Before the winter you should strengthen the lawn with an autumn fertilizer. From September to early November, the fertilizer can be applied and then acts for up to ten weeks. In this way, the green carpet is well through the cold season and can start full again in the spring.
For professionals, fertilization with a special autumn fertilizer has long been an integral part of their annual gardening. Damaged lawns such as golf or sports fields are usually supplied from mid-October with an autumn fertilizer. Even if your own lawn is not subject to these special stresses, it is particularly sensitive in winter. In snowy years, the danger increases that under the snow cover lawn diseases such as the snow mold spread. But even very cold winters without snowfall are anything but optimal, because frost-free grass is particularly strong for the grasses. Through the gift of a special autumn fertilizer, the lawn can store power reserves, through which he quickly turns green again in the spring. In addition, autumn fertilizers contain a lot of potassium, which strengthens the disease and frost resistance of the grasses.
Long-term fertilizers, which are used in the spring, are mostly nitrogen-stressed and should not be used in autumn, because the high nitrogen content stimulates growth. The susceptibility of the lawn to diseases and frost would only be favored. Although turf fertilizers also contain nitrogen, the proportion is so low that only potassium intake is promoted. Potassium acts as a de-icing salt in cells: the higher the concentration, the lower the freezing point of the cell's juice is. The leaves of the grasses remain flexible even in light frost and do not freeze immediately.
Tips for lawn care in autumn
If the fall foliage is too long on the lawn, the grasses under it get too little light. That is why the leaf rake should be used regularly
- Remove the autumn leaves regularly. It robs the grasses of light and under the leaves creates a humid microclimate, favors the fouling and fungal diseases. The withered foliage should be raked off once a week. Tip: You can also record it easily with a highly adjusted lawnmower. The rotating knife creates a suction that transports the foliage into the catcher
- In frost and hoarfrost the lawn should not be entered. The frost causes ice crystals to form in the plant cells. If the frozen blades of grass are now strained, they break off and turn brown. The lawn usually recovers from it only in the spring. Sites that are regularly entered in the winter, often even be reseeded
- Mow your lawn one last time in November, using the same mowing adjustment that you used all year round. If the lawn goes too long into the winter break, it is easily attacked by fungal diseases. If the pruning is too deep, adequate photosynthesis can not take place
