come.
