PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The optimal time to plant Cynara scolymus is in spring when the soil begins to warm. This allows the roots to establish firmly before the blooming season, resulting in a robust and healthy plant.
Autumn: Alternatively, you can plant Cynara scolymus in early autumn. This allows the plant to settle in before dormancy, encouraging better growth in the following spring.
Site Selection
Sunlight: Cynara scolymus thrives in full sun. Choose a location that receives at least 6 hours of direct sunlight each day for optimal growth and flower production.
Soil: Ensure well-drained soil for Cynara scolymus. The plant does not tolerate waterlogged conditions, so good drainage is essential for preventing root rot. Incorporate organic matter like compost to improve soil quality and drainage.
Planting Instructions
Prepare the Hole: When planting Cynara scolymus, dig a hole that is twice the width and the same depth as the root ball. This provides ample space for the roots to spread and grow comfortably.
Soil Preparation: Mix compost or organic matter into the soil to enhance fertility and drainage. Cynara scolymus benefits from nutrient-rich soil, promoting vigorous growth and vibrant blooms.
Planting: Place the plant into the prepared hole, ensuring that the top of the root ball is level with the surrounding soil. Gently backfill the hole, firming the soil to remove any air pockets.
Watering After Planting: Thoroughly water Cynara scolymus after planting. This helps to settle the soil and encourages the roots to establish. Ensure the area drains well to avoid waterlogged conditions.
Watering Requirements
Growing Season: Once established, Cynara scolymus is moderately drought-tolerant. Water during dry spells, allowing the soil to dry out slightly between sessions. Avoid overwatering, as excessive moisture can lead to root issues.
Dormant Season: During the dormant season, reduce watering significantly. Only water if the soil becomes excessively dry, as Cynara scolymus requires minimal moisture during this period.
Feeding
Spring: In early spring, apply a balanced fertiliser to give Cynara scolymus a strong start to the growing season. This will support healthy new growth and vibrant flowers. • Mid-Summer: A light feeding in mid-summer can encourage continued flowering and ensure that Cynara scolymus maintains its vigour throughout the blooming season.
Pruning
Deadheading: Regularly remove spent flowers from Cynara scolymus to prolong the blooming period, keep the plant tidy, and encourage new flower production.
Autumn Pruning: After the last flowers have faded in autumn, cut back the plant to ground level. This prepares the plant for winter dormancy and promotes healthier growth in the following year.
Mulching
Spring: Apply a layer of mulch around the base of Cynara scolymus in spring to retain soil moisture, suppress weeds, and regulate soil temperature. Use organic materials such as bark chips or compost for the best results.
Winter: In winter, adding mulch around the plant helps protect the roots from cold temperatures and prevents frost heaving, ensuring the plant survives through to the next growing season.
Supporting the Plant
Staking: Cynara scolymus has tall stems that may need staking, especially in windy locations, to prevent bending or breakage.
