Our landscapes are our outdoor homes: fun, beautiful, great spaces for relaxing. By taking care of our land and gardens properly, we can save money, time, and help the environment. GreenScene encompasses a set of landscaping practices that can improve the health and appearance of your landscape and garden while protecting and preserving natural resources.
In nature, soil recycles dead plants into nutrients for new plant growth. Plants are adapted to the water, sun and soil available in their site. Maintaining a wide variety of healthy plants, soil organisms, beneficial insects and animals can keep most pests and diseases in check.
By working with nature, you can have a great-looking yard that's easier to care for, cheaper to maintain and healthier for families, pets, wildlife and the environment.
A teaspoonful of healthy soil contains about 4 billion organisms! This community of beneficial soil creatures keeps our landscapes healthy by:
A soil test will tell you how much nitrogen, phosphorus, potassium and lime your soil needs to grow healthy plants. Depending on the condition of the soil, you may not even need to apply these nutrients! Contact your local garden supply center for a soil test kit.
Dig or rototill one to three inches of compost into 6 to 12 inches of top soil when you're making new beds or planting lawns. Top dress existing lawns with a quarter- to half-inch of compost every spring or fall. Compost helps sandy soils hold nutrients and water, loosens clay soils and feeds the beneficial soil life so it can feed and protect your plants.
Yard and food waste are a gardener's gold! Leaves, chopped stalks, flowers and grass all make great compost in a pile or bin. Vegetable scraps and coffee grounds can also be added to your bin, but do not use meat, dairy or oils because they can attract pests. You should turn your compost every few weeks with a pitchfork to distribute air and moisture. Make sure to sprinkle water on your pile in dry weather. In most climates, you will have finished compost in 3 to 6 months, when the waste becomes a dark, crumbly material that is uniform in texture. You can then spread your compost in garden beds, under shrubs, on your lawn, or use it as potting soil.
Mulch is a layer of organic material like leaves, aged wood chips, compost or grass clippings that you spread in spring or fall around your plants. Never exceed more than three inches of mulch in your landscaping beds, and keep mulch about an inch away from stems and tree trunks. Mulch stabilizes soil temperature, prevents weeds, feeds the soil for healthier plants and helps to conserve water. And it recycles itself!
Improper use of fertilizers can damage beneficial soil life essential for healthy soils and plants. Excess chemicals can also find their way into ground water, streams and lakes where they can contaminate drinking water and harm fish and other wildlife. Read and follow product labels carefully before using fertilizer and other lawn chemicals and make sure you avoid application of these products to impervious surfaces to avoid run-off.
pH is a measure of soil acidity or alkalinity and directly affects the availability of nutrients for your plants.
Where is it sunny or shady? What is the pH of your soil? What type of soil (e.g. sandy, clay) do you have in your yard? Look around—are there plants with problems? Where do you want play areas, vegetables, color, views or privacy? How much lawn do you need or want to maintain?
Select plants that grow well in your area of the country and fit the amount of sun, type of soil and water available in your yard. (In general, it makes sense to use low-water plants to save yourself the time and expense of watering). Think about how big a tree or shrub will be when mature (especially next to your house or driveway and near power lines).
Many garden centers and nurseries offer information about pest- and disease-resistant plant varieties. After they're established, they'll save you time and money on pest control.
Prepare the soil by mixing one to three inches of compost into soil in planting beds. For trees and shrubs, mix compost into the whole planting bed, or just plant in existing soil and mulch thoroughly. Set plants at the correct soil level, following instructions provided with your plant. Mulch new plantings and be sure to water even drought-tolerant plants during their first few years especially in the summer and fall until they build deep roots.
Did you know that watering too much or too little is the cause of many common plant problems? You can have healthier plants, save money on water bills and conserve precious water resources by learning to give your lawn and garden just what they need, and no more.
Most plants do best if the soil is allowed to partially dry out between waterings. A loss of shine or footprints remaining after you walk across the lawn indicates that it's time to water. Vegetables and other annuals should be watered at the first sign of wilting, but tougher perennials (plants that live several years) need water only if they stay droopy after it cools off in the evening. Trees and shrubs usually don't need any watering once their roots are fully established (two to five years), except in very dry years.
Some easy ways to lower water bills and get more water to plants include:
Rain gardens are landscaped areas design to soak up rainwater from your roof, driveway, and/or lawn. These gardens are designed to collect rainwater runoff and filter and slowly release it into the ground. A rain garden typically can retain 30 percent more rainwater than a conventional patch of lawn. By reducing the volume and velocity of storm water runoff, rain gardens help reduce soil erosion, filter fine particulates, and capture fertilizer and excess nutrients that can pollute rivers and lakes.

Rain rushes off roofs, pavement and compacted soil. This causes flooding downstream, erodes stream banks and muddies the water, which harms fish and other wildlife. You can help slow this run-off and help the soil hold the moisture plants need in summer.
Only about 5-15 percent of the bugs in your yard are pests. "Good bugs," like the ground beetle and the green lacewing, help control pests.
Pesticides can be effective tools for controlling pests such as insects, weeds and diseases. Be sure you need a pesticide before you use it. On-going pest problems are often a sign that your lawn or garden is not getting what it needs to stay healthy. You need to correct the underlying problem to reduce the chance of pests reappearing. Remember, a holistic—approach is the most effective way to manage pests. Here's how:
Mow higher. Most grasses should be mowed to a height of two to three inches. Taller grass has more leaf surface and deeper roots and eventually chokes out many weeds. Whether it's a bug, disease or weed, you need to identify it to know how to effectively manage it. The cause of ailing plants or grass may not be pests or disease but incorrect mowing or pruning, improper watering or other easily corrected practices. That scary bug could actually be a beneficial "good bug" that eats problem pests.
Accept a few pests, as long as they are not harmful to the long-term effects of the landscape. Natural predators often bring pests under control, but they need time to work. Monitor your landscape to spot signs of pests but don't spray at the first sign of damage—nature may control it for you or plants may outgrow the damage.
Physical controls like traps, barriers, fabric row covers or plants that repel pests can work for some pests.
If a plant, even a tree, has insect, pest or disease problems every year, consider replacing it with a more tolerant or resistant variety or another type of plant that doesn't have these problems.
Avoid overuse of pesticides. When you have a small problem area, treat just that area, not the entire yard.
It's easy to save time and money by putting these steps to work for a beautiful yard.
Mow more frequently when grass is actively growing so that you are only cutting no more than one-third of the height of the grass. This practice minimizes the amount of grass clippings. The desired height of grass varies depending on climate. "Grass cycling," or leaving the clippings on the lawn, doesn't cause thatch build up—but it does make lawns healthier. Soil organisms recycle the clippings into free fertilizer, and you save all the work of bagging. Modern mulching lawn mowers make "grasscycling" even easier and homeowners can reduce their mowing time by 30 to 40 percent by not having to bag clippings.
Choose "natural organic" or "slow-release" fertilizers to reduce nutrient run-off and leaching. Keep fertilizers on the soil and out of the street! Fertilizers that run off are a waste of money and contribute to pollution of streams and lakes. Use fertilizers sparingly. The more you fertilize, the faster the grass grows and the more frequently you have to mow!

Rebuying means rethinking your purchasing habits. Look for products that meet your needs but have a better environmental profile than your current product purchases. Consider biobased, recycled content, water efficiency, energy efficiency, and other environmentally preferable aspects in your purchasing decisions. A few examples include water- and energy-efficient products, organic pesticides and fertilizers, manual or electric yard equipment, and solar landscape lighting. Rebuying is key to sustaining recycling markets and it aids in the development of technology that conserves resources and prevents waste.
