Nuances in operation

Although feeding grass with cut off plant tops after they decay seems like an effective idea, in practice, not everything happens as it should. The fact is that mulch will not always rot. In some cases, it can simply dry out and turn into hay.

Here are a few points to consider when working with a lawnmower that has mulching:

  1. It is not recommended to pour out mulch on a hot summer day. In this case, the remnants of dried grass will simply become garbage. In this case, it would be better to remove them.
  2. It is recommended to carry out such a mowing of grass in the spring or autumn. At this time, lawn plants most in need of fertilizer supplementation.
  3. When plants survive frosts, in the spring they begin to grow sharply. Mulching in this way during this period is not recommended. This is due to the fact that the grass stems grow coarse and represent poor-quality raw materials for the formation of humus. In addition, such stems are unlikely to decay, rather, they simply dry out and turn into garbage without becoming fertilizers.
  4. It is not recommended to work with such a lawn mower immediately after heavy rain, due to the fact that it is unlikely that it will be possible to mow wet grass growing on wet ground with high quality.
