How to plant and grow radishes?
Radish is a fairly common crop in cottages and gardens. The popularity of the root crop is associated with its unpretentiousness, fast ripening time, the ability to plant at any time, and in addition - exceptional taste, nutritional value and usefulness. This is an indispensable vegetable in the spring, the fruits of which can be enjoyed even when other plants are at the stage of growing seedlings.
Peculiarities
Radish, like its cousin cabbage, belongs to the cruciferous family, the most popular are annual species that produce usable fruits and seeds in the first year of planting, but many prefer biennial varieties - they form roots in the first season, but seeds can be harvested only for the second. This type of plant is quite rare for the European part of Russia and is mainly distributed in Asian countries and republics.
Usually radish roots have a rounded or slightly elongated shape, the color is pink, red, less often purple or white.
Radishes can be grown outdoors, or seeds can be planted in a polycarbonate greenhouse.
Consider the most popular varieties of radishes.
- "18 days" - super early variety. The fruits are cylindrical, light pink in color. The tail is white, the flesh is white with a dense structure. Taste is mild.
- "Heat" - a variety of early maturation, the crop can be harvested already 3 weeks after planting the seeds. The fruits have a flattened red-crimson color. The taste of radish is slightly spicy.
- "French Breakfast" - another early ripe variety, which also produces ripened fruits 21-23 days after sowing, the taste is slightly spicy.
- "Carmen" - you can enjoy these fruits already on the 20th day after planting. The fruits have a rounded shape of red color, the taste is light, slightly spicy.
- "Cardinal" - This is a mid-season hybrid variety. The fruits are round in shape, the skin color is red, the flesh is white, dense.
- "Red Giant" - a mid-season type of radish, the fruits are formed after 30-40 days, the root crops are quite large - the mass of each can reach 150 grams. The skin is red and the flesh is light pink.
- "Octave" - fruits can be obtained 1-1.5 months after planting. The fruits are rounded, white in color, the internal structure is dense without voids. The taste is mild and spicy.
- "Red Giant" - a variety of late ripening, the fruits of which are quite impressive - their weight often reaches 300 grams. The skin is pinkish, and the flesh is white, the taste of the vegetable is spicy.
Many summer residents prefer the "18 days" variety, believing that this is exactly the period for which the fruits fully ripen. This is a common misconception - such a result can be achieved in 2.5 weeks, but only if ideal conditions for growth and development are created - suitable weather, optimal soil and excellent care conditions.
That is why ripening is usually delayed for several days, however, it is not worth overdoing the fruits in the hope that they can still grow a little - a long stay in the soil makes the radish rough, fibrous, with a lot of voids.
How to choose and prepare seeds?
In order to get a good harvest, you first need to purchase good viable seeds, it is advisable to contact specialized stores for this.
After that, the seed material should be calibrated and sorted - seeds larger than 3 cm have the best germination without any external defects - cracks, darkening and dents.
The viability of seeds can be checked in a fairly simple way: the material should be lowered into a strong saline solution for a couple of minutes, stirring with a wooden stick. Those seeds that float should be thrown out immediately - they have no life and it will not work to get sprouts.
Those seeds that remain at the bottom should be washed under cool running water and dried naturally (drying near heating appliances is unacceptable).
Selected seeds should be disinfected shortly before planting, which will prevent the possible occurrence of fungal and bacterial infections of the plant.
Most often, they resort to disinfection in a weak solution of potassium permanganate - for this, the seeds are placed in a gauze bag and dipped into the composition for 15-20 minutes, after which the material is washed and dried again.
In addition, plants respond well to growth stimulation. Experts recommend soaking future seedlings in "Epin" (at the rate of 2-3 g of the drug per 1 liter of water) or in "Zircon" (0.25 ml per 1 liter of water).Seeds are kept for 3-4 hours, then dried and prepared for planting.
If you plan to plant in early spring, then it will be useful to harden the seeds at home - this will increase germination in the event of frost returning. The procedure is quite simple: the planting material is wrapped in gauze or a canvas bag and placed in the refrigerator for 4 hours. After that, it is taken out and aged at room temperature for a day.
This alternation should be repeated many times until the seeds begin to hatch - and after that it is immediately necessary to plant in moistened ground. You should not delay with planting work, since during hardening all growth processes are noticeably activated and in the absence of suitable conditions for growth, the seed simply dies.
Soil preparation
Good soil greatly affects the yield of any garden crop, and radishes are no exception. The plant is quite picky about the composition and structure of the soil, since the fruit ripens in the ground.
To create optimal conditions for the growth and development of radishes, you should prepare the site for planting in advance. The best crop precursors are tomatoes, potatoes, onions and garlic.
In autumn, the necessary fertilizers should be applied to the ground (the amount is indicated per 1 sq. M. Plot):
- rotted manure / compost -10 kg;
- superphosphate - 20 g;
- potassium sulfate - 15-25 g;
- ammonium nitrate - 20 g.
In the spring, you can additionally fertilize the soil with urea, but it is not recommended to introduce fresh manure before planting - it can attract pests that can destroy the entire crop.
Particular attention should be paid to the removal of weeds - weeding should be deep, otherwise the roots remaining in the ground will interfere with the formation of large and dense fruits.
Radishes prefer loose soil, so peat and river sand should be mixed into dense soil during autumn plowing.
In the spring, the digging is repeated and the beds begin to be prepared - they make small grooves 1-1.5 cm deep, the bottom must be compacted with hands so that the seeds do not go deeper when watering or under the influence of precipitation. Row spacing should be approximately 10 cm.
Landing technology and timing
It is noteworthy that radishes can be sown at any time of the year and even in winter. Although in fairness, we note that it rises only after the air temperature rises to 7-8 degrees Celsius and above.
In the spring, radishes are planted at a time when the air temperature during the daytime does not fall below 10 degrees. It is optimal if it is 14-16 degrees - in this case, you can wait for the first shoots already 7 days after planting. And if the weather is warm and the air warms up to 20 degrees or more, then the sprouts appear after 3 days. Under these conditions, the vegetable reaches maturity after 21 days.
However, if the temperature drops, there will be no trouble, young shoots retain their vitality and ability to develop even with frost on the soil, but ripening in this case will occur a little later.
This ability of the root crop allows you to plant it at any time - and this is the difference between the culture and the agricultural technology of all other vegetables.
Another feature of the optimal period for planting in the spring is the parameter of soil moisture.As a rule, after the snow melts, the soil is saturated with moisture, which is a strong stimulant for seed germination, so after the onset of heat, you should not wait for the earthen clod to dry out.
Spring planting radish has a great advantage over planting at any other time - the absence of pests. After all, the earlier the root crop is planted, the lower the likelihood of encountering a cruciferous flea, the tiny worms of which bite into ripening fruits, which significantly worsens their appearance and taste characteristics.
Most often, in the Moscow region and the Central part of our country, heat comes at the end of March - it is at this moment that the sowing season can be opened. Many summer residents plant plants every 10 days in order to receive a continuous harvest throughout the season.
In the Leningrad region, the beginning of sowing falls on the second decade of April, and in the Siberian regions and the Urals, it is better to postpone planting radishes in open ground until June.
In the Kuban, Stavropol, Rostov region, Crimea, as well as in Ukraine and Belarus, sowing is carried out from mid-May, since in these southern latitudes the soil warms up much earlier.
In summer, the planting season can continue at full speed. Just like in spring, seeds can be planted every 10-14 days in the so-called conveyor way. In the hot season, planting work is best done in the morning or evening. In addition, from 19 pm to 7 am, the bed will have to be covered with dark fiber or boxes to protect it from sunlight. In August, daylight hours are significantly shortened, so there is no need for shelter.
Planting work can be continued in September, and starting from October, sowing should be stopped, even if the weather is warm and sunny.During this period, there is a high probability of a sharp drop in temperature, so radishes most often do not have time to ripen before the onset of cold snaps. However, this is the best time to prepare the beds and soil for the formation of winter holes. By the way, November is considered the most suitable period for winter planting, at which time the ground freezes by 5 cm or more, otherwise the seeds may germinate and the frosts that come will simply destroy the plant.
Seeds planted before winter sprout 2-3 weeks earlier than spring ones - and this is a definite plus, since fresh vitamins at a time when young greens are just starting to sprout are very much appreciated.
Over time, landing sorted out. Now let's take a closer look at agricultural technology. The earth should be dug up and harrowed with a rake, and then the most interesting thing is landing.
Seeds are deepened into the ground in several ways.
- The most common option is to lay the seeds in bulk. Of course, this is the most labor-intensive method, but at the same time the most uneconomical - radish seeds are distinguished by high germination. Even the oldest materials tend to sprout at 99%, so when sprouts appear, you need to plant them - a pick will be required, which has its own risks. Firstly, when pulling out excess sprouts, the roots of those plants that remain in the ground can be damaged, in which case they stop developing. Secondly, if thinning is delayed even for 3-4 days, then the rest of the shoots will grow instead of directing their vitality to the formation of fruits.
- Some gardeners prefer to grow radishes in seedlings. - the seedling is prepared at home on the windowsill or on the balcony.Of course, in this case, you can avoid unnecessary hassle with picking and transplanting, but keep in mind that radishes are early ripening vegetables. It takes about 3-4 weeks from the appearance of the first shoots to the full ripeness of the root crops, if you spend this short time uprooting young shoots and planting them in another place, then the plant simply will not have time to gain the necessary mass and juiciness.
A much more accurate landing method would be the following:
- form a bed with grooves;
- fill the ground with water;
- spread the seeds at a distance of 3-4 cm relative to each other;
- sprinkle with dry soil;
- press with your hand.
It is not recommended to sprinkle the seeds with moist soil, since in this case a dense crust forms on the surface, and it is impossible to loosen the soil in which the root crops are germinated in order to avoid damage to the underground part of the vegetable crop.
If the planting is done correctly, that after 4-7 days shoots will appear.
Many experienced gardeners make their work much easier by using ribbons for planting - they are simply laid out along with the seeds laid out on them along the bottom of the beds and sprinkled on top with wet and then dry earth. Instead of ribbons, you can use toilet paper, in which, with the help of a regular paste and wooden toothpicks, seeds are attached with the desired pitch.
A much more convenient way is to use egg containers. With this approach, the seedlings are placed at the right distance from each other, the fruits are even, neat, and, importantly, thinning of the plantings is not even required.
Let's analyze in detail the sequence of actions.
- To begin with, they prepare a garden bed in the usual way: they dig it up and loosen it.
- The bottom of the cardboard cells is cut off and laid on the ground with holes down, and then pressed a little. The cells are filled with water, and after it is absorbed, a seed is placed in each well. Next, the planting material is covered with earth and moistened abundantly.
With this approach to planting, the seeds germinate with standard activity, however, the planting pattern will be followed automatically.
What can be planted next to a radish?
Every gardener knows well that for the successful growth and development of plants it is very important to observe the principles of a good neighborhood. As for the radish, it is best grown with various varieties of lettuce - these crops protect it from the adverse effects of the earthen flea. It will be right to plant radishes next to legumes and nasturtium, which can significantly improve its taste.
Keep in mind that radishes don't like direct sunlight, so it's a good idea to shade them with tall plants. That is why the culture is often sown near tomatoes, parsley, onions, chard and garlic. Not bad radish is adjacent to strawberries, but radishes are not sown next to hyssop.
Care
Growing radishes does not require any special efforts, but, nevertheless, there are rules and recommendations that should be followed.
After sowing the seeds, the earth must be watered daily until the moment when the first shoots appear. The moisture level in the soil should be at the level of 80%, so not only seedlings, but also adult plants need moisture - if there is not enough water, the fruits will be bitter.
At the same time, it is important to avoid stagnation of liquid, since in the marshy ground there is a high probability of being affected by ailments such as keel or blackleg.Irrigation should be as uniform as possible, with any sharp change in the irrigation scheme, the roots immediately crack.
Planting should be moistened twice a day - early in the morning and in the evening, when the heat subsides. In order to maintain the required level of humidity, especially in summer, the ground on the site can be mulched with sawdust or hay.
Growing root crops need fertilizer. The plant responds well to both mineral compositions and organics. Manure has a very good effect on radishes, but just rotted - fresh to the plant is contraindicated. From it, the culture begins to shoot and the fruits grow empty inside.
Fertilizers are applied in liquid form. After each, the ground should be mulched with peat - this will make the soil more airy, and the root crops will turn out crisp and juicy, without coarse fibers and voids.
If you properly care for the plant, you can grow a good harvest of tasty and appetizing fruits.
Diseases and pests
Radishes are quite often infected with diseases and are attacked by garden pests that can destroy the entire crop. Given that the ripening of the fruit occurs quite quickly, every day of the disease can become "fatal" - radish treatment should be started immediately when the first signs appear.
Radishes have some of the most common offenders.
quila
Signs of such a disease are the appearance of growths and swellings on the surface of the root crop, as a result of which the fruit acquires a yellow color and a wilted structure.
The diseased plant should be dug up and burned, and the ground in which it grew should be sprinkled with slaked lime. This site can be used for radishes no earlier than 4 years later.
powdery mildew
A lesion in which a white coating appears on the ground part of the plant, over time it becomes light brown.
It is quite difficult to treat powdery mildew, so it is best to pay special attention to preventive measures - for this it is necessary to observe crop rotation and treat the seeds with fungicidal compounds before sowing.
bacteriosis
A dangerous disease, a symptom of which is the appearance of mucus on the fruits, which begin to emit a sharp putrefactive odor. All this is accompanied by a sharp yellowing of the leaf plates. In this case, you can correct the situation by using Bordeaux liquid.
No less harm to the plant is caused by garden pests. It is worth noting several pests that most often attack plants.
cruciferous flea
This small insect is dark in color with a characteristic metallic tint. It causes damage to the leaves, thereby disrupting photosynthesis and ultimately leading to the death of the entire plant.
Insecticides are used to control the fly.
Belyanka
Radishes are harmed by larvae that eat the tops along the edges or gnaw through holes in the leaves. In any specialized store, you can find chemical and biological agents that successfully fight the whitefish.
Harvest and storage
Root crops are harvested as the radish ripens. The fruits are pulled out on a selective basis, for this you just need to grab the tops and pull up. First of all, those whose leaves have reached the maximum size for the planted variety are harvested, and the smaller ones are left to ripen.However, if for some reason growth stops, then it makes sense to pull out the fruits in the state in which they are - they will not become larger, and too long a delay in the ground will lead to a significant deterioration in the structure of the fruits and their taste.
The harvested crop can be eaten immediately or put in the refrigerator, where it can be stored for two weeks.
Late varieties can be kept in the cellar - under these conditions they retain their appearance and taste for up to two months.
