Transplant to raise bed

I was thinking of transplanting my strawberry cheesecake photo to my raised bed. I already have two plants on each end about 4 x 12 raised bed garden all organic self-sufficient garden. I think I can support a third plant but I’m no expert and this is my first organic run. Any insight on adding a third plant or is that just gonna be too much and I should keep it potted. They are 100days young. I’m in 5 gallon pot now I transplanted 3 of my others into 10 gallons pots.
