How to Grow Annual Flowers

Overview

Planting and growing annual flowers is a rewarding experience for all gardeners, from the novice to the experienced. Annuals do need to be replanted every spring, typically from seed, but because annuals follow a predictable lifespan of just one season, a gardener knows what to expect from them. Annual plants such as petunia or marigold are rewarding because they will produce flowers throughout their entire lifespan from spring until fall.

Step 1

Choose which annual flower seeds you want to plant, based on color, size and overall design of your garden space. Popular annuals include petunias, sunflowers, impatiens and marigolds. All are available in seed form to plant in the spring.

Step 2

Prepare the planting bed by fluffing up the top layer of soil, adding soil from another location or purchasing garden soil by the bag. The soil should be light and easily manipulated by hand and your garden tool.

Step 3

Follow the manufacturer's instructions on spacing and depth of placement of the annual seeds. Depending on the size of the fully grown annual your spacing will be different based on the variety you choose.

Step 4

Cover the annual seeds with a layer of soil; this protects the seeds from the weather, and keeps pests and birds from disrupting the germination period.

Step 5

Water the newly planted flower seeds regularly for the first two weeks, after the initial two weeks water as needed.

Tips and Warnings

  • Plant annual seeds after the first frost has passed; the soil should be pliable and warm to the touch. Be aware of seed planting and spacing. You should expect a plant where you place a seed; planning your design and overall look are crucial with annuals.
