Lawn care and maintenance in Winter

Preparing your lawn for winter with the best 10 inch table saw blade in the best possible way is the key to making sure your lawn arrives beautiful and healthy in spring.

During the winter the lawn is subject to considerable thermal stress and at the same time its vegetative activity slows down due to low temperatures and limited daylight.

Our efforts must therefore mainly focus on helping the strengthening of plant structures and supporting the photosynthesis of chlorophyll.

FERTILIZATION NEVER TO BE FORGOTTEN!

The most important, fundamental and unavoidable work to be done in the turf is to carry out a potassic fertilization using a fertilizer with a high potassium content.

The ideal fertilizer should contain at least 20/25 units of potassium and a fair amount of nitrogen, around 20 units. Nitrogen should be present all in a slow-release formulation.

WHY GIVE POTASSIUM?

Potassium is an element that should never be missing when the turf goes through seasons of thermal stress. Let’s see the main benefits:

  • It increases saddle thickness and mitigates the negative effects of cold weather
  • Extends the colouring of the lawn during the first winter frosts
  • Helps development and radical hardening under thermal stress conditions
  • Strengthens resistance to fungal diseases and regulates aqueous turgidity

WHICH FERTILIZER TO CHOOSE AND WHAT DOSAGE TO USE?

The most common choice is to distribute from 30 to 50 grams per square meter of a good professional fertilizer with about 25 units of potassium and 20 units of nitrogen all slow release from programmed release systems not affected by humidity and rain (example: Autumn K).

In not very dense meadows it is also possible to use fertilizers with lower potassium and nitrogen titres (example: Slow K). However, there is a risk that the lawn will be a little nutrient depleted in spring. In this case we will take care to anticipate the spring fertilization a little bit.

SUPPORTING CHLOROPHYLL PHOTOSYNTHESIS

A typical problem of the winter season derives from the setting of the light and the lowering of the sun on the horizon which leads to a greater exposure of the lawns to the shade effect: the lawn stretches, thinns and reduces the root system.

To avoid this, it is advisable to carry out a couple of biostimulant treatments with algae derived products (example: Pre Stress) which counteract this phenomenon very well, bringing order to the growth of the turf. In the case of Prestress, it should be given to dry leaf in a dose of 150/300 ml to be diluted in 10 litres of water per 100 sqm.

SMALL BUT IMPORTANT TRICKS

Finally we see two small expedients that can give so much health to our beloved turf during the end of autumn and winter:

  • Rake it. Pine leaves and needles are the lawn’s enemies in autumn and winter. They reduce light absorption and gas exchange. Keeping the lawn clean is very important.
  • You can use spider rakes or blowers / vacuum cleaners to do this quickly and well.
  • Cutting. The grass height in autumn and winter should be increased by 20% to increase the ability to produce energy. For example, a meadow with fescue arundinacea should be cut to 6 or 5 cm.
  • Remember that it is equally important to prevent the lawn from exceeding 9 cm in height during the winter: in this case the lawn should always be mowed.
