Brussels sprouts

I'll give you a high stake bet which you cannot lose, I bet 1kg of onions they will grow, consider growing carrots also, in the UK they are troubled by carrot fly and they tend to grow them there under fleece, this method can be used there in PH, if they are sown broadcast in a broad row 12inch wide and NEVER thinned out, the thinning causes the smell that attracts the fly in the first place , at harvest time when you pull a bunch of the roots you get a mix or large and small, this method has been tried and tested by myself and works very well.
