How and Where to Grow Annual Flowers in Your Garden

Annual flowers are a popular choice for gardeners because they provide a burst of color that lasts the entire growing season. While annuals require more work than perennials, they are well worth the effort.

Keep reading to learn how and where to grow annuals in your garden.

Full sun

Annuals need at least six hours of direct sunlight each day in order to thrive. If you want your annuals to flower abundantly, choose a location in your garden that receives full sun throughout the day.

Partial shade

While annuals need some sunlight in order to grow, too much sun can cause them to wilt and fade quickly. If you live in an area with very hot summers, choose a location for your annuals that receives some afternoon shade so that they can stay cool and hydrated.

Rich, well-drained soil

Annuals need rich, nutrient-dense soil in order to grow and thrive. Amend your soil with compost or manure before planting annuals to ensure that they have the nutrients they need to grow strong and produce plenty of flowers.

You should also make sure that your soil drains well. Standing water can quickly kill annual plants.


Mulch helps keep the roots of annual plants cool and moist during hot summer days. It also helps prevent weeds from competing with your flowers for moisture and nutrients. Apply a 2-3 inch layer of mulch around your annual plants after they have been planted and water regularly.

Fertilize regularly

Annual plants are heavy feeders and will need to be fertilized every two weeks during the growing season in order to bloom their best. Use a water-soluble fertilizer designed for flowering plants and be sure to follow the instructions on the package carefully so that you do not over-fertilize and damage your plants.


Annual flowers are a great way to add color to your garden from spring through fall. By following these simple tips, you can successfully grow annual flowers in your garden all season long.
