Annuals are garden plants that grow and bloom for a single season. These plants are perfect for adding life to gardens and outdoor spaces and are often used in containers, borders, and hanging baskets. They are also popular with gardeners who want to experiment with different combinations of colors and textures in their gardens. In the Upstate of South Carolina, because there are two distinct seasons, we offer both Spring/Summer Annuals discussed here, and Fall/Winter Annuals on the linked page. Also, be sure to check out our guide for Preventing & Prosecuting Common Spring Pests.

In addition to these spring annuals, we also sell a multitude of grasses and colorful foliage that provide annual pops of color and texture. Don’t forget that our Fall & Winter annuals also provide important information.
All blooming annuals are heavy feeders; you must fertilize often. We recommend Fertilome Garden Cote 6, which provides a slow-release six-month feed. Also, occasionally supplement with a high-phosphorous fertilizer such as Jack’s Blossom Booster for more blooms. To keep your hanging baskets fresh and prevent legginess, pinch one leg from each trailing cultivar back to the edge of your basket once per week. For upright varieties, pinch as needed to promote branching or to reduce size.
More About Annuals
One of the benefits of planting Annuals is that they are often fast-growing and will bloom quickly, adding instant color and vibrancy to gardens and outdoor spaces. They are also relatively easy to grow and care for, making them an ideal choice for beginners and experienced gardeners alike. However, once Annuals have completed their life cycle, they will die off, and the gardener will need to replant them the following season. In the Upstate, we have a spring/summer season and a fall/winter season. The spring/summer season annuals are planted after the last frost date in the spring, and the fall/winter season annuals are planted to replace spring season annuals after first frost causes die off or after they become exhausted after an entire blooming season.
Annuals are heavy feeders and require regular fertilization to keep vigorous blooming. Martin Garden Center recommends three approaches a 6-month slow-release feed provided by Fertilome Garden Cote 6 for lazy people, the Fertilome Premium Bedding Plant Food every 30 days, or Jack’s Blossom Booster plant food every or every other time you water. Sometimes, a combination approach works best.
Annuals come in a wide range of colors, sizes, and shapes, making them perfect for creating a variety of garden designs. We prescribe the Thriller, Filler, Spiller approach to containers at Martin Garden Center. Often, the thriller, filler, and spiller provide the texture to make stunning mixes in containers. Annual plants can be grown in various containers, from traditional pots and urns to hanging baskets and window boxes. They are a great way to add color and interest to small spaces, balconies, and patios.
However, it is important to note that while annuals are relatively easy to grow, they have some limitations. Because they only last for one season, they may not be the most cost-effective option for gardening on a budget. Additionally, some varieties of annuals require more care and attention than others, so it is important to do your research before choosing which plants to grow.
