Materials needed to create a herbarium
To begin creating your herbarium, you will need:
• Freshly harvested plants!
• For sampling: a small pruner, a pair of scissors, a small shovel, a notebook, a pencil;
• For drying: newspaper or blotting paper, a press (which can be replaced by large books);
• For gluing: gummed paper, if not, white glue or self-adhesive paper (avoid scotch), a small forceps to facilitate handling;
• Support the herbarium: large sheets of relatively thick paper (160g / m2 A3 is ideal either 29,7x42cm) to classify and store in folders, or even a large spiral notebook (at least 24x32cm ), but then the classification can only be chronological;
• A hermetic box to store your herbarium away from moisture, light ... and insects too greedy!
The harvest
If you decide to look for plants in the wild, it would be better to do it in dry weather to facilitate the next step of drying! However, pay close attention to the location of your picking to avoid any protected plant or specimen that has managed to grow on new land. For this, choose a place where the specimen is present in several copies! Once you have found the right place, you can cut the plant and transport it carefully in a small plastic bag or crate.
How to prepare
In practice, what part of the plant to collect and present in a herbarium? Purists will harvest, whenever possible, the entire plant, that is to say with the root system (hence the usefulness of a small shovel to be able to tear the plant without breaking the roots too much) , flowers and / or fruits (or cones, sporangia, etc.).
If the purpose of the herbarium is merely decorative or playful, you can choose to focus on a part of the plant, the one that you think the aesthetics or the most representative: leaf with petiole, flower, stem with leaves ...
It is important to harvest the plant in dry, preferably in the afternoon, when all trace of dew has disappeared: the less moisture at the time of sampling, the better the chances to do well drying!
How to realize
Once home, it's time to take care of the drying phase. Plants are placed between sheets of newspaper. Then, between each page containing a plant, place several blank sheets of newspaper. For more ease, we invite you to cut your plants to the size of your herbarium! To achieve optimum drying, place a heavy object on the set. Then let your flowers dry for about a week in a dry, dark place. Oven drying allows you to speed up this step.
The composition of your herbarium
Finally your plants are ready to be arranged in your herbarium! You will be able to opt for a simple notebook, know however that special books exist and propose a texture of leaves different for a better conservation. You can use a suitable glue or small pieces of tape to fix your plants. To make this activity even more fun, you can add to the pencil the name of the plant and the day and place of the harvest. Little trick: cover the pages with clear plastic sheets to protect the plants during handling.
