1 - Mulch Exhibit
Fifteen mulching materials are displayed to educate consumers about available options. Some materials, such as municipal wood chips, newspaper and grass clippings, can be obtained free, while others such as cocoa hulls, licorice root and pine bark nuggets can be purchased at local garden centers. Mulches are beneficial because they help eliminate weed competition, conserve soil moisture, and protect plants from lawn mower injury. Mulches should be applied to a depth of approximately 2 inches (except for grass clippings, which should be limited to 1 inch) and reapplied annually if much decomposition has taken place. Additional information is available on the mulch fact sheet.
2 - Cinderblock Bin
This bin it relatively inexpensive and quick to build. Although it is not as attractive as other bins, the open design makes turning easy.
3 - Compost Tumbler
Although relatively expensive (approx. $400), this bin will hold a lot of yard waste - up to 18 bushels. The hand crank and gears make turning easy. Also available in smaller sizes.
4 - Three Section Wood and Hardware Cloth Bin
This bin is termed the Cadillac of compost bins because of its attractiveness and ability to handle large volumes of material. The bin's three sections allow the material to be turned more easily. Fresh yard waste is placed in the first bin and after approximately one month can be turned into the next bin. This leaves the first bin available for new material. The process is then repeated in another month and is effectively a composting assembly line. The cost of materials for this bin is approximately $100 - $125. It will last for many years if treated lumber is used.
5 - Earth Machine Bin
This commercial bin was donated by Norseman Plastics Limited, 2296 Kenmore Avenue, Buffalo, New York 14207. Literature from the company claims it will convert yard waste to compost in 6.- 8 weeks, although this would require constant turning. Additional water must be supplied because rainwater cannot enter the unit.
6 - New Zealand Box
This unit is attractive, easy to construct, and if treated lumber is used, should last many years. It has slotted sides to allow for increased air circulation. If the bin is full, turning the material can be difficult.
7 - Green Magic Tumbler
This commercial bin was donated by Gardeners Supply, 128 Intervale Road, Burlington, Vermont 05401. The unit holds a lot, but additional moisture must be added if the material is dry. If the bin becomes too full, it may be difficult to turn.
8 - Hardware Cloth Bin
This bin is easy to construct and relatively inexpensive. It allows for good air circulation and can be made to any dimensions.
9 - Rosi Metal Tumbler
This commercial bin was donated by Lescha North America, PO Box 266, Bolton, Ontario. Oxygen is continuously supplied to the material and moisture is readily available. Turning the unit is relatively easy and new material can be added without delaying the composting process. This unit is expensive and difficult to assemble, but it should last for quite a while. Retrieving the material is easy (it falls through the holes). However, some large pieces also fall out that must be returned to the compost bin.
