How to grow and maintain a good crop of root celery?
Real vegetable growers strive to expand the range of vegetable crops grown and are not limited to the usual cucumbers and tomatoes. Increasingly, in summer cottages you can see celery, which has become especially popular in recent years. Celery has long been considered the talisman of farmers. The ancient Greeks awarded celery wreaths to the winners of sports games.
As an edible garden plant, it began to be used only in the Middle Ages, and at the same time it appeared and spread in Russia, but it was used only for decorative purposes. Only in the 18th century did it begin to be used as a food crop. Celery is a very healthy vegetable, and absolutely everything - from the root to the leaves and even the seeds, is edible.
Plant characteristic
Celery exists in three types: leaf, root and petiole. This is a biennial plant, in which a ground green mass is formed in the summer of the first year, and a root is formed in autumn. Only in the second year does it bloom and form seeds.
Description
Celery belongs to the category of herbaceous plants, to the umbrella family, and can reach a height of one meter. The grooved celery stalk is straight and branched.Large openwork-pinnate lower leaves of a rich green color, and the upper leaves, cut into lobes (from 3 to 5), wedge-shaped from above, incised and serrated, form a rosette and are very similar to parsley leaves. Small flowers of light green color form an umbrella. Gray, and sometimes with reddish streaks, the fleshy root crop has an irregular round or oval shape, thick roots extend from it.
All parts of celery contain an essential oil that contains 86 different compounds that give it its characteristic odor. The whole plant is equally rich in vitamins C, B1, B2, folic and chlorogenic acid, and includes up to 10 amino acids. With a low calorie content (100 g of the plant contains only 13 kcal), it has a high content of fiber, minerals and trace elements.
Difference from other species
The main distinguishing feature of the three types of celery from each other is which part of the plant is the most developed: leaves, stems, petioles or root. Another distinguishing feature is the speed of growth of greenery after cutting and the size of the root crop.
Unlike petiole and root, leaf celery has neither a large root nor thick stems. He appreciates the abundant above-ground green mass. Most often, its leaves are seasoning for various dishes. They are rich in many useful substances and vitamins.
Petiole celery can grow up to 50 cm tall. In different varieties, its petiole stems can be, in addition to green, also light pink and even white. Its stems can reach a thickness of 5 cm, and the root does not develop. Its most valuable are juicy stems, which have a delicate unobtrusive taste and a pleasant delicate smell.It is consumed both fresh and used to prepare various dishes.
Root celery, unlike the other two, has a fairly large root that can reach 10 cm and even 20 cm in diameter, although its above-ground greens are not too high. A fleshy and juicy root vegetable with a spicy bittersweet taste can be eaten fresh, as an ingredient in various dishes, and served as a side dish.
Varieties
The variety of varieties of this plant is represented by both foreign and Russian breeders. Domestic varieties "Russian Size" and "Anita" have proven themselves well. Given the Russian climate, the most suitable varieties for cultivation are early ripening varieties with a growing season of about six months. The most famous and widely grown varieties:
- "Apple" - seeds of the earliest ripe variety. With proper agricultural technology, the ripening period can be about 3.5 months. The variety has fruits of not very large sizes, round in shape, with a high content of sugars, which gives it a sweet taste with a delicate smell. Has a long shelf life.
- "Prague Giant" from imported manufacturers. Also applies to early varieties. The ripened root crop reaches a fairly large size, its delicate light pulp is characterized by good taste.
Among the mid-season varieties can be called "Gribovsky", "Diamant", "Cascade", which ripen from 120 to 150 days. The Gribovsky variety has a medium-sized fruit with golden spotted flesh. In "Diamant" the root crop is larger, but also with delicate white pulp.
Of the late varieties, the ripening of which occurs from 170 to 200 days, one can note such as:
- "Giant" - the champion of root celery, its root crop can reach a weight of 700 g.
- "Maksim" - the most late-ripening variety. It takes 200 days to mature. Its fruit is distinguished by the fact that it forms many additional roots from the sides, their weight reaches 500 g. The pulp is tender, with a pleasant smell and a slight sweet taste, and has an ivory color.
There are also such varieties: foreign "Snowball", "Jupiter", Russian "Egor", "President R3", "Golden Pen", "Delicatessen" and many other varieties.
Growing conditions
Growing root celery is not so difficult, but certain conditions are required.
Place and soil
Places inaccessible to strong winds, but with good sunlight will be favorable for celery. Being a moisture-loving plant, it grows well in places where moisture is kept in the soil for a long time, but areas where groundwater is close to the surface of the earth should be avoided, which can lead to root rot. The root celery prefers soil that is not heavy, fertile, with a high content of minerals and a certain level of acidity.
Before planting celery in the ground, it is strongly not recommended to fertilize the soil with manure, as this will lead to spots on the root.
It brings high yields on chernozems, floodplain, loamy soils. However, experienced vegetable growers can easily grow celery on loose, slightly acidic soils, even in partial shade.
Temperature
There are no special requirements for the temperature regime of root celery, however, the optimum air temperature is at least 15 degrees Celsius and above, so it is also successfully grown in moderate climatic conditions.Autumn frosts are not terrible for root celery, it can easily endure slight frosts (from -4 to -6 degrees), but in spring the seedlings will suffer from the cold and in the future the root will not develop, but will form a shoot with a flower, and then seeds.
illumination
The duration of sunlight also plays a role. Celery loves sunlight and prefers long-term lighting, but easily tolerates partial shade.
Humidity level
Celery root requires high humidity, but water should not be allowed to stagnate on the soil, as this entails a decrease in plant resistance and the risk of fungal and viral diseases. The optimal humidity level for celery is about 70%.
Suitable "neighbors"
It is recommended to grow this plant in the old beds only after four years. You can not plant it after carrots and greens - parsnips and parsley, and cabbage, potatoes and cucumbers are desirable predecessors. The "neighbors" of celery can be tomatoes, lettuce and spinach. It can also be planted alongside bush beans, beets and chives. It is good to grow it between the beds of neighboring crops, as its specific smell repels harmful insects.
Selection and preparation of seeds
For central Russia, celery can only be grown in seedlings, since the time of the vegetative formation of the root crop is quite long. In order for the seedlings to turn out to be of high quality, you must first of all select the seeds and prepare them for planting. The right choice of seeds is the key to a rich harvest. It is preferable to buy seeds of early ripe and large varieties of root celery, given the Russian climatic conditions.
You can not buy seeds with an expiration date, because over time they lose their ability to germinate.
Before sowing seedlings, the seeds must be prepared. Preparation and further sowing on seedlings must be done in advance, starting from the first decade of February to mid-March. Seedlings will stretch and fruit growth will slow down if the seeds are planted earlier, and if you do it later, the root crop will not ripen for harvest.
Celery seeds contain a large amount of essential oils, which slow down the process of swelling and germination in the soil. With insufficient moisture, this process can take up to three weeks and produce few shoots. Seed preparation is needed to remove essential oils from them. There are several ways to prepare:
- The simplest is soaking the seeds for a short time (2 days). You need to change the water three times a day. After the seeds are dried, and they are ready for planting on seedlings.
- Pour the seeds into a container with hot water (60 degrees), mix them vigorously for several minutes. During this time, essential oils should go into the liquid. Seeds, after the water has cooled, rinse with cold water. The water is drained, the seeds are dried.
- The most reliable method is seed germination. The seeds placed in cloth bags are dipped in water, the temperature of which is about + 50, for 20 minutes, then they are quickly immersed in cold water for the same period. After the seeds are placed on a wet cloth, spread over the entire surface, and taken to a warm room for germination.
- A more complex method is seed bubbling.The seeds are placed in water for 24 hours and bubbling is done using an aquarium compressor, after which they are poured for an hour with a 1% solution of potassium permanganate, then with a solution of epin in the proportion of 2 drops per 100 ml of water and kept for 20 hours. Only following this sequence will lead to good seedlings.
- Some vegetable growers use the method of soaking seeds in vodka. Seeds in cotton fabric (you cannot use gauze) are dipped in vodka for a quarter of an hour. Then they should be thoroughly rinsed with warm water and dried.
Prepared by one of these methods or germinated seeds are ready for planting in the ground for seedlings.
seedling care
Growing seedlings of root celery is not a quick process and includes several stages. The main thing in this process is sowing seeds and properly organized care for seedlings. The soil is prepared in advance for sowing. You can buy ready-made soil or cook it yourself. You can prepare such a nutrient mixture: peat - 6 parts, humus - 2 parts, soddy soil - 1 part and sand - 1 part. Urea - 20 g, and ash - 1 cup are added to the resulting mixture for every 10 kg.
Having filled the container for growing seedlings with soil, you can sow the seeds. The soil is moistened, furrows are made at intervals of 5 cm, compacted and seeds are sown at the same distance (3-4 cm) from each other. Planting depth should be no more than 0.5 cm.
The best containers for growing seedlings are special small pots (5 cm). Two-thirds of these pots are filled with earth, pressed down and moistened, and 3-4 seeds are sown in them.
You don’t need to cover it with earth from above, just cover it with polyethylene and place it in heat.
Planting celery seeds in the snow is effective. Snow is scattered along the furrows with a layer of 2 cm thick, lightly pressed down and seeds are planted. Snow, melting, will immerse the seeds to the required depth, while it is not necessary to cover the seeds with soil. The container is covered with polyethylene or glass and placed in a room with a temperature not lower than +20 degrees.
Seedling care is to provide it with optimal temperature, good lighting and proper watering. The most important for celery seedlings will be the first thirty days after sowing. During this period, a stable temperature of +15 ... +20 degrees is maintained and seedlings are aired daily, for which polyethylene is removed for a while.
Humidity should not exceed the norm. It is impossible to water the seedlings excessively, since with an excess of moisture, black leg disease occurs. Watering is carried out as the soil dries. It is better to do this using a spray gun, so as not to harm weak shoots. Water should be used separated by a temperature of 18-20 degrees.
Before germination, the seeds do not require lighting, so the container with seedlings is placed in a warm and dark room. After 10-15 days, the first shoots may appear that need good lighting, so the seedlings are transferred to a bright room. In February, it must be additionally illuminated in the morning and evening hours for 3-4 hours, and from March - for 2 hours a day.
Picking is done in the phase of the appearance of true leaves and again a month after sowing. When picking, the main root is cut off by a third to stimulate the growth of the root crop, the plant is transplanted into a larger container. Seedlings are planted deep into the soil to the first two leaves, but the top of the shoot should be above the soil level.
With proper care, by April, celery will be a strong and developed plant.From this moment, the seedlings are hardened off, putting it in a colder room and increasing the time it stays in the cold every day. Further care of seedlings is simple: the room should be cool and light, it is important not to allow the soil to dry out. Quality seedlings have 3-4 strong leaves and a height of about 17 cm.
Landing in open ground
The soil for planting celery is prepared in the fall. The beds are dug up well, weeds with roots are removed, organic (well-rotted compost) and mineral fertilizers are added to the soil. If the soil has not been prepared in the fall, then this is done in the spring:
- in advance, for two or three weeks, they dig up the earth to a depth of about 30 cm;
- the soil is disinfected with a solution of vitriol or manganese;
- the soil is fertilized with humus and complex fertilizers - nitrofoska or azofoska.
To keep warm, the prepared beds are covered with polyethylene.
Timing
The exact timing of planting seedlings does not exist, it all depends on climatic conditions. When the threat of frost has passed and the weather is warm, you can plant seedlings in open soil. Most often it is the 2nd or 3rd decade of May. The best period for transplanting is a cloudy, non-sunny day or evening.
Landing pattern
Celery seedlings can be planted in two ways:
- Private. Seedlings are planted at a distance of about 30 cm in rows, and between rows the width should be about 60 cm.
- Line-tape. There are 4-5 lines (rows) in the tape, the distance in the lines between celery is up to 20 cm, and between the tapes is about 60 cm.
When planting seedlings, adhere to the following rules:
- prepared wells are watered with settled water;
- when transplanting seedlings, it is impossible to destroy the soil lump;
- seedlings cannot be planted deep into the ground and care must be taken that the top of the shoot is above the soil level;
- transplanted seedlings need to be watered again.
The nuances of agricultural technology
To grow high-quality root crops, you need to regularly care for them, observing the following rules of agricultural technology:
- Watering. All the time of growth, the soil must retain moisture, so watering does not end with the onset of autumn. The frequency of watering is once every 2-3 days, depending on the weather. Daily watering is needed on hot days. The water consumption rate is 5 liters per m2. With proper watering, water does not stagnate, but provides soil moisture.
- Weeding. A prerequisite for caring for celery is regular weeding. To delay the growth of weeds, mulching is used, which also has another effect - it retains moisture in the soil.
- Loosening. Loosening and weeding are done simultaneously, at least 1 time in 14 days. Without loosening, the soil is covered with a dense layer. Loosening it destroys and promotes the penetration of air and water to the root. The depth of loosening increases as the celery grows from 5 to 10 cm.
- Top dressing. According to experienced gardeners, you need to feed celery at least 2 and no more than 4 times during the growing season. The first time he is fed two weeks after transplanting the seedlings, and the next feeding is a month later. There should be more potash in the composition of fertilizers, which contributes to the good growth of the root crop. Mineral fertilizers containing sulfur and sodium are also effective.
Organic fertilizers are very useful, especially weed infusion, which is fed to the seedling at the beginning of growth.
At the middle stage of plant development, it is better to fertilize with a solution of chicken manure or mullein, and closer to autumn - with superphosphate, ash or boron.Method of preparation of herbal infusion: weed grass is placed in any container with water and aged for 14 days. When using such an infusion, you must strictly adhere to the ratio of 1 part of the infusion to 10 parts of water.
- Removing lower leaves. If cracks appear on the stem or it begins to dry out, then it must be removed. Extra leaves are also removed. About 5 stems with leaves should be left in the outlet.
- Removal of lateral roots produced when the root crop noticeably increases in size. Cutting is done carefully with a sharp knife.
- Raking the soil around the root crop. Hilling the root crop is strictly prohibited. On the contrary, the soil must be constantly raked from all sides. This must be done so that lateral roots do not develop. Their development leads to a deterioration in the taste of the fetus.
Collection and storage
With the onset of autumn, the moment of harvest becomes important. It is necessary to have time to remove it before the first autumn cold. Most often this is the beginning and middle of October. It is not recommended to harvest earlier, since the accumulation of nutrients and good root development occurs in the fall.
It is necessary to harvest the crop in non-rainy weather. To facilitate digging, you can slightly moisten the soil. In this case, care must be taken not to damage the skin of the fruit. After harvest:
- cut off all the roots of the fetus;
- all leaves to the base must also be cut;
- hold the root crops in the beds for some time to dry;
- after the harvest is taken to the storage room.
There are no special rules for storing celery in winter. It can be stored in a cellar in a container with sand. The sand must be clean and damp. The root is immersed in it by a quarter. As it dries, the sand is moistened.
