Rainbow Chard pests — FAQ
What is eating my rainbow chard?
Rainbow Chard 'Bright Lights' faces the same pest pressure as all Swiss chard — beet leaf miner, aphids, slugs, and occasionally caterpillars. Its colourful stems do not confer any pest resistance. The edible leaves are the economic part, so even moderate leaf miner damage warrants prompt action. Fine mesh exclusion is highly effective.
