Thanks to the EU banning more chemicals I can no longer use a pre
emergent herbicide on the dahlias so I have had to switch to a ground cover / mulch fabric, This comes in a 100m roll 1.4 m wide and has to be layed by hand. http://i240.photobucket.com/albums/f...undcover02.jpg I've now put down 16 beds and will put short beds accross the top at right angles to the main batch. http://i240.photobucket.com/albums/f...undcover03.jpg All I have planted so far are my "Tree dahlias" 78 of them. The main batch of dahlias will be planted through the mulch which will have to be lifted to lift the tubers in the Autumn, I will also be doing a 1000 or so pot tubers (I Hope) and another 800 seedling dahlias also in post which will be planted through the sheeting but which should lift leaving the sheet in place for next year.

What about Basamid or Dazomet to sterilise the soil, kills weeds and pathogens too. Might be expensive although one of our allotment holders uses it. -- Regards Bob Hobden W.of London. UK |

David Hill I don't know if it would be possible, but could you plant your dahlias in (large) water-lily containers - those things which are open-weave plastic baskets? If they were planted at ground level, could you not attach binder string (or something similar) and just lift them through an X cut in the membrane before winter? It's too late now, but if it worked you could save time by just using a square metre of fabric above each basket, rather than lay out whole rolls and plant through them. Of course, all this would depend on the dahlias not being able to form tubers outside the basket. Whatever, it seems you're in for a lot of work thanks to the EC zealots. -- Jeff |

Basamid or Dazomet to sterilise the soil, is one thing I had thouht about, BUT We have a high rainfall and I am dealing with a site of around half an acre. You need to rotovate the ground well, then apply the chemical and rotovate it in, cover the ground with polythene for 7 to 10 days, then remove the cover and rotovate again to get the fumes etc out of the soil. With our rainfall, and on sloping ground this could give rise to a few problems, including runoff or heavy rain from that area, holding the sheet down etc. Pot growing the dahlias in large containers would be a problem as we have a heavyish loam and plants wont pull out without digging, also the cost of up to 5000 pots would be much more than the cost of the sheeting. The problem with using squares of fabric would be weed growth between each square, and the wind blowing the sides up unless you hold each side down with soil or pins or something. It would be possible to grow all the dahlias in large pots, say 12 to 15 inch and stake them, letting the roots grow through into the ground, but the cost of pots and compost would be excessive. OK if you were growing a dozen or so, but not in my numbers. David |
