Spring is the favourite time of year for the Turfonline team.  Here are our essential lawn care jobs for March

  • Aeration
  • Scarification and Moss Management
  • Feeding
  • Mowing
  • Overseeding
  • Returfing

Aeration

Aeration is a technique used by greenkeepers to help water drain from the surface of the lawn (or playing surface) and to get more oxygen down to the plants’ roots so that the cells can do everything they should be doing.

A simple lawn aerator like this one is cheap to buy and does the job well. Although it may take quite a long while to aerate a large lawn. The holes need to be about 10cm apart across the whole lawn.

In very simple terms, aeration is about piercing holes through the grass layer and into the soil. It’s best done in spring and autumn when the soil is neither saturated nor dry.

You may have seen aeration done with a garden fork. That’s not something I’d advise. Yes, most of us do have a garden fork in the shed already and yes, it doesn’t require any technical expertise to stick a fork in the ground and wiggle it about a bit.  BUT by doing that you are actually compacting the sides of the “hole” even more than they were already. What you really should be doing is taking out a thin core of soil so that you can relieve compaction.

Help with aeration

Greenkeepers use a machine called a hollow tine aerator. If you only have a small lawn, you can buy a manual version of the same thing. Or, you could hire an aerator from your local tool hire shop.  Better still, if you’re pressed for time, hire a lawn care professional to do the work for you. They have all the right equipment and because they know how to operate it, they work fast and efficiently.

If you are on heavy clay soil, you could follow hollow-tine aeration with topdressing. That’s brushing a mix of 70% sand and 30% quality topsoil into the holes. It helps improve soil quality in the longer term.

Scarifying and Moss Management

Moss likes:

  • Poorly drained soil
  • Shade
  • Minimal competition from other plant species

To combat moss, you need to fix those 3 things.

By aerating (see above) and topdressing you will improve lawn drainage and make it harder for moss to reproduce.  Moss needs a thin layer of surface water to breed. I’ll not turn this blog into a biology lesson but basically, moss is a primitive plant that behaves very differently to grass and flowers.

Reducing shade on a lawn

Shade is hard to combat sometimes. I’m lucky enough to have a grown up Son who is competent with the chainsaw. This winter he has helped me lop some branches off the mature trees in my garden and reduce the height of the hedges. Hopefully, that will let more light into the more deeply shaded areas of my lawn. More light = stronger grass plants.

You can help keep moss under control by feeding the grass…we’ll look at that in a moment.

Scarifying

Scarifying is another essential lawn care job for march if your lawn. It’s especially important if your lawn is more than about 2 years old. Scarifying is like a deep clean. It rakes all of the moss, dead leaves and other debris out of the bottom of your lawn so that the soil and the grass plants can breathe.

You could, if you are very energetic, scarify your lawn with a spring tine rake. If I were you though, I’d either hire a scarifier or employ a lawn care professional to do the work for you. Me? I have a large lawn so I’ve invested in a petrol driven scarifier.

Moss really does spoil the appearance of a lawn. It also makes it spongy to walk on and no good at all for ball games.

Feeding your lawn in March

If you only have time for one lawn care job this march, make it feeding.

Grass plants need nitrogen, phosphorus and potassium to help them grow strongly, outcompete the weeds and look beautiful.

Harrowden Turf’s Vivid Green Spring/Summer Lawn Fertiliser will give your lawn the pop of nutrition it needs to help it recover from winter.  Feed in March/April and follow up with another feed after 8 weeks.  It’s easy to apply, cost effective and it does the job well.

Mowing

As soon as your lawn starts growing, you can start mowing.  Make sure the mower blades are really sharp. In fact, that’s something you could be doing while you wait for a sunny day. If you haven’t already serviced the mower, do it ASAP.

For the first mow of the season, keep the blades high. It’s not too late in the year for a frost and you don’t want to stress the plants too much.  Your aim should be to tickle the tops of the grass blades to help stimulate the grass to “tiller out” and grow thicker. “Tillering” is the term that farmers and gardeners use to describe how grasses grow extra blades to make the whole plant more robust.

I prefer to remove all of the clippings at this time of year.  My rule of thumb for grass clippings is “when it’s dry, let them fly”. I’m happy to return clippings to the sward, but not if they are going to sit on top of the lawn in big ugly clumps.

Overseeding

March through to May are also good months to repair any thinning or bare patches with grass seed. More on overseeding in this article

For shaded areas, overseed with a more shade tolerant grass variety. This will help the grass out-compete the moss.  I recommend Shadesman grass seed.

Returfing

Is your lawn so awful that you feel like ripping it up and starting again?  Read this blog before you decide.
