Growing flowers in plastic bags is an easy way to enjoy your flowers and extremely inexpensive. Keeping your plastic grocery bags, will enable you to have plenty of planting containers for your flowers. Not only are you helping the environment by reusing bags, but the bags will enable you to move your flowers to a different location, constantly changing the beauty and landscape of your garden. To successfully grow flowers in plastic bags, some preparation is required.
Select a bag to grow your flowers in. Make sure the bag has no large holes or tears that will allow a lot of the soil to fall through.
Use scissors to cut several small holes in the bottom of the plastic bag for water drainage. Generally, 7 to 10 holes is enough.
Fill the plastic bag with potting soil. Leave approximately 3 to 5 inches of bag above the surface of the potting soil.
Create a hole in the potting soil that is twice as deep as your plant's root ball. Place the young flower(s) into the holes created in the potting soil, and completely cover the roots.
Sprinkle a time-released fertilizer into the bag, according to the fertilizer's package directions. Use your fingers to lightly mix the fertilizer into the potting soil around the plants.
Water the flowers until the soil in the plastic bag is moist throughout. Insert your finger into the soil, and keep adding water until the soil is moist as far down as your finger can reach. The plastic bag will hold moisture easily, so frequent watering will not be necessary after the first week. Allow the soil to dry out slightly in between watering sessions.
Place the plastic bags that contain your flowers in an area that receives the proper amount of sunlight for your flowers' needs.
