Chervil acts as a barrier plant to protect your cannabis plants from against unwanted pests. Grown in a guild with Dill and Coriander around your cannabis plants will protect them from Aphids and Whitefly. Aphids and whitefly are repelled while attracting honeybees and parasitoid mini wasps that feed on the larvae of hostile insect species. Chervil is a shade-loving plant and dislikes being potted on and should be sown directly into the garden. Sprinkle the fine seeds in a shallow furrow and water in well. Within 2 weeks from seeding, the sprouts will need some thinning. Around week 6 it will be ready for use. It grows only about 60cm tall, so it is recommended to continually pluck and top the plant to delay flowering and encourage a healthy growth.
