Core AerationCore Aeration

Having your lawn aerated is the best natural way to improve the overall health of your lawn. Core aeration removes small cores or “plugs” from the lawn, which break back down into the turf after a week or so. These plugs encourage microbial decomposition of undisturbed thatch to help accelerate thatch breakdown. These plugs help revive compacted soil and completely puncture thatch build up in concentrated areas.

Aeration allows water, oxygen, sunlight and fertilizer to penetrate the turf and reach the root system while improving health and encouraging growth and expansion. Aeration can be done any time the lawn is soft and in an active growing state (mainly late spring or early fall). Recommend aerating on an annual basis to consistently encourage a healthy lawn.

Why is aeration necessary?

In most home lawns, fertile topsoil may have been removed or buried during excavation of the basement or footings, forcing grass to grow in subsoil that is more compact, higher in clay content and less likely to sustain a healthy lawn. Core aeration allows air, water and fertilizer to better reach the root zone. This stimulates root growth to create healthier, stronger 1ringturf grass plants.


What are the benefits of aerating?Core soil plug

Core aeration can help make your lawn healthier and reduce the maintenance requirements through these means.

  • Improve air exchange between the soil and atmosphere
  • enhanced soil water uptake
  • improve fertilizer uptake in use
  • reduce water runoff and puddling
  • stronger turf grass roots
  • reduce soil compaction
  • enhance heat and drought stress tolerance
  • enhance thatch breakdown


How often should lawns be aerated?

Most lawns benefit for annual aerations. Heavily used lawns, or those growing on heavy clay or subsoil’s may need more than one aeration each year.


What can you expect?

Immediately after an aeration, your lawn will be dotted with small plugs pulled from the soil. Within a week or two, they break apart and disappear into the lawn.
About 7 to 10 days after aeration, the holes will be filled with white actively growing roots – a sign that the turf grass is receiving additional oxygen, moisture and nutrients from soil.
On compacted soils and on lawns with slopes, you should see an immediate difference in water puddling and runoff after irrigation or rainfall. After aeration, your lawn should be able to go longer between waterings, without showing signs of wilt.


Over seeding & Slit-Seeding

These services incorporate new grass seed into an existing lawn to thicken the turf. Over seeding is the process of spreading grass seed over the lawn with a spreader and watering the seed into the soil. We usually aerate the lawn at least two times before spreading seed in order to encourage more seed-to-soil contact. If select areas have poor grass establishment, additional top soil may be required to help the lawn look its best. Slit-Seeding is the process of introducing grass seed directly into the soil by using a machine to cut rows of small trenches in the soil and physically place grass seed in the trench before covering it back up with top soil.

This helps ensure seed placement and is usually used in high runoff areas. Timing and proper care are essential for the establishment of any new seed. The ideal time to plant new seed is in the late spring or early fall when temperatures are moderate. Applying a starter fertilizer encourages early root development and expansion. Every lawn has unique characteristics that determine the best approach for introducing new seed. Contact Dream Green for a free consultation to find out how to get your lawn looking its best.


Lawn Renovation & Restoration

While lawns in Minnesota tend to be considered among the best in the country, they tend to take a lot of abuse. Our climate changes drastically throughout the year and is experiencing more and more droughts and heavy rain periods. This means lawns need regular care to thrive and sometimes, depending on their unique characteristics, may need to be renovated or restored.

A general rule in the green industry is that if a lawn needs more than 50% restoration, it may be time to start over and plant a new one. When renovating a lawn, we generally select from several methods of care (dethatching, aerating, etc.) to best suit the individual lawn. If you are unsure about what your lawn requires to be the best on the block, please contact Dream Green for a free consultation.
