Properly store and send seeds & seeds Whether for the distribution, preservation or breeding of new varieties: The harvesting of seeds is one of the most important species of plant propagation both in agricultural practice and in private gardens. Seeds save space and can last longer periods of unfavorable environmental conditions. An extreme example is the seed of a magnolia found in a burial chamber near Tokyo in 1983, which, despite its estimated age of about 2,000 years, produced a magnolia tree.
Of course, this find is an exception. But with proper storage, seeds can be kept very long.
The right preparation
Seeds are as different as the plants from which they come. Depending on the type of distribution ranges from the dusty seeds of the orchids to the kilo-heavy fruits of various palms. Accordingly, the storage designed.
Seeds, which are surrounded by a lot of pulp (for example, various types of vegetables and fruits, fuchsias, cacti), are as free as possible from this and for drying - designed for example on kitchen paper or coffee filters
- Pulp may be rinsed in the strainer under running water or peeled overnight in a water bath (e.g., zucchini, melon)
- In the case of cucumbers and tomatoes, the pulp may be fried in a water bath for two to three days before being rinsed off
For storage, the seeds must be completely dried. Damp seeds mold very quickly and become unusable. If the collected seeds do not dry sufficiently due to high humidity, they can be placed on newsprint paper in the sun or near a heater, for example. Silica gel (available, for example, in pharmacies) can also be used for drying.
Containers for storage
When the seed is completely dried and free of plant and soil residues (e.g., by sieving), it is transferred to suitable containers. These should be as airtight as possible. Suitable containers with tight-fitting lid. If these have not already been incurred in the household (washed-out cans, jam jars, etc.), you can order cost-effective variants in all sizes on the Internet. For very fine seeds, for example, Use centrifuge cups (capacity 2ml), from which the seeds can be removed again with virtually no loss. For somewhat coarser seeds, screw caps are used in industry as containers for sample storage. It is also possible to package the seeds in small sachets and collect them in larger containers (e.g., tupper cans). Important: do not forget to label the containers with name and year of harvest. In spite of best intentions, one usually forgets very quickly which seed belongs to which plant.
The storage location
The optimal storage location is cool and dry. Temperature fluctuations, e.g. by direct sunlight, are to be avoided. Many seeds can also be stored deep-frozen. As a result, germination can be maintained over very long periods of time (decades). In addition, frost germs anyway need the low temperatures in order to germinate successfully later. If storage in the freezer is designed for very long periods of time, it may be useful to portion the seeds to avoid thawing again.
An important advantage of seeds over living plants is the ease of shipping by post. Especially small seeds fit - packed properly - into a standard letter. For shipping, paper or plastic bags are best, which are best stuck in the envelope so that they do not slip. Larger seeds should be shipped in matchboxes or other sturdy containers so they will not be crushed by the postmark.
Thus, the exchange of seeds - at least as long as no conflicting aspirations of the EU are realized - nothing in the way.
