Eisensulfat II: Der perfekte Frühlingsdünger für Ihren Rasen

Spring is finally here, bringing with it the anticipation of a lush green and healthy lawn. However, signs of iron deficiency often appear in spring, making the lawn look pale and sickly. This is where ferrous sulfate II comes into play – the perfect fertilizer to get your lawn back in shape.

What is ferrous sulfate II and how does it work?

Ferrous sulfate II, also known as ferrous sulfate, is an important nutrient for plants. It is a salt containing iron in its divalent form (Fe2+). This iron is essential for many plant life processes, especially for chlorophyll formation. Without sufficient iron, plants cannot properly produce the pigment chlorophyll, leading to deficiencies such as yellowing and leaf deformities.

By applying ferrous sulfate II, this important nutrient is supplied directly to the lawn. The salt dissolves in the soil and is absorbed by the grass roots. In this way, it provides the plants directly with the iron they need, allowing them to grow strong and healthy again.

When and how should ferrous sulfate II be applied?

The ideal time to apply ferrous sulfate II is in spring, when the lawn awakens from winter dormancy and needs a new nutrient boost. The grasses are then particularly receptive to the iron application and can optimally utilize the fertilizer.

It is best to evenly spread the ferrous sulfate II over the entire lawn during dry weather. The granules should then be quickly washed into the soil by rain or worked in so they can be absorbed directly by the roots. An application rate of 30-50 g per square meter is usually sufficient.

It is important not to mix ferrous sulfate II with other fertilizers or lime products. Otherwise, the iron can become insoluble due to chemical reactions and inaccessible to the plants. It is best to leave a few weeks between applying ferrous sulfate II and other fertilizers.

What are the benefits of ferrous sulfate II for the lawn?

Using ferrous sulfate II as a spring fertilizer offers numerous benefits for your lawn:

1. Intense green coloration

Thanks to optimal iron supply, the grasses can fully produce the pigment chlorophyll again. This gives your lawn a deep green, healthy color.

2. Strong growth

With the additional iron, the grasses grow especially lush in spring and form a dense, resilient lawn cushion.

3. Increased resistance

Iron-rich plants are generally more robust against diseases and pests. Your lawn will therefore be less susceptible to fungal infections or insect damage.

4. Long-lasting effect

The iron application unfolds its effect over several weeks. This way, your lawn benefits from the nutrient supply over a longer period.

5. Environmentally friendly

Ferrous sulfate II is a purely mineral fertilizer that contains no chemical additives. It does not burden the soil or groundwater.

How to recognize iron deficiency in the lawn?

Before applying ferrous sulfate II, it is important to check whether your lawn is actually suffering from iron deficiency. There are a few characteristic signs:

  • Pale green or yellow discoloration of the leaves, especially at the tips and edges
  • Reduced growth of the grasses
  • Scrawny, patchy appearance of the lawn
  • Increased susceptibility to diseases and pests

If you observe these symptoms in your lawn, now is the right time to start fertilizing with ferrous sulfate II. This will quickly get your lawn back in shape!

Conclusion: Ferrous sulfate II – the key to a healthy, green lawn

Ferrous sulfate II is an effective and environmentally friendly fertilizer that gives your lawn exactly the iron boost it needs in spring. With its help, you can correct deficiencies and make your lawn shine in full splendor again in no time.

Through the intense green coloration, strong growth, and increased resistance of your grasses, you will soon see the positive effects of ferrous sulfate II fertilization. Try it out and enjoy a healthy, lush lawn all summer long!
