What is a Nematode?

Val Bradley

For any gardener wishing to reduce the number of manufactured chemicals they use in the garden, even if they are organic ones, nematodes may be the answer.

These minute beneficial eelworms, bred to attack specific problems like vine weevils, leatherjackets, slugs or codling moth, are completely compatible with organic gardening and pose no threat to pets, children or wildlife.

As living creatures, they need special care if they are to survive. For this reason, they are usually bought by mail order and will arrive in a dry state so they can be transported safely. The pack will need to be refrigerated to maintain this state until you are ready to use them.

Netmatodes in container

Always check the pack for the required temperature when you are ready to apply them, because if it isn’t right, they may not survive. As long as the weather is suitable, make up a stock solution of the nematodes in a bucket and then apply it to your plants or lawn immediately.

The nematodes need moisture in order to move through the soil or compost, so never apply during a dry spell or, if you have to, make sure you irrigate the area or pots before and after use. Ideally, apply when it’s raining to make sure the area is damp enough. Keep the area moist for at least two weeks after application for the best results.

Netmatodes mixed with water

Nematodes are an ideal way to treat vine weevils in containers, as you can apply the solution directly where it is needed.

Once there are no more pests to control, the little eelworms will die off - so if you realise the pest is back with a new generation, you need to apply more nematodes. It may take several treatments to control pests in a large garden.
