Composting invasive weeds

Some weeds can be composted but we have an amount of mares tail on our allotment. Do you recommend putting this in or should it be treated  differently?

    I recommend you get that infernal stuff as far away from a compost heap as possible.

    I don't put any pernicious weeds anywhere near by compost bins

    Dry it out and incinerate.
  • I have been piling up any weeds that I am not sure about in a large blue plastic tub and letting them rot down over the years. It ends up as a slurry in the bottom of the tub which then seems pretty harmless. I suppose alternatives would be to burn them when dry or carting them back for the green waste collection service.

  • Jenny that is fantastic!

    Drowning horsetail to make feed definitely kills two birds with one stone! Will have to try it out. I already make feed out of comfrey and nettles. If it works I will look on horsetail as a friend rather than a foe!

    I know @Obelixx has often mentioned using it as a preventative method for mildew. 
    Worth trying if you have a lot of it, and also have that problem.  :)

    Any thuggish weed can be composted in water to make a form of fertiliser.  nettles are full of nitrioge so good for fedding leafy plants and comfrey's roots go much deeper and pull up a broad range of nutrients which means they make a great feed for flwoering and fruiting plants such as roses and tomatoes.

    Horsetail makes a good fungicide which can beused as both prevention and treatment for peach leaf curl, mildew, various rusts and mildew:-

    1kilo fresh horsetail, bashed and bruised
    9 litres of water

    Combine the two in a plastic bucket - not metal - and leave for 2 weeks.  Stir occasionally.  It's ready when the water has gone black.  It will smell so you may want a lid.

    Strain the resulting liquid, put the goo on the compost heap and dilute the rest 1 part to 9 parts water and spray.

    On my allotment I go by the rule that anything that has lived will eventually rot down so I compost nettles, bindweed, docks e.t.c they are in a closed bin for a minimum of three years and I consider this to be enough time for the composting process to have worked, we don't have marestail.
