There should not be a problem with dividing your garden area into two, or even four or eight, sections. You will obviously have less planting area with additional walk paths. There should also not be a problem if you need to cut your existing PT wood frames. The main consideration is to wear good respiratory and eye protection if cutting the pressure treated (PT) wood. Perhaps that is why you were told it was "hard to work with" once installed.

Never though about having four sections -that would be nice to! Thanks so much cuestaroble! :)

I don't know how you manage to reach the center in a plot that big. Dividing it somehow is a good idea. An alternative to separations with paths you could put stepping stones at random to allow you to reach all areas of the plot

The key to raised bed gardens is that you never step or lean, or kneel on the soil.

As such, the average reach of a gardener is 2 feet.

Therefore, your raised bed garden can be no wider than 2 feet, if it up against a fence, house or some other insurmountable object. If you can access both sides, then it can be 4 feet wide.

You also need to maximize the square footage of gardenable soil, so keep the trails as small as possible.

I would suggest that you draw out several possible scenarios, dedicating as much growing space, and as little trail, as possible.

Thanks guys for the feedback!

Yeah, my dh and his friend made this for me one day as a surprise, which nether know anything about gardening. It is very difficult crawling in and out. The trellis is for the cold winds. It gets extremely windy where I am, and tends to wind-burn my plants. I guess I can invest in some high-quality hoops as well and remove the trellis.

Cheers!!!
