Soil, Compost & Mulch

 

How Much Mulch? What Kind of Soil? What?

Every once in a while at Swan River Gardens we will find some poor soul out in our bulk material yard walking from mulch mountain to mulch mountain trying to decide which one to get. Or someone comes in and asks for ‘dirt’ and suddenly faces what seems like just too many choices for such a simple request. Let’s try to sort this all out so you can walk in and confidently get what you need and want for every job.

Swan River Gardens sells garden soil, potting soil, soil conditioner and compost to grow plants in. We also sell chipped bark for mulch in four sizes, mini, small, medium and walk on. All these products are available bagged or in bulk by the yard and each kind is priced individually. Partial yards are also available. Our bulk products come from Mountain West and Glacier Gold, both local producers.

A cubic yard is equal to 27 square feet. In other words, it represents the volume of a box that measures 3 feet on all sides. For comparison, a raised one foot high bed, 3 feet wide and 9 feet long would also be one cubic yard. See the chart at the end of this article for formulas to figure out how much material you need. As far as how much a cubic yard weighs, that depends on the material and the water content. Evenly moist topsoil weighs about 90 pounds per cubic foot so a full yard of it will weigh about 2400 pounds or so. A full size standard half ton pickup can just about handle this amount so you should plan loads accordingly. The Swan River Gardens dump truck can carry about 7 yards of topsoil at one time. Obviously bark mulch is lighter and rock is heavier so you should adjust your plans to fit. Swan River Gardens offers delivery for a fee based on mileage.

Here is the scoop on the soil & mulch products we offer

Soil Mixes for growing plants:

Swan River 4 Way

Swan River Gardens 4-Way Mix: This custom blend contains compost, peat moss, sand and fine bark. This is what we plant our shrubs and trees in pots with. It is a great mix for raised garden beds or to make any garden soil better. This is the best choice for a new garden. It can also be used in containers especially ones you want to grow vegetables in. Annuals will do fine too but you may want to mix in some perlite to loosen the soil up even more. Available only in bulk.

Glacier Gold Grower’s Blend Potting Soil: Another fine local product that contains compost, perlite, coconut coir and peat moss. This is a premium blend for gardeners who grow plants that are a little bit fussy about soil conditions. For container plantings this mix will drain well and offer a little more nutrient from the compost than plain potting soil. It is what Swan River Gardens uses to plant the majority of our annuals in pots and our custom container plantings. You can usually get 2-3 seasons out of this mix in your containers if you add a little compost in spring. Available in 1.5cf bag or in bulk.

BULK SRG Sifted

SRG Planting Mix

SRG Planting Mix: This mix comes from Swan River Gardens own compost. Old plants, leaves and recycled potting soil are composted here on site then mixed with washed sand, peat moss, top soil and fertilizer then sifted. Great for refreshing your garden or planting trees and shrubs. SRG Compost Blend Has not been sterilized and is our most nutrient rich mix. Available only in bulk. 

 

Products to Improve Your Soil:

BULK EKO Compost

EKO Compost

EKO Compost: is 100% Organic. It is thoroughly cured compost. Products that are only partially decomposed can actually reduce the amount of nitrogen available to your plants, because the micro-organisms will use the nitrogen to finish decomposing the material.EKO Compost uses only untreated wood products for a consistent mix due to its controlled quality ingredients. Available in bulk or 1.5cf bags.

GG Compost

GG Compost

Glacier Gold Compost: Locally produced compost made of forest products, organic matter & bio-solids. Bio-solids are waste from sewage treatment. In large urban areas, such material has been found to be contaminated with toxic waste but here in the Flathead Valley we do not have the kind of industry that contaminates the waste stream therefore we can say with confidence that Glacier Gold Compost is safe to use. Use it to amend garden soil to add nutrients and texture. You can use it to rejuvenate container soil and to top dress the strawberry or raspberry patch in spring. With very high nutrient value, this is GOOD STUFF! Available in bags or in bulk.

Soil pep is an excellent clay buster! It can also be used as mulch to top dress perennial beds or fruit patches. It is less formal than bark or rock and does not contain weed seed so it can be an excellent for weed suppression. It is made up of finely ground bark & chips and does not have much nutrient value. You should add compost to it or use granulated fertilizer to amend soil pep’s nutrient levels. Available in bags or in bulk.

Products for Mulch: Mulch serves several important purposes in the garden world. They are a great way to save time in the garden. Mulch can help suppress weeds and hold moisture in. For some plants such as clematis mulch helps keep roots cool, something the vine needs for good flowering. Mulch also makes good paths to keep mud off feet, both yours and your pet’s.
