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).
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!

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.
If compacted: break up or aerate the soil.
Replace or amend poor soil with organic, weed free compost or new soil.
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.
• 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
• 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.

What’s in that magic bottle of liquid sprayed on driveways and sidewalks to kill stubborn weeds? Mostly it’s glyphosate, the active ingredient in Roundup and other weed killers that was deemed a “probable” human carcinogen by the World Health Organization in 2015. Glyphosate also is used widely in agriculture, resulting in weed resistance, water contamination, soil degradation, and damage to marine wildlife. Over 826 million pounds of glyphosate are applied to crops and landscapes across the globe every year.
Some of the scary human health effects associated with glyphosate:
- Non-Hodgkins lymphoma
- Kidney and liver damage
- Endocrine (hormone) disruption
- Reproductive effects
- Eye and skin irritation
Also in these products, but not listed on the label: a host of “inert” ingredients that make the active ingredient easier to apply or better able to adhere to its target. These inerts can be as toxic as the active ingredients themselves and/or amplify the toxicity of individual ingredients when combined. For example, many glyphosate products contain polyethoxylated tallowamine (POEA), a surfactant that is considered more toxic to marine life than glyphosate.

- 1 gallon 20% vinegar
- 1 cup orange oil
Mix vinegar and orange oil in a bucket. Mix thoroughly, and use a spray bottle to apply to all surfaces of plant. Reapply as necessary. Store any unused liquid in a clear, labeled glass container and store in a cool, dark space.
Note: Be sure to wear gloves and protective eyewear when applying your homemade herbicide. It can irritate your skin and eyes.

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?
