PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: Plant Delphinium ‘Paramo Blanco’ in spring once the soil begins to warm. This early start encourages strong root development and a robust flower display by summer.
Autumn: You can also plant your Delphinium in early autumn. This allows the plant to establish before winter dormancy, promoting healthy growth in the following season.
Site Selection
Sunlight: Choose a sunny position for Delphinium ‘Paramo Blanco’. It thrives in full sun, producing its most vibrant blooms when it receives at least six hours of direct light each day.
Soil: Delphinium prefers fertile, moist, and well-drained soil. Avoid overly wet or compacted areas. Improve poor soils by adding compost or well-rotted organic matter to enhance structure and drainage.
Planting Instructions
Prepare the Site: Dig a hole twice the width and equal depth of the root ball. This gives Delphinium ‘Paramo Blanco’ room to establish a strong foundation.
Improve the Soil: Enrich the soil with compost or a balanced slow-release fertiliser before planting. This provides nutrients that will support healthy growth and flowering.
Planting: Place the plant in the hole so the crown is just at soil level. Gently firm the soil around the base to eliminate air pockets.
Watering In: Water thoroughly after planting to help settle the soil around the roots of your Delphinium.
Watering Requirements
Growing Season: Water your Delphinium regularly during dry spells. Keep the soil evenly moist, especially during bud formation and flowering. Avoid overhead watering to prevent fungal issues.
Dormant Season: During late autumn and winter, reduce watering. Ensure the area does not remain waterlogged to protect the roots from rot.
Feeding
Early Spring: Feed Delphinium ‘Paramo Blanco’ with a balanced fertiliser as new shoots emerge. This kickstarts growth and supports flower spike development.
Mid-Summer: Apply a second round of feed after the first flush of flowers. This may encourage a lighter second bloom in late summer or early autumn.
Staking and Support
Delphinium ‘Paramo Blanco’ produces tall flower spikes that benefit from support. Use canes or a ring support system when the plant reaches around 30cm in height to keep the stems upright and prevent wind damage.
Pruning and Deadheading
Deadheading: Remove faded flower spikes promptly to maintain a tidy appearance and potentially encourage repeat flowering.
Cutting Back: In late autumn, cut the stems of your Delphinium to just above ground level. This prepares the plant for dormancy and encourages fresh growth the next spring.
Mulching
Spring Mulch: Apply a layer of organic mulch around the base of Delphinium ‘Paramo Blanco’ to retain moisture, suppress weeds, and regulate soil temperature.
Winter Protection: Add extra mulch in colder months to insulate the crown and protect the roots from frost.
Final Tips
Delphinium ‘Paramo Blanco’ is a showstopping addition to borders and makes an excellent choice for cottage gardens and formal beds alike. With consistent care—especially staking, feeding, and watering—you’ll enjoy tall, elegant spires of white blooms from May through July. Incorporate this Delphinium into your planting plan for a dramatic vertical accent that draws both the eye and pollinators to your garden.
