Once the leaves fall from their trees, a new chore can be added to the list – leaf raking! This can be back-breaking work if done by hand. According to the U.S. Environmental Protection Agency in 2017, leaves and other yard debris account for more than 13 percent of the nation’s solid waste—a whopping 35 million tons a year! Creatively and judiciously managing leaves by mulch mowing can save time and money in your fertilization effort, save your back, and keep leaves out of the landfill. Here are some simple guidelines and strategies to help you mulch mow your leaves.
Mulch mowing is just what it sounds like - chopping leaves into small pieces until it turns into a mulch like material that is returned to the lawn. Leaf debris naturally composts, allowing nutrients to return to the soil. Successfully mulching leaves into the lawn requires frequent mowing in the fall and possibly several passes during one mowing session. It is important to chop leaves adequately until they’re about the size of a dime so the leaf debris breaks down quickly. Specialized mulching mowers are available, and these mower types will also be beneficial year-round to mulch grass leaves into the lawn. According to K-State Extension, “mowing during the leaf season is not based on grass growth but on the rate at which leaves fall and collect on the lawn. Mow a thin layer, approximately 1” each time. This thin layer is chopped by the mower and then filters through the leaf blades where it works its way down to the soil.” Research has shown that a total of six inches of leaves can be successfully shredded and composted into the lawn and thus returned to the soil without causing damage. If you determine that your trees deliver more than 6 inches of leaves, it is best to mulch mow then bag. This can be done by first mowing without a bag and then mowing a second time with a bag in place. The second pass will enable leaves to be sucked up into the bag and take-up considerably less space thus allowing you to decrease the volume of leaves two to four-fold. The chopped leaves can be used as mulch for flower gardens and trees to help conserve moisture. Just remember not to use more than 2-3” of mulch around plants and steer clear of the crowns of plants to deter voles and rot. The leftover leaves can also be used in the compost pile. Another reason to utilize leaves in your landscape, according to the National Wildlife Federation, is that “Removing leaves also eliminates vital wildlife habitat. Critters ranging from turtles and toads to birds, mammals and invertebrates rely on leaf litter for food, shelter and nesting material. Many moth and butterfly caterpillars overwinter in fallen leaves before emerging in spring.” Leaves should not be dumped into local streams as the extra organic matter can lead to excessive nutrients into our bodies of water thus causing potential algae issues and lower water quality. Leaves that are left on the street can also clog storm drains which can result in flooding.

Products in our homes and garages that are flammable, toxic, corrosive, or reactive are considered household hazardous waste. Products such as pesticides, paints, pool chemicals, CFL light bulbs, cleaners, oils, automotive fluids, thinners/strippers, acids/bases, and batteries require special care when disposing of them and can catch fire, react, or explode under certain circumstances.
Why is household hazardous waste a problem? Household hazardous waste poses many dangers ranging from personal exposure to the substances during use, to contamination of water resources from improper disposal of chemicals down a storm drain or into a ditch, where they can be transported directly to bodies of water. According to the Environmental Protection Agency, the average home can accumulate as much as 100 pounds of hazardous waste! That’s 100 pounds of household chemicals with labels that say: poison, corrosive, toxic, flammable, or keep out of reach of children/pets, in your home. Paint is one of the most common household wastes and can be the most confusing to deal with. First, read the label and identify whether the paint or stain is water-based or oil-based. Water-based products can be disposed of in your regular trash, but must be hardened first using kitty litter or other paint hardening product. Be sure to leave the lid off the can so your waste hauler can confirm the product is dry or else they may refuse to collect it. If the product is oil-based it is considered a hazardous waste and should be taken to hazardous waste center where it will be properly recycled or disposed. Warren County has a latex paint only recycling drop-off location in Lebanon. This is open weekdays and is for Warren County residents only. Questions regarding the drop-off site should be directed to the Warren County Solid Waste Management District, 513-695-1209. What should you do with household hazardous waste if you have it or plan on using it?

In the last few years we have experienced record rainfall events. While rainfall (otherwise known as stormwater) is a natural occurrence, unfortunately our environment is not always in a “natural” state. In other words, we have developed areas such as roads, sidewalks, roof tops, parking lots and other impervious surfaces where stormwater does not have a chance to soak down into our soil. This stormwater becomes runoff and picks up pollutants from our lawns and streets (examples - vehicle emissions, oil residue, grass clippings, pesticides, leaves, and pet waste) and enters our lakes and streams by way of storm drains thus causing water pollution and impairments within our local bodies of water. Stormwater runoff is the number one threat to our water quality according to the U.S. Environmental Protection Agency. How can we help? Below are some simple management ideas that could be implemented within the landscape to help store and clean some of this stormwater thus lessening the amount of water entering our stormwater sewer systems. Utilizing Rain Barrels Rain barrels connect to downspouts to collect rain water. The collected water can then be used to water gardens, and be used as grey water for washing outdoor items. Water collected from rain barrels is not for human consumption, however. Some of the other benefits of rain barrels include:
Creating a Rain Garden Rain gardens are a unique feature that can be added to the landscape and is disguised as a flower garden. They have many benefits that include: providing wildlife habitat, providing nectar and pollen sources for pollinators, transforming rainfall runoff into a resource rather than a nuisance, and improving storm water quality as it is infiltrated and redistributed through soils. Rain gardens are purposefully located to maximize the amount of stormwater runoff that flows into the garden rather than off the property. It is important to note that it is not just a garden bed. Garden size, depth, slope, soil amendments and drainage all need to be considered before putting a shovel into the ground. Plants that thrive in your landscape and in southwest Ohio should be considered. Native plants are good choices because they tend to offer more benefits to pollinators and have better survivability in native soils. To help prepare your rain garden’s site, check out the following resources:
Before putting any of these water management strategies into place, please check local ordinances to make sure you understand what is allowable.

By targeting several management strategies, lawn care can become more environmentally friendly and help keep our water clean. Leave the clippings on your lawn. Over time the action of mowing and taking away the clippings can deplete the soil of valuable nutrients. Leaving the clippings returns these nutrients to the soil and can promote less fertilizer usage over time. Mow high. Adjust your lawn mower to mow in the 3 to 4 inch range. In general, grass should be in the 4 to 4.5 range at its longest. The health of the grass significantly increases when you can leave more green growth on the plant. Healthier grass means that your lawn will have less instances of disease, insect and weed issues. Keep your lawn mower blades sharp. This ensures that you are not tearing/shredding the blades of grass. Continuously tearing and/or shredding the plant can hurt the crown of the plant and ultimately kill the grass. Check at your local hardware store as to who in your local area can sharpen your blades. Fertilize in the fall. Fertilizer applications should always be based on a soil test. Fertilizing without a soil test can easily lead to over-applying fertilizer, which can cause problems for our environment such as algae blooms in our local waterways. If you choose to fertilize, a late fall application in September and then in mid to late October is the best time. Adding a fertilizer application again in mid- to late May helps keep the lawn green and healthy throughout the summer. Do not add fertilizer during or right before an expected rain event as that is throwing money away, and adding nutrient pollution to local waterways. Consider letting the grass go dormant in a dry summer. If the summer is dry, you may decide to save water and not irrigate your lawn. If you choose this option, the grass will go dormant and turn brown. Don’t worry, the grass is not dead. It will revive when cooler weather and rain come back in the fall. Grass generally does not die until you have 4-6 weeks of very dry weather. Choosing to water is your personal decision but know that you should water deeply and infrequently rather that quickly and often. As a general rule apply a half-inch of water every four weeks after the lawn turns brown. Also, it is important to minimize traffic on a dormant lawn to reduce possible damage. Rethink your lawn. Did you know that we can thank pollinators for 1 in 3 bites of our food? Unfortunately, grass does not offer the nectar or pollen sources that pollinators need to survive. Consider turning part of your landscape into a pollinator garden or admiring the beauty that clover, violets and dandelions provide in a sea of green. It is important to do your research on local ordinances especially if you choose to make your yard a “pollinator lawn”.

Did you know that bees are responsible for one in three bites of food that we eat! Bees give us honey but in the process of foraging for nectar and pollen they also help us pollinate important food crops such as apples, peaches, tomatoes, cucumbers and almonds. The honey industry is a direct contributor to the success of American agriculture. Today, the honey industry faces many challenges, such as hive loss, drought, colony collapse and shrinking forage areas. What can you do to promote more bees in your area? Why not plant a bee-friendly garden! Here are some tips from the Honeybee Conservancy and The Ohio State University Bee Lab to help you plan for your pollinator garden:
