I want to sow caliente mustard as a green manure. It is a biofumigant, if you can dig it in VERY fast after crushing it.
The reason is that I'm plagued with carrot root fly, and I've come to the conclusion that as they overwinter in the soil it certainly wouldn't hurt to try; and green manure is said to be almost as good as the real thing.
I really want to know how long it takes to grow to the stage you can dig it in?
And does anyone have any comments about the use to get rid of the carrot root fly? I know it works for some nasties.
Hope you can help.
If you've got the root fly overwintering in your soil, apart from giving it a thorough dig to expose the eggs of them (and other nasties like slugs) to the birds, you can use the nemasys grow-your-own thing to try to get rid of them once it warms up and and the eggs hatch. That would be faster and a sure-fire way to get rid of the bu88ers.
Have you had any luck with growing carrots flyaway or resistafly? Or growing them alongside a sacrificial carrot crop (they're supposed to nibble the resitant varieties, think knickers to that for a game of soldiers and gobble up the sacrificial variety of carrots.
Trying carrots for the first time this year, so will be trying this, if it doesn't work next year will be using the nemasys stuff.
hi all, i read the nettle tea or comfry tea was good for spraying as a carrot fly deterant as long as its watered to a weak looking tea colour ,also gardeners world mag had something in as well
good luck Alan4711
