Butterfly netting provides protection for crops often eaten by caterpillars. The mesh size of butterfly netting is too small for butterflies to enter and lay their eggs on the crops. This in itself is not a problem, but when the caterpillars emerge they can devastate a crop. When left in place for the whole of the growing cycle, the final outcome from using butterfly netting can be a much healthier and larger crop. Standard width 3.5 metres (11ft 4) height 1.9 metres (6ft 3) lengths from 2 metres upwards, other widths available from 2.5 metres to 4 metres. Although the 7mm mesh netting is small enough to keep out the cabbage white butterfly, it will also exclude a number of bees and other beneficial insects which help with pollination. For protecting vegetables that require pollination we would recommend removing the net during the flowering period or that you chose a larger mesh netting such as our 20mm x 20mm diamond mesh bird netting.
Soft to the touch but definitely hard on butterflies, this netting is the ideal material to keep your home-grown vegetables and brassicas in particular caterpillar-free. A superior weighted netting, weighing in at 17g per square metre. Perfect for protecting your brassica crop and other vegetables in the kitchen garden or on the allotment. Whatever structure is used to support butterfly netting, it is important to securely peg or weigh down the bottom of the net to ensure that there are no gaps. The butterflies will be more likely to lay their eggs on the nasturtiums and the caterpillars will destroy the nasturtiums rather than your brassicas. Inspect leaves regularly and remove eggs/caterpillarsOk, so the first job is to decide how big you want your brassica cage to be, I made mine brassica cage 3.5meters x 0.9 meters, but in hindsight, I wish I had made four smaller ones rather than two big ones; they are a little challenging to move about so smaller is better. Butterfly netting is a must for both the serious gardener and the 'grown your own' novice alike, although butterflies are not all bad news - they feed on nectar and pollinate flowers – their caterpillars can do extraordinary damage to your brassica crops. Soft Mesh Butterfly Netting issoft to the touch but definitely hard on butterflies, this butterfly netting is the ideal material to keep your home grown vegetables - and brassicas in particular - caterpillar-free. Make sure the brassica net is propped up by hoops that are as high as the plants will get so that the net can stay there for the whole season. You can also prop the netting up with bamboo canes topped with jars. For broccoli, cavolo nero, red russian kale, and sprouts, 1.5m tall is about right. For cabbages, cauliflower, romanesco, turnips/swede and curly kale, 60-70cm would be fine. Choose mesh netting as pictured for best protection. Plant nasturtiums as a sacrificial crop nearby
The butterfly netting is made from strong HDPE and UV stabilised. With the feel of soft fabric to touch and durable enough to last for many years. Trim off excess netting using the scissors, leaving a 2-3″ skirt all around. Fold this under and secure it with staples to the base of the cages. Finally, fire in a few pins along the top support rail to prevent any movement of the netting. You'll frustrate the cabbage white butterflies’ season after season with this anti butterfly netting as the 100% polyethylene construction gives a long-life expectancy.The netting is lightweight and can be suspended on a structure of garden canes or hoops. If using canes, it is worth protecting the caps that touch the net to ensure that these do not damage the mesh. The recommended mesh size for brassicas is typically 1/4 inch or 0.6 centimeters. This size is small enough to prevent common pests like cabbage worms and flea beetles from entering the cage while allowing proper airflow and sunlight penetration. Cover your crops – use a very fine mesh netting to protect plants from pests such as flea beetle, egg-laying moths and butterflies (which produce caterpillars) and birds. These net cloches allow sunlight and water to pass through while preventing pests from getting in
This netting has a mesh size too compact for bees to fit through. As a result, if you are growing crops that need pollinating, remove this netting during flowering. Once you’ve got your frames in place, you can cover them with a sheet of horticultural fleece or netting to protect plants from pests. Be sure to secure the cover to the ground – you can use heavy stones. All you need is a few equal lengths of old hosepipe measuring around 100-130cm (we’ve used an old drip hose) and a few short lengths of bamboo, approx 40-50cm long. A Brassica cage should ideally be at least 2 feet (60 cm) high to provide sufficient space for the plants to grow and to protect them from pests. However, for taller Brassica varieties, such as kale or Brussels sprouts, a height of 3-4 feet (90-120 cm) may be necessary to accommodate their vertical growth. The cage should be tall enough for adequate airflow and easy access for maintenance and harvesting.You'll frustrate the cabbage white butterflies season after season with this anti butterfly netting as the 100% polyethylene construction gives a long life expectancy and the multifilament technology used in the manufacture provides a soft, lightweight yet high strength netting. The soft butterfly netting is light enough to lay directly over crops and strong enough to be used to cover frames, cages, or hoops.
One of the biggest challenges when growing brassicas is dealing with pests. Common pests that affect brassicas include pigeons, caterpillars, aphids and flea beetle. While pesticides can be effective, they can also harm beneficial insects and pollinators. Instead, try these organic methods to protect your brassicas instead:
The final job is to cover the brassica cage with the scaffolding netting. I selected the green netting as the blue can look a bit much on your plot. When you’re happy with the position, secure one long edge to the frame using the staples. The high strength knitted anti-butterfly netting can be draped over the frame and secured to the soil using the supplied plastic ground pegs.
