Abstract-
Grow in moderate wet, slightly acidic, well-drained garden loams in full sun. Tolerates some light shade, but best flowering and disease resistance generally occur in full sun. Moisture deeply and regularly (mornings are best). Avoid overhead watering. Good air circulation promotes vigorous and healthy growth and helps control foliar diseases. Summer mulch helps retain dampure, keeps roots cool and discourages weeds. Remove spent flowers to encourage rebloom. Crowns need winter protection in cold winter areas such as St. Louis. Remove and destroy diseased leaves from plants, as practicable, and clean up and destroy dead leaves from the ground around the plants both during the growing season and as part of a thorough cleanup during winter (dormant season). Prune as needed in late winter to early spring.
Attributes-
THE HERBALIST is a compact David Austin English shrub rose which typically grows to 4” tall and 3” wide. Shrub size in large part depends upon the climate and environment (e.g., shrubs grow smaller in cool summer climates and larger in hot summer climates). Features semi-double, red roses (to 3’ diameter) with a center clump of golden stamens. Blooms from May to frost. Blooms resemble old Gallica roses. Light fragrance. Dark green foliage with red prickles on the canes. “AUSsemi” is the original cultivar designation for this rose.
Issues-
Roses are susceptible to a large number of diseases, the most common of which are black spot, powdery mildew, rust and rose rosette. Although good cultural practices are the first line of defense in disease control, regular preventative fungicide applications throughout the growing season are usually required, particularly in humid climates with regular rainfall such as the St. Louis area. Potential insect problems include aphids, beetles, borers, scale, thrips, rose midges, leafhoppers and spider mites. Local rose associations and extension services are usually able to offer specific recommendations and advice for selecting and growing roses.
Common Applications-
This rose grows well as a specimen or in small groups in borders, cottage gardens, foundations or rose gardens. Also effective as a low hedge. Red roses contrast well with a white picket fence.
