PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The prime time to plant Alcea rosea ‘Chater’s Double Scarlet’ is in the spring when the soil warms up. Planting during this period allows the roots to establish before the peak growing season, resulting in robust growth and an impressive floral display.
Autumn: Alternatively, you can plant Alcea in early autumn. This gives the plant time to settle before dormancy, which can lead to stronger growth in the subsequent spring.
Site Selection
Sunlight: Alcea rosea ‘Chater’s Double Scarlet’ thrives in full sun. Select a location that receives at least 6 hours of direct sunlight each day to promote abundant flowering and healthy plant development.
Soil: Well-drained soil is essential for Alcea. This plant is sensitive to waterlogged conditions, so it’s crucial to ensure that the soil drains properly. Enhance drainage by mixing organic matter, such as compost or sand, into the planting area.
Planting Instructions
Prepare the Hole: When planting Alcea rosea ‘Chater’s Double Scarlet’, dig a hole that is twice the width and the same depth as the root ball. This will allow ample space for the roots to spread and establish themselves comfortably.
Soil Preparation: Mix in compost or organic matter with the existing soil to enhance its fertility and drainage capabilities. This Alcea will benefit from nutrient-rich soil, which supports vigorous growth and vibrant blooms.
Planting: Place the plant into the prepared hole, ensuring the top of the root ball is level with the surrounding soil surface. Gently backfill the hole, firming the soil around the roots to eliminate any air pockets.
Watering After Planting: Water Alcea rosea ‘Chater’s Double Scarlet’ thoroughly right after planting. This helps to settle the soil and encourages the roots to establish. Ensure the planting area drains well to avoid standing water.
Watering Requirements
Growing Season: Once established, Alcea rosea ‘Chater’s Double Scarlet’ exhibits good drought tolerance. Water moderately during dry spells, allowing the soil to dry out slightly between watering sessions. Avoid overwatering, as excessive moisture can lead to root rot.
Dormant Season: In the dormant season, reduce watering significantly. Water only if the soil becomes excessively dry, as Alcea requires minimal moisture during this time.
Feeding
Spring: In early spring, apply a balanced fertiliser to give Alcea rosea ‘Chater’s Double Scarlet’ a nutrient boost. This supports healthy new growth and vibrant flower production.
Mid-Summer: A light feeding in mid-summer will encourage continued flowering and help maintain the vigour of your Alcea throughout the blooming season.
Pruning
Deadheading: Regularly deadhead the plant by removing spent flowers. This practice prolongs the blooming period, keeps the plant tidy, and encourages the production of new flowers.
Autumn Pruning: After the last flowers fade in autumn, cut back Alcea rosea ‘Chater’s Double Scarlet’ to ground level. This prepares the plant for winter dormancy and promotes healthier growth in the following year.
Mulching
Spring: Apply mulch around the base of your Alcea in spring to retain soil moisture, suppress weeds, and regulate soil temperature. Organic mulches like bark chips or straw are highly effective.
Winter: In winter, apply a layer of mulch around the base to protect the roots from cold temperatures and prevent frost heaving. This practice ensures that your Alcea survives the winter and thrives in the next growing season.
Supporting the Plant
Staking: Alcea rosea ‘Chater’s Double Scarlet’ typically has sturdy stems. However, in particularly windy areas, consider staking to prevent potential damage to the plant.
Final Tips
Alcea rosea ‘Chater’s Double Scarlet’ is a low-maintenance perennial that adds vibrant colour and beauty to your garden throughout the growing season. By ensuring it has full sun and well-drained soil, along with adhering to these care instructions, this Alcea will reward you with stunning blooms from early summer to autumn.
