Weeds in the lawn
weeds are any species not included in the initial mixtures.They can be both annual and perennial grass seedlings woody plants and even grains, which differ from their counterparts lawn appearance.We loved the lawn they get in three ways - from a stock of seeds in the soil, drift various natural agents (wind, melt water, birds, etc.) and present as an impurity in poorly treated seeds of lawn grasses.
Particularly impressive soil seed bank: in the upper layer of soil over an area of one square decimeter number of viable seeds can be hundreds or thousands.They give outbreaks of weeds on the young, just sown the lawn.It occurs in the first weeks after the planting.The vast majority of weeds presented annual and biennial plants, such as white pigweed (quinoa), shepherd's purse, Thlaspi arvense, chickweed (chickweed), daisy and many other species that are familiar to us vegetable garden beds.Shoots annuals are developing vigorously and often grow faster than seedlings sown cereals,
Especially a lot of trouble gives the appearance of a lawn perennial weeds.They are well known to the reader its presence in the running and shoddy lawns where these species cover their leaves more than half of the area.This dandelion, bloodroot goose, plantain, cuff, yarrow, clover white, knot-grass, hairy hawkweed, Ranunculus repens, schavelek, common groundsel, and others. All of these plants have short stature and have the ability or form rosettes of leaves, or start creepingrooting shoots, or create a dense network of thin shoots squat.Some of them even stalks low altitude.
All this helps to avoid the perennial weeds mower blades, and the other delights lawn life (lots of light, watering, soil is fertile, mineral supplements) they are satisfied.They spoil the look of the lawn, its homogeneity, many of them are able to fully compete with cereals in the consumption of environmental resources.The number of perennial weeds and their aggressiveness increase with worsening living conditions sown cereals, but with proper care it still manages to infiltrate the herbage.So without weeding is indispensable even in mature and high-quality lawns.
weeds fight hard.But it should be understood that the war with dandelions on lawns adults - is, in most cases, the elimination of the consequences of improper care or too large recreational load.Therefore, the most effective tool against the invasion of weeds has been and remains a regular lawn care.It is to create optimal conditions for the growth of sown crops, which in normal development are unlikely to be allowed on the lawn uninvited guests, whether higher plants, mosses or fungal infections.
Weed control really is a struggle, sometimes exhausting and long.The most effective method - Digging perennials using a narrow shovel, knife or sharp-edged steel strips.When you remove the weed should be possible to trim its deeper roots.But the cumbersome mechanical removal, especially on lawns running.In this case, apply the herbicides that reduce labor costs 80-90%
can use herbicides continuous action and selective herbicides.The first group includes drugs Amitrol-T and Roundup.When working on the lawn of a dot is applied to the leaves of weeds with a cotton swab (concentrated solution in water at a ratio of 1:10).
most effective results provide lawn selective herbicides.Usually these substances destroy dicotyledonous plants without damaging monocots, i.e.seeded cereals.They sprayed the surface with a garden sprayer.Such drugs began to appear on the shelves of our stores.Their names may change, so should pay attention to the active substance, which is always specified in the instructions for use.
working with herbicides, especially to remember their high toxicity.Basically, this is a very dangerous substance, so it is necessary to strictly observe the rules of use, which necessarily attached to it.Commonly used all personal protective equipment - goggles, dust mask, rubber gloves, rubber boots.Clothing gardener should be made of thick fabric.You should also bear in mind the harm that can be caused to the environment: inadmissible dripping herbicide on plants other plantings (trees, shrubs, flowers, vegetables, etc.), preparation impermissible contact with pets.Many specialized herbicides can accumulate in the soil.It is clear that the use of these substances - a last resort, when all other means of weed control are not helping.
Care youngest seeded lawn
Lawn created the sowing of perennial grasses, is designed for continuous operation.For the period of its use without reseeding it was tens (or maybe hundreds) of years and kind of green carpet all the time feast for the eyes, requires regular care.The idea is simple - easy in the garden did not grow.But, sometimes, faced with the opinion that more important than the right to plant a lawn, and evolve to become thicker and greener than it will by itself, you just have time to cut it, well, maybe sometimes watered for their own pleasure.
Of course, it is not.Favorite emerald lawn requires a strict and constant care regime, without which it will turn over time of an ordinary lawn luxury wasteland, overgrown with nettles and goutweed, or hard-packed ground with stunted remains of once sown grass.And he and the other option evolution lawns can be successfully observed not only in the practice of urban gardening, but even in many suburban areas.
Care youngest seeded lawn is weed control, mowing gently and use, as well as regular monitoring of mineral nutrition and soil moisture.
first thing to face the newly sown lawn - a growing abundance of annual weeds.But it should not be afraid - these plants can not tolerate frequent mowing, moreover, they reproduce only by seeds.Therefore, the most effective measure to combat annuals is mowing their shoots sharpened hand-scythe.This high shear prevents flowering and colonization of annual weeds and practically does not injure the seedlings of cereals.To bring down the "wave" of annuals is usually sufficient to hold one or two before the first mowing of the hay crop.Particularly tenacious weed specimens removed later digging.For those who are not afraid to use on your site chemicals, we can recommend the use of selective herbicides, destroying annuals, but not damaging seeded cereals.
In the first weeks of life of the lawn to move on it at work, it is desirable to use a wide boards or plywood panels.They significantly reduce the burden on the fledgling herbage, and after removing the planks trampled grass rises after the first irrigation.During the first season, walking and relaxing on the lawn exclude - on the formation of turf seeded grass takes an average of one year.
first young sheared carpet when the herbage height of 10-15 cm. The cut is carried out with the help of the mower at the height of 4-5 cm. Particular attention should be paid to the sharpness of knives - they need to be razor sharp.Otherwise the plants will be pulled out of fragile sod.Subsequent mowings carried out when the grass height of 7-10 cm, the last mowing of the season do in mid-September.We must not forget the mandatory removal of mown grass residues.
If the soil matrix is made with high quality and the root layer of soil has enough potential fertility, the grass on the new mineral fertilizing is carried out in a half-dose of the one that is recommended for mature grass.Otherwise, on marginal soils, fertilizing perform the full scheme.The calculation and timing of fertilizer application are listed below, in the section on long-term care of the main lawn.
main lawn care formed
All activities for the care of long grass can be divided into compulsory, optional and specific.The former include the control of weeds, mowing, fertilizing, watering and cleaning the surface.The second group includes mulching, soil aeration and packing.Special care is to counter the penetration on the lawn of moss, insects, nematodes, fungi and animals zemleroyuschih.
golden rule of every self-respecting gazonovoda formulated as follows: "mowed, and fed, watered."The lawn can not exist without cutting.But with cut leaves and stems from the ecosystem removed a significant portion of mineral elements, without which the seeded cereals will not be able to quickly restore the grassland.For this we have to feed after each mowing the lawn fertilizers.And in order to dressing came to the roots of crops as soon as possible and has been used most effectively, it requires watering.Strict adherence to this process chain creates optimum conditions for classical lawn grasses and green cover makes beautiful, functional and durable.This is one of the simple secrets of centenarians English lawns.
mowing.Mowing lawns formed (in the second and subsequent years of life) begins in the spring when the grass height of 8-10 cm;subsequent mowings are at intervals of one to two weeks when the herbage height of 5-8 cm;the last mowing is carried out in late September or early October.In this climate it is not recommended to do mowing more than 25 times during the growing season - too intense shearing leads to a weakening of lawn grasses.When selecting the cutting height, you should not rely on European standards - we have it is 2.5-3.0 cm (incidentally, the same height adhere Canadians).In the autumn lawn shear at a higher cut - 4-5 cm.
Mowing the lawn mower traffic conducted by the "snake" of alternating strips of lawn edges bypassed again after mowed main square.One good rule is to change the direction of cutting clippers.If the mower from mowing hay crop to go the same route, the blades of grass become a constant slope and stiffen.On the lawn there is a steady striped pattern, and the grass becomes withered shade.
every three to four mowings check the sharpness of the mower blades and, if necessary, make their grinding and finishing.The first sign of a lack of sharpness of the cutting edges - ragged, yellowing and drying soil the tips of the leaves and cut stems that on the lawn look like a nasty whitish "bloom."
not beveled pieces of grass, which remain on the lawn in remote places, cut with special scissors or trimmers and line.Aesthetes grass businesses can purchase for this purpose small rechargeable trimmers, something resembling hair clippers.
Cleaning mown residues that rotary mowers in abundance on the surface of leaves, taking care is a must.The presence of lumps and lumps of grass spoils the appearance of the lawn reduces water permeability and aeration of the top layer of soil contributes to the creation of favorable conditions for various diseases putrid herbs.What remains of feathered "feed" lawn - the old, but, unfortunately, a persistent error.By the way, the compost produced at the disposal of grass in a special box, has a very high quality and speed of maturation.
feeding. Key elements of mineral nutrition of lawn grass - it is the so-called macronutrients: nitrogen, phosphorus and potassium.Their arrival on the lawn to compensate for losses from the mowing should be necessarily complex.It can not be excluded from the diet at least one of these elements.At the same time, they must be done in a fairly strict ratio for optimum nutrition of lawn grasses (nitrogen: phosphorous: potassium = 1: 2: 1 or 2: 2: 1).The imbalance in the mineral nutrition usually leads to the growth of dicotyledonous herbaceous plants that are weeds on the lawn.
Meals are made after every mowing (not necessarily on the same day, but it is not necessary to delay for a long time).Conveniently advance, even in winter, to make fertilizer sample for each mowing: we calculated annual dose multiplied by the number of square meters of lawn and divide it by the number of mowing (their average is 12 to 15).Sample of each type of feeding rasfasuem in paper or plastic bags and place on the shelf - all as a pharmacy, accurately and clearly.Packages can even sign, indicating the number of mowings and type of fertilizer.At the same time we take into account three things: 1) Different types of fertilizers should be stored in different packages (they can only be mixed before entering), 2) a first spring fertilizing is done immediately after the growth of new grass, 3) on autumn fertilization plan making only phosphorus and potassium products(in September and October of nitrogen do not contribute, not to stimulate the growth of grass in late autumn and in the snow).
After mowing grass and removing residues in a plastic bucket to pour the prepared dose of fertilizing, then, wearing rubber gloves, mix fertilizer and scatters them evenly over the entire area of the lawn (but not necessarily with the same care as we once sowed grass seed).Now you can go to the most pleasant of our operations in the processing chain, to watering.
watering. water to dissolve the crystals and lawn fertilizer granule, and delivers them to the suction grass roots.The amount of water required for irrigation, depends on the weather, soil permeability, density, ground cover and sod.In any case, it should be so abundant water to nourish the soil root zone (15-20 cm).The average of the lawn formed by the water flow rate is 10 to 20 liters per square meter.
course, lawn watering is required not only when mowing.If there was no rain for a long time, drooping leaves, blades of grass sluggish signal that it is time to water the lawn.But in the dry and hot weather this should be done only in the morning and evening, so as not to expose the lawn grasses temperature stress.
Cleaning lawn. addition to the mandatory removal of cut grass is required to monitor the state of the surface of the lawn and grass cover.In the spring, after the snow melts, you need two to three times matted grass comb fan-rake to remove dead of winter leaves and stems.In the fall from the surface regularly remove fallen leaves.This not only eliminates the shadowing turf grasses, but also prevents their damping-off under the snow.The edges of the lawn during the crop growing season and trimmed, avoiding superimposing the turf and flower beds on the track.
Calculation of doses of fertilizers
lawn ecosystem losses resulting from the removal of macronutrients mowings on an annualized basis is an impressive value.It is believed that one needs m2 herbage in introducing the fertilizer to an average of 24 g of nitrogen, 36 g of phosphorus and 24 g of potassium hydroxide.
for dressings can be, and sometimes more convenient to use traditional domestic formulations, it is only important to correctly calculate their number.Here's a list of the best-known mineral fertilizers produced in our country:
- simple fertilizer - ammonium nitrate (34.5% nitrogen by active substance), urea (46% nitrogen), sodium nitrate (16.0% N), simple superphosphate(20.5% P), triple superphosphate (50% P), potassium chloride (60% potassium), 40% th potassium salt (40% potassium);
- complex fertilizers - potassium nitrate (containing 13.5% nitrogen and 46.5% of potassium), ammonium phosphate (12% nitrogen, 50% phosphorus), NPK (17% nitrogen, 17% phosphorus, 17% potassium), nitrophoska(12% nitrogen, 12% phosphorous and 12% potassium).
start to count.If the ammonium nitrate contains 34.5% nitrogen by active ingredient in granular double superphosphate is 50% of the phosphorus and the potassium chloride comprises up to 60% of potassium in a year per 1 m2 of lawn we should add about 70 g (more precisely 24 gx 100: 34.5 = 69.6 g) of ammonium nitrate, 70 g (36 g of 100: 50 = 72 g) and 60 g of superphosphate (24 g of 100: 40 = 60 g), potassium salts (in the amount of about 200
