Slice Seeding vs Over Seeding: What Is Best for My Yard?
Summer and dry weather can put a lot of stress on a lawn, especially a lawn that’s been established for several years. While this may sound counter-intuitive, it’s true — many of the grasses used to seed lawns years ago are considered inferior in terms of looks, disease resistance, and drought tolerance to the varieties commonly used today. Even if you’re finicky about maintaining your yard and follow all of the right lawncare tips, old grass can still end up looking the worse for wear.
What is the Difference Between Slice Seeding and Over Seeding?
Fortunately, most of these issues can be overcome by refreshing your lawn with slice seeding or over seeding. Which one is more appropriate for your yard depends on several factors, including how many bare spots need to be covered and how much thatch is matted between your existing grass and the soil.
Over seeding a lawn is a relatively simple process. The lawn is first core aerated to loosen the soil and relieve compaction, and the new seed is scattered over the lawn. It is best to rake in the plugs from aerating. Any seeds that falls into the deep aeration hole will not germinate. It is best for old lawns that still have a lot of cover– large bare areas don’t tend to respond as well to this method. It also works best with bunch-type grasses, versus grasses that reproduce by setting down runners.
Slice seeding is slightly more complicated, and best used to fill out a thin, weak lawn or refresh a lawn that doesn’t have too much densely-matted thatch. Often a thin lawn occurs when there is a build up of thatch. It is best to dethatch first and then slice seed, leaving the thatch will create a breeding ground for pests and will reduce the penetration of rainwater to the soil level. With this method, grass seed is placed into the hopper of a slice seeder that is then run over the areas of the lawn to be seeded. It cuts straight furrows into the grass, through the thatch and into the soil, and drops seed directly where it cuts.
After seed is spread, it’s important to follow the right lawncare tips to ensure that it germinates and becomes established. Existing grass should be kept neatly mowed to keep it from blocking sunlight to growing seedlings. The lawn should be kept sufficiently watered, as seeds need water to germinate. The best time to set down new seed is in autumn, after summer heat and dehydration damage has run its course.
Lawns can end up looking ratty, thin, and brown after awhile, even with the best of care. If your grass hasn’t been re-seeded in years and is beginning to show it, it may be time to consider either slice seeding or over seeding to help inject some new life into it.
