Let’s see, we know the climate and the type of soil of our land, in principle of earth development we would have everything to go on to choose the variety of grass that interests us the most.
There is only one last question, to analyze if our lawn will be in a covered area (by the shade of trees) or full sun, since depending on what type of lawn is better or worse adapted to this issue.
What Use Will You Give?
With this question, we mean the following. Does it only have an aesthetic function? Are children going to play in it? Depending on this, you will have to choose an essential condition, a type of grass that is more resistant, thicker, and with greater recovery capacity.
The Phleum pratense variety is creeping and is often used in sports fields because it recovers well.
The Lolium species are thick-leaved and ephemeral, but they are cheap and grow relatively quickly.
The grass of the genus Poa has horizontal rhizomes that form a vigorous lawn.
Agrostis species grow upright and outward, but with separation between leaves. Controlling watering, fertilizing, and cutting the lawn stimulates the density of the lawn.
The genus Festuca forms an elastic lawn (it recovers well) but has the disadvantage that it does not spread quickly.
Scarification And Aeration
Aeration and scarification are operations whose purpose is to avoid caking or compaction of the same and avoid mosses’ growth, for example. To aerate it, simply pierce the lawn regularly with a pitchfork in two perpendicular passes.
Scarification also makes it possible to lift what is called felt.
Felt is a compendium of flattened grass, roots, and caked earth that is becoming increasingly waterproof. Scratching with the pitchfork, we will lift the felt, and we will also take away a few shallow-rooted weeds.
When To Aerate Natural Grass?
The best time is when spring has entered in all its splendor, in April. The grass begins to grow vertiginously, and it is when it demands more good conditions of humidity and aeration in the soil.
If you have some practically unrecoverable areas, you can also opt for replanting or repopulating plantings.
Fertilization Of Natural Grass
Fertilization is another important point, which depending on the type of lawn, will need more or less. Fertilization helps the lawn grow more vital and more vigorous, preventing or at least hindering some weeds’ growth.
Others will grow as strong or more than the grass itself, but this is what we are here for, to eliminate them. The base of this fertilization must be nitrogen, although balanced fertilization in nutrients does not hurt.
In the market, you can find many different types of fertilizers especially suitable for natural grass.
One of the most common ways to fertilize is with granules with an NPK 3-1-2 ratio. For example, a 20-5-10 must have calcium, magnesium, and micronutrients (especially iron).
The dose to apply this type of fertilizers is between 30 and 35 grams per square meter of surface. It is essential to moisten the fertilizer with a watering later so that it is released slowly.
If the area in which we have natural grass planted usually has irrigation water with a lot of salts (hard water), it is better to always look for those nutrients that do not have chlorine in their composition.
