April Lawn Care Tips

5 min read

summer is finally here

The British weather can take its toll on our poor garden lawns. From frosty winters to springtime showers, our soils and grasses need a bit of assistance to make it through to the other side. Over-seeding, aeration and fertilising are all great ways to keep your lawns healthy. The best time to over-seed an existing lawn is in spring and autumn, with germination taking 7 to 21 days in ideal conditions.

Find out what lawn care jobs to do in April. When to sow your lawn seed. How often to water and mowing guidance, to ensure that your lawn looks good and performs well all year round.

Spring has well and truly sprung and everything in the garden is growing. Here are our April Lawn Care Tips to help your lawn look its best all year round.

April Lawn Care Tips at a Glance

  • Scarify to remove dead matter
  • Aerate for strong growth and water-wise gardening
  • Spot treat any weeds
  • Control moss
  • Feed your lawn
  • Mowing in April
  • Over-seed any bare areas
  • Lay new turf

How to scarify your lawn?

If you’ve not already done so, April is the ideal time to tackle scarification. Scarifying pulls moss and dead matter out of the base of your lawn. It lets the air flow around the plant and helps with drainage. Just like a good spring clean.

How to aerate your lawn?

I like to aerate in spring and autumn. Lawns are shared all year round by dogs, grandchildren and grown up kids. It doesn’t take long for the soil to get compacted. Compacted soil is hard for roots to grow into and it doesn’t soak up rainwater particularly well. Aeration improves the soil and makes sure that when I apply lawn feed it won’t just run off the surface.

How to spot treat lawn weeds?

I’m not a big fan of using chemicals in the garden.  I certainly don’t see any point in applying them willy-nilly whether they are needed or not. So for me, one of those “weed and feed” products is a no-no.  I prefer to dig weeds out whenever possible. If there are too many unwanted plants to uproot, use a glyphosate stick or something similar to treat them individually.

Good lawn care will make it harder for weeds to establish so make sure you keep up to date with your mowing and feeding regimes.

Moss control in April

If you scarify your lawn regularly, moss in your lawn shouldn’t be a problem. However I’ve included in our April lawn care tips because it can be a devil to control.

If moss is a major problem in your lawn, now is a good time to apply Ferrous (Iron) Sulphate to your lawn. Scarify first to get rid of most of the moss, and then sprinkle on the Iron
Sulphate. Within a few days any remaining moss will have died.

A bonus feature of Iron Sulphate is that it helps create a lovely deep green colour in your lawn.

Iron Sulphate is available in garden centres but isn’t always on display – you may need to ask.

Feed your lawn in April

I can’t stress enough the importance of feeding your lawn in April. Plants are growing fast at this time of year and they need nourishment. Without essential nutrients, lawn grasses become thin, pale and vulnerable to common lawn diseases.

If your lusciously-green lawn is looking not so luscious, or there are thinning/bare areas then it could be time for you to start applying grass seed and lawn feed.

April lawn mowing regimes

Expect to be mowing your lawn once a week at the beginning of April and increasing the frequency to once every 3-4 days by the end of the month. It is better to mow little and often than to let your lawn get lanky and then scalp it.

Over-seeding bare areas of your lawn

It’s not unusual to have some bald bits in your lawn at the end of winter. Over-seeding an existing lawn is a recognised essential part of annual lawn maintenance. First tackle the cause of the problem (commonly shade or soil compaction). Next loosen the surface of the soil with a rake and sow some good quality lawn seed. I would recommend a sowing rate of 3 grams per square metre. Cover with a very fine layer of compost.

April, or early spring, is the best time to over-seed your lawn. Typical daily temperatures need to be more than 13ºC for grass seed germination to be successful.

Try to protect the seed from hungry birds and keep the area moist until the new shoots are growing strongly.
