Garden plot over old parking lot.

Huh, I thought this forum would be more active, anyways... If someone wants to suggest another forum for me to put this under, give me a shout out please!

I have a plot in my local community garden. It's my second year and I have learned that 2 feet below the soil is an old parking lot. I never saw any soggy areas, drainage is not a concern here. However, this does create a slight problem for me in my trellis construction.

The plot itself is approximately 10' by 10'. I would like to put up a sturdy trellis over at least half of the perimeter for 2 tomato and 2 cucumbers, in addition to some lighter weight snow peas and pole beans. I'm concerned about the integrity of the trellis if I only have a maximum of 2 feet to anchor it in.

We do get some pretty severe wind gusts, and I can just see a lightweight trellis sailing across the community garden. I feel like if I can find an entire piece, and bend it at the correct spot for my corners, it would give it a lot of stability. I'm not sure what material would even bend at a 90-degree angle.

Any material suggestions or structural tips from anybody? Pictures, anecdotes, other places to ask are all welcome!

Most people are suggesting that you drive 24" of rebar into the ground and then slip conduit over about 24" of exposed rebar. If you take a 48" length of rebar and drive down 24" you should get a fairly stable dowel to anchor your trellis.

Have you dug down to verify the depth to the supposed parking lot? What pavement material was used? If the parking lot was paved with asphalt, you can probably pound rebar through and get a very stable trellis anchor. If it is concrete, you will need to drill through or bust out the concrete in the area you want the trellis anchored.

Hope this helps.

Couldn't agree more..
