Caring for Annuals. Annuals are fairly easy to care for. If you plant them properly at the right time, annuals will have no problems surviving the season. Make sure to plant your annuals after the chances of frost have diminished and to water them only when they are newly planted.

Growing Giant Sunflowers. Sunflowers are a bright and easy to grow plant. Depending on the variety, they grow from 18 inches to 15 feet tall. Plant sunflowers after the last frost. Choose the one you want and plant it in a bright area. Make sure to water it until it sprouts, and give it plenty of room to grow. Soon you will have big, beautiful sunflowers that will brighten your day while growing and leave behind a great snack once it dies.
