Now that winter is (almost) over and the temperature is rising, we can get working in the garden again. There’s nothing more calming and grounding than digging in the garden and tending to your lawn, is there?

In fact, the Royal Horticultural Society recently discovered that gardening significantly decreases depression and anxiety while boosting social function. 

So, it’s time to emerge from our winter hibernation and get active in the garden once more. 

Have you missed it? I have! That’s why in this blog, I thought I’d explain which jobs you can do in March. 

Happy gardening, everyone!

What to do with your lawn in March?

Your lawn is coming out of hibernation, and temperatures are slowly rising above 10 °C again. That means it’s time to brush off the gardening boots and get focused on lawn care again. 

These are the tasks I recommend for March:

  • Do a soil acidity test and apply lime
  • The first mowing
  • Scarify

Do a soil test

Tip: buy a soil test and measure the pH value of the soil. 

At the end of the winter, you should check the state of your soil. Your soil’s acidity increases each year, and a winter with lots of rain like we’ve just had tends to accelerate the process. Also, heavy clay or sandy soils tend to have high naturally high acidity levels. 

Grass prefers soil with a neutral pH, so the more acidic your earth, the more inhospitable it is to your grass plants. So, if your lawn has become overwhelmed with weeds and moss, it’s likely to be an issue with high acidity. 

Carry out a soil test to ascertain your lawn’s pH level – a pH of between 6 and 6.5 is ideal. If your soil’s pH is lower than 6, you can restore the neutrality by spreading Lawn Lime

Scattering lime

Lime contains a lot of calcium, which increases your soil’s pH level, and by spreading lime over your lawn, your grass will grow faster than moss. 

Lime also helps your soil absorb fertiliser – so spreading lime will increase the efficacy of your lawn feed.

Wait at least three to four weeks before fertilising your lawn after you’ve spread lime because calcium in the lime binds together with nitrogen in your fertiliser. This prevents your lawn from absorbing nutrients. 

And that, of course, is a waste.

Lawn mowing

When your grass is too long, it can lay flat, restricting air circulation. So, as soon as your grass starts growing, you can mow. 

For the first mowing, cut your grass no shorter than 6cm. Make sure you remove all grass clippings, which can choke your soil if left on the lawn surface. Additionally, grass clippings may prevent your fertiliser from absorbing into the ground – so make sure you rake them away.

Remember: never cut your grass blades more than ⅓ of their length. And use sharp blades – blunt blades will tear the grass and damage it.

Scarifying the lawn

There’s a good chance that moss has infiltrated your lawn over winter. With lots of rain and so little sunshine, moss can grow rampant. 

Moss suffocates your lawn, and water, light, and nutrients can no longer find their way to the soil. So, it’s a good idea to scarify. 

Scarifying is an essential maintenance task that removes moss and dead organic material from the soil surface. You effectively comb the organic material out of your lawn, but initially, it can look a bit like you’ve destroyed your lawn. 

Don’t worry, though, because your lawn will quickly recover. And within two weeks, your lawn will look beautiful, strong, and vibrant. 

Note: only scarify when the lawn is actively growing. So make sure the temperature is over 10 degrees and your grass has already started growing.

Tip: Sprinkle ferrous sulphate before scarifying. The added iron sulphate increases resistance and helps the lawn recover after its winter dormancy.

I wish you lots of gardening pleasure!
