Some commercial buildings in Tallahassee always have beautiful beds of pansies or petunias from fall until spring. Annuals are easy to grow with a little soil preparation and basic care during the growing season. Some annuals perform best in summer heat while others flower vigorously only in cool weather. Frost kills warm weather annuals while heat melts out cool-loving ones. Learning which flowers grow best at the right time of year and their preference for sun or shade is the key to success.
Annual flowers love rich soil loosely dug eight or more inches deep.
Adding peat humus, compost or other organic material to the existing soil will greatly benefit their growth. They respond quickly with regular feeding using a balanced fertilizer. Watering annual flowers regularly is essential for proper growth and flowering. Water deeply and as needed. Simply water the soil at the base of the plant until it is saturated, repeating only when the soil is almost dry.
