We had a redbud tree which died 3years ago. I finally got around to cutting it down and digging out the stump and as much of the roots as I could. The roots were very brittle, rotted, and crumbly as I dug them out. I want to plant a decorative cedar tree in its spot in the fall. Can I successfully plant another tree on the same location? If so, what can I do now to increase chances of success? The area is within a landscaped planted tiered area, so space is very limited. No room to locate it elsewhere. What are your suggestions? Thank you.
