Description

Alcea rosea ‘Chater’s Double White’ is a stunning perennial known for its beautiful, fully double white flowers that can bring elegance and charm to any garden. Here’s a comprehensive guide on how to plant and care for Alcea to ensure its thriving growth.

Best Planting Time

• Spring: The optimal time to plant Alcea rosea ‘Chater’s Double White’ is in spring when the soil starts to warm up. Planting during this season allows the roots to establish before the flowering season, ensuring a robust plant.
• Autumn: Alternatively, you can also plant your Alcea in early autumn. This timing allows the plant to settle in before going dormant, resulting in better growth the following spring.

Site Selection

• Sunlight: Alcea rosea ‘Chater’s Double White’ thrives in full sun. Select a location that receives at least 6 hours of direct sunlight each day to promote continuous flowering and maintain the plant’s health.
• Soil: Choose well-drained soil for Alcea. This plant does not tolerate waterlogged conditions, so ensuring proper drainage is essential to prevent root rot. You can enhance drainage by incorporating organic matter, such as compost or grit, into the soil.

Planting Instructions

1. Prepare the Hole: When planting your Alcea, 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 comfortably.
2. Soil Preparation: Mix compost or other organic matter with the soil to enhance fertility and drainage. Alcea benefits from nutrient-rich soil, promoting vigorous growth and abundant blooms.
3. 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.
4. Watering After Planting: Water Alcea rosea ‘Chater’s Double White’ thoroughly after planting. This helps settle the soil and encourages the roots to establish. Be mindful to ensure good drainage to avoid waterlogged conditions.

Watering Requirements

• Growing Season: Once established, Alcea rosea ‘Chater’s Double White’ is moderately drought-tolerant. Water during dry spells, allowing the soil to dry slightly between watering sessions. Avoid overwatering, as excess moisture can lead to root issues.
• Dormant Season: During the dormant season, reduce watering significantly. Only water if the soil becomes excessively dry, as Alcea requires minimal water during this time.

Feeding

• Spring: In early spring, apply a balanced fertiliser to give your Alcea a strong start to the growing season. This supports healthy new growth and vibrant blooms.
• Mid-Summer: A light feeding in mid-summer will encourage continued flowering and ensure that your Alcea  maintains its vigor throughout the blooming season.

Pruning

• Deadheading: Regularly deadhead Alcea rosea ‘Chater’s Double White’ by removing spent flowers. This prolongs the blooming period, keeps the plant tidy, and encourages 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 mulch around the base of the plant in spring to retain soil moisture, suppress weeds, and regulate soil temperature. Organic mulch, such as bark chips or compost, is recommended.
• Winter: In winter, apply mulch around the base of your Alcea to protect the roots from cold temperatures and prevent frost heaving. This ensures the plant survives through to the next growing season.

Supporting the Plant

• Staking: Alcea rosea ‘Chater’s Double White’ typically has sturdy stems, so staking is rarely necessary. However, in particularly windy areas, staking may help prevent damage to the plant.
