Common Name

Rose

Soil

Roses prefer acidic soil of pH 6.5 (sand) but will tolerate alkaline soils up to pH 7.5 (chalk). Mix 25 litres farmyard manure, or pulverized tree bark with bone meal, in soil before planting. Broadcast rose fertilizer in early Spring.

Sun Aspect

Full Sun - continuous, direct exposure to 6 hours or more of sunlight per day.

Soil Moisture

Moist - Soil is moist without being soggy because the texture of the soil allows excess moisture to drain away. Most plants like about 1 inch of water per week. Amending your soil with compost will help improve texture and water holding or draining capacity. A 3 inch layer of mulch will help to maintain soil moisture and studies have shown that mulched plants grow faster than non-mulched plants.

Modern Roses: 19a English Roses

David C.H. Austin OBE (born 1926) is a rose breeder and writer who lives in Shropshire, England. His emphasis is on breeding roses with the character and fragrance of Old Garden Roses (Gallicas, Damasks, Alba roses, etc.) but with the repeat-flowering ability and wide colour range of modern roses such as Hybrid Teas and Floribundas. Though Austin's roses are not officially recognised as a separate class of roses by, for instance, the Royal National Rose Society or the American Rose Society, they are nonetheless commonly referred to by rosarians, at nurseries, and in horticultural literature as 'English Roses' (the term he uses) or 'Austin Roses'.

Modern Roses: 19b Patio Roses

"An excellent new group, somewhere between a miniature and a floribunda in character. They are larger and more robust than miniatures, frequently having charming rosette flowers and neat, bushy growth. They are hardy and repeat well." from David Austin Roses.

Modern Roses: 19c Miniature Roses

"Miniatures grow to a height of between 12 and 18 inches, sometimes more according to growing conditions. They have been greatly improved in recent years and the newer varieties include some excellent bushy plants with prettily-formed flowers. They are useful for window boxes and tubs as well as very small gardens." from David Austin Roses.

Modern Roses: 19d Dwarf Polyantha Roses

"These have small rambler-like flowers produced in large, closely-packed bunches. Polyanthas are extremely tough and flower continuously. They form short, compact bushes ideal for the front of borders. These pretty little roses have recently enjoyed a return to popularity." from David Austin Roses.
