Could someone please tell me the best thing to cover the area with whilst I am working on other parts of the allotment. If I can help it I do not want to use any weed killers. I have read covering over is one of the better solutions. My two thoughts of covers are a think black plastic polythene sheet Something like : ('HEAVY DUTY BLACK POLYTHENE PLASTIC SHEETING 4M WIDE DPM ROLLS 300MU 1200 GAUGE | eBay' (http://tinyurl.com/nr4csbh)) With option two being heavy duty garden control fabric. Something like : ('Kenley Garden Landscape Weed Control Fabric Ground Cover - Heavy Duty 100GSM | eBay' (http://tinyurl.com/lewfp78)) Does anyone have any preference over these two options or am I missing something better on the market. Depends on you budget. The cheapest option is to go to a carpet retailer and ask them for a bit of rubbish carpet, then place that over. The trouble with the black polythene, especially the thin variety is that winds will soon wreck it. Carpet is also better as it allows water through But the OP should be made aware that carpets also contains chemicals that rainwater will leach out of it. Couch grass will happily grow through a carpet anyway so you can't win. Glyphosate based weedkiller is probably the most environmentally friendly way to zap couch grass. Grass is exquisitely sensitive to glyphosate so it works very well (although not at this time of year - it has to be growing). A hit and then when it is tinder dry a flash fire of the dry material leaves a blackened area where new green growth it easy to spot weed. Irrational fear of "chemicals" is getting to be a problem. -- Regards, Martin Brown |
