I have recently made the difficult decision to have the large ash tree in my very small back garden removed by a tree surgeon -- who will cut the trunk down to ground level. There are raised vegetable beds in the garden, into which the roots of the tree have spread despite their thick plastic lining. I am an organic gardener and concerned that if I poison the stump of the tree, the chemical will seep into the soil (through the fine web of roots) in my vegetable beds -- but am equally mindful that the trees roots could continue to leech goodness from the soil for several years after it has been felled (the tree surgeon has advised me to cut off all shoots -- which he says will in due course kill the tree). Is there any way you can suggest to stop its growth without introducing poison to my vegetables? (The surgeon says the access to my garden is so narrow that he would not be able to introduce a machine to pull the trunk out of the soil or cut it up...)
Many thanks for your help.
