Hi,

New to this forum and looking for a bit of advice.

I am new to growing here in Scotland . 

I have just pulled out some of my turnips and discovered i have root worm. (now pulled them all out). I discovered (after trawling the net) i have planted a bit too early - also the fact i never covered the seedlings early doors hasnt helped.

I am wondering-- is it ok to put brassicas in the 'infected' soil?. (i have cabbage and  broccoli  grown and now ready to be planted out).

Or will the root worm still be in the soil and attack these new plants?

Any help or advice would be most gratefully received..

Thank you in advance

Suzanne

Hi Suzanne, depends what 'root worm' is.  If it's cabbage root fly which attacks all brassicas - see here:

then planting any other brassicas in their place will very likely be a problem.  You could treat the area with Nemasys Grow Your Own (as mentioned in the RHS link above) which is a mixture of nematodes which prey on cabbage root fly (and many other pests) and will help to clear up the problem.  Crop rotation is a must once you have had a root fly infestation, so don't grow any brassicas in that piece of ground next year.
