Gardening guidance focuses on rose maintenance, disease management, and selecting plants capable of withstanding heatwaves or drought. To prevent bud rot caused by Botrytis cinerea, it is recommended to prune affected buds back to healthy wood. 

For climate resilience, the use of perennials such as Coreopsis or poppies is suggested to reduce water needs. Roses can also be cultivated in containers on balconies or terraces if planted in deep pots with adequate drainage and five to six hours of daily sunlight.

Managing fungal issues is a key priority. To combat powdery mildew, which thrives in warm days and cool, humid nights, gardeners are advised to avoid over-fertilizing with nitrogen, ensure adequate sunlight, and water at the roots. Natural treatments include spraying a mixture of baking soda and water or diluted milk. To prevent the spread of infections, diseased plant parts should be removed and disposed of in mixed waste rather than compost. For black spot, removing fallen leaves and debris is essential to eliminate overwintering sites. 

Additional strategies include planting borage near rose bushes to protect against pests like aphids. For year-round ornamental value, Cornus alba (dogwood) is recommended as a hardy, frost-resistant shrub that provides seasonal interest through its flowers, foliage, and colorful winter branches.
