Bay Tree - are its roots poisonous to other plants?
We have a 10 foot bay tree made up of 5 stems which suckers like nobody's business. I hoped to underplant the bare earth beneath it - good light, sheltered, dulcet Cornish air - but anything I put in there either fails to make any growth or just dies. If I move the plants that are poorly to a different bed they seem to take off in about a week or ten days. Is it possible that the roots are poisoning the soil? Is it anything to do with the white substance that the roots are covered with?
Thanks for any guidance!
