Flowering plants require different care than that of vegetables and fruits. If flowers are not cared for properly, the plant will not bloom and the colors will look dull. Flowers wilt quickly without the right fertilizer application. They're hungry plants. Flower care varies as wildly as the flower varieties do.
New flowers that are grown in a pot require a well-draining soil material. Texas A&M University recommends a combination of peat moss, perlite, sand and soil. Prepared potting materials are also available from garden centers. Garden soils should have a pH between 5.5 and 7.0 for most flowers and have a good organic material content.
Most flowers require a nighttime temperature between 65 and 70 degrees Fahrenheit, with a daytime temperature about 10 degrees warmer, says the University of Missouri Extension. Flowers require planting at the correct time in spring to prevent cold damage, and to prevent heat from damaging immature flowers. Check the specific variety you have and its requirements.
Many flowering plants are grown from bulbs, which need different care. Soil requires the addition of organic content such as peat moss worked into the top 12 to 18 inches of soil, says the University of Illinois. Bulbs are best planted in an area that provides the correct light requirements for the variety. Shady areas are avoided in most cases. The flower garden is never placed by trees or shrubs whose roots may compete for resources, or dislocate flowers from their habitat. Bulb are usually started indoors during the winter by chilling them in the refrigerator to force the bulbs to sprout.
Flowers require fertilization at the time of planting, as determined by a soil test. Soil test are available through university extension services and are also available at garden centers. Fertilizers are added again six to eight weeks after planting for most flowers. Flower-specific fertilizer is available from garden centers. Complete, water-soluble fertilizers are commonly used with flowers.
Flowering plants require different amounts of moisture according to their variety, but for general purposes the soil should be moist to the touch and never be allowed to dry completely. Some desert flowers do require a drying out before watering, though, so check your variety for specifics. Flowers require watering in the morning before bright sunlight to prevent water from scorching flower pedals. Watering at night is not encouraged because the soil stays wet for too long.
