Can bokashi tea be used as a weed killer?

Absolutely! Bokashi tea is very acidic. Dilute bokashi tea 1:100 for use as a fertilizer (and diluted even further for particularly sensitive plants). This acidity makes it ideal as a weed killer. No need to dilute it, just simply pour it directly on to your weeds. This is a great, natural herbicide that won’t have any negative health effects, unlike other weed killers. For example, Roundup may cause cancer in humans who are exposed to it so if you have ever used it then you could want to read more about this here.

How to use bokashi tea as a weed killer

Using bokashi tea as a weed killer could not be simpler.

  1. Firstly, locate your weed
  2. Then collect bokashi tea from your bokashi composter
  3. Next, pour the bokashi tea on the weed
  4. Repeat every few days if your weed is a particularly stubborn one (buttercups, dandelions etc).

By pouring the bokashi tea directly onto the plant, it will also soak into the soil and get to work on the roots of the plant. However, it could also kill adjacent plants. If there are neighboring plants that you don’t want to lose. Put the bokashi tea in a spray bottle and apply the undiluted bokashi tea to the foliage of the leaves only.

    Can the undiluted Bokashi tea be used to kill moss on an asphalt roof that gets no sun? And if so, shall I wait until it turns green with the winter rains, as it just dehydrates and ‘rests’ in our arid summers in the PNW.

      Theoretically, yes, undiluted bokashi tea could be used to kill the moss. However, this would take a lot of bokashi tea and you may be better off removing the moss when it is dried in the summer.
