Summer Lawn Care: How to Look After Your Lawn in Heat

summer lawn care

Summer lawn care is really about keeping on top of all the hard work you put into your lawn in the spring.

If you did all the jobs that needed to be done in the spring, your lawn should be in good shape.

Summer should really be about reaping the benefits of that hard work. Spending time in your garden with friends, family and pets is all part of the enjoyment of gardening.

All that being said, summer can be a stressful time for your lawn as temperatures rise and rainfall becomes infrequent.

But fear not, my summer lawn care calendar will show you how to keep your lawn looking at its very best all summer long.


When Should I Start My Summer Lawn Care Jobs?

As I said, summer lawn care should just be a case of keeping on top of what you did in the spring.

If you raked and scarified in the spring, your lawn will need time to recover.

If there isn’t much rain to help aid recovery you’ll need to water.

Once your lawn has recovered, summer lawn care should start. For the most part, there really won’t be too much to do.

That said, if your lawn was in bad shape coming out of the winter and you didn’t fix the issues in spring, it won’t improve during the summer.

Don’t be tempted to tackle jobs like scarifying or removing large amounts of moss in the summer. Chances are that it will be too hot and dry for your lawn to recover from such invasive treatments.

Your best bet would be to wait until the autumn when growing conditions are at their best. Then renovate your lawn with an autumn lawn care program and keep on top of things over the winter.


The Tools You’ll Need For Summer Lawn Care

Here are the tools you’ll need for summer lawn care:



The most important tool in a lawn owner’s shed!

Despite the fact that grass growth usually slows in the summer, you’ll still need to cut the grass to maintain a healthy lawn.

It’s still the most important job.

Spot Spray Selective Weed Killer

spot spray weed killerBy ‘selective’ I mean a weed killer made for use on lawns.

You should have treated your whole lawn with a selective weed killer concentrate in the spring. I recommend using Weedol for this.

This should mean your lawn should be relatively weed free. A spot spray will kill the odd weeds that appear during the summer.

For a spot spray, I recommend Resolva. It has a different active ingredient to Weedol so by using the two, you’ll be able to kill a wider range of weeds.

Summer Lawn Feed

A good, slow release summer lawn feed will feed your lawn through to the autumn.

You can also, give it a quick boost of green with a liquid feed.

Fertiliser Spreader or Watering Can

That said, if it’s any larger than 30 square meters, spreading it accurately can prove difficult.

In which case, use a fertiliser spreader. You can buy smaller, handheld spreaders for smaller areas or larger, broadcast spreaders for big lawns.

Or, if you apply a liquid feed, you’ll need a watering can, preferably with a sprinkle bar attachment.

Hose and Sprinkler

This will help to keep it looking green and lush.

You’ll also need to water if you apply a granular lawn feed, not only to activate it but also to prevent it from scorching the grass.


4 Summer Lawn Care Jobs

As I said, summer lawn care isn’t very intensive.

Here’s what you need to do to keep your lawn in tip-top condition.

Keep Mowing the Lawn

Despite the fact that grass growth usually slows down in the summer, you should keep cutting it regularly.

That said, you can mow less frequently, every 10 days as opposed to every 5-7 like you would in the spring.

Also, keep the mower set a little higher during the summer and never cut off more than a third of the grass leaf. This keeps the water in the leaf and reduces the risk shocking the grass which can cause it to go dormant, even kill it.

Regular mowing prevents the grass from growing upwards so it is forced to grow sidewards via new roots and shoots. This, in turn, creates a thicker, denser lawn.

If your lawn mower has a mulching attachment, much the grass and leave the clippings on the lawn. Doing this will keep all the moisture and nutrients in those clippings there for the lawn to consume again.

Keep On Top of Any Weeds with a Selective Spot Spray Weed Killer

killing weeds in the summer

If you treated the whole lawn with a selective weed killer concentrate in the spring, your lawn should be relatively weed free.

That said, there are plenty of weed seeds floating around in the summer.

Check your lawn weekly for any new weeds and give them a blast with a spot spray selective weedkiller like Resolva.

If you don’t like using chemicals, you could extract them using a weed extractor. However, weeds like dandelions will grow back if you don’t remove the whole root.

Apply a Summer Lawn Feed

If using a granular lawn feed, apply it 3 months (or as near as you can) after applying a spring lawn feed.

For example, if you applied your spring feed in the second week of April, wait until the second week of July.

You can also apply a liquid feed to give your lawn a boost if and when it needs it.

One caveat when it comes to feeding your lawn in the summer…

If the weather is baking hot and it has been for a long time (like it was in the summer of 2018) don’t feed your lawn at all. The high Nitrogen content in summer lawn feed can scorch the grass in drought conditions, doing more harm than good.

If you water your lawn weekly, apply the fertiliser and then water it in.

Water The Lawn, Weekly, If Needed

water the lawn in summer

In order for your lawn to stay as healthy and as lush as possible, it needs about an inch of water a week.

If it hasn’t rained for a couple of weeks, turn the sprinklers on (if the grass is still green) and water once a week, in the early morning to an inch depth. Put a straight-sided tray out on your lawn and once there’s an inch of water, turn the sprinklers off.

If your lawn has already turned brown and gone dormant, leave it and it’ll spring back to life again when the rains come in autumn.

Watering to an inch deep should take around an hour.

This will prevent the soil in your lawn from completely drying out and becoming impenetrable by water.

Like I said, water once a week (provided there are no hosepipe bans in your area), in the early mornings. Don’t water lightly every evening like you see your neighbours doing. This can cause more problems than it solves. Not least the onset of fungal diseases.

Also, if you have dogs, especially female dogs that use your lawn as a toilet, it’s a good idea to spray the areas they have pee’d on. This will prevent those areas from turning into unsightly brown patches.

In Conclusion

I’ve said it several times now, but summer lawn care should be pretty easy if you have done the jobs that needed doing in the spring.

Now’s the time to really enjoy your lawn and just do the little bits to keep it looking nice and healthy.

However, summer is not the time to take the jobs that should have been done in spring. Wait until autumn.
