Slug collar vs cabbage collar

Updated: 23 October 2026

You have set brassicas out, and either the leaves are lace by morning or the plants wilt while the foliage still looks whole. A slug collar vs cabbage collar search on amazon.co.uk mixes a tall green ring with a flat disc. The ring is a climbing barrier with a downward lip. The disc, in the RHS cabbage root fly method, is about 8–15 cm so eggs stay off the soil at the stem. The [snail collar comparison](/hub/pest-control/snail-collar) holds the ten listings. This page says which shape matches the damage. We did not run a garden trial. A purchase through our links can earn a commission at no extra cost to you.

Two different failures

Shredded leaves on a small lettuce, bean, or young cabbage are a climb from the soil at night. The matching object is a green PET or plastic ring, pushed in, open at the top, with a lip bent down. HanYun states 21 cm by 12 cm. One McBlast UK buyer still had slugs climb the side and eat the cabbages. Wilting with the leaves still largely whole is cabbage root fly, Delia radicum, in the RHS account: eggs at the stem, larvae in the roots. The collar is flat, about 8–15 cm, fitted at planting. Mesh is stronger when the whole bed must be closed, because flies already in that soil emerge underneath a gap. Lace on a small plant means the ring. A new brassica wilting from the base means the disc.

What you are actually buying

The flat pieces in this set are 25-packs with a slit and no lip. Three are listed at 15 cm, at the top of the RHS range. The unbranded black felt pack is about £6.99 and 4.4 from 52 reviews, the largest file here. Nogotizam is about £4.09 for 25 polyethylene discs, 4.5 from four reviews. Reyuvidep is about £3.59, material unnamed, with no reviews. Bettsolt is felt, 25 pieces, about £8.99, stated at 27 cm. The packed size on the same page is 15 x 8 x 1.5 cm, so use the diameter line. There are no reviews. Wider than 8–15 cm is a sizing fact, and it is not the RHS size for a narrow transplant. Ghligna is the crossed name. The title says cabbage collars. The piece is 20 green PET rings, 23 cm outer and 11.5 cm high, about £15.99, with no star line. An open ring does not cover the soil around the stem. Listings whose centimetres disagree are on the slug collar buying guide.

Which side, with a condition

Use the 15 cm flat disc when the worry is Delia radicum on a new transplant with a narrow stem. Fit it at planting and check it after wind. Shredded leaves are the wrong damage for a disc. Nogotizam is the polyethylene alternative on four reviews. Use a raised ring when the plant is still small and the loss is on the leaves. A May seedling is a different fit from a sprawling July plant. McBlast’s climb-and-eat review is the limit of a lip. Skip Ghligna if you wanted a cabbage collar and the parcel is an 11.5 cm wall with no reviews. If the bed is the unit of protection, a collar around one stem is the wrong scale.

When neither collar is the whole answer

Mesh is the RHS cover when a whole brassica row must be sealed. One disc leaves the neighbours open, and a loose edge lets flies already in the soil emerge inside. GrowVeg notes wind and rot on home-made 10–15 cm discs. One pack will not stop leaf slugs and root maggots together. Both symptoms mean two buys, or mesh for the fly and a ring only on the grazed plants. None of these listings carries an HSE number, and the RHS did not test these packs.

Common questions

Are a slug collar and a cabbage collar the same product?
They are different objects sold under both names. A slug collar here is a raised ring with a lip. A cabbage collar, on the RHS page, is a flat disc about 8–15 cm. Ghligna’s title says cabbage collars, and the piece is a PET ring. Use the height, not the word cabbage.
When do I choose the 15 cm felt disc?
Choose it for a new brassica when the risk is cabbage root fly at a narrow stem, from about April to September. The unbranded 15 cm felt 25-pack is about £6.99 and 4.4 from 52 reviews. Fit it at planting and weight it in wind. It has no wall.
When do I choose a raised PET ring?
Choose it when leaves are being eaten and the crown still fits through the ring. HanYun’s 21 cm by 12 cm lines agree. Ghligna states 23 cm by 11.5 cm and has no reviews here. A McBlast UK review records slugs climbing over and eating the cabbages.
Is 27 cm better for root fly because it is larger?
The RHS collar is about 8–15 cm. Bettsolt’s felt is listed at 27 cm, about £8.99 for 25, with no reviews here. Extra width can cover a thicker stem and can also catch more wind. For a narrow transplant it sits outside that range.
Why did slugs sit under the felt?
A UK review of the 15 cm felt pack found slugs sleeping underneath and said to check. Moisture at the stem leaves a damp gap a slug can use by day. The reviews do not count larvae. Lift the disc when you water.
What if the whole brassica bed wilts anyway?
A collar on one stem does not close a bed. The RHS treats sealed mesh as the stronger cover, because flies already in the soil emerge under a gap. If every transplant collapses, ask a local adviser, or the allotment committee, rather than buying a second shape.
