4-8 yrs in organic mix with little PWT issues
Today I repotted blueberry that had been 8 yrs without repotting and a pluot that had 4 growing seasons in an organic mix.
This is the pluot that had grown enough roots to split the pot. Most of the roots were on the outer edge of the rootball.
The blueberry which yielded 15-18 lbs last year had roots much more evenly throughout the rootball.
There were no serious indications of issues with PWT although the blueberry did have fewer roots in the bottom than the top of the rootball. This is blueberry roots right above the bottom screen.
