Rubus, derived from ruber, a latin word for red, is the genus of plants generally called brambles. The epithet spectabilis means spectacular due to Salmonberry’s showy flowers and fruits. The common name Salmonberry is thought to have come from the natives’ fondness for eating the berries with salmon roe, but it could also be due to the orangy-pink color of the berries.
Bushes planted in boglike areas are unlikely to need moisture level monitoring. Otherwise, in times of drought give the area a thorough soaking at least once a week.
Work compost or 10-10-10 fertilizer into the soil in early spring before the bushes flower. Either lay a narrow band 1-inch thick about 6 inches in front salmonberry patches or encircle individual bushes. Lightly work the fertilizer into the top several inches of the soil with a garden fork or spade.
Conduct a soil test to determine the pH level of the soil. almonberries are unfussy about pH levels, but, in general, shrubs in the Rubus genus prefer neutral to slightly acidic soils -- about 6.0 to 7.0.
Prune as needed to keep aggressive growth under control. After the berry season passes in late summer, cut back old stems at the base of the plant, leaving new ones to flourish. Old stems are orange and smooth, while new, green stems still bear thorns.
