Grapes are a fruit that has been around for thousands of years, and they have been grown in every climate through time. While the grapes can grow without being covered, you may want to protect them from pests or harsh weather by covering them with tunnel netting. This is especially true if you live in a cold region where the grapevines may not survive without some insulation.

Tunnel Netting is found to increase fruit yield by 50%, holds humidity, and keep the crop free from insects and diseases. The cost for this technique is low and the installation process takes about a week.

What is Tunnel Netting

Tunnel netting is a series of light frames connected by wires are erected at intervals along the row to support the net and hold it away from the tree.

The nets are placed over the frame only when the fruit approaches maturity and are taken down after harvest.

Netting is regarded as an environmentally friendly and socially responsible approach to the problem of vertebrate pest control.

How to Grow Grapes Under Tunnel Netting?

Step 1: Select an area with well-drained soil.

The site should receive at least six hours of direct sunlight daily. Dig a hole at least 2 feet deep that is large enough to accommodate the vine’s roots without bending them or crowding them together.

Step 2: Place the vine in the hole and backfill with soil

Place the vine in the hole and backfill with soil, covering all but two buds on the crown of the plant. Water thoroughly then mulch with straw or wood chips to retain moisture and suppress weeds.

Step 3: Install the high tunnel over top of the vines when they reach 4 inches tall.

The tunnel should be 8 feet wide by 10 feet long with a center height of 6 feet. You can create your high tunnel or purchase one online. The tunnels are not heated but can raise temperature levels by about 10 degrees Fahrenheit during winter months, which protects vines from potentially damaging winter frosts and freezes.

Step 4: Use Vineyard Netting

Provided a suitable mesh size is chosen, the net can protect against a wide range of potential problem animals such as

  • Flying foxes
  • Birds
  • Fruit piercing moths
  • Fruit flies, wallabies
  • Hares, and possums.

 Appropriate netting can also protect orchards from wind and hail damage.

Step 4: Install end walls for the tunnel

You should Install end walls for the tunnel so that you may prop open the doors during warm weather days and humid nights to aid in ventilation.

Step 5: Construct four hoops out of a 3/4 inch galvanized pipe.

The hoops should be spaced 3 feet apart along each side of the structure, with one end being lower than the other so that they form an arch with a slope of 30 degrees when connected by twine or wire at each corner

Step 7: Secure 6-foot cable ties to each hoop

Secure 6-foot cable ties to each hoop and secure them around three wooden stakes placed equidistant from one another around each hoop

Step 8: Water regularly

Water your vineyard during dry weather, providing 1 inch of water weekly throughout the growing season. Use a soaker hose or drip irrigation system. Apply a balanced fertilizer such as 10-10-10 once each month.

Tips 9: Wait until your vines grow up to 4 inches

Wait until your vines grow up to 4 inches tall before installing tunnel netting over them to protect them for the rest of the season and beyond. Tunnel netting is made out of durable plastic materials
