Before adding plants, either lay the flower bag flat or prop it up at an angle.
Stuff seedlings into the holes of the flower bag. Be as gentle as possible, but you may have to be a little forceful to get the roots to fit.
Try to make sure the plant is inserted into the hole just far enough so that it doesn't stick out of the bag.
When you have finished planting all the holes, prop flower bag upright and remove the clips. Hold on to the top of the flower bag and tap the bottom gently on the ground a few times, to help settle the soil around the plants.
Check your soil level again and add more if necessary. Finish planting by adding two seedlings to the opening on the top of the flower bag. This is a good place to use your biggest plants because you won't have to squish them to fit.
