Chervil is one of those herbs that readily self-seed. This means that you will be easily able to find chervil seeds from someone who already grows chervil. If for some reason, you can not find the seeds, you will have to purchase a seedling. However, successfully growing chervil from a seedling is difficult because of the fact that this plant does not transplant well.
Loam is ideal for growing chervil. Furthermore, the garden area in which you plan to grow chervil should be shaded from direct sunlight and the patch of soil you use should be well drained but should moist at the same time. If you do not have a garden or a lawn, you can grow chervil indoors in a clay pot.
Depending on the time of year in which you want to use chervil, choose the appropriate sowing time. For use in the summer season, you will need to sow chervil seeds early to late spring. However, for use in the autumn season, chervil seeds will need to be sown late summer. Sow the seeds shallow and cover them with a fairly thin layer of soil. To start and promote germination, you will have to keep the soil moist for most of the time.
Wait for the seedling to start growing. When that happens, you will have to thin them out so that they are spaced 10 inches apart.
Be sure to keep the soil consistently moist. However, do not let water form a pool because it might rot the plants. Use a water can for this purpose. Moreover, consider occasional use of soluble, nitrogen-rich fertiliser for speeding up growth.
Allow about 6 to 8 weeks for the leaves to ripen and become rich in flavour. After the aforesaid time, you can harvest chervil leaves from the plants and use them in your recipes.
