Zone 9 Rose care: a guide for growing roses in Zone 9 Gardening Gardeners in Zone 9 find it easy enough in most countries to flower roses in a given season only during two to three winters. But in Zone 9 flowers can flower all year round, and in winter they are spectacular. Choose a variety of rose bush for Zone 9 When you are planning a rose garden, the answer is pretty much yes, but you need to take into account your soil type, the moistness and if salt spray from the sea is available in coastal areas. Old garden roses, being the easiest to grow, bloom only once a year and are susceptible to fungi like black spot, Cercospora leaf spot and powdery mildew, so they need to be treated with fungicides.
Hybrid and other formal roses will need more maintenance. Rose Cultivation, with the exception of the cultivars Mrs B.R. Cant and Louis Phillippe, are perfect low maintenance roses for zone 9 winters. Knock-off Rose is another very reliable solution, bearing the weight of zone 9 summer weather. In dry parts of Zone 9 with strong summer temperatures, many formal roses, of the Margaret Merril-Rose variety, grow in warm, humid conditions and flower throughout the year.
There are many other options, so if you have more ideas, please contact your local garden centre or nurseries. Care for roses In zone 9, proper location and maintenance are necessary to sustain the roses. The roses need to receive six hours of sunshine each day and good soil with significant quantities of organic matter. To keep formal roses healthy, water them every week, cut off deadhead in order to lift the level of organic matter and spray with the fungicide recommended for the species.
This is especially important if the soil is sandy or if you live in a drought. Formal roses in zone 9 should be fertilised once a month in the early spring until the end of the autumn and pruned in spring. Many of the rose varieties will grow bigger in zone 9 than in colder zones and should be tended to a higher frequency if you wish to keep them smaller. In coastal Zone 9 regions such as Florida, make sure your water supply is suitable for growing roses: these cannot tolerate water with more than 1800 ppm salts.
Alternatively, consider salt spray: beach roses (Rosa rugosa) and flower and seedling roses are the best candidates for the showers. Most other roses must be planted in protected places to reduce exposure to the spray.
