In regards to benefits of aerating.
Core aeration releases compaction of the soil allowing for water and nutrients to absorb into the ground, Oxygen to reach the roots, and allows gasses to escape. As someone else posted, it is part of total turf maintenance, and without core aeration, anything else you do is wasted time. Watering and fertilizing for an example will just run off into the drainage ditch since it cannot absorb into the turf. When the water and fertilizer is able to penetrate the ground you get deeper saturation, there for the roots will grow straight down into the ground where it is protected from exposure. On soils that are not aerated properly, only the top layer gets water so your roots have to grow upwards to get nourishment, building a thatch layer, and getting exposed to the heat.
You only want to use a aerator that pulls a true core so the compacted soil can expand. A spike aerator only pushes the soil to the side causing the soil to become more compact, thus defeating the purpose.
In regards to the moving sale, we are still looking for a serious buyer for the property we are on now. Once we sale the property and move into a new facility, we will cancel the sale. The purpose of the sale is to eliminate the amount of product we have to move and keep up with. We have already raised the prices on the items that sold well this summer.
