Growing Annuals that Bloom All Summer Long
There are many different types of plants and flowers, so choosing the best ones for your garden is confusing. Should you plant perennials or annuals for long blooming color, and where is the best place to plant them? We’ll help you answer these questions and choose the perfect flowers for your yard.
What is the Difference Between Annual and Perennial Flowers?
Perennial flowers, such as the coneflower and salvia, are easy to grow because you plant them once, they grow back every year, sometimes even bigger than the year before. However, perennials generally do not bloom all summer long.
Annuals produce blooms from spring through fall and grow in many types of conditions, but they die at the end of the season and need replanting each spring.
Other flowers, such as verbena, grow either as a perennial or annual, making them an excellent choice for either type of garden.
Which Types of Annuals Have Prolific Blooms?
Many annuals, such as coleus, do not have prolific blooms, but they fill garden beds with colorful foliage. Other annuals, like alyssum, produce beautiful flowers that die back during the heat of the summer.
To fill your space with flowers that bloom from spring through fall, consider planting petunias, celosia, ageratum, and marigolds.
Where is the Best Place to Plant Blooming Annuals?
Annuals grow just about anywhere, depending on the type you choose. They grow well in containers, hanging baskets, window boxes, and flowerbeds.
There is only one crucial factor to consider when deciding where to plant them, and that is sunlight. Check the plant care tag on your annuals to determine how much light they need to thrive.
Full-sun plants require a minimum of six hours of direct sunlight daily, partial shade plants enjoy filtered light or three hours of periodic sunshine, and full shade plants cannot tolerate direct light at all.
Are Annual Flowers Hard to Maintain?
Annual flowering plants are easy to grow and need very little maintenance. The hardest part about growing these plants is planting them in the spring and watching them die back in late fall.
All they need is the right amount of sunshine and regular watering to thrive. Deadhead the flowers of annuals to encourage them to produce more blooms.
