A good 3 year old buck
I accidentally top killed an orient pear a couple years ago. It came back from the root the next year and I thinned the suckers to one and grafted onto it. Well the graft did great and the pear has put on about 4.5' of growth since I grafted it last year. My problem is the roots just continue to sucker which makes spraying nearly impossible. I have been cutting them off below ground level ever since but the next month there seem to be twice as many. How do I stop this. Could I use plastic or cardboard to suppress the shoots? What are you guys' thoughts.
