Post #6 by Jim Lindl: Natural Weed Killer!

Hello again everybody,

No! It’s not the weed whacker in these pictures that kills the weeds! The natural weed killer present in these pictures is in the phyto-chemical released from these dense mustard talks that I’m about to chop into tiny little pieces.

From reading, it’s my understanding, that a unique and beneficial natural chemical transformation takes place in these mustard plants when two separate chemical components, present within each plant, come into contact with each other. In this physical chopping/combining process, when the combined natural phyto-chemicals are compounded together, they become a singular natural herbicide against sprouting weed seeds. That’s why they have to be chopped up at this semi-green stage and then roto-tilled into the soil.

There are a number of other beneficial things happening to the soil from this plant’s two month life cycle, but it’s this one special unique herbicidal property of the mustard plant that I want to capture here and now in mid August.


If you notice, there is well cultivated brown garden dirt beside these fresh mustard cuttings. This dirt is also part of the same mustard patch program, but was all chopped up and was turned into the soil weeks earlier. This was done in two previous chopping and tilling sessions, in the two weeks before this activity you see here on August 15. The reason for this three week/three part chopping and tilling? I’m experimenting to determine if there’s an optimal time window that these plants release their most powerful natural phyto-herbicides. I’ll find out in September as soon as the fall rains return and the weeds try sprouting back up. By next spring, April to mid May, it will be very apparent which areas of this patch had the best anti-weed treatment by the three separate timed chopping sessions…late July through mid August.


There is much more to describe here because this entire 2,000 square foot mustard phyto-nutrified patch, will be planted with 4,500 Teasel seeds in 14 inch wide rows. This will be done in about three weeks…somewhere between the 5th to 15th of September weather dependant. I’ll explain all about that upcoming process and purpose in the next blog posts #7 #8. #9 and #10
