Grow bags are bags in which someone can grow plants. The gardening trend is growing; even apartment dwellers and people without yards big enough to put a garden want to grow flowers or food. The size of grow bags varies; the correct size depends on what a person plans to grow, where the bag will be placed or hung and how many grow bags a person wants to place in one area.

Skill level:

Things you need

    Open-top bags

  1. 1

    Choose a bag size to fit the type and number of plants you plan to grow. Make sure the bag is heavy enough to withstand the weight of potting soil. Place one bag inside another for extra stability if necessary.

  2. 2

    Set the bag where you intend to grow the plants, particularly if the bag is large and will be heavy once filled with soil and plants. Place a piece of cardboard under the bag to help slide it if you wish to move it after filling and planting.

  3. 3

    Fill the bag to within a few inches of the top. Spread the soil as you work, so the bag is filled solidly from side to side. Tuck the leftover edges of plastic toward the inside of the bag in the soil.

  4. 4

    Plant seeds or plant sets in the soil. Follow the seed or plant package suggestions on how far apart and how deep to plant each item.

    Hanging Grow Bags

  1. 1

    Decide where and how you wish to hang a bag before choosing the size and shape of a bag. Choose a long, thin rectangular bag for an oblong hanging bag effect. Consider smaller bags that will be lighter when filled for most hanging plants.

  2. 2

    Cut slits in the bag after filling it with soil. Place slits where you wish to have a plant growing on the outside of the bag.

  3. 3

    Place seeds or plant sets into the soil inside each slit in the bag. Push them firmly downward toward the inside of the plastic to provide a better hold when the plants grow.

  4. 4

    Hang a planted bag on a nail or hook. Place a bag inside a macrame hanger, if desired.

Tips and warnings

  • Consider using planting moss instead of soil for a lighter grow bag.
  • Make decorative grow bags. Place a heavy plastic bag inside a large fabric or plastic beach-style bag. Fold the plastic inside just below the level of the bag's top before or after filling the bag with dirt.
  • Turn a bag of soil into its own grow bag. Lay the bag flat on the surface where you plan to keep it. Cut out a large portion of the topside of the flat bag. Place seeds or plants in the soil right in the original bag.
  • Use burlap bags instead of plastic to provide a different look, as well as a good source of drainage for an outside bag.
  • Poke a few drainage holes in an outdoor bag, if desired. Do not have drainage holes for grow bags that will be used indoors.
