A lush, green, and healthy lawn can be one of the most rewarding aspects of home gardening, but it requires regular care and maintenance to reach its full potential. Aeration, an essential part of lawn care, is the process of perforating the soil with small holes to allow air, water, and essential nutrients to reach the root system. One of the most effective lawn aeration methods is hollow tine aeration, which removes small cores of soil from your lawn to reduce soil compaction. In this guide, we'll discuss the best time to hollow tine aerate a lawn in the UK and share some tips to help you get the job done right.

The Importance of Aeration

Over time, the soil in your lawn can become compacted through foot traffic, pet use, mechanical equipment like lawn mowers, and natural processes such as the growth of grassroots. This compaction leads to a reduction in the available pore space for air, water, and nutrients, making it difficult for the grass roots to grow and expand.

Aeration can benefit your lawn by:

  • Improving soil drainage
  • Enhancing air exchange between the soil and atmosphere
  • Encouraging deeper root growth
  • Reducing lawn thatch
  • Stimulating microbial activity

When to Hollow Tine Aerate a Lawn

The best time to aerate a lawn in the UK largely depends on the type of grass present:

Cool-Season Grasses

For lawns with cool-season grasses such as bentgrass, fescue or ryegrass, the optimal time to aerate is during autumn. Aeration during this period will give the grass the best opportunity to recover from the aeration process and ensure the roots benefit from added nutrients before the colder months set in.

Warm-Season Grasses

Warm-season grasses like buffalo grass or zoysia grass should be aerated during late spring or early summer. Aeration during this period allows the grass to recover quickly and take advantage of the favourable growing conditions.

Tips for Hollow Tine Aeration

To make the most of this lawn care process, here are some essential tips for hollow tine aeration:

  1. Timing is crucial: As previously mentioned, aim to aerate lawns with cool-season grasses during autumn and warm-season grasses during late spring or early summer.
  1. Preparation: Mow the lawn a few days before aeration, and ensure the lawn is moist enough to make the tine penetration easier.
  1. Proper tools: Consider using a hollow tine aerator with 3 or 4-inch deep tines, spaced 2 to 4 inches apart. Renting or purchasing the right equipment can significantly improve the effectiveness of the procedure.
  1. Fertilising and watering: After completing the aeration process, apply a high-quality lawn fertiliser and water the lawn thoroughly, as this will promote recovery and new root growth.


Hollow tine aeration plays a crucial role in maintaining a healthy lawn, providing air, water, and nutrients the opportunity to reach the grassroots. By identifying your lawn's grass type and following the recommended aeration timeframes, you can rejuvenate your lawn and keep it looking lush and green all year round.
