How to Grow Firespike Plants
Firespike plants are a breeze to care if you can offer the right conditions. Naturally found in tropical climates, these plants love hot weather and plenty of water.
Firespikes can grow in partial shade as well as full sun. They like rich soil, but can also grow in a sandy medium. And, if you forget to irrigate them and find your firespike looking a little droopy, a good watering will bring them back to life. On top of this, there are not any common pests or diseases that cause much trouble for this plant.
These shrubs can grow anywhere from four feet to eight feet and beyond. They make a wonderful addition to cutting and butterfly gardens. Because of their size, they also make great backdrops to smaller plants.
Firespikes love sunshine. Naturally found in tropical environments, these plants thrive in bright light.
Unlike most plants, firespikes will still bloom in the shade. For more blooms and a healthier plant, however, more sunshine is best.
This plant isn't fussy when it comes to soil pH levels. For optimum growth, however, firespikes like rich, well-draining soils. Sandy soils will also be tolerated. Compost-based soil is a great option for extra nutrients that will keep your firespike healthy and blooming.
Keeping your firespike well-watered is important because these plants depend on plenty of moisture. Keep it consistent and, if you live in a dry area, water daily. If you forgot for a day or so and see the plant wilting, don’t panic. Firespikes are hardy, and will most likely be just fine after a good drink.
Keeping a layer of mulch on the soil around your plant will help retain moisture and keep the soil from drying out too quickly.
Temperature and Humidity
Native to Mexico and Central America, these plants love hot weather and moderate to high humidity. Firespikes are very hardy when it comes to hot temperatures, but not so much with cold temperatures.
It can survive in areas with light frost, but heavy frost will kill it. In areas with light frost, you will see blooms in late summer until the frost comes. For areas without frost, your firespike could bloom all year long.
This plant is easy-going and doesn’t need any specific fertilizers. A general, well-balanced, slow-release fertilizer is ideal. Fertilizing in the spring to encourage fresh, healthy growth and blooms should be enough, but you can fertilize up to three times in a year.
Going along with its overall easy-going personality, the firespike is very simple to propagate from cuttings. Here’s how:
- Trim a clipping off of your firespike, preferably on a softwood branch.
- Trim leaves off of the bottom half of the cutting.
- Dip the cut end into rooting hormone.
- Plant with the cut side down where you would like your new plant to grow.
That’s it. These plants root extremely easily, so you’ll have another plant in no time.
Again, firespike makes for a low-maintenance addition in your garden and you won't need to invest a lot of time in regular pruning or maintenance. Occasional pruning is all that is needed since some branches can get long, unruly, or gangly looking. Give them a snip whenever you feel like your plant needs a little haircut.
If you live in an area with light frost, prune your firespike to the ground in the spring once the danger of frost is gone. This will encourage fresh, healthy growth from the plant’s base. For areas without frost, simply cut the flowering stems to the ground when they are done blooming.
