If you want to get started in learning how to harvest chervil, you need not worry about spending hours doing research. The truth is that understanding how the process is best done consist of only four basic steps.
Step 1 on how to harvest chervil: do it at the right time
This would be about one and a half to two months after you have planted the herb. By this time, the leaves will have gotten the right amount of flavor needed. Picking them too early is not recommended as the flavor will just not be there. Also, you should pluck the leaves in the morning before the sun dries it up. Be careful not to take away everything, and leave at least a third.
Step 2 on how to harvest chervil: store it wisely
This is best accomplished by taking the leaves you are not going to use yet and put them inside a container filled with water. Next put the bottle in a plastic bag and put in the refrigerator (not freezer). However, it is best if you are going to use the herb right after you pick it, because the flavor will be at its strongest.
Step 3 on how to harvest chervil: freeze if long term storage will be done
Chervil is best for immediate use, but it is possible to store it for half a year. The way to do this is by again placing the leaves in bags (plastic preferable), and storing the herb in the freezer. As with other herbs, you may add some butter to help keep the flavor intact.
An alternative method is to utilize a dryer (commercially available) and keeping it in a container. Using this method will allow you to keep the leaves edible for a year.
Step 4 on how to harvest chervil: tend to the plant always
This is something that needs to be done if you want to keep a constant and steady supply of the herbs. The quality of the leaves that you can get will depend on how well you tend to it, so you should not just care for the plant before you harvest but also afterwards.
Although with a reputation for being difficult to plant, the fact is that learning how to harvest chervil is not that hard and is in many ways similar to storing and using other herbs. All it takes is a little patience.
