Can Lawn Fertilizer And Other Treatments Make You Or Your Pets Sick

A number of chemicals in lawn-care products have come under scrutiny in recent years over their potential health impactsparticularly the herbicides glyphosate and 2,4-Dichlorophenoxyacetic acid . Exposure can occur via ingestion, inhalation, or skin contact. And according to the U.S. Centers for Disease Control and Prevention , exposure to large amounts of one or both of the chemicals can result in adverse effects ranging from nausea and vomiting to respiratory issues.

Glyphosate is the main active ingredient in Roundup, which is one of the most widely used weed killers in the world. While the U.S. Environmental Protection Agency foundno evidence that glyphosate causes cancer in humans when it reviewed the available data in a 2020 report, the World Health Organizations International Agency for Research on Cancer classifies the compound as probably carcinogenic to humans. One 2019 meta-analysis of studies on the topic found that exposure to glyphosate was associated with an increased risk of Non-Hodgkin lymphoma, a type of blood cancer, in humans.

Sass adds that there is also concern over organophosphate insecticides, such as chlorpyrifos and malathion, which can damage nerves and cause headaches, sweating, nausea, and muscle tremors. Kind of like having a panic attack, she says. For a pet, they can be lethal.

Best Practices For Fertilizing

Once the grass is established, you can fertilize it following these guidelines:

  • If the soil pH is lower than 4.5, use a fertilizer that contains sulfur. Follow the directions on the label for application rates.
  • For healthy turf and improved color, apply iron supplements in spring and fall.
  • Use nitrogen-based fertilizers sparingly. These fertilizers tend to encourage excess growth of foliage at the expense of root development, which makes grass more susceptible to drought and disease.
  • Apply fertilizers in early spring and late summer or fall when grass is actively growing.
  • Avoid fertilizing before heavy rain, which can wash away the fertilizer before it has a chance to be absorbed by the roots.
  • Apply organic matter to your lawn as needed. This will help improve drainage and reduce compaction. It will also encourage deeper root growth, which is important for drought tolerance.
  • Mulch leaves in the fall to provide nutrients for the grass and help prevent thatch buildup.
  • Aerate compacted soils to encourage deep root growth and reduce thatch accumulation. Aeration also helps water and nutrients penetrate the soil more easily.

    Time Of Year To Apply Fertilizer

    The correct time for you to be applying lawn fertilizer can depend, in part, on the type of grass you grow. People in the northern United States generally grow cool-season grasses, while those living in the South generally grow warm-season grasses. For both types, growers often apply lawn fertilizers in late spring and in late summer. But for cool-season grasses, a third application is often made in late fall.

    Your most important feeding for a cool-season grass may well be the one in late fall. This “winterizing” feeding does more than just prepare your lawn for winter: The nutrients supplied will get the lawn off to a good start the next year, in early spring.

    When To Apply Fertilizer

    The timing and frequency of the fertilization depend upon the types of grass you have in your yard. Generally, we have two types of grass warm and cool-season grasses. Let us check when these common types of grass need fertilizer.

    • Warm-Season Grasses These are often found in the southern states, and it is mostly considered during the summer season. The subtypes of these grass include Zoysiagrass, Carpetgrass, Bermudagrass and St. Augustine grass. When it comes to finding the right moment to fertilize them, it all starts during the late spring season when the grass turns lush green. You can even fertilize the grass during the summer season. However, you should avoid fertilizing during the fall season. Fertilizing it too late in the year can make the grass weak during the winter when the grass is dormant.
    • Cool-Season Grasses These grasses, including bentgrass, ryegrass, fescue grass and Kentucky bluegrass, grow primarily during the spring season. Hence you have the option to fertilize when the grass is actively growing and especially when you intend to mow it. When you see the temperature dropping during the fall season, it is always a good idea to wait till the first week of May and then fertilize these grasses. Choosing this time will reduce the risk of grass burns due chemical use. However, you should fertilize it for around six weeks before the winter season. Carrying out the fertilization late during the fall can weaken the lawn.

    What Can I Do To Make My Lawn Care Healthier

    One guaranteed way to reduce the risk and impact of lawn care is to have less lawn in the first place. That may mean replacing swaths of grass with native plants, or designing landscapes that limit the need for irrigation . Even leaving your grass a bit longer can help, Sass says, If you do less work, the longer lawn will choke out the weeds.

    But if you are set on buying lawn-care products to maintain your yard, Ryan Anderson, the community integrated pest management manager with the non-profit Integrated Pest Management Institute of North America, recommends avoiding products with glyphosate, 2,4-D, organophosphates, and neonics. He also says that people buying fertilizer sometimes dont realize that there may be herbicides already mixed in, such as with so-called weed and feed blendsso double check before leaving the store. There are also some lower risk products, such as Fiesta, that he points people to if they insist on applying weed or pest controlthough he warns that they can be expensive.

    Sass also suggests that unless someone is a particularly experienced gardener, they can avoid unnecessary complications or accidents by staying away from products that they have to mix themselves from a concentrate. I hope they are buying those products that are ready-mixed, she says. She also adds that, instead of putting mosquito treatments on lawns, people could consider using bug repellent.

    How To Fertilise A Lawn

    You can fertilise a lawn by hand, but it can be a difficult process as it is hard to tell whether you have put the right amount down. It is generally advisable to use a spreader as most lawn care professionals do because they can help you to spread your fertiliser evenly over the surface and give better results. There are several different types of spreader that you can use. Shoulder or handheld spreaders are good for gardens that are not a standard rectangle shape and are very easy to use. You can also use mechanical push-along spreaders. These spreaders are better for large gardens where you have a lot of fertiliser to spread. Rotary spreaders have a spinning mechanism that throws or sprays the fertiliser while drop fertilisers have small holes in the underside out of which the feed drops onto the grass. Liquid fertiliser can be sprayed directly onto the lawn surface and is good for demand feeding in areas that need more nutrients.

    Ideally you should feed your lawn as soon after mowing as possible as this will give the grass more time to absorb the nutrients before the next mow. If you mow your lawn after fertilising you may remove the fertiliser before it has a chance to sink in properly.
