Firebush: Grow & Care for Hamelia Patens
Firebush, also known as Hamelia Patens, is a large woody shrub native to the southern United States. Firebush (Hamelia Patens) can grow up to 15 feet (4.5 meters) tall, but it can also remain smaller. It grows quickly, growing a few feet in its first growing season. Firebush (Hamelia Patens) is a favorite plant in many southern states, such as Florida, because it is native and easy to grow, especially because it produces gorgeous flowers from spring through fall.

How to Choose and Prepare a Planting Site

You can plant a Firebush plant preferably outdoors, in pot or in ground at a spot receiving below growing conditions for the plant 
  • Direct bright sunlight for more than 6 hours a day.
  • Soil should be nutrient rich and well drained.
  • Apply Water when soil (1-2 inch) feels dry to touch. 

When to Grow Firebush (Hamelia Patens)

Although firebush thrives in all areas of Florida, where you live decides when the best time to plant the shrub into the landscape is. Those living in South Florida where temperatures are warm year-round can plant firebush into the landscape nearly all year.
  • Area Planting Dates
  • North Florida Apr – Sep
  • Central Florida Apr – Sep
  • South Florida Feb – Dec
However, those living in colder areas of Central and North Florida where frosts and freezes are common shouldn’t put firebush into the landscape until temperatures warm in spring. To give the root system time to establish itself before the cold winds of winter come calling, plant the firebush spring through late summer.
If you're desiring to grow firebush in a container, you can plant year-round. However, those living in colder locations in the state should bring the container into a warm and protected location during winter if you don’t want the plant to die to the ground once winter's cold temperatures strike.

How to Grow Firebush (Hamelia Patens)

Firebush (Hamelia Patens) plant may be propagated with seeds and cuttings.

Firebush (Hamelia Patens) Propagation with Seeds

  • Collect pods and remove the seeds once they are dry.
  • Moisten the peat in seedling trays and sow them.
  • Place the tray indoors, in an area getting full sunlight.
  • Germination being 3 weeks later.
  • Once the seedlings are big enough to handle, move them to tier permanent location and with good growing conditions, you will notice plenty of orange-red flowers soon enough.

Firebush (Hamelia Patens) Propagation with Stem Cuttings

  • Obtain cuttings about 6 inches long with three to four leaves.
  • Treat with indolbuteric acid if the cutting is not from a commercial nursery by dipping the cutting for two to three seconds in a 1-to-20 strength treatment. Cuttings from commercial nurseries are generally pre-treated.
  • Place the cutting into perlite or sand by digging a shallow hole with a trowel.
  • Place the cutting in full sun in a warm environment. If the temperature dips below 85 degrees Fahrenheit, place the cuttings on a plant warming pad to maintain the bottom temperature of the cuttings for best results. While varying temperatures won't prevent the cutting from rooting, Dr. Jerry Parsons, a horticulturist in Texas, found that temperatures between 85 and 101 degrees Fahrenheit ensured healthier and stronger growth in the root system.
  • Water daily to keep the soil well-hydrated.
  • Transition the cuttings to the outdoors over a one-week period when the risk of frost has passed Each day, take the cuttings out, first to a shaded area and then to an increasingly sunny area. Each night, bring them back indoors.
  • Plant outdoors in a location well-suited to growing a tall hedge. While firebush can grow in shade, it grows and flowers in full sun, providing a full season of orange-red flowers and fruit and growing quickly.

How to Care for Firebush (Hamelia Patens)

Firebush Light Care

Though firebush (Hamelia Patens)  can tolerate partial shade, it prefers the warmth of full sunlight, at least six or eight hours a day. It's believed that the more sunlight the plant gets, the more plentiful its blooms will be.

Firebush Soil Care

Firebush has the benefit of growing easily in a variety of different soil conditions. That being said, it prefers a mixture that's on the drier side, and whatever type of soil you plant it in should be especially well-draining, as the plant can be prone to root rot. Additionally, soil pH isn't of much importance to firebush—it can thrive in a blend that ranges from neutral to acidic.

Firebush Water Care

In general, Firebush (Hamelia Patens) won't require a lot of watering. Once it establishes, it becomes almost self-sufficient as its roots seek water in the deep soil. That doesn't mean you should forget about irrigation altogether. You should always strive to keep the well-drained soil moist especially in the dog days of summer. Don't overwater it, however. This is a hardy bush that can handle drought but not soaked soil. You can use a well-balanced fertilizer in the early spring to encourage flowering.

Firebush Temperature & Humidity Care

Firebush (Hamelia Patens)  prefers an ideal temperature 15 degrees Fahrenheit. It can withstand very cold temperature up to -1 degree Celsius.

Firebush Fertilizer Care

Established trees should be fertilized every 2-3 years. Feed in early spring when plants start growing. Fertilizers are available in many forms: granulated, slow-release, liquid feeds, organic or synthetic. Determine which application method is best for the situation and select a product designed for trees and shrubs, or go with a nutritionally balanced, general-purpose formula such as 10-10-10. Always follow the fertilizer package directions for application rates and scheduling. Over-fertilizing plants or applying at the wrong time during the growing season can result in plant injury.

Firebush Pruning Care

Pruning may be needed to remove dead branches, encourage bushier growth, promote more flowers, or maintain a specific size or shape. Dead branches should be removed close to the trunk, flush with the bark. When pruning to control a plant's size or shape, cuts should be made just above a leaf bud and at a slight angle. This bud will be where the new growth sprouts. Many shrubs can be regularly sheared to keep them shaped as a hedge, edging or formal foundation planting.
Always use sharp, clean tools when pruning. There are many tools available depending on the job. Hand shears, pruners, and loppers are ideal for most shrubs. Pole pruners and tree saws are better for large, mature shrubs or trees. If a tree is so large that it can't be safely pruned with a pole pruner, it is best to call in a professional tree service.

Firebush Pests & Diseases Care

Like most other plants that grow in the tropics, firebushes (Hamelia Patens) are known to attract unwelcome guests. These often include common garden species aphids, thrips, starscream, plant scales, mealworms and mealybugs. Each one is enough to do a lot of damage to your beautiful firebush. You can remove them by using insecticides or organic neem oil.
As for diseases, in the middle of summer, the bush is infected with three kinds of diseases. These are:
Gray mold: disease caused by a fungal infection that leaves a powdery residue on leaves. Sometimes you see it on the stem as well. It is best to remove symptomatic leaves or branches.
Root rot: The cause of this problem is usually man-made. If plants are overwatered or without well-drained soil, the accumulation of water can cause root rot. Symptoms include leaves with brown tips and wobbly stems. Stop watering the soil until the top 2 inches are dry.
Powdery mildew: Another fungal infection that leaves spots on leaves in the form of powder. You can treat it with neem oil or remove all infected leaves. If the infection is spreading, a microbicide may be a good solution.
