Lawn Update – September 23rd

Autumn weather is certainly starting to take hold with cooler, wetter weather and the nights are drawing in very rapidly, being dark for 1945 by now.

15th September (1600):

  • Air temp = 16.1C; Soil temp = 13.0C
  • Grass height: ranged from 55mm – 65mm; averaging 60mm
  • Waste clippings: 1/3rd of a box

I measured the size of the mower box to help give an indication of the total volume of grass clippings I will have removed during the year when I carry out the calculation in a month or so ( 25cm x 30cm x 30cm = 0.0225m3).

There was a small amount of earthworm casts on the surface of the lawn, but this is only to be expected at this time of year with good soil moisture. This earthworm activity is a positive sign of a healthy rootzone.

A small amount of conifer leaves had fallen due to the relatively high winds.

22nd September (1330):

  • Air temp = 12.9C; Soil temp = 11.8C
  • Grass height: ranged from 55mm -70mm; averaging 65mm
  • Waste clippings: 1/4 of a box

Heavy dew during the day, so wet when mown.

Time to cut back any shrubs that are over hanging the lawn to reduce water dripping onto the lawn from the shrubs, plus to improve light levels and air flow to try and keep a relatively healthy surface to the lawn during this time of year.

I’ve been unable to carry out a suitable end of growing season lawn renovation, primarily due to wet conditions when I had available time, but I will be able to carry out some hand forking over the autumn time to help aerate the lawn – mind you, the earthworms are doing a pretty useful job for me.
