Do large planter boxes need drainage?

Do large planter boxes need drainage?

Yes. Planter boxes need very good drainage holes at the bottom of the container. Any water that stagnates will choke out the oxygen that is channeled to the roots.

What is a good width for a planter box?

Width – Planter boxes 1.5 to 2 feet wide provide space to grow vegetables in a small footprint. Narrow planters work well along a railing or fence, and as garden privacy screens, with matching trellises. Wide planters provide space to accommodate larger plants, even small trees, if you have the room.

How long should planter boxes be?

A minimum of 8 inches in depth and 8 inches from front to back is required to have enough room for a selection of plants. Larger–say a foot in depth and width–is even better, particularly if you want to include a lot of plants and want them to fill out enough to overflow the box.

How much would it cost to build a garden box?

Should a planter box have a bottom?

No bottom is required if your raised garden bed is sitting on the ground. Even though you don’t need to put a hard bottom on your raised garden beds in most cases, you can still use weed fabric to prevent weed seeds from germinating in your soil. Weed fabric works in much the same way that cardboard works.

What is the best depth for a planter box?

6-to 8-inch
For most plants, a 6-to 8-inch-deep planter box is sufficient. The depth may vary for some vegetables, however. Turnips, cucumbers, broccoli, beets, lettuce and green onions can all grow well in a planter box at that depth, but other vegetables, like cabbage, need a deeper depth of at least 10 inches.

Should I put rocks in the bottom of my raised garden bed?

You should avoid putting rocks or gravel at the bottom of your raised garden beds, or any of your planters or containers for that matter. With your buried rock layer trapping water beneath your soil, problems with fungal growths and root rot are more likely to occur.
