Abstract
For at least 10 years the survival of 'old' roses (principally Chinas, Teas, Bourbons and Noisettes) grown on their own roots has been assessed in the oolitic limestone soil of south Miami-Dade. An organically enriched soil was used as backfill, the plants mulched with pine bark nuggets, and a complete slow release fertilizer applied every 3 months. After 10 years, of the 27 cultivars planted, 6 out of 8 China roses were thriving, plus 5 out of 9 Teas and both Noisettes. 'Maggie' apart (a putative Bourbon), the other 3 roses in this class were disappointing. 'Cecile Brunner' and a found rose (probably' spray Cecile Brunner') bloomed well and presented few problems. Over the period of the study no insecticides or fungicides were used. Regular maintenance consisted of deadheading and pruning to remove diseased or dead canes. It is concluded that Tea, China and Noisette roses should be considered viable options as specimen shrubs in Miami-Dade landscapes.
