getting rid of suckers
I have a rhodo on the side of my house that must have been, at one point, about 7 feet wide out from the house. It has been trimmed back over the years by former owners then I pruned the bottom up to about 3 feet from the ground to make it more tree-like.
The problem is the shallow roots still extend to about 7 feet from the house and produce suckers along the root. I have since cut some of these out then stopped not knowing if I was killing the main trunk and branches.
See, I'd like to plant something in the bed around this rhodo but will ahve trouble with these shallow roots and suckers.
Can I dig these up an cut them out? Is the main root system deeper and under the main trunk?
Please help with some advice... Thanks!
