Both pots were started at the same time from the same batch of strawberry starts. They should have the same soil box. Both grew vigorously last spring/summer and got visited by deer in the fall. Both bounced back pretty well before winter set in. The left pot is very happy, the right... Not so much. I do recall the big pot having quite a bit of wilted leaf cover all winter, but don't think that was the case for the pot on the right. Maybe I didn't notice a late in the season deer visit that set the small pot back? Maybe the smaller pot got just enough colder than the big pot to kill some roots? Any other theories?
Have you moved them recently? Could be they just aren't getting the same sun
Nope, they've both been in the same spot for the past year or so. The bigger pot does get a touch more sun, but they were both doing great last year.
