scarlet firethorn

Scarlet firethorn plants prefer to have moist but not soggy soil. To achieve the best balance of water for your shrub, water it thoroughly once a week, allowing the water to penetrate the roots. If the weather is particularly hot or dry (such as in periods of drought) an additional soaking may be necessary. Be sure to water near the base and not overhead as wetting the foliage can lead to fungus. Avoid frequent light waterings as this can lead to over-watering and root rot.

Scarlet firethorn plants prefer full sun or partial shade. However, in areas with intense summer heat, some afternoon shade can be beneficial. In colder climates, it can tolerate full sun in the winter months. The plant does not require any special attention in terms of sunlight; however, it does best when it receives at least 6 hours of direct sunlight per day. As with all plants, too little light will result in sparse flowering.

Scarlet Firethorn should be pruned in late winter or early spring. For light pruning, this shrub can be managed on a yearly basis, while heavier pruning is best every alternate year. Before pruning, inspect the plant for dead, diseased or damaged branches and remove them immediately. For a more formal look, remove 4-5 oldest or excess branches from the center of the plant and thin out the foliage to open up the shrub and study the architecture. Alternatively, you may also shape the plant like a pyramid, by pruning top shoots to a shorter length which will encourage more even flow of growth around the top. You can further selectively prune to shape the plant and promote flowering. To ensure abundant blooms, remove any dead, weak or spindly growth or any branches that are not bearing flowers. As with all pruning, remember to remove no more than a third of the bush in 1 season.
