what materials can i make an above ground garden with ?

Answer 1

Depends on if you are doing a flower garden or vegetable garden. You don't have to be as picky with flower gardens since you don't plan on eating what is in them... if it's a vegetable garden the frames can be made from almost any material except treated wood (or treated landscape timbers) and/or cresote treated R/R cross ties, which have toxic chemicals that might leach into the soil. Either use a non-treated wood that weathers well, like cedar or redwood, or use some form of stone or concrete.

Check out the website below... there are tons of tips and tricks on it that will help you get started.

Good luck!

Answer 2

I used pressure treated 4x4's in the corners and screwed PT 2x12's to them. Works great!! BTW, the amount of "toxic chemicals" that "might" leach into the soil from treated lumber is so minute that it's of no consequence. If it's really that big of a concern, the insides of the raised bed can be lined with plastic sheeting. I'm thinking about how much fun it would be to replace the cedar or redwood lumber in your raised bed when they rot, and if they're not treated, they will still rot. Even if you're in a dry limate, I wouldn't give them more than 2-3 years when they will be holding back moist garden soil.

Answer 3

Do you mean like a raised planting bed?

I ended up using cedar pickets that were meant for a cedar fence, to create a raised bed about 5" tall. They were pretty inexpensive, and I was told that the cedar would hold up well to being in contact with the ground.

I also used 2x2 cedar pickets as supports at the corners of the bed and midway down each side.

It's my first shot at building a raised bed, so we'll see how it goes!! =)

Answer 4

Most people use landscape timbers to frame the garden. Then fill with the dirt of your choice. You could also use brick or concrete block but this would be much more expensive.

Answer 5

You could use railroad ties to contain topsoil and put the garden inside the railroad ties.

Cheap and easy!

Answer 6

Railroad ties, pressure treated lumber, large stones
