Cabbage Brassica Collars - 25 - Copper

These collars are specifically designed for brassica plants, including cabbage, broccoli, cauliflower, kale, Brussels sprouts, and related varieties, which are susceptible to cabbage root fly.

The copper impregnation is designed to provide protection throughout the growing season. While the copper may naturally oxidize over time, its deterrent effect typically remains effective for at least one season of use.

Yes, these collars are an excellent choice for organic gardening as they provide a physical barrier and utilize copper, a naturally occurring element, to deter pests without the need for chemical pesticides.

When fitted correctly, the collars should not harm your plants. The design allows for stem growth. Avoid overtightening or burying the collar too deep, which could impede growth.

The copper impregnation creates a mild electrical charge that deters pests like slugs, snails, and cabbage root flies from crawling onto or burrowing near the plant stem.

Ensure the collar is pushed firmly into the soil and creates a complete seal around the stem. Check if the collar has been outgrown and needs adjustment or replacement.

Verify that the collar is properly seated at soil level and that no gaps exist. Consider combining collar use with other organic pest control methods if infestation is severe.

Carefully cut a small additional slit or widen the existing one to allow more space for the stem as it thickens. Ensure the collar is not buried too deeply or tightly around the stem.

Gently flex the collar to open it slightly, then position it around the stem and press it down to the soil level. The cut design is intended to allow flexibility.
