What makes the most sense for growing vegetables (tomatoes/peppers/squash/etc) in a new, small 6ftx9ft greenhouse in a hardiness zone of 6?
Removing the grass inside and then...
- Planting plants at ground level, simply replacing the first 8 inches or so of soil.
- Filling the greenhouse base with 8 inches or so of raised soil (not a problem for wood base).
- Replacing the soil with something like rocks/bricks/mulch and keeping plants in pots.
- Some hybrid thereof?
What the the pros/cons of each?
It would seem to me that most people go with #3 for some reason. I don't see many people choosing #1, I wonder why... it seems easy and provides lots of surface area to grow in. #2 is a good as #1 but provides extra drainage.
