Exact answer: 24 hours to a few weeks
How long should you wait after a lawn treatment before cutting the grass? You should wait 24 to 48 hours after treatment before mowing. This is because broadleaf weed control takes at least 24 hours to translocate throughout the plant’s vascular system. The herbicide will not be absorbed into the plant if you cut the grass too short.
The significance of mowing
Before we get into the best time to mow after fertilization, let’s look at the advantages of frequent mowing. Mowing is also an important part of lawn upkeep. Mowing your lawn regularly helps to keep it strong and healthy.
Mowing your lawn regularly also improves its appearance. If you don’t mow your lawn for an extended period, you will notice that it grows at different heights and has a rough appearance.
On the other side, cutting your grass too short makes it more vulnerable to weed invasion, heat damage, and drought. Keeping the grass-fed and vigorous is made easier by mowing. It promotes even growth and height of the grass. Regular grass mowing also aids in the control of pests.
However, to reap the benefits of a regularly manicured lawn, you must know when and how to mow. In the following part, we’ll talk about when to mow the lawn after you’ve fertilized it.
When to mow in the days before fertilization
The best time to cut your grass is shortly before you apply fertilizer. This way, your grass will be at its ideal length when fertilized, and you won’t have to break out the mowers for another week. Allowing your lawn to remain untouched for an extended period will allow your soil to absorb all nutrients before your grass length becomes unmanageable.
Another advantage of mowing the lawn shortly before fertilizer is the grass clippings left behind. Leave those clippings on your grass to give it a natural boost. Ultimately, they will decay, releasing additional organic nutrients and water into your soil.
What’s not to like about an extra vitamin boost? And you don’t even have to pay for an additional fertilizer application!
How long can I mow after lawn treatment?
Mowing your lawn after chemically treating it can be challenging for a first-time lawn owner. The best time to mow your lawn will depend on several factors, including the height of the grass, the type of treatment you choose, the state of your lawn before treatment, and so on.
Experts believe the grass treatment employed is the most important aspect in establishing the proper mowing time. If you choose a standard aeration treatment, you can return to mowing after 24 hours.
If you have weeds on your lawn, you must wait at least 2 to 3 days before mowing it. Herbicides must be applied for at least 72 hours to be effective. If this time range is not closely adhered to, the treatment will be less successful.
Additionally, if fungicide treatments are employed, it is preferable to avoid mowing the lawn for at least 4 days. After the first four days, you can resume mowing the lawn grass. If a scarification treatment is employed, the lawn must be left alone for a few weeks.
The length of the grass on your lawn will also influence when you should mow it. If the grass was recently mowed before the treatment, you could avoid trimming it again right after the treatment. If the grass needs to be trimmed because it has grown too long, it is recommended to follow the treatment instructions and decide the best time to do it.
|Kind of Treatment Used||Waiting Period|
|Aeration Treatment||24 hours|
|Herbicide Treatment||72 hours|
|Fungicide Treatment||4 days|
|Scarification Treatment||A few weeks|
Why should you wait so long after lawn treatment to mow?
Lawn owners must wait a specific amount of time after any lawn treatment before mowing their lawns because the chemicals in the treatment require some time to operate efficiently. They will produce poor results if they are not given adequate time to work.
Herbicides require a 72-hour window to translocate the weed from the vascular system of the lawn when applied to a weed-infested lawn. If the grass is cut or trimmed too quickly, the herbicide will not have enough time to infiltrate the plant and efficiently destroy the infamous weed growths.
Fungicide treatments function similarly. You must allow the chemical to infiltrate the grass to eradicate fungal growths from your lawn. Fungal growths can harm the health and appearance of your lawn. In this sense, it is important to follow the time protocol set.
Aeration treatments do not require chemicals and are typically employed on weed-free lawns. This is merely a mechanical method of aerating the soil by digging holes. As a result, the grass is unaffected and can be mowed shortly after treatment.
Scarification, on the other hand, is a surgical procedure. It aids in reducing thatch, which serves as breeding habitat for moss. It removes moss growths from your lawn. As a result, after this invasive treatment, your grass will not require cutting for several weeks. The best way to care for your grass is to strictly adhere to the mowing schedule specified in conjunction with any particular treatment.
Tips to follow when it’s finally time to mow
After your fertilization treatment, it’s time to resume normal lawn activity! Before you grab your lawnmower, here are the most crucial mowing guidelines to remember:
- Do not mow your grass if it is wet. Water could be dragging down your grass blades, causing an uneven cut.
- Check the sharpness of your mower blades. Mowing your lawn with dull blades will shred it rather than cut it cleanly. This not only gives your grass a ragged appearance but also increases the likelihood of insect infestation or lawn disease.
- Avoid cutting your grass blades too short. You should never cut more than one-third of the top of your grass blades in a single mowing session. Cutting too deeply into the blade can impair your grass’s capacity to produce photosynthesis, making it exceedingly fragile and susceptible to disease.
Mowing after fertilizing is the best way to go.
Fertilizers are typically administered in the spring, early summer, and fall. A different mowing method is required for the two types of fertilizers. If you use a liquid fertilizer, you must wait four hours or until the grass is dry before you begin mowing. If you use granular fertilizer, you should wait 24 to 48 hours before applying it.
Before mowing the lawn, always apply fertilizer and allow it to dry completely. Use a sharp blade, and don’t wait more than a week after fertilizing. You should not use a grass catcher. It may pick up the fertilizer.
Mowing tips following fertilization
- Don’t wait too long: The grass will grow out of control if you wait more than a week after fertilizing. Because most lawn grasses do not acclimatize well when you cut more than one-third of the blade’s length in a single mowing session, the increased nutrients boost the grass’s growing potential.
- Avoid mowing wet grass: Avoid mowing the lawn when damp. Mowing a muddy or wet lawn will damage the grass.
- Watering: Always wash the fertilizer and allow the grass to dry completely before mowing.
- Regular mowing: Don’t put off mowing your grass for too long. Mow regularly, cutting only one-third of the blade each time.
- Clippings: If you mow regularly, there is no need to bag the clippings because short clippings are an excellent natural lawn fertilizer.
- Short grass: Try not to mow the grass too short. Short grass has shallow roots, making it vulnerable to harsh weather conditions.
- Drought conditions: During dry summer weather, raise your blade to the upper cutting range to alleviate stress on your grass.
- Change the mowing pattern: Alter your lawn mowing pattern every time you mow it.
- Sharp blade: When mowing the lawn, use a sharp blade.
Any lawn owner understands the need to use proper lawn treatments to eliminate weeds and promote grass growth. Taking care of a lawn necessitates a significant amount of effort. New lawn owners are generally perplexed about when to mow their lawns following a treatment.
The chemical makeup of a specific treatment influences the best time to mow the lawn following it. Most weed-control treatments allow the lawn to be mowed within 2 to 3 days of the process. However, if the treatment involves scarification, the grass may need to be left alone for a few weeks.
