AUTUMN IS probably the worst season for rose lovers. The excitement of the first flush of blooms is a distant memory yet it is still too early to think about winter pruning. A combination of neglect over the holiday season and the weather takes its toll, and often roses are looking worse for wear as we enter autumn. Certainly this season has been challenging for rose growers around the country with lots of wind and rain and cooler temperatures than normal pretty much summing up the season. There are a few things you can do in autumn to get the best out of your roses and also prepare for winter time. DEADHEADING Continue to deadhead spent blooms until the end of March then leave so colourful hips can form. If petals blowing around the garden bothers you, these can be removed leaving the base of the flower to form the hip. Hips are often overlooked in rose growing but provide colour and interest at a time when there is little else happening in the garden. If you have summer trimmed (usually done late January to early February), then continue to maintain moisture levels to keep the plants growing. Your reward will be a beautiful display of blooms in March and April. The autumn blooms tend to be smaller than those in spring but have more intense colouring and better substance. Summer trimming – for those who don’t know – is when all blooms and buds are removed from the plant, an application of fertiliser is provided and the plants are provided with sufficient water in order to get them growing again. The water and fertiliser are crucial as without them, growth will be stunted. Summer trimming is also a great way to try to get roses into bloom for a certain date although it is a bit of a lottery with moisture, temperature and nutrition all playing their part. ASSESSING PERFORMANCE Autumn is a great time to assess the performance of rose varieties in your garden. If the plant is in its first season, don’t be too hasty to discard – often plants need a year to properly settle in anyway. This is especially so for climbing roses, which often don’t start producing the long growths characteristic of them until the second year. Sometimes moving a rose can give it a new lease of life. May is a good month to move roses as usually there is plenty of moisture about.

If you are looking to plant some new roses, now is the time to order from garden centres and specialist nurseries, either by mail order or online. The new and popular varieties, along with those varieties grown on a standard, often sell out the quickest. Look around public rose gardens in your area to ee which varieties are performing well in your area. PREPARING NEW AREAS The autumn months are a great time for preparing new areas for roses. Dig over the area you are wanting to plant and fork in some compost or well-rotted animal manure. Add some lime or dolomite lime and a sprinkling of blood and bone and incorporate into the soil. Do not add any other fertiliser. Autumn is also a good time to check your soil pH, especially if your roses don’t seem to be doing as well as they should. The scale measures the acidity of the soil and ranges from 1: acidic, to 14: alkaline. Roses require a pH of between 6 and 6.9, with 6.5 being the optimum level. If the pH is higher or lower than this, nutrients in the soil are ‘locked up’ and cannot be used by the plant. If your roses are not thriving, then consider getting a soil test done to determine the pH of your garden and from that, corrective action can be taken to get the pH within range. CLEAN UP April and May are good months to have a good tidy up around your roses. Hygiene is important to prevent diseases, such as black spot and rust, from TRIMMABLE: Standard version of Iceberg before facing the secateurs. overwintering and infecting new growth in the spring, so all fallen leaves and debris needs to be picked up and disposed of in the rubbish. Don’t add to the compost. It can be a bit timeconsuming, but is well worth it. An old pair “of kitchen tongs is great for reaching difficult spots and also keeping your hands away from the thorns. You can continue to spray your roses for pests and diseases if you wish. Black spot has been more prevalent with the wetter summer weather this year, but other diseases such as rust and powdery mildew are also about, along with insect pests like aphids.
