Noble geraniums (bot. Pelargonium grandiflorum) are popular bedding and balcony plants, but are also suitable for indoor cultivation. Unlike other types of geranium, they are not hardy and do not tolerate cold, strong winds or constant rain.
Noble geraniums are very thirsty ornamental plants
location and soil
The more sun your noble geraniums get, the more profusely they will bloom. A sunny location is therefore recommended, outside or in the living room or conservatory. However, protect noble geraniums from the blazing sun at midday when the plants are on the windowsill. Temperatures between around 20 °C are ideal.
Noble geraniums can also feel very comfortable on a balcony. Here, however, they should be given a place that is protected from the wind and rain. Strong winds break their shoots, while rain damages the colorful flowers, which then easily stick together.
A humic, permeable and slightly acidic soil is very beneficial for noble geraniums. They tolerate neither lime nor waterlogging. A pH between 5.5 and 6.5 is ideal. For pot planting, use special geranium soil or high-quality compost-based eder instead of cheap potting soil, your precious geraniums will thank you.
Plant noble geraniums
You can buy noble geraniums in the garden center as early as March. But it's still too early to plant. Instead, plant in tubs, pots or balcony boxes (€109.00) and then place the geraniums in a warm, sunny spot. After the ice saints, your precious geraniums can go outside. Gradual acclimatization to the cooler environment is recommended.
Water and fertilize
Noble geraniums have a fairly high water and nutrient requirement. Therefore, they should be watered and fertilized regularly. Be sure to consider the low lime tolerance of these plants. Rainwater or stagnant tap water are ideal for watering.

- Soil: sandy to loamy, fresh or slightly moist, slightly acidic
- Flowering time: from April to October
- Flower color: white, pink, red, violet, also multicolored
- relatively high water and nutrient requirements
- perennial, but not hardy
