Do annuals have deep roots?
Annuals are hungry (and thirsty). Annuals are also thirsty because they aren’t blessed with a deep root system so even water-conscious annuals bloom better with regular water. Tip: When the soil feels dry about one inch below the surface, it’s time for a drink (the plant, not you).
What are the characteristics of annuals?
Characteristics of Annuals As the name indicates, an annual is a flower or plant that lives only one year or season.

When should I remove annuals from my garden?
Another good idea is to remove annual flowers after a killing frost. In addition, perennials that show signs of disease should be cut back in the fall. Healthy perennials can be cut back in the fall or spring. Perennials that provide winter interest, such as ornamental grasses, should be cut back in early spring.

All roots, stems and leaves of the plant die annually. Only the dormant seed bridges the gap between one generation and the next. Perennials – Plants that persist for many growing seasons.
