How to Get Rid of Nematodes on Viburnum Plant

Nematodes are microscopic worms that can cause damage to the roots and leaves of a viburnum plant. They feed on the plant’s nutrients, causing stunted growth and yellowing of the leaves. If left untreated, nematodes can eventually kill the plant. Here are some effective ways to get rid of nematodes on your viburnum plant.

Identify the Problem

The first step in getting rid of nematodes is identifying the problem. Look for symptoms such as stunted growth, yellowing leaves, and wilting. You can also dig up a small section of the root system and examine it for signs of nematode infestation. If you see small, white worms, then you have nematodes.

Use Nematode-Resistant Varieties

One way to prevent nematode infestation is to choose nematode-resistant varieties of viburnum plants. There are many different varieties available that are resistant to nematodes, including Viburnum carlesii ‘Compactum’ and Viburnum tinus ‘Robustum’. When selecting a new viburnum plant, be sure to ask the nursery if it is resistant to nematodes.

Remove Infected Plants

If you have a severely infected viburnum plant, it may be best to remove it altogether. This will prevent the nematodes from spreading to other nearby plants. Be sure to dispose of the infected plant properly, either by burning it or placing it in a sealed bag and throwing it away.

Solarize the Soil

Another effective way to get rid of nematodes is to solarize the soil. This involves covering the soil with clear plastic and allowing the sun’s heat to kill off any nematodes that are present. To do this, first remove any existing plants and debris from the area. Then, moisten the soil and cover it with clear plastic. Leave the plastic in place for 4 to 6 weeks during the hottest part of the summer. This will heat up the soil and kill off any nematodes that are present.

Use Nematicides

If nematode infestation is severe, you may need to use nematicides. These are chemicals that are designed to kill nematodes. There are many different types of nematicides available, including organic and synthetic options. Before using any nematicide, be sure to read and follow the label instructions carefully.
