Miniature roses thrive in full sun. Foliage and flowers will become sparse in shady conditions.
Roses like a rich, well-drained, loamy soil.
How much water your rose bush will require depends on your soil and weather. A general rule of thumb is to provide at least 1 inch of water each week. During hot, dry spells you will need to water more frequently. Be sure to water deeply, so that the soil is wet at least 12 to 18 inches below the surface.
Avoid getting the leaves wet during humid weather to discourage fungal diseases.
Temperature and Humidity
Although mini roses do quite well in containers and you often see them sold as houseplants, many gardeners are disappointed by their performance indoors. Like roses, they need full sun and medium humidity.
These are easy enough to provide in summer, but humidity drops considerably when the heat comes on indoors and roses will quickly become desiccated. Mini roses given as gifts will do best if transplanted outdoors
Roses can be heavy feeders and since mini roses continue blooming all season, regular fertilizing is essential. Use any commercial rose food or general-purpose fertilizer, according to label instructions. To keep your plant healthy:
- Feed when the bush first leafs-out.
- Feed after each heavy flush of bloom.
- Stop feeding about 6 to 8 weeks before the first expected frost to discourage new growth that could be killed back during winter.
