Compost/Mined Lime Blends

Nicasio Blend
Sonoma CompostThis dark, rich, premium quality compost is made from recycled yard trimmings, dairy manure and horse manure. Nicasio Blend is recommended for applications that do not require high nitrogen content such as trees, shrubs, grape vines and natives. Or, for high nitrogen loving plants you can supplement nitrogen to meet the plant's needs.

Provides valuable organic matter to soil, making it easier to work and more productive. In sandy soil it increases moisture-holding capacity, making soil nutrients more available to plants. In heavy clay soils, porosity is increased which improves aeration in the root zone and overall drainage.

Nicasio Blend provides a wealth of slow release nutrients and beneficial microbes to your soil and plants. It's screened to approximately <1/2".

Vineyard Mulch, Screened
Vineyard MulchAn affordable, organic alternative to expensive bark products, Screened Vineyard Mulch provides great background color and texture in landscaping applications. It suppresses weeds, conserves moisture, moderates soil temperatures, and controls erosion.
(Click picture to enlarge)

Vineyard Mulch undergoes a brief composting process at over 131°F that renders it virtually free of weed seeds and plant pathogens. To activate the process water from a dairy manure pond was used. As it slowly breaks down, it provides the organic matter, nutrients and microbes that help plants thrive.

Worms thrive in soils that have a generous layer of Vineyard Mulch. Their tunneling activities allow oxygen to get to plant roots and their castings provide a beneficial nutrient input.

Fungi are prolific in mulches since they are working hard to break this material down. This fungal activity plays a crucial role in improving soil structure by aggregating the soil. Occasionally, during the wet season, these fungi make their presence known by producing fruiting bodies: mushrooms. This a natural occurence, inherent to decomposition. For those who do not appreciate those 'guests' can simple rake the mushrooms and they will disappear rapidly.

Vineyard Mulch is ideal for the demanding needs of North Coast grape growers. It's particularly suited for use on steep, hillside vineyards and when properly applied will reduce soil loss from erosion by up to 95%. It's easily applied by hand or with a tractor pulled spreader.

Ultra-Light Mulch
Path MulchThe hybrid mulch that has qualities of compost will finish off any landscape just perfectly. While the mulch will initially act as a weed suppressant, as it breaks down it will help feed your soil. As the name implies, this mulch is lightweight and easy to work with. Landscapers specify Ultra-Light Mulch when a neat appearance or distinctive border is desired.

Amended Soil -- Now Available
Feather-Lite Amended SoilPlant directly into Amended Soil. It's great for filling raised beds, replacing poor quality soil, adding elevation or leveling a project site, or filling in behind a retaining wall.
(Click picture to enlarge)

Amended Soil is a good looking blend of clean soil and a base compost. Since a high quality topsoil is used, rather than a mined soil, no weed-free guarantees can be made.
