What types of lawn fertilizers are there and when to use them

Lawn fertilizers cannot be divided only into "strong" and "weak". They differ in their purpose. Some are needed at the start, when the lawn is just being created. Others work in spring to recover after winter. Still others support the grass in summer, when it experiences heat and stress. Autumn formulas are used separately to prepare the lawn for the winter period. If you confuse these tasks, the fertilizer may not give the desired effect.

Starter pre-sowing fertilizers are applied before sowing or during lawn seeding. Their main role is to help seeds germinate quickly, form a strong root system and evenly cover the area. In such formulas, phosphorus is important because it is associated with root development. For a new lawn, this is the basis of future density. If the root system is weak at the start, the lawn may germinate unevenly, tolerate the first mowings worse and close empty spots more slowly.

At Progreen, pre-sowing fertilizer Greenbion Prime mini 10-20-5+TE+AA can be used for starter application. Its logic is simple - to give young grass enough nutrition for rooting and uniform development. Such fertilizer is appropriate when creating a new lawn, overseeding damaged areas or renewing the grass stand. For pre-sowing application, it is important not only to choose the right product, but also to distribute it evenly over the area so that young seedlings get the same conditions.

Spring lawn fertilizers have a different task. After winter, the grass often comes out weakened. Some of the leaves may be yellowed, the root system works slower, and the lawn surface needs to recover from cold, snow, moisture or temperature changes. During this period, the lawn needs nitrogen, which triggers active growth of green mass and helps restore color. Spring feeding actually sets the pace for the entire season, so it should not be skipped.

Summer lawn fertilizers should work more carefully. In summer, the grass is often under stress due to high temperatures, lack of moisture, active use of the area, children's games, walking, furniture on the lawn or sports loads. During this period, it is not always necessary to sharply stimulate growth. It is much more important to maintain density, color and stability. Summer feeding should help the grass withstand difficult conditions without overload.

Autumn lawn fertilizers are needed to prepare for winter. Here, excess nitrogen is already undesirable, because it can stimulate active growth, which is not needed before cold weather. The main emphasis shifts to potassium and phosphorus. Potassium strengthens cell walls, increases plant endurance, helps grass better tolerate low temperatures and weather changes. Phosphorus supports the root system. Autumn feeding does not always give such a bright quick visual effect as spring feeding, but it greatly affects how the lawn overwinters and in what condition it starts in spring.

That is why there is no one universal lawn fertilizer for the whole year. Grass has different needs depending on the season. If spring requires an active start, summer requires stability and resistance, and autumn requires preparation for cold weather, then the formulas must be different. Attempting to use the same composition throughout the year often ends up with either a weak effect or overloading the lawn in the wrong period.
