There are many ways that Core Aeration benefits lawns.
Watch a quick video demonstration of Core Aeration on the new CrabappleLandscape YouTube Channel.
1. Core Aeration loosens up compacted lawns, improving resiliency and cushioning
2. Increases soil pore space and oxygen needed for good growth of turf, improving air exchange between the soil and atmosphere
3. Removes thatch, a physical barrier to nutrient uptake and water infiltration
4. Improves root growth, creating stronger turfgrass roots
5.Limits run-off or puddling of rain and irrigation water, with up to 25% water savings
6.Provides better fertilizer penetration, delivering it right to the rootzone
7. Increases effectiveness and distribution of lime and gypsum
8. Stimulates new root development
9. Provides evenly spaced seeding holes for reseeding
10. Enhances tolerance of the lawn to heat and drought stress
What is Core Aeration anyway?
Core aeration is the removal of small cylinders of soil called "cores" from compacted lawns to control thatch buildup, allowing the rain and fertilizer to soak in and the roots of the turf to breathe and expand. An aeration machine pops out ½ inch tubes of soil and deposits them on the lawn where they soon dissolve.
What is thatch?
Thatch is a build up layer of cut grass clippings, dead roots and miscellaneous debris that settles at the soil level of the individual grass plants that make up a lawn, and is most common with warm-weather creeping turf varieties such as Bermuda and Zoysia.
When should I aerate?
Crabapple LandscapExperts can evaluate your turf and recommend this procedure if needed:
1. If turf is only shallowly rooted
2. If the lawn is heavily used, causing thin areas
3. If the thatch layer is thicker than ½ inch
4. If the soil is heavy clay
5. It is best not to aerate newly-seeded lawns
When is the best time to aerate warm season lawns?
Right now (March) and through June or July, when warm season grasses are coming out of winter dormancy and beginning a vigorous period of growth as the soils warm up. Lawns will recover quickly from aeration at this time.
What are the best practices for Core Aeration?
1. Soil is moist but not wet
2. The aeration machine is run in two different directions over the lawn for good coverage
3. Lawns can be aerated once a year, especially under heavy use
4. Soil cores are are best left on the lawn surface; they typically work back into the
grass in 2-4 weeks
5. Lawns may be fertilized and seeded immediately following aeration with or
without further soil top dressing
6. Crabapple LandscapExperts will mark sprinkler heads, shallow lines from
sprinkler, underground utilities, cable, and septic lines before aerating to make sure
they will not be damaged.
To get the lawns on your properties looking lush and green without shelling out a lot of money, the answer is core aeration. It only takes a day or two to complete and the results can be staggering!
