Growing Firecracker Flowers

The best part about growing and caring for Firecracker shrubs is that they do not require much effort on your part to thrive. Firecracker flowers have no high demands from their owners, and they are more than pleased as long as they are provided with proper light conditions, temperatures, and lots of love.

Firecracker flowers are not picky when it comes to how much sunlight they can tolerate. However, these shrubs grow at their best when they receive plenty of bright and indirect light all-year-round with partial sunlight during the hot summer months. Make sure you protect your plants from any direct sunlight exposure because it may scorch their leaves and burn the blooms.

In terms of temperatures, Firecracker flowers are frost tender and prefer mid-cool to slightly warm environments. If you live in a region with harsh winters, you should grow your shrubs in a greenhouse or conservatory. You can also bring potted plants inside when temperatures start to drop below 50 °F (10 °C). When they are exposed to lower temperatures for long periods, these plants will grow slower and produce fewer flowers than usual.

As with most shrubs, Firecracker flowers can be occasionally bothered by whiteflies and red spider mites. To prevent any kind of infestation, you can place yellow sticky cards near your plants or add a reflective mulch under them. If your shrubs have already been infested, treat the unhealthy parts with suitable insecticides and pesticides.

Planting Firecracker Flowers

When it comes to the planting substrate, Firecracker flowers can withstand a wide range of soil types from acidic to alkaline. However, no matter what kind of soil you choose to plant your shrubs in, it must have excellent drainage. In general, they thrive in soils like sand, loam, chalk, and clay.

In the first two years after planting, young Firecracker flowers will need extra phosphorus to ensure healthy root development. After they are settled in their new environment, your Firecracker plants will benefit from regular fertilizing during their active growing season. Feed your shrubs with an all-purpose fertilizer or one that is specifically designed for flowering plants once every year.

You can prune your shrubs to rejuvenate them and encourage new growth, flower production, and increase airflow to prevent any possible disease. Firecracker flowers are best pruned each year after their blooming period has ended in late winter or spring. However, it is worth mentioning that these shrubs usually require little to no pruning, but you can do it regularly if you want to maintain a certain size and shape.

Watering Firecracker Flowers

This process can be pretty fun because Firecracker flowers can be tolerant of drought for short periods if they are grown in proper soil. Yes, these plants require well-draining soils, but they also love some moisture to keep their feet wet. Be careful though, as over-watering is one of the most common problems met while caring for these shrubs. You can avoid waterlogging or soggy conditions by allowing the excess water to drain away.

In general, you can make your Firecracker flowers happy by watering them only once every week. Depending on the environmental conditions, the frequency of watering may vary from one plant to another. In hot and dry summer months, these shrubs will probably need watering more often than they usually do. Moreover, you can water your plants only once a month if you live in a region with lots of humidity like abundant rainfalls.

During their blooming period, from fall to spring, Firecracker flowers will need regular watering to keep their blooms in shape. Make sure you always check the soil in-between waterings and provide with water only when the top inch (2.5 cm) of soil feels dry to the touch.

Propagating Firecracker Flowers

Firecracker flowers are too gorgeous to be missed and no one can ignore their hypnotic presence. Used very often in landscape decoration, they can also be a nice dash of color in any home or garden, whether it is yours or a loved one’s. Luckily, these shrubs can be propagated through softwood cuttings without difficulties along the way.

If you want to propagate your Firecracker flowers using softwood cuttings, you must do it in the spring after their blooming period has ended. The cuttings taken from the mother plant should have at least three pairs of leaves on the top half and none on the bottom half. Once you have as many cuttings as you want, you can plant them in individual pots filled with suitable and well-draining soil.

For optimal results, you can cover the softwood cuttings with glass or place them in a warm and shaded location to protect them from any direct sunlight exposure. If you water the cuttings once every day for a few weeks, they should develop a healthy root system very fast. When the Firecracker flowers babies can stand on their own, provide them with the same fertilizer used for their parent to encourage better growth and blooming.

In Conclusion

As a plant-lover, you know that there is always room for one more ornamental houseplant. Now that you already know the basics of growing and caring for these eye-catching babies, you have no reason not to give them a chance. As long as you pay attention to your Firecracker flowers’ needs, you will have a flowering shrubby friend around for decades!
