Brassica Problems

Answered by Gavin Posted in Category Pest Control & Nature

Hi Gavin

I am a first time Gardner in the Ayr area of Scotland.

I am trying to grow veg in large raised beds. I have been very successful in that everything that I ave planted has come on really well, but my cabbages and sprouts have been eaten to nothing! My cabbages have eggs
and caterpillars all over them and sprouts are lie skeletons! I am so disappointed.

Can you give me ant advice on avoiding this in future? Also, is it too late to plant more?



Dear Carol-Ann

If you remove the worst affected leaves and remove what caterpillars you can see by hand and treat appropriately then you may be able to save your crop yet!

If it looks like caterpillars are the problem then you can treat with nemasys caterpillar killer Ideally though you need to prevent the butterflies from laying eggs on your plants in the first place. This can be achieved by means of butterfly proof netting or something similar.

If the weather stays favourable then its probably worth starting some more, but keep them away from those caterpillars!


Best regards,

Believe it or not I began my career as a cobbler, however, after 11 years in the trade I decided to pursue my boyhood dream of studying insects (this I had already been doing for much of my life!). Whilst studying towards this career change I applied for a part-time post in the entomology department at one of the UK's leading plant biological science research institutes. I was fortunate enough to secure the post, to which I have now occupied for 12 years full-time.
