Features of mulching cucumbers in open ground
Many gardeners ask topical questions whether to mulch cucumbers, what is the use of it, how laborious and costly this work is. Let's take a closer look at this technology.
Characteristics of the procedure
To grow strong and healthy cucumbers on your site, you need to take care of good watering, the absence of pests / pathogenic bacteria in the root system of plants, and also protect them from night temperature drops. A very simple technique will help to cope with this difficult task - mulching. Today we will get acquainted with the features of this process.
Mulching is the covering of the top layer of soil in the beds with materials of natural and artificial origin.
The procedure itself is very simple. Mulch is applied to previously fertilized and loosened soil, completely covers it, protecting it from the effects of an aggressive external environment.
This allows:
- keep moisture in the ground;
- prevent soil erosion processes;
- develop a strong root system of the plant;
- preserve useful substances accumulated in the soil;
- avoid the growth of weeds, as well as reduce the number of weeding several times;
- protect seedlings from rodents and insect pests;
- get a richer and earlier harvest.
Some summer residents do not see much point in using this agricultural technology.In fact, such work should not be neglected. This method was suggested to people by nature itself.
In a hot summer in the forest it is difficult to find young plants dying of thirst or tortured by pests. The earth, covered with fallen leaves, needles, branches and pieces of bark, is reliably protected from the scorching sun, as well as the evaporation of precious moisture - it is difficult to reach the roots of plants and dangerous pests.
Mulching is an easy way to protect the soil and take care of vegetable, berry, and flower crops. It helps gardeners increase productivity, saves their time and energy. This procedure should be carried out by those who grow cucumbers in the open field. This is especially beneficial for urban residents who do not have the opportunity to come to their site every day to loosen, process weed beds, and also water them abundantly.
Cucumbers love water, so many summer residents install automatic or drip irrigation in their plots, hoping that it will replace their temporary absence. But, unfortunately, this is not always effective. Water can simply nail the dust on the ground, but not penetrate to the drying roots. Mulching will solve this problem. It is useful to carry out such an operation in greenhouses made of polyethylene and polycarbonate.
Pros and cons
The mulching method has a lot of advantages:
- the earth does not crack during a long summer drought;
- there is no crust on the surface after watering;
- free access of air to the root system;
- preservation of nutrients in the soil obtained during top dressing;
- obtaining additional nutrition during the formation of humus during the decomposition of organic mulch;
- soil temperature stabilization;
- lowering the overall level of humidity in greenhouses;
- mulching is carried out 1 time per summer, then it is only supplemented with fresh material;
- cucumbers will be clean - dirt and dust will not rise from the ground to the fruits;
If we talk about the shortcomings of agricultural technology, then they are much less.
- It is not recommended to make a layer of mulch more than 2 cm if clay soils are used (more viscous and heavy). Organic mulch will begin to rot, contributing to plant disease. This also applies to gardens located in the vicinity of groundwater.
- It is dangerous to use freshly cut grass as mulch. It makes it difficult for fresh air to reach the roots, which is especially important for cucumbers. Attracts worms and slugs that can harm plants.
- Dry wild herbs for mulch can also be of dubious use, as they may contain seeds that can germinate quickly and then interfere with the free growth of lashes.
- Organic grass mulch, starting to rot quickly, creates an excellent habitat for various beetles and larvae, for which birds flock to the beds. It is possible that feathered hunters will eat not only worms, but also your cucumbers.
- Field mice and hamsters can settle in straw / grass in the garden.
- With inorganic mulching, materials such as film, expanded clay, gravel make it difficult to apply fertilizers, as well as carry out cleaning work on the site.
When should you do it?
With the arrival of the long-awaited heat, it is time to plant cucumbers, as well as carry out mulching.
Cucumbers love warmth, as well as soil well warmed by the sun. If cold snaps are not expected, the air temperature reaches up to 25 degrees during the day, and does not drop below 16 degrees during the night, vegetable seedlings are planted in open ground and mulched.In the regions of our country, favorable conditions for planting / mulching procedures occur at different times. It depends on the climatic conditions.
- In areas with a warm climate, the best time to mulch is mid-May.
- The first days of June are the time for mulching in the Middle and Middle Black Earth regions of Russia
- The first decade of June - in all regions of the country.
When planting seeds in open ground, mulch the soil when the first 3 true leaves appear. Cucumbers are sown directly into the ground 2-3 weeks earlier than seedlings are planted, so the timing of mulching cucumber seedlings, as well as mulching seedlings, practically coincides.
In polycarbonate greenhouses at a temperature of +20 degrees, the procedure is carried out earlier.
- Warm regions - the last decade of April.
- In the center of Russia - the middle of May, or the first days of June.
- Siberia, the Urals, the Volga region - the last days of May.
When planning to do mulching, rely not only on general information about the timing of the procedure, but also act according to the circumstances. Watch the weather, air temperature. Check the soil (watch how warm and wet it is).
Ways
In the open field
Before planting seedlings and mulching the soil, all weeds are pre-weeded.
- Mulch is applied around cucumbers and between rows.
- Do not put mulch under the stems - this can damage the lashes and cause various diseases.
- The bottom layer quickly rots, so it is necessary to replace the organic mulch / supplement it with fresh for the entire period of growth and maturation of the culture.
- When mulching cucumbers in any inorganic way, you must first apply a dry top dressing for plants of prolonged action.
- You can water with the addition of liquid fertilizers all season directly from the watering can on top of the mulch.
In closed ground
Mulching cucumbers in the greenhouse is carried out in the same way as outdoors - when it becomes warm, and the soil is completely warmed up.
- The earth on the beds is carefully leveled, wide aisles are made.
- Bring the selected mulch to the surface,
- The layer in the greenhouse is desirable no more than 2-5 cm,
- Change the mulch as needed, as soon as the bottom layer rots. To see when this happens, the formation periodically rises in some places. This is how the presence of uninvited residents under the cover is checked - beetles, lizards, snails.
- In artificial mulch, holes are first made for seedlings.
- First, material is laid on the beds, and then plants are planted in the holes made.
- In polycarbonate greenhouses, it is better to use organic mulch, natural burlap, a thin layer of straw or peat mixture
- It is better to refuse the use of a black film that attracts the sun's rays in the heat.
Having become acquainted with the variety of methods and materials, you can easily decide which mulching products are suitable for your site or greenhouse.
- Well-rotted compost.
- Sawdust along with nitrogen fertilizers.
- Decomposed cow dung.
- Husk from seeds, pine nuts.
nettle
Mulching with nettles is one of the easiest and most economical ways. You can find nettles at every summer cottage, so there will be no problems with raw materials. The protective layer of these plants not only fulfills its main task - it saves the beds from moisture loss and temperature changes, but also copes well with other problems.
- Fertilizes the earth.
- Prevents weeds from germinating.
- Does not allow slugs and snails to live in the beds.
- It promotes reproduction under its cover of useful inhabitants, loosening the soil, forming humus.
- Fights the appearance of dangerous aphids on cucumbers
Making nettle mulch is easy. Beveled nettles without seeds need to be dried, chopped with a thresher or simply by hand. The finished mulch should be spread out in a layer up to 4 cm on the beds around the plants, without touching the stems.
To prevent the plant from burning, you can mix it with wood ash. It is practiced to add ash prepared from the nettle itself to the mulch. It contains potash, a salt of potassium carbonate. This is an excellent natural plant food that does not contain chlorine.
Nettle is rich in various valuable trace elements and vitamins. It contains iron, nitrogen, necessary for plants. Some gardeners bury it in the beds shortly before planting seedlings of cucumbers, mulching to further enrich the soil.
Among the mass of advantages, this method has only one minus - the nettle quickly overheats in the summer sun. You have to add a new layer of mulch twice, or even three times a month.
During wet weather, a thick layer of nettles may develop gray mold. This happens if the mulch cover is too thick and the plants are chopped too coarse. Such a layer must be removed and not too lazy to put a new, finely chopped mulch.
Straw
Mulching with straw can be used both in open ground and in a greenhouse. Like nettles, it is better to cut the straw into mulch. Before use, nitrogen fertilizers must be applied to the beds.
Straw is the only mulch that is applied to the soil in a thick layer of up to 10 cm, as it is quite airy. Some time after placing on the beds, the layer will sink and become much thinner.
- During the procedure, do not scatter the straw in heaps, large armfuls. Lay it evenly in strands.
- A very thick layer should not be applied - under a large cover, pathogenic bacteria that are harmful to plants can form.
- To avoid problems, straw can be pre-disinfected by soaking in a weak solution of potassium permanganate, and then dried in the sun.
- You can mulch with straw in combination with compost or rotted manure.
- It is advisable to mix the mulch with urea before use in the proportion of 200 g of fertilizer per 10 kg. straw
Any straw is suitable for mulching cucumbers. Collect it in advance at the end of summer (after harvesting cereals). Since mulching of cucumbers will be carried out only next summer, the straw must be prepared for the future.
- Spread the raw material in a thin layer in the sun.
- Dry, periodically turning with a pitchfork.
- Collect the dried mulch in bags, and then store it in a well-ventilated area.
Straw mulch helps:
- maintaining soil fertility, saturating it with vitamins and microelements;
- protection of young plants from overheating and cooling;
- maintaining the required level of soil moisture;
- increase in productivity.
Tips
Consider some useful tips related to the procedure for mulching cucumbers.
- When growing cucumbers in a polycarbonate greenhouse, remember that in hot weather, when it is more than 30 degrees outside, the temperature inside is 2 times higher. Don't forget to open windows and ventilate it.
- To avoid overheating, buy white non-woven fabric at any garden center and then cover your greenhouse with it.
- If you still use black film, cover white material on top of the dark coating in the heat. This will save the cucumbers from overheating.
With any method of mulching, remember that the covering layer of material is not placed close to the very stem of the plant in order to avoid destructive diseases.
