Postmortem: what happen 4n1 cherry tree?
It's a 4n1 cherry tree in 7 gallon pot from home depot. Planted in 20-inch terra cotta pot with standard off-shelf potting mix. Bud break fine with only 2 flowers, all the sudden leaves turn yellow and wilt. Dig it out take picture of the root system. Noticed it never break out the original root shape.
1. Is this phytophthora root rot?
2. did i water too much?
3. any suggestion if I try again?
Thanks in advance
