General Culture:
Best grown in medium moisture, slightly acidic, well-drained garden loams in full sun to part shade. Best flowering and disease resistance generally occur in full sun, however. Water 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 moisture, 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.
Noteworthy Characteristics:
FOURTH OF JULY' is a large-flowered climbing rose which typically grows 10-14' tall and features profuse clusters of sweetly scented, semi-double blooms (to 4.5" diameter) which are red and white striped. Repeat bloomer. Deep green foliage. Parentage: R. 'Roller Coaster' x R. 'Altissimo'. 1999 All-America Rose Selection winner.
Problems:
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.
Uses:
This climbing rose may be grown on walls, arbors, trellises, along fences or around pillars.
