Why You Might Want to Keep Your Clover

But, before we talk about How to Eliminate Clover without using chemicals, let's spend a second looking at the benefits of clover and perhaps convince you that you'd like to keep the clover after all.

Reason 1: Clover Fertilizes Your Lawn

Clover has a symbiotic relationship with bacteria that attach themselves to its roots.  These bacteria can absorb nitrogen (the main nutrient that gives grass its green color) from the atmosphere, meaning that it doesn't need to be fertilized.  Even better, if you have a good mix of clover (or microclover) you shouldn't need to fertilize your lawn much.  Contrary to poplular belief, clover won't take over your lawn, it will help your lawn.  Notice how the side of the soccer field below that is planted with microclover is greener than the side to the right - clover can keep your lawn greener with less fertilizer!

Reason 2: Clover Prevents Weeds

We talk about mowing your lawn high to help prevent weeds.  Mowing High helps prevent weeds because the taller the grass, the more it shades the surface of the soil and makes it difficult for weeds to establish.  Clover, with its umbrella like leaves, shades the soil better than blades of grass do, so it shades the soil very well.  If you have clover in your lawn, you can even mow at a more normal mowing height (2.5 inches).  So, if you like mowing your lawn short, clover can help you avoid having a million other weeds.  See how the section of grass that has microclover in it below has far fewer dandelions than the non clover section?

Reason 3: Microclover Provides Clover Benefits without Drawbacks

Over the years many people have called us wondering how to eliminate the clover in their lawns without using chemicals.  Once they understand the benefits of clover they're often to leave the clover and even consider purchasing additional microclover to help make the lawn more uniformily clover covered!

The image above is of a lawn seeded with our Microclover which flowers much less prolifically than standard white clover and is aggressive enough to spread evenly through a lawn.  We've found that lawns planted with microclover stay greener, healthier, and have fewer weeds than lawns with no clover.  In addition, they need less fertilizer and water.  So, if you have convinced yourself that if you can't "beat clover, join clover" then you might want to learn a little more about microclover by visiting our website at www.whygoodnature.com/microclover or purchasing it in our online store by visiting store.whygoodnature.com/microgreen-microclover.

How to Eliminate Clover Without Chemicals

Ok, if you're still determined to eliminate clover that's no problem, let's do it with out chemicals!

Step 1: Fertilize Your Lawn

Clover thrives in underfertilized grass because it has the advantage - it can make its own fertilizer and grass really can't.  So, if you fertilize your grass with a good organic fertilizer in the spring and fall then you will give the grass the advantage.

Step 2: Mow High

Clover has no problem being mowed nice and short, but your grasses don't love it.  When you cut your lawn under 3 inches tall, the clover will appreciate it and the grass will get a little stressed.  So, mow high to give your grass an advantage over the clover.

Step 3: Kill the Clover - Organically

There is an exciting new organic weed killer on the market for killing weeds in your lawn without killing the grass.  If you spray this new organic weed killer (Adios) on the clover in the grass, it will weaken the clover without harming the grass and give your grass the advantage it needs to outcompete the clover.  Adios is the product and I've had some great success with it killing clover in our trials.

Step 4: Water Properly

If you're going to use Adios to kill the clover in your lawn without chemicals, you should keep your lawn properly watered.  It's best if you can water deeply (1 inch - enough to fill a tuna can) once or twice per week.  The day after one of those deep waterings when the grass is not stressed out, you can apply adios to kill the weeds in your lawn without killing the grass.  If you spray the Adios on a lawn that isn't getting water and is stressed out by heat and drought, you may end up killing your grass as well.  So, before you spray Adios to kill the weeds in your lawn organically, make sure you're keeping your lawn well watered.

Final Note

The Clover we're referring to is White Clover, a perennial weed.  There are other annual weeds that people often call Yellow Clover - typically Black Medic, and Oxalis get called Yellow Clover.  You can use Adios to kill these "yellow clover" plants as well but don't need to because they are annuals and will die at the end of the season anyway.  The best way to fight the yellow clovers is by using organic fertilizers, mowing high, and watering properly.

How To Stop Animals From Digging Up The Lawn

September 10, 2018 by Alec McClennan

There are a variety of critters who sometimes frequent our lawns and can cause issues while theyre looking for food. Moles tunnel under the ground and can create a mess, especially in the Spring. Skunks and Racoons are more of an issue in the Fall as they work to fatten up for winter. Why are Animals Digging In My Lawn? Animals will dig because theyre hungry. Moles, Skunks, and Racoons all eat a variety of worms, insects, and grubs. Just because you have Animals Digging, it does not mean that you have a grub problem. Animals will dig in search of food and return to places where theyve found food in the past. How Many Grubs is too Many? A healthy lawn can tolerate up to 5 grubs per square foot. An average size lawn is 5000 square feet, so that is 25,000 grubs! Its not possible to kill all the grubs, even if you resort to using a chemical that sits on the lawn for months. Using a natural grub suppression treatment like beneficial nematodes is a good idea to minimize one of the food sources

Urban Pesticide Use and Water Quality

July 03, 2018 by Danielle Kohan

Conventional lawn maintenance includes regular use of synthetic lawn chemicals, such as fertilizers and pesticides, which are typically applied repeatedly throughout the season. After every application a portion of the chemical is taken up by the soil and plants, but the remainder may be washed away during rainstorms where it can make its way into streams and lakes. This type of pollution is known as runoff. There is already clear evidence that links runoff from roads and farms to pollution in rivers and lakes, but, more recently, research indicates that the contribution from urban lawns is also significant. These chemicals dont discriminate they act as fertilizers and pesticides wherever they go. Nutrient pollution from fertilizer is essentially a too much of a good thing type of problem. In lawns and on farms they are intended to help grow desired plants, but when this fertilizer reaches a lake it spurs the growth of aquatic plants and algae and may have negative effects. For example,

Starting Your Family's First Compost Project

April 09, 2018 by Maureen Wise

If your family is looking to reduce the weight of the trash can you pull to the curb every week, composting your organic waste could cut your landfill trash by up to 30%, according to the US EPA. By composting your kitchen scraps and garden waste instead of landfilling, youll also help reduce greenhouse gases produced by landfills and end up with a locally made plant fertilizer (local, as in your own backyard!). We like natural fertilizer here at Good Nature Organic Lawn Care and are here to help you with some steps to start your familys first compost project. Choosing Your Location There are lots of options of where to let your compost decompose. Ideally, you need a spot where the compost will get a bit wet but not saturated so under a tree or behind a shed are optimal spots. Youll also need to have your compost contained in some way. A rotating drum is a popular alternative. These models often have wheels which makes for easy dispersal of compost when ready but they can be on the pricier
