How to Plant and Grow Flowers

Choose a site for your flowering plant that gives it adequate sunlight. Most flowering plants prefer fertile soil that drains well so they are never standing in a puddle. Be sure to allow space between the plants, so they can reach their mature size without crowding.

If you are planting nursery stock, unpot the plant and tease out any roots encircling the root ball so they cannot girdle the plant and eventually kill it. Dig a hole that’s a little deeper than the root ball and twice as wide. Add a few handfuls of well-rotted compost or manure to the hole and place the plant in it so it’s at the same level as it was in the pot. Fill in around it with loose soil. Tamp down and water thoroughly. 

When newly planted, your flower will need water every day or so. Once it is established and growing, it will be fine with roughly an inch of water a week, either from rain or supplemental watering. Add an organic mulch around the base of the plant to help the soil stay moist and keep weeds from growing.

Fertilize your plant early in the growing season with a general-purpose, slow-release fertilizer, following the package directions. Ease up on fertilizing by mid-July, so the plant can begin to prepare for winter.
