Watering - Make sure the plants get 1 inch of water every week from rain or by watering.
Fertilizing - Chervil is a light feeder, so it needs no supplemental fertilizer over and oabove the one application of slow-acting fertilizer in the spring. Excessive leaf growth reduces the flavor of those leaves. You can spray plants with liquid seaweed extract two or three times during the growing season which works like a tonic.
