I have noticed a few signs of aeration and overseeding advertising. It’s almost March now and those lawn aeration, overseeding and pre-emergent advertisements catch my attention. But there are a couple of things to consider.
First, overseeding should be done in the fall. However, due to last season’s dry spell, many non-irrigated lawns were too dry to core aerate. Many lawns are now in poor shape with bare spots and weeds which hardly need lawn care aeration.
Here’s the caveat, starting around February most will spread their first pre-emergent/fertilizer application. (Crabgrass starts to germinate when the ground temperature reaches around 55°F for three consecutive days).
This pre-emergent creates a barrier just above the soil to prevent crabgrass and other weeds from germination. When your core aerated that barrier is now compromised. Which defeats the purpose of putting it down. Furthermore, if you overseed the pre-emergent will inhibit the new grass seed from germinating. The pre-emergent will kill the new grass.
New grass needs time to get established. That’s why fall is a great time to overseed. It should give the new grass enough time to germinate, grow, get mowed before a hard frost, go dormant over winter, and start growing again come spring. All this is what should be a cooler time of year. When new grass is sowed in the spring. It is most likely going to be subjected to the heat and dry conditions of the summer months. This will stress the new grass and it may or may not survive the season? Mostly due to its root system not being deep enough yet.
What Is Aeration?
You might already have an idea of what lawn aeration is.
So basically, Lawn Aeration is creating holes in the soil to loosen it and help lawn grasses grow. Lawn aeration improves the overall quality of your lawn.
Lawn aeration has three basic uses; controlling lawn thatch, reducing soil compaction,and making grassroots multiply. But the main reason why we want to aerate our lawn is to alleviate soil compaction. Compacted soils have too many solid particles that avert the circulation of air, water, and nutrients underground.
On the other hand, there is a core aeration. Core aeration is a type of lawn aeration that mechanically removes plugs of the soil with the use of a core aerator.
Aerators are garden tools designed to dig holes and perform aeration. There are two basic types of machine aerators:
- Spike Aerators – Uses solid spikes to dig holes in the soil.
- Core Aerators – Uses hollow tines that pull out plugs or what they call “cores” from the soil and leaves the core on the turf.
If you want to be hands-on and practical, you can use manual aerators. Manual aerators usually have two to five hollow tines mounted on a step bar.
Tips for Lawn Aeration
It would be best if you conduct simple lawn care and maintenance to achieve and preserve a beautiful garden. It is also necessary to ensure that under your grass, nutrients enter the soil. Aeration can be an incredibly important aspect of a safe paddling pond because air and water enter built-in grass or spawning stalk.
You can either power tools to aerate your lawn or do it manually. Here are the best lawn aeration tips.
Tip #1: Use aeration machines with hollow metal tines.
Peiffer says the best aerating machines are those with hollow, metal tines that penetrate the ground and pull plugs of soil from the lawn. You can help the tines penetrate deeper by watering your lawn one to two days before aerating.
Tip #2: Lawn aeration should be done at least once a year.
Ideally, Lawn aeration should be done at least twice or more a year. But if it is too time-consuming for you, we suggest doing it at least once a year. Lawn aeration can help ensure your lawn systems and bring back its vivid green grass.
Tip #3: Aerate your lawn with caution.
We use several types of tools to aerate our soil. We can use a pitchfork when performing manual aerating or use big mechanical aerators. You can use marker flags to mark your irrigation heads to avoid massive damage by aeration.
What Is Overseeding?
Overseeding is the seed planting in established turf directly, without cutting down the turf or the soil. It is an easy way to fill up bare spots, increase the grass’s density, grow better herbal varieties, and improve your lawn color.
Overseeding is spreading grass seeds over your loan. When you’ve done aeration and overseeding right, you’ll get fantastic results.
Tips for Lawn Overseeding
After Lawn Aeration, Overseeding is a vital process we cannot skip. Because in overseeding, we plant grass on our lawns and hope to reach our goals to have a rich beautiful green grass field.
Tip #1: Always Prepare Your Lawn Beforehand
You can’t just overseed with your untouched lawn.Your dry soil might not penetrate your grass seeds. Always aerate before overseeding and pre-emergent. Set your mower at two inches or less for regular overseeding. Always loosen and expose your soil before overseeding.
Tip #2: Choose a quality grass seed
Believe it or not, there are super cheap seeds you can avail online but won’t ever grow. High-quality seeds make your lawns a lot better. Know what kind of grasses recommended for your regional climate. Always choose top-quality and tested grass seed brands. Apply quality and premium-grade fertilizer and soil enhancer for best results.
Tip #3: Make sure to spread your seed
Using a lawn spreader might be a big help for you. It saves time and distributes your seeds better than spreading your seeds by hand. Using a lawn spreader is a lot convenient if you have big lawns. For small spots and areas, you can use handheld spreaders. Also, observe the air before throwing seeds. Overseed when the air is calm.
Tip #4: Hydrate your lawn
Keeping your loan hydrated will keep the moisture of the seed. Remember not to over hydrate it. We only need consistent moisture. Keep watering your seeds to develop healthy roots and avoid wilting.
What is Pre-Emergent?
Pre-emergent are usually chemicals that prevent undesired weeds in your lawn. Pre-emergent do not prevent the germination of the seed but it helps control the germination so that it will not sprout. Pre-emergent is an effective weed management program. Timing is very important in application or pre-emergent as it can sometimes be tricky. We must also understand that pre-emergent is not designed to control existing weeds. Once the weed begins to sprout from the seed and hit the herbicide barrier, it will be killed.
Winter/Spring overseeding. Providing you have not applied any pre-emergent to your lawn this season the next consideration is addressing weeds. If you just have a couple of smaller areas of the lawn that need seeding you can simply avoid the application of pre-emergent to those spots while treating the rest. However, if your whole lawn requires repair you’ll be dealing with some weeds. There are many herbicides you can use to address weeds which will come up during the season. However, there is one weed that may prove to be an issue, Dallisgrass. This particular weed is difficult to manage with the given herbicides on the market. In its initial stage, it looks like crabgrass. Yet it quickly produces stocks with seeds. Then when you mow those weed seeds spread. One method, if you don’t have a prolific spread of Dallisgrass, is to simply dig the weed out.
Core aeration and overseeding is a great practice to get your lawn in shape. Understanding when and how to use this method will save you time, frustration, and money.
You can overseed in the spring, although not the ideal time, just beware of the additional work required to get your lawn back in shape. Or just wait till next fall and renovate your lawn then, while working on what you do have established.
