Jute netting is ideal for erosion control, especially when laid over a layer of mulch. The jute helps stabilize the mulch, and together they provide a series of small impediments to water flow, thus inhibiting erosion. You can install jute netting in erosion-prone areas such as a newly cut bank or a slope where fire has cleared away vegetation. To work properly, however, jute netting must be laid out and anchored properly.
Things You'll Need
- Shovel or trenching tool
- Jute netting, equal in size to the area you are mulching with a 4-inch overlap between sheets
- Galvanized anchor "J" pins, at least 10 inches long, or galvanized staples, at least 6 inches long
- Mallet (optional)

Dig a trench at least 8 inches deep all the way across the top of the mulched slope where you will install the netting; the U.S. Department of Agriculture's National Resources Conservation Service recommends extending this trench about a foot on either side.
Unroll the first section of jute netting lengthwise down the slope, leaving enough at the top to extend through the trench and 6 inches beyond. In severe erosion conditions, extend the rolls 3 feet beyond the bottom of the mulched area.
Unroll the second section of jute netting in the same direction. Overlap parallel sides (lengthwise) by at least 4 inches; overlap ends by 3 feet.
Repeat Step 3 until the entire surface is covered.
Fill in the trench at the top of the slope, burying a section of netting, and step on the replaced soil to compact it into the trench.
Drive the anchor pins or staples straight down into the soil no more than 1 foot apart across the top of the netting at the top of the slope, catching an intersection of the jute beneath the bent top as you do so. In hard, dry soils, you may need a mallet to drive them fully in.
Drive anchor pins or staples into the rest of the netting using the same technique. Across every overlapping end, space them no more than 1 foot apart; down the overlapping long sides, space them no more than 5 feet apart. If the roll is more than 3 feet wide, place pins or anchors down the center of the rolls, no more than 5 feet apart.
