How To Make Your Own Cabbage Collars

I’ve decided to do some “how to” blog posts on DIY garden projects, as I’m often asked for tips from fellow plot holders and gardeners. Hopefully this’ll be the first of many.

Cabbages are a staple of most vegetable gardens but need lots of care and attention. Cabbages are a member of the bassica family and are therefore plagued by a variety of pests. They are well worth growing though as they are very tasty when grown yourself, nothing at all like the shop bought cabbages and they also look gorgeous on the plot.

Not only do birds love them, they are also plagued by slugs, caterpillars and the dreaded cabbage root fly. The cabbage root fly lays it’s eggs on the soil at the base of your cabbages; when the eggs hatch, the maggots tunnel down to munch on the roots, effectively destroying your cabbage. The hearts will not form properly  and the leaves will wilt and often turn a blue colour. To protect your cabbages from the root fly, you can install some cabbage collars at the base of your cabbage. You can buy these in most garden centres but they’re fairly pricey and often flimsy so I decided to make my own. They were very easy to make and you can use materials you have lying around the house.

I used a doormat to make the collars, old carpet or carpet underlay is also ideal, anything that won’t warp when wet.

To make the collars, you will need: one doormat/some old carpet, an old CD, a marker or pen and a scissors.

Step 1: Using a CD as a template, draw circles for your collars on the mat.

Step 2: Cut the circles out using a scissors.

Step 3: Cut a straight line halfway through the circle and then cut either side so it forms a Y shape.

Step 4: Place the collars around your cabbages.

Water the collars a bit to flatten them to the ground, and there you have it, quick, cheap and easy homemade cabbage collars.

  1. This is AWESOME! I wish I’d known this back in March when I planted my purple cabbage. You’ll see my saga of dealing with garden pests in my next episode of “Late Bloomer.” This easy trick could have saved me a lot of trouble. Thanks!
