Rosehip in Latin is called Rose and, in fact, it is a wild form of a beautiful flower. There are about 400 species in the world, and there are several tens of thousands of bred varieties. Rosehip bushes are very durable, they can bear fruit for 50 years or more, and evergreen varieties live up to 150 years. The average size of a shrub is 2 … 3 m in height and 1.5 … 2.0 m in diameter. Berries contain 50 times more vitamin C than lemon fruits, so Rosehip is a valuable vitamin product. Fans of the shrub and these high vitamin berries can easily grow it from seed at home
The feasibility of growing rose hips from seeds
Plants grow from seeds with a variety of properties, sometimes unpredictable, and very different from the berry from which they originated. Therefore, it is worth growing Rosehip from seeds in the following cases:
- there is no possibility of vegetative propagation or the acquisition of varietal bushes;
- you need to get a lot of plants, while the quality of the crop is not important, for example, to create a hedge;
- out of practical interest, grow your own variety of vitamin plant.
When and how to collect wild rose for seeds?
Plants bear fruit very early. Already two or three years old bushes can produce berries. The number of berries on a bush varies greatly from year to year. Usually, fruiting maxima are observed after 3-5 years. For seeds, it is better to take fruits from bushes at the age of 4-6 years.
A lot of seeds are usually formed under the skin of the berry, which is why the fruit is called a multi-nutlet. The embryo in the seeds is very large, the endosperm is absent, and the outer shell is very thin, which is why the seeds retain their germination for only 1-2 years. A thousand seeds weigh from 6 to 6.6 g, they are very difficult to germinate.
Experts recommend picking berries, from which seeds will be selected, slightly unripe – in the second half of August, when their shell is not yet too hard. However, it is difficult for an inexperienced gardener to determine the moment when the embryo in the seed is sufficiently developed, while the shell is not yet hardened enough. Therefore, it is better to collect berries for seeds at the end of August.
Laying seeds for stratification
The harvested berries are opened without drying, the seeds are taken out and washed with water at a temperature of 37-40 ° C. Washing helps to wash off the essential substances that prevent the development of the embryo and its germination. The seed is then dried with a hair dryer set to a cool temperature. It is necessary to obtain a loose mixture, which is mixed with wet clean river sand. The ratio of sand and seeds is 3:1.
A mixture of seeds and sand is placed in a container, slightly moistened with a spray bottle, covered with a plastic bag and put away in the vegetable compartment of the refrigerator, or in a cellar or snowdrift for up to 6 months. The temperature during such storage should be constant: from 0 to 4 ° C. This procedure is called stratification, and it is, in fact, copied from natural conditions, when the seeds in the soil experience a cold time and then sprout together.
A seed is a living organism, and biochemical reactions are actively taking place in it. First of all, breathing. With prolonged cooling during stratification, the embryo activates its growth, and the seed coat becomes thinner, giving all the nutrients to the future sprout. With the onset of stable warm weather, it begins its development and forms a strong hardened plant.
During stratification, the seed bag is opened several times for ventilation, the sand is slightly mixed to saturate it with oxygen for seed respiration. If it is too dry, you need to pour the mixture from the spray bottle, and if the contents of the container are waterlogged, it is dried in the air. The main task at this stage is to prevent the seeds from rotting.
Sowing seeds of Rosehip at home
In March, the container is taken out, the seeds, if possible, are sieved from the sand and soaked in warm water for a period of 8 to 12 hours. After this time, the seeds are sown in a pre-prepared container.
For sowing, you can take plastic food containers, mini-greenhouses or shallow boxes. A layer of soil mixture of 7-8 cm is enough. Its composition for Rosehip includes garden soil, sand and peat in equal parts. Phosphorus-potassium fertilizers must be added to the substrate. A mixture of superphosphate and potassium chloride is suitable, 20-40 g of each substance per 10-liter volume of soil mixture. Nitrogen fertilizers should not be added to the mixture, as they inhibit the germination and initial growth of this plant.
Sowing seeds is carried out in rows to a depth of no more than 2 cm. It is advisable to maintain a distance between seeds of 1.5-2 cm, between rows of 3-4 cm. Grooves with seeds are covered with soil, moistened with a spray bottle, covered with a film and cleaned in a warm place.
Seed germination, subject to effective stratification, lasts 3-4 weeks. At this time, the film is periodically removed, the crops are ventilated, preventing the seeds from rotting. When the first shoots appear, the film is removed, the container is moved as close as possible to the glass in order to give the seedlings the maximum possible illumination.
At the age of 1-2 true leaves, seedlings dive. You can plant seedlings in a box according to the 5×5 cm pattern, in separate cells of the same size or larger. Further care consists of watering, loosening , and fertilizing with potassium humate every 14 days. At the end of May, if the plants are already strong enough, they can be transferred to open ground, or they can be planted on the site in September.
