Encouraging rowan tree (sheerwater seedling) growth after a trauma!!
Hi -hopefully you can offer some advice-I have planted some rowan trees ( sheerwater seedling variety ).They were slightly damaged by a strimmer.(around base of trees).I cut out any damage and applied a commercial sealant.I have since learned sealant may not have been the best way to help the tree heal.(It is now considered an old fashioned treatment apparently)As it cannot be undone without causing further damage -has anyone any tips on encouraging growth /recovery in these trees. The soil type is slightly acidic and of good quality and they were surrounded with mulch to aid that peaty base they seem to prefer.Any ideas ? (Some apple and pear trees affected and treated with this method also). I would welcome any constructive ideas -thank you.
