What is Eating My Tomato Plants in the UK?

If you are an avid gardener in the UK, chances are that you have encountered the frustrating problem of something eating your tomato plants. Tomatoes are a popular crop for gardeners, and they can be susceptible to a range of pests and diseases. However, with the right knowledge, you can identify the culprit and take steps to protect your plants. In this article, we will explore the common pests that target tomato plants in the UK and how to prevent them.

Slug and Snail Infestations

Slugs and snails are some of the most common pests that plague tomato plants in the UK. These slimy creatures are voracious eaters and can decimate your plants overnight. You can tell if your tomatoes have been attacked by slugs and snails if you notice irregular holes in the leaves and fruit. They tend to munch on the softer parts of the plant, leaving behind ragged edges.

To prevent slug and snail infestations, try some of these techniques:

Handpick and remove the slugs and snails.

Set up copper barriers around your plants. Slugs and snails are deterred by the electric shock that copper gives off.

Use slug pellets or beer traps to attract and kill them.

Aphids

Aphids are small, pear-shaped insects that cluster on the leaves and stems of tomato plants. They suck the sap out of the plants, causing the leaves to wilt and yellow. You may also notice a sticky residue on the leaves and fruit, which is a sign of honeydew, a sugary substance the aphids excrete.

To prevent aphid infestations, try some of these techniques:

Encourage natural predators, such as ladybirds and lacewings, that feed on aphids.

Use insecticidal soap or neem oil to smother and kill the aphids.

Attract beneficial insects by planting companion plants, such as marigolds and borage.

Tomato Hornworms

Tomato hornworms are large, green caterpillars that can grow up to four inches long. They have a voracious appetite and can quickly strip your tomato plants of their leaves and fruit. You can identify tomato hornworms by their distinctive black and white stripes and horn on their back ends.

To prevent tomato hornworm infestations, try some of these techniques:

Handpick and remove the hornworms.

Encourage natural predators, such as parasitic wasps and birds, that feed on the hornworms.

Use organic pesticides, such as Bacillus thuringiensis, to kill the hornworms.

Final Thoughts

There are many pests that can damage your tomato plants in the UK, but with the right knowledge and tools, you can protect your crop. Prevention is key, so be sure to keep an eye on your plants and take action at the first sign of infestation. Whether you choose to handpick pests or use chemical treatments, it is important to prioritise the health of your plants and the environment.
