Hi all

Went to dig over the soil in the ghouse bed today and it is almost completly full of fine fibrous roots. I guess they are sprouting from tree roots that I cut through when the house was erected last year.

The Ghouse is only 6ft from a laurel hedge (20ft tall) so I think the roots are probably from that.

I dont think the compost will support these roots and the veggies so I think I am going to have to empty the beds out and try to put down some sort of membrane but I don't want to end up with a marsh when the water can't drain away.

I wonder if anyone has ever experienced this and can offer any advice at all?

Thankyou very much

Fed up of Salisbury!

Hi David,
What really needs doing is to dig a trench between the Laurel Hedge and the greenhouse and cut all the Laurel roots off. When you have done this insert a vertical Heavy Duty Black Polythene membrane and back fill. The new roots from the Laurel will hit the Polythene and be deflected and you should then be trouble free for a great number of years.
