scarlet firethorn

Scarlet firethorn plants should be watered well when first planted. Water deeply and slowly after planting to help the soil settle and encourage root growth. Once established, water the plant deeply every week to 10 days during the growing season. Reduce the frequency of watering during the winter if the plant is established, as the plant will become dormant. In hot summer weather, the plant may require more frequent watering. Watch for signs of wilting--the plant may need more frequent watering when temperatures are high and rainfall is low.

Scarlet Firethorn (Pyracantha coccinea 'Lowboy') is an evergreen shrub that tends to thrive in areas exposed to sun. It should be planted in an area that receives full sun for at least 6 hours a day. This will allow it to take in sufficient amounts of sunlight needed for optimal growth. It is best to place the plant in the morning sun as the afternoon sun can be too intense during the hot summer days.

Scarlet firethorn (Pyracantha coccinea 'Lowboy') benefits from pruning to maintain a balanced shape and to remove dead and diseased stems. The best time to prune is from late winter to early spring before it puts on new growth. When pruning, remove no more than 1 third of the stems at a time. Thin the bush to open up the inner stems to improve air circulation. Remove cross branches or branches growing in the wrong direction, or leggy, congested stems. Make your cuts just above an outward facing side shoot or bud as close to the node as possible. Wearing gloves is wise, as the thorns are incredibly sharp.
