Lawn Aeration and Seeding in Portsmouth

Most people understand how sunlight, water, and fertilizer contribute to grass growth. But lawn aeration often gets overlooked as an aspect of good lawn care. We conduct core aeration using a small machine that pokes thousands of holes in your yard, pulling out small plugs of soil. Though this might sound strange, fall lawn aeration on a yearly basis is a key maintenance practice for a robust yard.

Lawn aeration and seeding in Portsmouth benefits include:

  • Reducing soil compaction from being walked on throughout the year.
  • Fostering deeper root growth.
  • Allowing air, water, and nutrients to more easily reach the roots of your turf.
  • Increasing water absorption (and reducing water runoff).
  • Decomposing thatch buildup on the surface of soil.
  • Greening grass.
  • Helping grass naturally outcompete weeds.

In tandem with fall core aeration, we spread grass seed over your lawn that helps to fill in gaps and prevent weeds from gaining a foothold. The end result is a lawn that’s ready to handle dormancy in the winter, bounce back in the spring, and thrive in the summer.

5 Star Review

As a real estate broker and property manager for the past 40 years I can say that my relationship with this company has been phenomenal. We’ve been using allegro personally and professionally for over 20 years on multiple properties. They have always delivered their services on time and we love their communication. The value of their service is exceptional, I learned long ago that their lawn programs are far more economical than for me to do it myself. Our lawns look fantastic!!
