Lawn update 25th March

A nice bright sunny start to the day but very cold; heavy dew on the grass so I waited until later in the afternoon (around 3pm) before cutting the grass.

Before cutting the grass the height varied from 55mm to 90mm, which just shows the difference in some of the grasses present and also the microclimate present within the lawn as some of it is more shaded during the day than other parts. Some areas will therefore get more sun and warmth than others.

The height of cut was 40mm and I took around 1/3rd of a box of cuttings off the lawn.

Grass remove was about one-third of a box

The soil moisture content reading was half-way between 4 and 5 (I waited 60 seconds to let the reading stabilise, but I could have given it longer).

The soil temperature at 50mm depth was 9.3C, whilst the surface temperature had a reading of 12.8C (taken at 3.45pm); all readings were recorded in a shaded part of the lawn. The readings taken 8 days ago, by comparison, were 7.2C and 8.9C (although this was at mid-morning reading rather than later in the afternoon like today).

I’ve added a table of temperature and humidity data for the last 2-weeks for my general location:

The temperature is certainly starting to creep up and growth is becoming more regular, although the past week had significantly lower minimum temperatures than the week before. Spring lawn renovation will, however, probably be taking place over the next couple of weeks.

Field woodrush (Luzula campestris) was in flower on some parts of the lawn, so whilst the leaf looks a little like a grass plant from a distance, this is clearly not to be confused with a grass plant when it flowers.

I did notice a lonely, single plant of Wavy Bitter-cress (Cardamine flexuosa) on the lawn:
