How to Plant Flowers

For most flowers, the best time to plant is spring or early fall. Place your plant carefully according to the amount of sun it needs, and plant in fertile, well-drained soil. 

Unpot your new plant and tease out any encircling roots, which can eventually girdle and kill the plant if left as they are. Dig a hole that is a little deeper than the root ball and twice as wide. Throw in a few handfuls of well-rotted compost or manure. 

Place the plant in the hole so that it is at the same level as it was in the pot. Fill in around it with soil that has been mixed with compost or manure. Tamp down the soil. Don’t fertilize immediately, but give your plant time to adjust to its new home. Do water it thoroughly, though. 

Your new plant will need daily watering for a few weeks while it acclimates to its location. After that, you should only need to water it when the soil feels dry. Most plants manage nicely with about one inch of water a week. Mulching around the plant with an organic mulch such as bark chips can keep watering to a minimum.

Once established, you can give your plant a boost with an all-purpose, slow-release balanced fertilizer. Follow package directions, and water in the product after spreading it around the plant.
