Growing Raspberries from Seeds: Planting and Care Tips
Most often, raspberries are propagated by cuttings, which is the fastest way to obtain seedlings. Growing raspberries from seeds is a more complex and time-consuming process. To get a good result, it is important to know all the features of planting seeds, and following the rules for caring for shrubs will improve the yield of raspberries.
What is this berry?
Raspberries belong to the type of shrubs. The height of upright stems can reach 2.5 meters. The root system is quite powerful, it grows not only deep into the soil, but also in width. Berries are a number of drupes that are fused to each other in the upper wide part of the pedicel. The fruits of the plant look like truncated cones, but may also have a different shape (depending on the species) - for example, more rounded.
Raspberries have a good sweet taste with a slight sourness. Berries can be consumed both fresh and processed. The fruits are widely used in cooking and food industry - for the preparation of sweet products.
In folk medicine, berries are used as an anti-inflammatory and antipyretic agent. Raspberry seeds are also used to make oil, which is used in cosmetology for facial skin, hair care, and also as a protective agent against sunburn.
How to grow seedlings?
Growing raspberries from seeds is a rather laborious process.If you do not follow all the rules, seedlings may not grow at all. An important step in this case will be the preparation of seeds for planting.
Seed extraction
Seeds can be obtained independently (from the fruits of raspberries, which are already growing on a personal plot) or bought in a store. Before buying, it is important to choose the right raspberry variety. When choosing, it is necessary to focus on the climate in the region where the shrub will grow.. However, store seeds are not always of good quality, so it will be more reliable to reproduce already growing shrubs.
At home, the seeds can be extracted from the berries themselves, but this process must be approached with extreme care, as the grains are easily damaged. Planting material is obtained only from well-ripened or overripe fruits.
The collected fruits must be inspected: they should not have defects. Rotten berries are not recommended for seeds. Pure and whole raspberries must be rubbed through a sieve or squeezed through cheesecloth. As a result, the juice will separate, and the cake will remain. Seeds are obtained from it.
To separate the planting material from the pulp of the fruit, the resulting cake must be placed in a container of water. For seedlings, it is necessary to use only those grains that remain at the bottom of the container. Planting material that has surfaced is not recommended for planting. Selected seeds are kept in water for a day (for swelling).
The second way to extract the grains is to dry the cake. Waste is distributed on a sheet of paper or laid on a clean cloth in a thin layer. Drying is recommended to be carried out in a place protected from direct sunlight.When the mushy mass dries a little, seeds can be easily removed from it.
Training
If you are going to start planting seeds, they must first be stratified. This process involves the creation of certain storage conditions for the grains, which will accelerate their germination after planting in the ground. In this case, it is important to monitor the temperature and humidity levels.
Grains that have previously been separated from the pulp of berries and aged in water must be placed in a small cloth bag or wrapped in gauze. A bag of seeds should be slightly moistened with water, placed in a box and overlaid with moss on all sides.
The box is removed for storage in a dark place (until mid-spring). It is necessary to periodically remove the planting material and moisten it. Alternatively, you can mix the seeds with wet sand and place everything in a box.
The box for the winter is buried in the ground to a shallow depth. The layer of earth above the seeds should be approximately three centimeters. When choosing a place for burying seeds, it should be borne in mind that in winter there should be a large amount of snow in this area.
Seeds can be stored in the refrigerator, at a temperature of 0 to 5 degrees. The bag with planting material needs to be moistened periodically. Landing in the ground after storage in this way is carried out in April.
Germination
Sowing of prepared planting material can be carried out in mid-spring. To sow the seeds correctly, you must first prepare the soil. The earth is dug up, loosened, fertilized and moistened. It is not recommended to strongly moisten the soil, as raspberries do not germinate well in too damp soil.
Seeds are planted at a shallow depth (about three centimeters). The bones are buried with a pre-prepared mixture, which consists of soil, sand and humus. Raspberries from seeds can sprout unevenly. The first shoots usually appear in late spring. When the shrub begins to germinate from the seed, and a couple of leaves appear on the surface of the earth, the seedlings can be planted.
Young shoots are recommended to be placed in a greenhouse in previously prepared soil in order to germinate them before planting in a permanent place. In the greenhouse, the plant needs care.
Watering should be regular and carried out at intervals of six days. Sprouts require weeding, as well as treatment for diseases and pests.
How to plant?
Shoots in the greenhouse are gaining strength by autumn, after which they can be planted in the garden. When choosing a place for planting shrubs, it is important to consider that raspberries are a light-loving plant, so the site should not be in the shade. Planting shrubs in a temporary place is most often carried out in one or more rows. The distance between rows is usually about 40 centimeters, and between adjacent shoots - at least 15 centimeters.
Raspberries need regular watering, the frequency of which depends on the climate in the region. It is important that in the summer the soil is never dry. To preserve moisture in the soil, it is recommended to cover it with sawdust or hay mulch.
The last transplantation of shoots is carried out at the end of summer or at the beginning of autumn. The selected area is recommended to be dug up and fertilized. Seedlings are placed in holes, the depth and diameter of which must be at least 40 centimeters. It is recommended to fill each hole with sand and fertilizer.
The distance between the rows of raspberries should be at least 50 centimeters. It is recommended to install trellises on the site in advance so that actively growing shrubs can be tied up in a timely manner.
Care Tips
Judging by the reviews of experienced gardeners, it can be noted that caring for raspberries is not particularly difficult. The shrub requires regular watering during the period of active growth, from mid-spring until the onset of cold weather. With insufficient moisture, raspberries do not bear fruit well, and its yield can be reduced by three times.
The shrub regularly has new shoots. In order for the plant to grow and develop well, old or weak branches must be cut off. For one season it will be enough to carry out one pruning. This procedure is carried out in the middle or at the end of spring. About 7 stems must be left per bush.
In regions with cold winters, it is recommended to bend shrubs to the ground in autumn. A kind of hat made of branches will serve as a protective layer against freezing of the root system. A trellis system is used to tie the shoots. Tapestries will also be required in the spring to tie up already straightened branches.
top dressing
It is recommended to fertilize raspberries after the complete disappearance of snow. Usually, from mid-April, the soil is already ready for fertilization. As a top dressing during this period, you can use urea or ammonium nitrate. About 100 g of fertilizers are taken per square meter of a plot with plantations.
At the stage of active shoot growth, it is recommended to add fertilizers of organic origin to the soil. For these purposes, you can use cow dung or chicken manure. Organic fertilizers are pre-mixed with water (1 kilogram per large bucket of liquid). The resulting composition is abundantly watered shrub.
When the first fruits appear, it is necessary to fertilize with mineral phosphorus fertilizers. In this case, about 50 g should be spent per square meter.
Treatment
To prevent the development of shrub diseases and to protect against insect pests, the plant must be periodically treated with special compounds. Processing is carried out about a week before the appearance of flowers.
Copper sulfate is used to protect against the spread of fungal diseases. The agent is distributed along the branches and added to the soil around the bush. Previously, copper sulfate is diluted in pure water (100 g per 10 l).
Raspberries are often attacked by insect pests, which negatively affects the growth of shrubs and yields. Pest control is carried out with special formulations that can be purchased at gardening stores.
