PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: The best time to plant is during spring, when the soil begins to warm. This allows the roots of Symphyotrichum ‘Little Carlow’ to establish before the growing season starts, giving the plant a strong foundation for healthy growth.
• Autumn: Alternatively, plant in early autumn. This gives the plant time to settle in before the colder months, encouraging stronger growth in the following spring.

Site Selection

• Sunlight: Symphyotrichum (Aster)  ‘Little Carlow’ thrives in full sun to partial shade. Choose a location that receives at least 4-6 hours of sunlight daily. Full sun promotes stronger flowering, while partial shade is suitable for hot climates.
• Soil: Ensure the soil is well-drained for Symphyotrichum ‘Little Carlow’. This plant does not like to sit in waterlogged soil, as this can lead to root rot. Incorporating organic matter like compost will improve soil fertility and drainage.

Planting Instructions

1. Prepare the Hole: Dig a hole about twice the width and the same depth as the root ball of the plant. This allows the roots to spread and establish without restriction.
2. Soil Preparation: Mix compost or well-rotted organic matter into the soil to improve its texture and fertility. Symphyotrichum (Aster) ‘Little Carlow’ thrives in nutrient-rich soil.
3. Planting: Place the root ball into the prepared hole, ensuring that the top of the root ball is level with the surrounding soil surface. Gently backfill the hole, pressing the soil down to eliminate any air pockets.
4. Watering After Planting: Water thoroughly after planting to help settle the soil and encourage root establishment. Make sure the area has good drainage to prevent waterlogging.

Watering Requirements

• Growing Season: Once established, Symphyotrichum ‘Little Carlow’ is relatively drought-tolerant. However, during dry spells, it’s best to water regularly to keep the soil moderately moist. Avoid overwatering, as the plant does not like to have soggy roots.
• Dormant Season: During the winter months, reduce watering significantly, as Symphyotrichum ‘Little Carlow’ requires less moisture during this time. Only water if the soil becomes excessively dry.

Feeding

• Spring: Apply a balanced, slow-release fertiliser in spring to support the early growth of Symphyotrichum ‘Little Carlow’. This will provide essential nutrients for healthy leaves and flowers.
• Mid-Summer: A light application of fertiliser in mid-summer can help promote continued blooming and ensure the plant stays strong throughout the growing season.

Pruning

• Deadheading: Regularly remove spent flowers from Symphyotrichum (Aster) ‘Little Carlow’. This not only keeps the plant tidy but also encourages continuous flowering throughout the season.
• Autumn Pruning: After the final blooms of the season have faded, cut the plant back to the ground. This will prepare it for dormancy and encourage vigorous growth the following spring.

Mulching

• Spring: Apply a layer of mulch around the base to retain moisture, suppress weeds, and regulate soil temperature. Organic mulches, such as bark chips or compost, work best.
• Winter: Add a layer of mulch in the winter to protect the roots from extreme cold and prevent frost heaving. This will help the plant survive through the colder months.

Supporting the Plant

• Staking: Symphyotrichum (Aster) ‘Little Carlow’ has a tall and upright growth habit, so staking may be necessary, especially in windy conditions. Use lightweight plant supports to help keep the plant upright and prevent any damage from wind or heavy rain.
