Watering: Do not neglect to water your plants. Bedding plants are best watered with a handheld hose or with a microirrigation system. Both allow water to be directed to the soil and roots without wetting the flowers.
Weed Control: Weeds can be suppressed by mulching. The amount of mulch to apply depends on the texture and density of the mulch. Mulching materials should not come in contact with plant stems. The high moisture environment created by mulch increases the chances of stem rot, which can result in plant death.
Fertilizing: Make sure that annuals receive nutrients throughout their growing season. Controlled-release fertilizers provide an extended, steady supply of nutrients. Fertilizers that are not controlled release should be applied monthly according to the label's directions.
Pruning: Many annuals perform best when they are pinched and deadheaded. Pinching is just light pruning of stem tips to control the size and shape of the plant. Deadheading is the removal of spent blooms to improve appearance and redirect plant energy into new growth and flowers rather than seed production.
