If your lawn needs to be scarified, you can easily see it: pull a small metal rake or a cultivator loosely through the turf and see if old Moravolster and moss pad stuck to the tines. A strong weed growth is also a clear indication that the turf grasses are inhibited in growth. Either the lack of nutrients or just a thick layer of lawn felt hampers the oxygen supply to the turf roots. Grassy fissures are susceptible to heavy, airless, loamy soils that are prone to waterlogging, as well as shady lawns. For optimum decomposition of the residues, however, a well-ventilated soil, heat and a uniform water supply are important.
The right scarifier
Scarers have a horizontal built-in spindle or axis, which is occupied at short intervals with rigid or rotatably mounted knives. The motor rotates the axle, while the blades scratch the turf a few millimeters and knock out moss and turf felt.
Petrol scarifiers are the first choice for scarifying larger lawns. You also have the advantage that you do not have to pay attention to the power cable. As a rule, contact with the sharp knives is not unscathed. In addition, petrol scarifiers provide the necessary weight, especially on heavy, dry soils, to allow the knives to cut sufficiently deep into the turf.

Electric scarifiers are completely sufficient for smaller, easily accessible areas. Since the equipment is usually used at most twice a year, you can easily overlook the fact that the handling is somewhat cumbersome because of the stoma cable compared to the lawnmower. Very light electric scarifiers tend to "hitch" on hard soils because the knives can not penetrate into the turf. tip: In such a case, simply complain the device with a small sandbag.
Hand Verticutters have rigid or slightly pendulum-mounted knives. They require a lot of effort and are only suitable for small lawns or for treating individual matted areas.
With a hand scarifier you can manually clear small lawns from the felt
Scarify the lawn: time and preparation
Basically, you can scarify your lawn with proper care from April to September. However, if you use the lawn intensively in the summer months, you should take care of it in spring or late summer, because the green carpet then needs a few weeks of protection to be able to regenerate. The care program for the start of the season starts with spring fertilization. In the garden one can orient oneself well on the narcissus blossom. As soon as the onion flowers are in full bloom, the grass will grow again and be able to utilize the nutrients supplied. Then the green carpet is once mowed to normal height (about four centimeters).
As soon as the second lawn mowing is pending, ie about two weeks after fertilization, the right time has come to scarify. The grasses are now optimally supplied with nutrients, so that the traces of scarifying disappear within a few weeks. The experiences of the past years have shown that one should not wait too long to scarify. The May was often very warm and dry, so that then an additional irrigation was necessary so that the sward could close quickly.

This is how you scarify properly
1. Just scarify dry lawns.
2. Set the scar level correctly. The knives are allowed to scrape the turf a maximum of two to three millimeters deep.
3. Before mowing, cut the lawn to two centimeters (lowest setting of the lawn mower).
4. Guide the device quickly over the surface and do not stand too long in one place, otherwise the turf will be damaged too much.
5. First, move the device across the surface in longitudinal and then in transverse paths to create a fine checkerboard pattern.
6. When changing direction, push down on the guide rail so that the blades are in the air.
7. Seed bald spots immediately after scarifying with fresh lawn seeds.
8. Rake off the loosened lawnfelt thoroughly from the lawn.
9. Sprinkle lawns on heavy soils after scarifying with a layer of building sand about two centimeters thick to improve the soil's air balance.
