Tips for Keeping Your Plants Healthy:

If you’re looking to keep your firespike plants healthy, there are a few things to keep in mind. First, make sure they’re getting enough sun.

They need at least six hours of sunlight each day to stay healthy and produce those beautiful blooms. Secondly, water them regularly.

The soil should be moist but not soggy – about an inch of water per week is ideal. Lastly, fertilize your plants every month or so to give them the nutrients they need to thrive.

Lighting and Temperature

Firespikes are tropical plants, so they need full sun to partial shade and warm temperatures to thrive.

If you live in an area with cooler summers, you can grow firespikes in containers and move them indoors when the temperature starts to drop.


Soil and water are two of the most important things to consider when planting firespikes. The soil should be well-drained and rich in organic matter.

It’s also important to keep the roots of the plant moist, so make sure to water it regularly.


While the firespike is a tough plant that doesn’t require a lot of attention, it will benefit from being fertilized once a year.

The best time to do this is in the spring, before new growth begins. A complete fertilizer with a ratio of 12-12-12 or 16-16-16 will work well.


Pruning is important to keep the plant from getting too leggy, and it also encourages new growth. You can prune it back by about a third in late winter or early spring.

The firespike is an easy plant to grow and is tolerant of most soils as long as it has good drainage.


Firespikes are drought tolerant but will do best if given a good soaking once a week during the hot summer months.

If you live in an area with high humidity, be sure to plant them in well-drained soil to avoid root rot.


The average size of a firespike is six to eight feet tall and four to six feet wide, making it a large shrub.

Color: The leaves are dark green and the stems are purple with red flowers.


Flowering plants are always a welcome addition to any garden. They add color, attract wildlife, and provide visual interest.

If you’re looking for a large, eye-catching plant that will do all of those things, the firespike might be the perfect choice for you.

Propagating Firespike

Firespike is a popular plant because it is so easy to grow. You can grow it from cuttings, which only takes a few minutes. Here’s how it’s done:

Cut a piece of your firespike, preferably on a softwood tree branch. Remove the leaves from the cutting’s base.

Dip the cut-off end of the plant in the rooting hormone. Plant the plant with the cut side facing the direction you want the new plant to grow.

That’s all. They root quickly, and you’ll have another plant in a matter of minutes.

Firespike is a popular plant because it is so easy to grow and only takes a few minutes to produce a new plant from a cutting. Try it yourself and see how easy it is!
