Resurecting this old subject, (the 120 day rule applies). The following is from Marshalls website/webpage.

"Caliente Mustard Seed is not just a green manure - it also acts as a bio-fumigant for the soil. Bio-fumigants suppress various soil-borne pests and diseases by releasing naturally occurring compounds.

The foliage must be crushed or finely chopped for it to release a natural gas (isothiocyanate) which effectively reduces and suppresses a range of harmful nematodes and diseases in the soil".

Old soil in greenhouse borders. anyone any idea how to go about chopping the mustard up when no access is available for a rotary mower or strimmer?

Looking forward to your knowledgeable replies.

Cheers,  Tony.

Sharp spade I guess, or shears snipping downwards once the plant is lying on the soil
