PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The optimal time to plant Geranium pratense ‘Striatum’ is in spring. Planting during this period allows roots to establish before the peak flowering season, ensuring healthy growth and abundant blooms.
Autumn: Early autumn is also suitable. Planting at this time helps Geranium pratense ‘Striatum’ settle in before dormancy, encouraging strong growth the following year.
Site Selection
Sunlight: Geranium pratense ‘Striatum’ flourishes in full sun to partial shade. Choose a site that receives at least 4–6 hours of sunlight per day for optimal flower production.
Soil: Ensure well-drained soil for Geranium pratense ‘Striatum’. Adding organic matter such as compost improves fertility and supports vigorous growth while preventing root problems.
Planting Instructions
Prepare the Hole: Dig a hole twice the width and the same depth as the root ball to provide adequate space for root expansion.
Soil Preparation: Mix in compost or well-rotted organic matter to improve soil structure and nutrient content.
Planting: Position your Geranium so the top of the root ball is level with the surrounding soil. Backfill gently, firming the soil to remove air pockets.
Watering After Planting: Water thoroughly after planting to help the roots settle and encourage strong establishment.
Watering Requirements
Growing Season: Keep soil evenly moist during the first growing season while Geranium pratense ‘Striatum’ establishes. Once mature, it tolerates occasional dry periods but benefits from regular watering in prolonged dry spells.
Dormant Season: Reduce watering as growth slows. Only water if the soil becomes very dry.
Feeding
Spring: Apply a balanced, slow-release fertiliser in early spring to promote strong foliage and abundant flowering.
Mid-Summer: A light feed can extend flowering and maintain the plant’s vigour through the blooming season.
Pruning
Deadheading: Remove spent flowers regularly to encourage more blooms and maintain a tidy appearance.
Autumn Pruning: After flowering ends, cut back stems to tidy the plant and prepare Geranium pratense ‘Striatum’ for the dormant season.
Mulching
Spring: Apply mulch around the base of Geranium pratense ‘Striatum’ to conserve moisture, suppress weeds, and regulate soil temperature.
Winter: A mulch layer also protects roots during colder months, ensuring the plant survives and thrives in the next growing season.
Supporting the Plant
Geranium pratense ‘Striatum’ naturally forms a compact mound, so staking is usually unnecessary. In exposed or windy locations, light support can prevent flopping.
