  • Mulch Matters Handout
    Mulch Matters What is mulch? Most simply, it is a material used to cover soil. Mulch in ornamental gardens can be compared to the fallen leaves and twigs in native habitats. In horticulture applications, it may be made of plant residues, rock, or synthetic materials. Why mulch matters How we use mulch can have significant positive or negative impacts on soil condition and plant health. For most gardens in our region, an annual application of course-textured organic mulch is one of the best things you can do to maintain good soil and healthy plants. Applied correctly, mulch will protect against soil compaction and erosion, improve water penetration and retention, and suppress weed growth. Weeds are much easier to pull from the well conditioned soil beneath good mulch. Decomposing mulch acts as a slow-release fertilizer while retuning valuable humus to the ground. Coarse organic mulch supports a variety of beneficial insects, worms, and fungi which in turn contribute good conditions for root growth. Using the right kind of mulch for the job and applying it correctly offers multiple benefits, and helps avoid common pitfalls of faulty applications. Biology matters While aesthetics is often a first consideration, is should be the lesser of consideration when choosing mulch material. Soil is alive. Use materials that support soil building organisms and soil biological functions for healthier and more aesthetic plantings. What makes good mulch? Overall, coarse textured mulch is best. For landscape beds, wood chips, leaf mold, or compost with lots of woody content are good examples. In flower and vegetable gardens, straw is a good option.

Prepare for the team compost cook-off Soil amendment Thermophile Introduction Clark County produces about 75,000 tons of organic landfill waste each year. Our waste is hauled to local transfer stations where it is packed onto barges and carried 160 miles upriver to Finley Buttes Regional Landfill, in Morrow County, OR. Each week, three barges with 70 shipping containers travel upriver. Each of these shipping containers weighs 30-31 tons. Food wastes are the largest single component of organic waste. They accounted for over 50,000 tons (17%) of the waste stream. Yard & Garden Waste - Leaves & Grass accounts for a portion of landfilled organics, making up 6%, or 19,000 tons. In addition to taking up landfill space and costing money and energy to transport, organics in a landfill decompose aenerobically and release methane, a gas contributing to global warming. Another asset that is too precious to waste is good, edible food. We know that recycling, although valuable, is the least effective tool in our waste reduction kit, we should always look to reduce and reuse materials first.

  • Upcoming Permaculture Workshops
    Issue 16 November 4, 2012 Upcoming Permaculture Workshops Many of Amma’s communities, including San Ramon M. A. Center, Michigan M.A. Center and Amritapuri are beginning to incorporate Permaculture Design Practices. Here in the Pacific Northwest, Netsah Zylinsky, a Permaculture instructor from Oak Harbor, is excited to share her knowledge of Permaculture with our GreenFriends Community. We are currently looking at offering the workshops in January/February. We will keep everyone posted as dates and locations are confirmed. In an effort to begin to introduce our community to Permaculture Netsah writes: Permaculture is based on three primary principles: 1. Care for the earth 2. Care for the people 3. Return the surplus back to the whole (people, communities, earth, etc.) In Permaculture, we design landscapes that mimic nature; with nature, we help to co-create a sustainable, diverse design. The big picture of the design includes as many multiple functions as we can imagine. Every function is supported by many elements. For example, functions like rain water collection include all elements of water that enter the land. Other functions include soil building and food production, which include elements of organic gardening, composting, companion plantings, and designing sustainable food forests. The concept of Permaculture also spreads into our lives and our communities. It includes our sources of energy, green building practices and diverse creative projects. Bill Mollison “the father of Permaculture” shares, “Permaculture is the study of the design of those sustainable or enduring systems that support human society; agricultural and intellectual, traditional and scientific, architectural, financial and legal. It is the study of integrated systems, for the purpose of better design and application of such systems.

  • 7 Secrets to a Successful Garden Cherie H.Gundersen
    7 Secrets to a Successful Garden Cherie H.Gundersen 1. Planning: Select areas suited to the type of plants, sunlight, drainage, available water and soil nutrients, as these are all important factors to be considered. Keep high-maintenance areas small. Small well cultivated areas are better than large unmanageable ones. Plan based on your needs and desires. Know the space requirements of the particular plants and seeds you choose. Draw out your plan and adjust it as necessary during the planting. 2. Soil preparation: Add organic matter to the soil to improve soil structure and nutrient content for healthy growth and disease resistance. Types of materials that will help to improve your soil are: 1. Compost – old leaves, grass, etc. (contact local landfill for a list of available compost--generally very reasonable) 2. Manure – aged is usually best; steer, turkey, etc: no dog. 3. Leaf mold 4. Wood chips – finely chopped 5. Aged sawdust 6. Peat moss (Avoid shredded newspapers for food gardens.) For container gardens a prepared mixture of vermiculite, peat moss and fertilizer is best. This mixture, sold by seed dealers and garden supply centers comes ready for use; it has several advantages over soil. It is free of plant disease organisms and weed seeds, it holds moisture and plant nutrients well, and it is very lightweight and portable. 3. Selection of plants and seeds: Check on which varieties are best for your area. (For a list call your local Cooperative Extension Service office.) Estimated days to harvest, planting time and germination period and space requirements are some factors to consider.

Benefits of mulch Mulches have many positive effects on soils. In general, organic mulches conserve water, reduce weeds, improve soil quality, and enhance plant growth. Summer water conservation Is mulching an effective way to cut back on summer irrigation? Mulching reduces irrigation needs by reducing surface evaporation and runoff (Figure 1).
