Before moving on to the description of the distinct techniques, let’s review some common details of this step of plant preservation:

Once the plants have been harvested, following the directions for sustainable and safe harvesting, prepare them for drying as soon as possible. Leaves, roots, fruits and flowers could easily rot or spoil if left for too long in closed bags or piled up.
Before setting them out to dry, shake out branches and leaves and check each part of the harvested material thoroughly to make sure there is no soil residue or pests. The plant should look healthy and clean.
It is not recommended to wash the harvested plant material as it may alter the preservation process and encourage the growth of mold.
If you have any doubts about the origin and health of the plant, the advice is to avoid preserving it.

These rules are always valid, whether you use the plant for the preparation of macerated or infused oil or for the preparation of your dishes.

Let’s now focus on the 3 drying techniques. They are all valid and, if done correctly, guarantee excellent results.

Drying technique no.1: Natural drying

This is the most traditional technique, suitable for drying plants with branches and leaves, such as rosemary, thyme, basil, etc. It consists in making small bunches to be tied with kitchen string at the base, being careful not to tighten too much in order not to damage the branches and to allow air to circulate and dry the plant uniformly. Bunches should be hung with the leaves facing downwards, in a dry and airy place where direct sunlight does not reach. With this technique, drying times vary from 7 to 20 days depending on the type of plant.

Drying technique no.2: Natural drying second way

Another option consists in disposing the collected material on clean kitchen towels or in special baskets made of wicker or similar materials. In the second case, it is important that the basket (or container) is wide enough to allow the passage of air. It is advisable to change the position of branches, roots, leaves or flowers every 2-3 days, in order to make the drying process more uniform. Times, also in this case, range from 7 to 20 days.

Drying technique no.3: Drying with the use of a oven

If you do not have much space available and prefer faster techniques, using an oven might be the most suitable technique for you. Plants are spread on a baking pan covered with baking paper and are dried at a temperature of 40-50 degrees centigrade (104-122 degrees fahrenheit). Plants are spread on a baking pan covered with baking paper and are dried at a temperature of 40-50 degrees. During this process it is advisable to keep the oven door slightly open, so the temperature is always under control.
