Butterflies are beautiful creatures, fluttering flashes of colour in the garden, but don’t forget their purpose is to find somewhere to lay their eggs and start the next generation.
When I see the cabbage whites flying about, I begin to worry. Once their eggs hatch into caterpillars they’ll munch away and reduce the leaves to mere skeletons seemingly overnight
Prevention is the best defence and that means netting. If the butterflies can’t get onto the plant they can’t lay their eggs. Don’t just lay netting over the plants, you’ll find the butterflies will lay through the net so not effective. Support the netting off the plants.
One quick and cheap method is to pop bamboo canes in around and among the plants and then upended milk containers or soft drink bottles over the canes. Drape the netting over and keep it taught by pinning it down around the edges.
Incidentally, site supporter Harrod Horticultural sell effective soft 7mm butterfly netting which is UV stabilised – so it can be re-used season after season. Their netting saver packs offer great value too.
