Updated: September 25, 2022

If you’re looking for a colorful and eye-catching addition to your garden, the firecracker plant may be just what you need. This plant, also known as the coral fountain plant, is a member of the Bignoniaceae family and is native to Brazil. Its bright red-orange flowers and delicate foliage make it a popular choice for gardeners looking to add a pop of color to their outdoor spaces.

But caring for a firecracker plant can be tricky if you’re not familiar with its needs. In this article, we’ll go over the basics of firecracker plant care to help you keep your plants healthy and vibrant.

Planting and Soil Requirements

Firecracker plants prefer well-draining soil that’s slightly acidic (around 6.0-6.5 pH). If your soil is too alkaline, you can add some sulfur or aluminum sulfate to lower the pH. These plants also need plenty of sunlight and warmth, so choose a spot in your garden that gets at least six hours of direct sunlight each day.

When planting your firecracker plant, make sure to give it enough space to grow. These plants can get quite large (up to six feet tall and wide), so don’t overcrowd them with other plants.

Watering Needs

Firecracker plants need regular watering, especially during hot weather. However, they don’t like soggy soil, so make sure not to overwater them. A good rule of thumb is to water deeply once or twice a week, depending on how dry your soil is.

During the winter months, you can cut back on watering since the plant will be dormant.


To keep your firecracker plant healthy and blooming, you’ll need to fertilize it regularly. Use a balanced fertilizer (10-10-10) once a month during the growing season (spring and summer). You can also use a slow-release fertilizer if you prefer.


Firecracker plants don’t need much pruning, but you can trim them back in the fall or winter to keep them from getting too large. Cut back any dead or damaged branches, and shape the plant as needed.

Pests and Diseases

Firecracker plants are relatively pest-free, but they can be susceptible to spider mites and whiteflies. If you notice these pests on your plant, try using insecticidal soap or neem oil to get rid of them.

As for diseases, firecracker plants can be prone to root rot if they’re overwatered. Make sure to let the soil dry out between waterings to prevent this problem.


Can I grow firecracker plants in containers?

Yes, firecracker plants can be grown in containers as long as the container is large enough to accommodate their size. Make sure the container has drainage holes and use a well-draining potting mix.

How often should I fertilize my firecracker plant?

Fertilize your firecracker plant once a month during the growing season (spring and summer) with a balanced fertilizer (10-10-10).

Do firecracker plants attract hummingbirds?

Yes, firecracker plants are known for attracting hummingbirds with their bright red-orange flowers.

Can firecracker plants survive cold winters?

Firecracker plants are not cold-hardy and won’t survive freezing temperatures. If you live in a colder climate, you’ll need to bring your plant indoors or treat it as an annual.

In conclusion, caring for a firecracker plant isn’t too difficult as long as you give it the right amount of sunlight, water, and fertilizer. With a little bit of attention, you can enjoy the vibrant colors of this beautiful plant in your garden for years to come.
