How to Plant and Grow Flowers

Although plants that grow from bulbs, such as tulips and Persian lilies, are generally planted in fall, most flowering plants do best when spring-planted. Plant your plants in fertile soil that drains well and in a place where they will get the appropriate amount of sunlight.

To plant your young flowers, unpot them and tease out any encircling roots. Dig a hole that is a little deeper than the root ball and twice as wide. Throw in a shovel-full of well-rotted compost or manure, and place the plant in the center of the hole. Fill in around it with soil that has been amended with compost or manure.

Most flowering plants need watering every day or so when they are first planted until they are established, which may take around a month. After that, monitor them carefully and water if the soil is dry an inch below ground level. Mulching with an organic mulch such as bark chips means you’ll need to water less often.

If you want to give your flowers a boost, fertilize them with an all-purpose, slow-release product designed for flowering plants, following the directions on the package. Generally, you will begin to cut back on fertilizer after July so the plant can prepare for winter.
