What should I also put in the bottom of a raised garden?
The lasagna method is to fill your garden boxes with leaves, grass clippings and straw. Add a layer on top of the cardboard. Next, add your soil. The soil will eventually become rich compost.
The next question is: Is it safe to use treated lumber for raised gardens? With a few cautions, "new" pressure-treated wood can be used for raised garden frames. The most commonly used preservative for pressure treated wood up to 2003 was chromated Copper Arsenate (CCA), which is a compound that uses arsenic in its primary rot protector.

Should I put rocks in the bottom of my raised garden bed?
Because many plants require well-draining soil, placing rocks in the bottom of a raised bed to create additional drainage space below the soil is a sensible step. Unlike soil, rocks will not degrade or compact over time.
Do I need to line my raised garden bed?
You can line your raised bed to make it more durable and to prevent toxics from leaching into the soil. For lining, use landscape fabric found at garden supply stores or cloth fabric from clothing. Avoid non-porous plastic, as it can retain too much water and discourage beneficial insects and worms.
Should I put plastic under my raised garden bed?
No, I do not recommend a horizontal layer of plastic under a raised bed. As another answer suggests, I would use a few layers of newspaper to help eradicate weeds at the bottom of a raised bed, but I would not use plastic or even landscape cloth. This is where your plastic might be useful.

Proven methods for controlling weeds in your garden

- Lop off their heads.
- Mind the gaps between plants.
- Water the plants you want, not the weeds you've got.

Tomatoes, bush beans and peppers take up more space in your small garden due to the size of the grown plants, but they still work.
Can you put a raised garden bed on grass?

How long will untreated wood last in raised beds?
Type of Wood
It will warp and begin to rot within three to five years. Cedar and redwood are naturally resistant to both rot and insect infestations, which is why they're often used for decks and fences. These materials will generally last 10 to 20 years in a raised-bed garden.How deep should a raised planter be?
Make your bed as long as you like or build multiple raised beds for different crops. The depth of the bed can vary, but 6 inches of soil should be the minimum. Most garden plants need at least 6 to 12 inches for their roots, so 12 inches is ideal.

Bricks, cement blocks, and untreated lumber are all suitable for framing. Even cheap pine boards can be used to frame a bed.

Can you use treated pine for raised garden beds?
Treated pine is safe to use in gardens, but if you are worried about the old-style arsenic-treated pine, the new stuff – ACQ treated pine – is arsenic-free and becoming easier to find. One of the most popular ways to edge raised vegie garden beds is to use timber sleepers of some sort.
Is Cypress good for raised beds?
