June 2022 Lawn Diary

This Month in a Nutshell

Apart from a few easy jobs just enjoy the garden and some very welcome warm sunny weather.

Summary 'to do' list for now through June:

  • Fertilising
  • Pest and disease control
  • Weed Control
  • Repair damage caused by wear and tear

The Weather

Still a bit of a struggle in many places due to the dry weather with a few of you contacting us with problems getting seed to germinate. If you are having problems we have a new section which should help you get on the right track otherwise feel free to email our Technical Support team. Please visit Grass Seeding Techniques and Problems

With more frequent long dry spells the lesson is... take every opportunity in good conditions to improve the health (and therefore drought tolerance) of your lawn with good lawn care practices including aeration, fertilisation, weed control and seeding!

So onwards and upwards to what looks like a wonderful month of gardening, mowing, BBQ's and the great outdoors...

June long range forecast courtesy of the Met Office:

28th May to 6th June
Over the weekend, fine and dry weather with clear and sunny spells expected for most, however some cloud and light showers remain possible, especially in the north and east. Despite a chilly start on Saturday, near normal temperatures can be expected for most, perhaps feeling warmer in the south and southwest. Into the following week, the weather is likely to become more settled, with any few showers most likely to be seen in the north and east, where it may feel fresher and cooler. This means above average temperatures away from the north and east, with drier conditions expected for most. As we move into the beginning of June, drier than average conditions are expected to persist overall.

7th to 21st June
In the beginning of June, we can expect to see a lot of dry weather across the UK. Temperatures may potentially become warm in the south and southwest but remaining closer to average in the north. Later on in June, we may however see some less settled and cooler weather, particularly in northern regions.

Mowing the Lawn

Regular mowing is the key to a great lawn. With June temperatures and a little moisture, growth should be at its best so regular mowing will produce a beautiful dense turf. Regular means at least once a week.

If conditions are or become dry then growth will be slow but do mow at least every 10 to 14 days to control coarse grasses and seed heads.

Finally adjust your mowing height to suit the growing conditions.


For the mowing season you need to do two things: keep it clean and keep it sharp. If the grass is lush or damp it can easily build up inside the mower so always give the mower a good brush, scrape or hose down after every use. Secondly, if you do a lot of mowing, then be prepared to sharpen or swap blades mid-year to maintain a clean cut.

Fertilising the Lawn

If this is your first application of the year use a 2-3 month slow release Spring & Summer fertiliser. It has good grass safety and will take you through until the autumn.

Similarly, if you made an early spring application of spring & summer fertiliser you should be considering your second application about now. Alternatively using liquid fertiliser every 4 to 6 weeks allows more control for the lawn enthusiast. Timing will depend largely on what and when you applied previously, recent growth and rainfall. If soil moisture is available and growth has slowed with some loss of colour then consider an application to maintain looks, colour and health.

If you gave your lawn a feed with Lawnsmith® Extra-LONG fertiliser in spring you're sorted and your next feed should be in autumn if desired.

Weed Control

Weeds should be well on the way now so this is a great month for applying weed killer to the whole lawn either by knapsack sprayer or watering can if you have not already done so. If you're using a watering can try the weed & feed sprinkle bar for faster more accurate application.

If you've been diligent with your weed control and have few weeds then keep at it with a combination of spot treating individual weeds with a Ready to Use Weed Killer or manually removing any obvious large weeds.

See Weed Identification for more detail and control methods.

WARNING: Do not apply weed killer to dry or parched lawns other than as a spot treatment.

Moss Control

Wait now until autumn.

Watering the Lawn

If you water this month do it in the mornings to reduce the likelihood of red thread. This is also the time when dry patches or fairy rings start appearing in the lawn. They can easily spoil an otherwise great looking lawn so a little effort in this direction pays dividends. Some watering, a little very shallow spiking and applications of wetting agent is all that will be required from now until perhaps August. See Pests and Diseases below.

Aeration & De-compaction

As discussed in Lawn Aeration Advice, aeration is highly beneficial if done properly. If conditions allow, using lawn aerators such as a rolling aerator or aerator sandals makes it the job relatively easy. At the very least you should be looking to use a fork on the most trafficked areas around clothes lines, path-to-lawn entry points, kid's goal mouth and postman's shortcut. Add grass seed and fertiliser to any worn areas after aeration then water thoroughly.

Please note that it is now too late to be slitting or using a hollow tine aerator. These increase drying so if conditions are or become dry you are just compounding the problem.

Raking & Scarifying

Wait until autumn.

Repairs & Renovations

The late spring and summer months are the time the lawn is used most. If children and teenagers are enjoying playing outdoors then damage can soon occur. Getting on top of it early is a wise move. Rotate areas of use if possible and then water, spike and fertilise heavily used areas. Do the same for worn areas but with the addition of about 10 to 20 grass seeds per square inch.

Renovation requires water to help the grass repair and recover so only undertake renovation and seeding if you can water if conditions are or become dry. Any turfing laid will require regular watering to establish.

Pests & Diseases

The disease to watch out for from May onwards is red thread; occurring as humidity levels rise causing severe disfiguring of the grass leaves. There are ways to reduce its impact with the careful use of watering and fertiliser so read the red thread advice.

In addition, if your lawn suffers from 'dry patch' or 'fairy rings' then as the lawn dries these will become more evident. Watering, very light spiking, fertiliser and a wetting agent will go a long way to relieving the problem.

Chafer Beetles may also be seen around the garden. A very common insect throughout the UK and Europe hatching in May to June - hence the name June Bug! If you see large numbers, have a read of our Chafer Grub advice as this may indicate a forthcoming lawn problem.

Finally, this is the month ants become very active so if hills start forming in or around the lawn you'll need some ant bait stations or ant-stop granules. The granules are brilliant for stopping the ants in their tracks but do be careful with the concentration - more is not necessarily better! The bait stations are best used as a preventative measure after using the sachets.

Rolling the lawn

Unlikely to be required until next spring unless you've over sowed.

Top Dressing

Top dressing is an advanced lawn care procedure to reduce thatch and smooth the lawn surface. If you are not a lawn 'nut' then I suggest you don't need to bother!

If you are, then you should have your first dressing done and may be considering a second around now. Not a problem if there is plenty of moisture and growth is good. Application rates and frequency will vary depending on your goals and type of lawn so please read our top dressing advice.

The New Lawn

With potentially dryer months just round the corner put this off until autumn unless you can water the area daily.
