Geranium Rozanne, also known as Cranesbill, is a versatile plant that can be grown in both full sun and partial shade. However, for the best flowering and overall growth, it is recommended to provide it with full sun exposure.
In terms of soil conditions, Rozanne geranium prefers a moist but well-drained soil. This means that the soil should retain some moisture, but excess water should not accumulate around the roots, as this can lead to root rot and other problems. To achieve this balance, it is important to ensure that the soil has good drainage, allowing excess water to escape easily. Adding organic matter, such as compost, to the soil can improve its drainage capabilities and also enhance its moisture-retaining properties.
When it comes to sunlight requirements, Rozanne geraniums thrive in full sun conditions. This means that they should receive at least six hours of direct sunlight per day. The more sunlight they receive, the better their flowering performance will be. However, in regions with hot and intense afternoon sun, it is advisable to provide some afternoon shade to protect the plants from excessive heat and potential sunburn. This can be achieved by planting them near taller plants or using shade cloths or other shading techniques.
In warmer regions, providing afternoon shade becomes even more crucial to prevent the plants from suffering from heat stress. The intense heat can cause the leaves to wilt and the flowers to fade quickly. By providing some shade during the hottest part of the day, you can help keep the plants cool and ensure their overall health and vitality.
Personal experience has shown me that Rozanne geraniums planted in full sun tend to produce more blooms and have a more compact growth habit compared to those grown in partial shade. However, I have also successfully grown them in areas with dappled shade, and while they may not produce as many flowers, they still exhibit healthy growth and add color to the garden.
To summarize, Rozanne geraniums can tolerate both full sun and partial shade, but for the best flowering and overall growth, it is recommended to provide them with full sun exposure. However, in regions with hot afternoon sun, it is advisable to provide some afternoon shade to protect the plants from excessive heat. Regardless of the sun exposure, it is important to ensure that the soil is moist but well-drained to promote healthy root growth and prevent waterlogging issues.
