There are two basic types of aerification, hollow and solid tine. With hollow tine a soil core is removed, while with solid tine aerification a hole is created and no core is removed. With both types, a void in the soil is created that allows air and water to more deeply penetrate the root zone. The aeration benefits are longer lasting with hollow tine (pictured) due to the removal of the core. CAES News
Room to Grow
Last year many lawns across the state didn’t receive enough rainfall for the grass to grow, photosynthesize and make carbohydrate reserves. Turfgrass that experienced this lack of rainfall will likely be slow to green up this spring. If rainfall totals return to normal this spring, lawns will recover, but they may do so at a slower rate because the production of reserves was compromised last fall. For example, a lawn that would typically be fully green and growing in mid-May might take until late May or June to green up. A two- to four-week delay in green-up of warm-season grasses may be common this spring.

Gardeners all over the country can enjoy the amaryllis, whether in the landscape or as one of the most-loved Christmas plants forced indoors. Outdoors they prefer fertile, well-drained soil. Ours get morning sun and late-afternoon shade. In the landscape, we treat them much like narcissi. We will deadhead flowers and leave foliage until it wants to go dormant.
