These collars are discs of black heavy-duty fabric impregnated with copper, measuring 12.5 cm (5 inches) in diameter. The collar is cut to the center, ensuring a tight fit around the plant while allowing the stem to grow without restriction. They are effective in preventing cabbage root fly from laying eggs at the base of plants and reduce the risk of larvae reaching plant roots. The copper content also discourages slugs and snails, promoting healthier growth for brassicas and other young garden plants. Additionally, these collars help reduce weed growth by limiting exposed soil and aid in moisture retention for steady growing conditions.

FAQs
How do I install the cabbage collars?
Simply slide the pre-cut collar around the base of your young brassica plant's stem, pressing it into the soil so it fits snugly and covers the exposed soil surface.
What is the purpose of the copper in the collars?
The copper impregnation acts as a deterrent to slugs and snails, discouraging them from crawling onto the collar and reaching the plant.
Can these collars be reused?
Yes, the durable fabric construction allows for reuse in subsequent growing seasons if they remain in good condition after removal.
What size plants are these collars best for?
They are ideal for young brassica plants and seedlings with stems that can fit snugly within the 12.5 cm (5-inch) diameter of the collar.
Will these collars prevent all cabbage root fly damage?
They are designed to prevent the flies from laying eggs at the base of the plant, thereby reducing the risk of root damage from larvae. This significantly enhances protection but complete prevention can depend on various environmental factors.
How do the collars help with weeds?
By covering the soil around the base of the plant, the collars block sunlight from reaching the soil surface, which suppresses the germination and growth of weeds.
Are these collars environmentally friendly?
Yes, they offer a physical barrier method to reduce the need for chemical pesticides and herbicides, supporting more natural gardening practices.
Troubleshooting
Collar is too loose around the stem
Gently adjust the collar, ensuring the fabric edges overlap sufficiently to create a snug fit without damaging the stem.
Slugs or snails still reaching the plant
Ensure the collar is pressed firmly into the soil around the base of the plant, leaving no gaps for pests to bypass. Check that the copper impregnation is still present and effective.
Weeds growing through the collar opening
Re-position the collar to cover any exposed soil around the stem. For larger plants, consider using a second collar or additional mulch.
Collar appears to be restricting plant growth
Carefully check if the stem has thickened significantly. If so, the collar may need to be loosened or removed to prevent girdling. Ensure the cut is open enough to allow for stem expansion.
