FAQs (Frequently Asked Questions)
Q. What are English or David Austin roses, and how do they perform in Metro Vancouver?
A. English roses, bred by David Austin, combine the flower form and fragrance of old roses with the repeat-blooming habit of modern shrubs. In Metro Vancouver and the Pacific Northwest (zones 7 to 8), they are reliably hardy and flower in flushes from late spring through fall. Our cool, wet springs mean excellent color and fragrance, but also a need for good air circulation to limit leaf diseases. With proper siting and care, they perform very well here.
Q. How much sun do English roses need in the Pacific Northwest?
A. Aim for at least 6 hours of direct sun daily, with morning sun being especially helpful to dry leaves after dew or rain. In our mild summers, 8 hours of sun will improve bloom quantity and repeat. Light afternoon shade is fine, but too much shade leads to fewer flowers and more disease. Avoid dense shade or spots that stay damp and still.
Q. How big do English roses get here, and how far apart should I space them?
A. Most English shrub roses grow about 3 to 5 feet tall and 3 to 4 feet wide in our climate (roughly 0.9 to 1.5 m tall, 0.9 to 1.2 m wide). Many listed sizes are conservative here because our growing season is long but not overly hot. Space shrubs 3 to 4 feet apart for good air flow; larger varieties may need 4 to 5 feet. English climbers often reach 8 to 12 feet (2.4 to 3.6 m) and should be spaced 6 to 8 feet apart.
Q. When and how should I plant English roses in Metro Vancouver?
A. Plant container roses from spring through early fall, avoiding heat waves and waterlogged conditions. Plant bare-root roses late winter to early spring when the soil is workable. In our wet winters, set the bud union of grafted plants at or just above soil level to reduce rot, then mulch over the root zone; own-root plants can be set at the same depth they grew in the pot. Water in well and keep evenly moist until established.
Q. What soil and pH do they prefer?
A. English roses thrive in rich, well-drained loam with plenty of organic matter. A slightly acidic pH of about 6.0 to 6.5 is ideal, though 5.5 to 7.0 is acceptable. If you have heavy clay, amend generously with compost and consider a raised bed to improve drainage. Avoid planting in low spots where water sits in winter.
Q. How should I water English roses in our climate?
A. Water deeply and infrequently, soaking the root zone to a depth of 8 to 12 inches. In summer, most established shrubs need about 1 to 1.5 inches of water per week total, including any rainfall. Use drip irrigation or a soaker hose in the morning to keep foliage dry and reduce disease. In spring and fall, adjust for rainfall and check soil before watering to avoid saturation.
Q. What is a good fertilizing schedule for English roses?
A. Feed in early spring when new growth begins, using a balanced rose fertilizer or a slow-release organic blend. A second light feeding after the first big bloom flush (late June to early July) supports repeat flowering. Stop fertilizing by mid August so plants can harden off for winter. Always water before and after feeding to protect roots.
Q. How and when should I prune English shrub roses and climbers?
A. Prune in late winter to early spring when buds begin to swell, typically February to March. For shrub types, remove dead, damaged and crossing canes, then reduce the plant by about one-third to shape and open the center for airflow. For repeat-blooming climbers, tie long canes horizontally or at a low angle, then shorten lateral shoots to 3 to 5 buds; do major thinning in late winter. Once-blooming climbers should be pruned right after flowering.
Q. Are English roses disease resistant here, and how can I reduce black spot or mildew?
A. Many modern English roses have good disease tolerance, but our rainy springs favor black spot and mildew. Choose resistant varieties, provide 3 to 4 feet of spacing, water at the base, and mulch 2 to 3 inches to limit soil splash. Remove fallen leaves and avoid evening overhead watering. Proven performers for disease resistance here include ‘Olivia Rose Austin’, ‘The Poet’s Wife’, ‘Lady of Shalott’, ‘Boscobel’ and ‘Princess Alexandra of Kent’.
Q. What pests should I watch for, and how do I manage them?
A. Common pests include aphids and rose slug sawflies, and occasionally spider mites during hot, dry spells. Knock aphids off with a firm water spray or use insecticidal soap as needed. Rose slug sawflies skeletonize leaves; handpick small numbers, or use spinosad on active larvae (note that Bacillus thuringiensis does not work on sawflies). Encourage beneficial insects and keep plants healthy to reduce outbreaks.
Q. Can I grow David Austin roses in containers?
A. Yes, many varieties do well in large containers. Choose a pot at least 18 to 24 inches wide with drainage holes, use a high-quality potting mix, and elevate the pot on feet to improve winter drainage. Water more frequently than in-ground plantings and fertilize lightly through the growing season. In winter, protect pots from sitting in saucers and from excessive saturation.
Q. Do English roses need winter protection in Metro Vancouver?
A. In zones 7 to 8, most English roses overwinter well with minimal protection. Stop fertilizing by mid August, avoid heavy pruning in fall, and apply a 2 to 3 inch mulch after the first light frost to buffer soil temperatures. During rare cold snaps, you can mound mulch or leaves 4 inches around the crown for extra insurance. Ensure containers drain freely so roots are not waterlogged in winter.
Q. Are English roses deer or rabbit resistant?
A. Roses are not reliably deer resistant; hungry deer will browse new growth and flowers even with thorns. Rabbits may chew young canes at the base. Use fencing, netting or repellents where browsing is common, especially during establishment. Placing roses closer to the house and using companion plants with strong scent can also help, but protection is the most reliable approach.
Q. How do I deadhead English roses to encourage repeat bloom?
A. After a flush, snip spent blooms just above a strong, outward-facing 5-leaflet leaf to shape the plant and stimulate new shoots. Keep up with deadheading through summer for the best repeat. In early fall, you can reduce or stop deadheading if you want hips to form and to help the plant slow down for winter. Always clean your pruners and avoid cutting in wet conditions to limit disease spread.
Q. Are your English roses own-root or grafted, and what does that mean for care?
A. English roses are sold both own-root and grafted, and both perform well in our area. Own-root plants grow on their own wood and tend to recover better from winter or damage, while grafted plants may establish faster and flower sooner. If your plant is grafted, remove any suckers that arise from below the bud union by pulling them off at the source. Plant grafted roses with the bud union at or just above soil level here to reduce rot in wet winters.
Q. Which David Austin varieties are top choices for the Pacific Northwest?
A. Good, dependable options include ‘Olivia Rose Austin’, ‘Lady of Shalott’, ‘The Poet’s Wife’, ‘Boscobel’, ‘Princess Alexandra of Kent’ and ‘Queen of Sweden’. These are known for reliable repeat bloom and better-than-average disease tolerance in our climate. For climbers, consider ‘The Generous Gardener’ or ‘Tess of the d’Urbervilles’ trained with good airflow. Always check mature size and choose a spot with morning sun and space to breathe.
Q. What are good companion plants for English roses in our region?
A. Choose companions that like similar sun and soil and will not crowd the rose. Great choices include catmint (Nepeta), salvias, hardy geraniums, alliums, lavender and low ornamental grasses. These help with color continuity, pollinators and airflow, and they dry quickly after rain. Avoid tall, dense shrubs right next to roses, which can trap moisture and shade them.
Q. Any tips to reduce disease pressure without routine spraying?
A. Start with resistant cultivars and a sunny, breezy site. Water at the base in the morning, keep 3 to 4 feet of spacing, and mulch to limit soil splash. Prune to open the center, promptly remove infected leaves and clean up leaf litter in fall. If needed, targeted fungicides can be used preventively in spring, but many gardeners succeed here with good cultural practices alone.
