Location

• Choosing a suitable site is the first step to a healthy rose bush. Plant roses in a site that offers at least six hours of direct sunlight each day, as well as good air circulation. Plants grown in shady situations will produce fewer flowers and are more susceptible to diseases. A location that offers both morning and afternoon sunlight is also suitable, especially if roses are being grown in a hot, southern climate.
  
  

Water

• Water deeply and regularly to establish a strong, deep root system that will help protect the rose from potential health problems. Water close to the soil, rather than from overhead, to avoid splashing the leaves and flowers. Wet leaves and flowers are more prone to catch air-borne fungal diseases. Watering in the morning, rather than the evening, gives the plant time to dry out before temperatures drop. Do not let the soil become bone dry, especially during the growing season.
  
  

Companion Plants

• Select heavily aromatic plants to cultivate near your rose bushes as these help to deter harmful pests. Plants that naturally repel pests include garlic and onion chives. Gardeners can also cultivate companion plants that will attract beneficial insects. Plants, such as coriander, dill and lucerne, attract beneficial insects, including parasitoid wasps and hoverflies. Lady bugs are also welcome additions to any garden and are available at most nurseries.
  
  

Mulch

• Mulch offers many benefits to roses as it helps to retain moisture in the soil and regulate temperature. Mulch also helps to suppress weeds which, in turn, prevents potential damage to the rose's shallow roots. Mulch with a thin layer of organic material, such as hay, shredded bark or dry grass clippings. Enhance the soil by feeding roses with manure or compost, and spray seaweed on the leaves to give the plant additional nutrients.
