Watering a Firecracker plant is important, but do not overwater it. Water your Firecracker plant frequently but make sure that the top layer of soil dries out between applications. A week’s worth of watering is sufficient for most plants. In warmer climates or in containers, a weekly watering may be necessary.

To help ensure good growth, mulch the soil around the plant to conserve moisture and prevent weeds. Honeysuckle will flower on either old or new growth, so it is essential to water it regularly.

To propagate honeysuckle, take a cutting from a young plant. Plant the cuttings outdoors once the danger of frost has passed and the soil has warmed. The cuttings should have several sets of leaves with one or two leaf nodes left bare. The cuttings should be placed on a soil-rich, slightly moist surface to stimulate growth.

Honeysuckle is a heat-tolerant climber with white or dark pink flowers. These flowers are filled with sweet nectar and have been known to attract bees. Other species are pollinated by moths, but the strongest fragrance is found in the evening. Some species attract hummingbirds and other critters. Honeysuckle blooms from May through October.

For the best results, prune the honeysuckle plant in winter to encourage flowering. Honeysuckle requires minimal pruning, but the plant does require some attention. You can remove up to a third of the stems each year after flowering. Pruning early may stunt growth or cause the plant to die.
