I line my raised beds with two layers of good quality landscape fabric to keep the planting medium from escaping. I like the Preen brand available at Sam's club. The landscape fabric also serves to prevent weeds and roots from finding their way into the bed from underneath.
For the deeper of my raised beds I added sticks and twigs that had fallen in the yard, plus some pine cones and Spanish moss before I added any planting medium.
anthocar said:Hello, I have built raised garden beds in my backyard. They are about 24 inches high (pretty tall). I need to fill the first 6 inches with something lightweight that won't put a lot of pressure on the bottom of the beds over time. The boxes are built out of cedar fence pickets. The recommended fill depth for the soil I am getting is 18 inches max, after which the soil risks becoming anaerobic. I live in Austin, TX.
Question :1 - Should I line the inside of the garden box with anything to keep the dirt inside the boxes + keep moisture in? If so, what should I use?
Question 2: What should I fill the first 6 inches with? Leaves and twigs? Scrap wood? I have some fill dirt that I can use, but I'm worried that it will crack the garden beds over time.
Thanks in advance :)
I personally would worry a lot less about drainage, and more about keeping the soil moist.
In the deep south, with little rain, keeping containers from drying completely out, and unable to absorb moisture.... It's a big deal.
I totally wouldn't worry about that either... One of those problems of gumbo clay and constant rainfall....
planning to fill those things with gumbo?
How wide are those boxes?
I think Ida built them twice as wide....
more room for veggies, and easier to keep watered.
As far as what to put in the bottom?
I'm with the people that want you to add material that will feed the plants.... Either the limbs and leaves idea or just regular soil.
If you are worried about the bottoms blowing out.... Maybe reinforce them with 2 x 4s or whatever, and decking screws.
Personally, I wouldn't worry about that.
You can always replace the bottom boards later.... Or not.... The box will still work after the bottom boards bust loose.... I useta make raised beds with no supporting materials... Just the clay....
stone said:Nor was I talking about boards under the soil....
Bottom boards = boards across the bottom of the wall.
Cedar shouldn't be attractive to termites.
Stinky rotted wood.... I've seen stinky wood in anaerobic conditions....
Rotted wood buried in the soil..... Really shouldn't be stinky.... And even if it were, it's buried... Who's gonna smell it?
So.... You didn't answer the question about width. You said they were 2 ft tall, but nuthin about width.....

Thanks for the input about the stinky wood. With regard to termites, the wood I brought home turned out to be oak, not pecan. The beds themselves are cedar and I'mglad termites don't like Cedar. Even if I have or get termites in the oak, will they eat veggies?
