  • Weeds still alive under suppressant membrane

    Just a quickie, i've checked under some weed suppressant membrane we placed 9 months ago (the cheaper stuff from a home and garden store) and it hasn't exactly killed off the weeds (some are even lush green new growth growing sideways). When I checked under the expensive stuff I brought online as recommended from here , I have dead/nearly dead weeds laying there but mostly soil. As i'm wanting to grow through the cheaper stuff first with sowing from March onwards (as its shelf-life is considerably lower than the good stuff). So could I

    1) use up my compost heap now and place a no light layer over the weeds and then re-cover with the suppressant hoping they will die off in the 4-6 weeks until the frosts have gone?

    Or

    2) should I just dig out the bigger weeds as I sow and plant out in March ie dig out weeds on a Saturday, plant and sow on the Sunday?

    Or if neither of those are viable,

    3) should I dig out the weeds this weekend (or some point nearer planting time but not right on top like option 2) then re-cover the soil ready for the indoor sowing's.

    Finally, am I right in that I can't sow seeds under the membrane as they need the sun such as carrots?

    thanks in advance

    I'd slip some cardboard under the fabric and then remove the fabric, and plant through the cardboard when you are ready to plant out. Start as much as you can off in modules - it really helps to get the plants off to a good start....

    Carrots; take the cardboard off 3 weeks before you sow, dig out any weeds still there, hoe and leave for 3 weeks as a stale seed bed, hoe off any weeds that germinate and then sow.

        If you have the time, it would be an excellent idea to dig over the whole bed removing the weeds as you go. Even if they haven't rotted down, they will have been weakened and its a good time to sort them out. By digging the ground over now, you will be giving it a chance to dry out a bit and if you cover it with fleece, it will warm up ready for planting. Membrane and cardboard etc do work but they tend to provide hiding places for slugs and creepy crawlies.
