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.

I've now put down 16 beds and will put short beds accross the top at
right angles to the main batch.

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.
