Lawn Care

1. Scarify 

Scarifying simply means raking up dead grass and moss to reduce layers of thatch. this is so that the thatch will not prevent water and fertiliser form getting through to the roots and soil

2. Trim back lawn and bed edges 

During the summer of warmth and sunshine, your lawn edges may have gotten a little bit overgrown, this makes it the perfect time of year to trim back those lawn edges.

3. Aerate your lawn 

The process of aerating is spiking the lawn to allow more air (and nutrients including water) to get to the grass roots. Aeration will also help your lawn survive through more extreme conditions such as waterlogging or drought.

4. Fork compacted areas

Due to heavy traffic in the summer, the lawn will need forking to break up the soil and improve the drainage when the rain starts to pour. Ensure that you push the fork four to six inches to the ground to get the proper aeration and drainage.

5. Apply Autumn Weed & Feed product 

Once your lawn is treated and in pristine condition, it’s important to get some lawn feed down to ensure that the roots are still growing strong throughout the winter.

Pests & Disease

Warm and damp weather is the perfect combination for pests to thrive. Clearing out debris from containers and disposing of old compost (which can harbour soil-borne pests like vine weevil) will go a long way!

Pests to watch out for this Autumn:

  • Cabbage Aphids
  • Slugs
  • Vine weevil
  • Brassica whitefly
