Aeration Plugs2

Let Your Lawn Breathe Again!

October 13, 2017

 Your lawn is crying out for core aeration when the ground becomes compacted due to shade or heavily trafficked areas. Compaction can occur in a variety of places……where children play, on a footpath or in post-construction areas.

Compaction usually causes bare/worn looking patches in the lawn. The ground can feel hard underfoot.
Aeration is done with an aerating machine that removes soil plugs approximately 2-3 inches deep, allowing nutrients, air and water to penetrate down to the grass roots. The machine is hard to manage and is usually best handled by a professional.

The soil should be moist to begin.

Mark the irrigation system so it isn’t punctured.

Directly after aerating, spread seed and compost (or compost tea).

Water well.

The plugs will dry and return to the soil. If you are in a rush, they can be raked in.

The best time for aeration is NOW -- Fall --to get the best root regrowth and seed germination.

Ahh, that felt good!

The PRFCT time

September 30, 2017
Fall is the time for seeding, feeding, and aerating your lawn. Weeds grow in warm weather, grass prefers cool…that means the best time to fix the lawn is… fall, right now.

If there are bare areas in your lawn, reseed now, the grass can fill in and weeds will have no place to grow in the spring! But, don't over seed! Over seeding is the process of spreading seed over an existing lawn to fill in bare patches. How much seed to apply? Depends on the type of seed you are using. Look on the package for recommended rates.
Over seeding occurs when too much seed is applied over a given area. Why isn't more better? Too many grass plants growing too close together leads to over competition and die-off. In humid conditions, it can also cause mold and other fungus diseases like in the picture above. Gross.

For areas that are always a problem, look for the cause.
If compacted: break up or aerate the soil.
Replace or amend poor soil with organic, weed free compost or new soil.
Too much shade? Try a shade tolerant grass or consider a Long Island native ground cover like Pennsylvania sedge and mow it just once a year.
Atrazine molecule

Atrazine is the second most widely used pesticide in the US (after glyphosate), with over 73 million pounds applied each year. A common agricultural pesticide, atrazine also is used on turf for broadleaf and grassy weed control. Because atrazine kills cool-season grasses like Kentucky Bluegrass, it is primarily used on lawns in warmer climates (ie. the Southeastern United States).

In humans, atrazine has been linked to:
• Endocrine disruption (what does this mean, anyway?)
• Cancer
• Birth defects and reproductive disorders
• Neurological effects
• Kidney and liver damage
• Eye and skin irritation

How are people exposed to atrazine? Not just direct contact with treated lawns, fields, and food. Atrazine is found in 94% of drinking water tested by the USDA, usually spiking in spring and summer months when it's most heavily applied. Even at extremely low levels, atrazine can interfere with human hormones, fetal development, and fertility. The European Union banned its use in 2004 over concerns that it is a groundwater contaminant.

What is endocrine disruption?

Your endocrine system is the set of glands and hormones they produce (such as estrogen, testosterone, and adrenaline) that help guide your development, growth, and reproduction. Some chemicals—known as endocrine disruptors—mimic your hormones, block hormone absorption, or otherwise alter the concentration of hormones in your body. Endocrine disrupting chemicals have been linked to ADHD, Parkinson’s disease, Alzheimer’s disease, cancers, diabetes, cardiovascular disease, obesity, early puberty, infertility, and other reproductive disorders.

Entomopathogenic nematodes nematodes under microscope

Maybe you've seen beneficial nematodes for sale at your local organic gardening center. Or heard about nematodes attacking the roots of your neighbor's tomatoes. What's the difference? And what are nematodes, anyway?

Nematodes are round, threadlike organisms that eat organic material—from bad bugs and bacteria to plant roots—in your soil. Like the bacteria in our bodies, soil nematodes can be helpful or harmful, depending on the type and number present. A healthy balance of nematodes is key to the health of your soil's ecosystem.

Good nematodes:
• Break down soil nutrients so that plants can easily absorb them
• Eat pests like grubs, bad bugs, and fungus
• Harmed by synthetic fertilizers and pesticides

Bad nematodes:
• Eat plant roots

Want to make your soil friendly for beneficial nematodes? Make sure it is well-aerated; nematodes need plenty of space to move around. Kicking the chemical habit and adding compost to increase organic matter will help balance your soil's biology. When your soil biology is healthy, the less-desirable nematodes—and other pests—will be kept in check naturally.

Bare feet walking on lawn

What is a 3-, 4-, or 5-step lawn program? A series of products labeled 1-3 (or 4 or 5) that are sold to be applied month-by-month throughout the growing season. They are all-in-one mixes designed to treat a range of typical lawn problems. They usually contain synthetic fertilizer combined with synthetic pesticides—various weedkillers, fungicides and insecticides, depending on the month. Some mixes also contain grass seed.

What’s the problem with multi-step programs? Not only are they packed full of the worst kinds of chemicals, but they are treating your lawn for problems you may not even have. Like going to the doctor and getting medication for every known health condition, just in case.

Multi-step programs offer short-term solutions with long-term consequences. The lawn may green up temporarily, but the fertilizer and chemicals will eventually pickle the soil. Excess nitrogen from the fertilizer can leach into nearby water bodies, contributing to algal blooms. And who wants to walk across a lawn covered with chemicals?
