Flower seeds: how to choose them
The laying of the seeds of the flowers is an easy operation, as long as you respect the times and modalities foreseen for each species. Many of the perennials and flowering annuals that can be grown in the garden, in particular, are easy to propagate by sowing, and for this reason they guarantee the opportunity to count on varieties and colors that would be difficult to find in the nursery. Getting flowers from seeds is not difficult: let's see how. First of all it is good to specify the importance of using high quality seeds. Keep in mind that almost all flowering plants that are grown in the garden are nothing more than hybrids of different species: this means that starting from the harvested seeds, slightly different plants derive, in terms of color, shape or size, compared to the plant that has originated the seeds. Conversely, specialist seed producers are able to obtain all the same plants from seeds. The objective, in any case, is to focus on reliable traders, who will ensure that the future appearance and structure of the seedlings will correspond to what we want. In short, if we want a flowerbed made up of orange violets, we must be sure that, once they are born, the violets will not have a thousand different color shades. Clearly, often the best quality seeds are a little more expensive than the others: but it is a minimum economic sacrifice that is worth confronting with respect to a safe seeding outcome. Of course, nothing prevents you from buying the seeds without a specific criterion, in order to get a multicolored effect: don't forget, however, that it could happen to obtain simple flowers starting from sachets for double flowers, or in any case of various kinds of misunderstandings.
The importance of planting
For the planting of the seeds of the flowers it is also fundamental the soil, which should be preferably soft and above all able to preserve the humidity. In general, shredded peat is used, mixed with sand in equal parts: the mixture must be moistened before sowing. Always before sowing, it would be preferable to use perlite or vermiculite, light inert and rather light inert materials that protect the seeds from drought and insects. It is sufficient to cover the seeds for safe results. Almost all flowering plants are sown without problems directly at home. The space must be prepared in spring, when even at night the temperatures approach fifteen degrees. Working the soil with rake and hoe, it is necessary to obtain a soft and smooth surface; therefore, you can water the flowerbed and continue sowing it with a broadcaster. It is good to avoid leaving areas that are too bare to the detriment of excessively dense areas: in short, try to spread the seeds evenly.
Keep the soil moist with perlite
Once sown, the soil must be kept moist until the seeds germinate completely. If we intend to prevent the layer of substrate on the surface from becoming dry, we can use vermiculite and perlite again, which will keep the soil moist without depriving the seeds of sunlight. As a rule, plants with a rather delicate root system are sown in the ground: this is the case, for example, of nasturtium or escolzia. In any case, all the plants that naturally surround our garden can be planted directly and sown in the ground.
Flower seeds: the seedbed
On the other hand, there are species that can be sown exclusively in seedbeds: it is a method that allows to have the plants prepared already in the first weeks of the year, which obviously would be impossible if the sowing took place in the garden, given the very low night temperatures. Thanks to the seedbed, moreover, already in winter it is possible to prepare perennial or annual plants that in nature would not be adequate for our climate (for example the species that come from Africa or South America, which need - to germinate - to high temperatures): in spring, in short, there will be already developed plants that could not have been obtained in any other way. The seedbed is nothing more than a container of soil inside which sowing takes place. Usually small vessels with a diameter that does not exceed ten centimeters are used; but there are also rectangular trays without holes, or seed trays with multiple holes. Furthermore, these containers need the pots, so that the soil can be wet without the water coming into contact with the seeds. A mixture in equal parts of peat and sand will fill the container, which will then have to be placed in the saucer and constantly wet, so as to ensure the moisture of the compound. As far as sowing is concerned, one or more seeds must be placed in each hole according to the species. The seed must be pressed firmly so that it can adhere to the surface of the substrate without problems: after that, it must be covered with a layer (two at most) of perlite or vermiculite.
