What is organic lawn management?
Organic lawn management should be viewed as a ground-up approach to lawn care. This means that you start with the soil and the roots before worrying about treating the plants. Transitioning from chemical lawn care to organic is a change in perspective, routine, and lifestyle. The goal is not to be weed or pest free, but to learn what detritus and bugs are beneficial for plant growth and how to naturally deter or manually remove what is not. Organic lawn care is intended for the residential community who seeks to maintain healthy lawns without damaging the environment or exposing others to health risks connected to synthetic chemicals. This method means maintaining grass and the rest of your landscape without the use of synthetic fertilizers, pesticides, insecticides, or herbicides. Organic lawn care systems also use naturally occurring and non-toxic additives to create a healthy soil ecosystem, which is the foundation for a strong lawn and garden. Organic lawn care requires much more time and manual labor because instead of spraying pesticides and herbicides, the grower removes unwanted material by hand or uses more gentle natural pesticides and herbicides such as vinegar or soap-and-alcohol based sprays. The Oxford English Dictionary defines “organic” as it relates to lawn care, as a “method of farming or gardening: using no chemical fertilizers, pesticides, or other artificial chemicals” (Oxford English Dictionary, n.d.). By this definition, organic lawn care is maintaining a lawn or greenspace through purely natural methods and using no synthetic inputs.

Due to increasing awareness about the health risks of POPs, or persistent organic pollutants, more people are choosing to stop using synthetic chemicals in farming and gardening. (China Chemical Reporter, 2009, p. 27). Synthetic fertilizers, pesticides, and herbicides runoff from lawns into stormwater and can pollute bodies of water. According to a 2009 article published in the journal China Chemical Reporter, the 2001 Stockholm Convention was an international agreement among countries to take steps to ban POPs, or persistent organic pollutants. China was among these countries and announced a ban against the “trade, use, and import and export” of POPs such as DDT, mirex and hexachlorobenzene. In addition, China set a goal for managing and treating POP wastes (China Chemical Reporter, 2009, p. 27). According to Hirsch & Baxter (2009), some residents continue to choose pesticides in lawn care to maintain the standard and conventional suburban lawn look, despite being aware of health and environmental risks they know are caused by pesticides (pp.468-490). Hirsch & Baxter (2009) establishes that pesticide-free policies and programs are not entirely effective since people continue to seek weed-free lawns and neighborhoods and are unaware of the organic alternatives (pp.468-490). Hirsch & Baxter (2009) studied the social pressures that influence people’s decision to continue using herbicides and pesticides despite knowing the associated risks (pp. 468-490).

Meyer (1995) provides a step-by-step guide to maintaining a turf grass lawn organically, without chemical fertilizers or pesticides or herbicides (p. 46). As mentioned in the introduction, the goal of organic lawn management and organic growing in general is not to be completely insect free, but some insects do pose a threat to plants and need to be removed. Luckily, there are ways to do this without resorting to chemical insecticides that can end up in the water supply. There are important things to consider if you are considering switching from synthetic to organic lawn care. According to Robinson (2019), organic lawn care focuses on the soil, rather than on the grass. This approach nurtures a balanced pH and reduces soil compaction so that a healthy lawn can grow without the need for pesticides, herbicides, and fertilizers. If the turf grass is growing in unhealthy soil, it will become nutrient deficient and opportunistic weeds will grow in its place. If the soil is too compacted, meaning there are too few or too small air holes, water and air will not be able to reach the plant roots and deliver nutrients (Meyer, 1995, p. 46). "You should start by getting a soil test," suggests Arthur Bruneau, Ph.D., professor of crop science at North Carolina State University in Raleigh. "You'll want to find out the soil's pH and if it has any deficiencies, especially of calcium and magnesium" (Meyer, S., 1995, Para. 3). The next step after determining the quality or lack thereof of your soil is to make changes to it with naturally occurring additives. According to Meyer (1995), the preferred pH range of turf grass is between 5.5-6.5 and “mined rock powders” such as dolomitic limestone, calcitic limestone, and gypsum are substances that can be added to balance the pH and comply with most organic growing standards (p. 46).

Robison (2019) stresses the need for patience and a completely new mindset to be successful in organic lawn management. Transitioning the subsurface from synthetic to organic management will be beneficial and lower maintenance in the long-term but takes a lot of attention at first. Robison (2019) recommends finding sources relevant to your specific climate zone. Next, the author explains that “natural organic fertilizers are water-insoluble,” so they take longer to break down than synthetic chemical fertilizers (Meyer, 1995). However, this also means that they last longer and only need to be applied every few months instead of every month. Next, the author discusses the necessity of the three basic components of organic fertilizers, which as Nitrogen, Phosphorous, and Potassium. According to the author, different types of grasses have different N-P-K requirements, so it is important for growers to find the optimal balance of N-P-K. The author goes on to explain how organic fertilizers derive nitrogen, which apparently is usually in the form of animal by-products such as poultry waste. Large fertilizer companies (ex: Chemlawn) have traditionally provided chemical fertilizers for sale but are now offering alternative fertilizers as an option for those who are looking to switch to organic lawn care. Chemlawn, for instance, is offering an organic fertilizer made from “dried poultry waste” (Poncavage et al., 1991, p. 14). However, it is important to read the ingredients of fertilizers because technically any substance containing carbon can be labeled as organic, even if it is synthetically derived and potentially hazardous to the environment. That is why it is important to read the ingredients and check to see if it is derived from a natural source, not synthetically from sources like urea, “a manufactured product that mimics animal urine” (Meyer, 1995). Lastly, the author suggests that the best organic fertilizing technique you can use to improve your lawn health and appearance is leaving grass clippings on your lawn instead of raking them up. According to the Meyer (1995), at the “Rodale Institute Research Center, the researchers have analyzed grass clippings and found that an acre's worth of clips will furnish an average of 235 pounds of nitrogen, 77 pounds of phosphorus and 210 pounds of potassium to a lawn each season”.

If one is especially concerned with environmental risk factors of maintaining a turf grass lawn (i.e. water consumption, nitrogen run-off causing algal blooms, lack of food for pollinators), they might opt to replace the traditional lawn with an attractive alternative. Lawn alternatives can be anything from a native plant meadow to a gravel hardscape, depending on their specific region and property. Lawn alternatives can provide a variety of ecosystem services such as pollinator hosts and increased permeability for frequently flooded areas. Unlike turf grass, lawn alternatives do not require frequent maintenance and fertilizing. However, they do require their own type of upkeep even if it does not depend on synthetic chemicals and they should not be viewed as a no-maintainence but rather a low-maintanence and environmentally friendly alternative. If one opts to maintain an organic lawn or garden, they should keep in mind that it is not just about what chemicals and additives you eliminate from your treatment options, but even more importantly it is about what materials you do add. Plants that are cultivated in residential areas require nutrient additives, but it is important to use natural products that break down and to only use enough that the plants can use, because otherwise you can cause dangerous ecosystem imbalances that harm waterways and aquatic life.
