Good points. Once the plants grow out, there might be less room between the beds. Also, I might not always be the only one working the garden beds.
Is there any "minimum" working distance between garden beds that is recommended?
One other option that I have considered is just butting the half-sized bed up alongside and touching the full-sized bed. That would still leave 3+ feet between the garden beds plus it would still increase the garden beds in the same space. Some beds would now just be 4X6 feet if I moved the half-sized beds right alongside the existing beds.
Seems like most are 3-4 ft apart.
Could make a keyhole by turning it 90 degrees.
