Netting is a useful tool for the home gardener and can provide protection from harmful insects such as cabbage beetles, root maggots and tomato worms. The nets will also discourage animals including rabbits, deer and birds from nibbling on your plants. While laying netting directly onto plants can provide protection, it may also crush fragile plants, which is why installing supportive hoops beforehand is well worth the investment of time required.
Hammer two 45 cm (18 inch) rebar stakes into the ground on either side of the row of garden vegetables so that the stakes are spaced 90 cm (3 feet) apart. Install additional pairs of stakes every 60 to 90 cm (2 to 3 feet) along the entire row.
Cut 2.5 cm (1 inch) thick polythene pipe into 15 cm (6 inch) lengths with a knife. You will need one length of pipe for each pair of rebar stakes you installed.
Slip each end of the pipe onto one of the rebar stakes to create a series of arches extending over the garden row.
Buy a length of tulle netting in 225 cm (90 inch) width that is long enough to cover the entire garden row with 60 to 90 cm (1 to 2 feet) overhanging the ends. Tulle netting is available in most fabric shops and may be found with wedding fabrics.
Place the length of tulle netting on top of the polythene hoops so that the excess fabric hangs over the beginning and end of the garden row.
Place one or two sandbags on each end of the fabric to hold it in place.
Remove the fabric from the garden if it becomes very dirty and hang it from a clothesline. Spray the fabric with a garden hose to remove the dirt and then allow it to dry completely before placing it back over your plants.
