Looking After Your Lawn This May

Looking after your lawn in May is all about setting it up for a lush, green summer. With longer days, warmer tempatures, and a good mix of sun and rain, grass really takes off this month. Here are your top lawn care tips:

 

🌱 1. Mow regularly—but don’t scalp it 

  • Mow once or twice a week depending on growth. 
  • Keep the mower blades high at the start of May, then gradually lower as the month goes on. 
  • Aim to cut only one-third of the grass height at a time to avoid stressing it. 

 

🌿 2. Feed the lawn 

  • Use a spring/summer lawn feed high in nitrogen to boost green growth. 
  • Apply after rain or water it in well. 
  • Avoid feeding just before a dry spell unless you can water it in properly. 

 

🌧️ 3. Water if it’s dry 

  • Most lawns don’t need much watering in May, but if we get an early dry spell, give it a deep soak once a week. 
  • Water early morning or evening to reduce evaporation. 

 

🍃 4. Remove weeds 

  • Dig out dandelions, daisies, and plantains by hand or use a selective lawn weedkiller. 
  • Try to deal with them now before they flower and spread seed. 

 

🌾 5. Overseed patchy areas 

  • Rake out dead grass, scatter lawn seed, and lightly rake in. 
  • Keep moist until it establishes (usually 2–3 weeks). 
  • May is a perfect time for this—warm soil and regular rain help it take. 

 

⚒️ 6. Scarify lightly if needed 

  • If you didn’t scarify in early spring and your lawn is still very thatchy, you can do a light scarify now. 
  • Too much raking now can stress the grass as it’s growing fast—go gently! 

 

🧽 7. Aerate compacted areas 

  • Use a garden fork or aerator to spike the lawn in heavy or waterlogged areas. 
  • Improves drainage and lets roots breathe. 

 

🐜 8. Keep an eye out for pests 

  • Look for signs of leatherjackets (crane fly larvae) or chafer grubs—like birds pecking the lawn or yellow patches. 
  • If there’s a real problem, you can treat with nematodes later in summer (but now’s a good time to observe). 

 

🌼 9. Edge the lawn 

  • Neaten up lawn edges with a half-moon edger or spade. 
  • Clean edges make a massive difference visually and help prevent grass creeping into borders. 

 

🐝 10. Go a little wild (optional!) 

  • Consider leaving a patch of lawn to grow longer to help pollinators—“No Mow May” is a real thing! 
  • Even a small wild patch can support bees and butterflies. 

 

This Month's Key Tips
  • Mow lawns weekly.
  • Plant out summer bedding towards the end of the month, when the weather gets warmer.
  • Open greenhouse vents and doors on warm days.
  • Watch out for late frosts. Tender plants will need protecting.
  • Water early and late to get the most out of your water, recycle water when possible.
  • Check for nesting birds before clipping hedges.
