Your Winter Flowers Do Not Like The Florida Heat!

Well it's Monday again..time sure does fly by! Has anyone else noticed that good ole' Florida skipped Spring and plummeted straight into summer?! With the swift change from cool to hot our landscaping isn't happy. Many of you had flowers planted in the fall to beautify your yards. With summer upon us those flowers are going to start to die off. This die off isn't due to poor landscaping procedures, but rather the intense heat. Many of the plants planted in the fall can NOT withstand the summer heat. For this reason we highly recommend replacing your flowers every 6 months. In the fall and summer, no matter how much we water and fertilize there is no saving winter plants during the heat of summer. See below an excerpt I found from University of Florida better explaining this dilemma.

Key words. annuals, bedding plants, blooming plants

Low-growing plants with showy blooms are used to add a splash of color to an entrance way, walkway, porch, deck or patio. They provide high impact when used as mass plantings in raised or in-ground beds. These plants can also be grown in containers or fit into any garden or landscape. The plants covered in this publication can be grown in all of Florida and in many parts of the world. However, this publication is written from a South Florida perspective. Climate, soil, insect, disease and nematode pressures will invariably differ from region to region. These differences will determine the best plants for your growing conditions.


Plant in color beds can be classified as either annuals, biennials or perennials. Annuals are most frequently used as bedding plants*. Annuals are plants that germinate, flower, seed, and die in one growing season (not one year). In South Florida, there are two distinct growing seasons; a warm season lasting from May through October and a cool season lasting from November through April. Some annuals are adapted to growing in the warm season, others in the cool season and still others have the capability to grow all year. Annuals with a restricted growing season do poorly when grown outside their season and usually are removed from the garden because of natural decline. Annuals are temporary seasonal colors and should be replaced every 3 to 6 months even if it’s a type capable of weathering both the warm and cool seasons. Perennial plants for the color beds last for three or more years. However, some perennials may not be adapted for sustained growth in South Florida and are therefore best used as seasonal annuals. This is due to our intense disease and insect pressures, and high seasonal heat and humidity. Most bedding plants are utilized for their showy flowers. However, there are a minority that are used for their colorful and attractive foliage or fruits (Table 4.)

When to Plant

In South Florida, annuals that grow well in the cool season should be planted in the fall, winter, or early spring. Annuals that can tolerate high temperatures and humidity should be planted in late Spring or early Summer. Some bedding plants such as wax begonias, crown of thorns, and pentas may be planted year-round. Still others, such as gerbera daisy, periwinkle and zinnia, will perform year-round but are best planted before the rainy season. This allows them to become well established and more disease resistant before summer heat and rainfall begins.

Where to Plant

All plants in the color beds should be planted so that they receive the correct amount of sun and irrigation. Most “sun loving” bedding plants grown during the summer in South Florida do best when they are shaded from the harsh afternoon sun.

Fertilization, Irrigation and Grooming

Garden soils, especially in recently developed areas, are frequently infertile. Flower beds should be fertilized with a controlled release fertilizer such as Osmocote, Dynamite or other product. Controlled release fertilizers are ideal for Florida’s sandy soils. Controlled release fertilizers can be incorporated uniformly throughout the soil before planting or applied to the soil surface in established plantings. Soluble fertilizers are useful for fast nutrient release to plants. Some communities have restrictions on the use of fertilizers during the rainy season usually defined as June through September. Deadheading (removal of fading or dead flowers) on some plants will keep them attractive and encourage more blooms. The faded blooms of most plants can be removed with finger and thumb. Others will require a clipper. Not all plants require deadheading. S*A plant that has already been grown to blooming or near-blooming size before being planted out in a usually formal area for seasonal display of colorful flowers or foliage.

Keep us in mind if you would like to change your winter plantings to summer! I hope you all have a good week, check us out next Monday for a new blog! Have a happy and blessed Easter weekend!
