One of the most common firecracker plant problems is their wild growth habit, which can only be controlled with aggressive pruning.
Sometimes called firecracker fern, the firecracker plant (Russelia equisetiformis) is not a true fern but a perennial plant grown for its tubular red flowers and cascading, rush-like foliage, according to Monrovia.
Pruning is a key aspect of firecracker plant care, although it is otherwise a low maintenance and undemanding plant species.
Pruning Firecracker Plant A mature firecracker plant size tops out at 3 to 5 feet in height with sprawling, 3- to 5-foot-wide branches that can easily overwhelm nearby plant
It is best to prune in late winter or early spring, according to Monrovia, because this species blooms on new growth. During the growing season, continue to prune it to control its size, if necessary.
Firecracker plant can be pruned back to just a few inches in height without suffering any damage, according to the University of Arkansas Cooperative Extension.
Simply cut back the entire plant to between 4 to 6 inches in height using sturdy, sharp pruning shears before new growth emerges in early spring.
