PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: The ideal time to plant is during the spring when the soil begins to warm. Planting at this time allows the roots to establish themselves before the blooming season begins. This gives your plant plenty of time to develop its unique, fragrant flowers.
• Autumn: You can also plant in early autumn. This timing helps the plant settle in before dormancy, ensuring stronger growth come spring. However, ensure that you protect the plant from colder temperatures if you choose to plant in the autumn.

Site Selection

• Sunlight: This plant thrives in full sun. Choose a location that receives at least 6 hours of direct sunlight daily for the best growth and flower production. With enough sunlight, the plant will produce stunning flowers throughout the growing season.
• Soil: Well-drained, moist soil is essential for this plant. It does not tolerate waterlogged conditions, so ensure that the soil drains well to prevent root rot. Mixing in organic matter like compost improves soil quality and drainage, promoting a healthy root system.

Planting Instructions

1. Prepare the Hole: Dig a hole that is twice the width and depth of the root ball. This ensures that the roots have enough space to spread and establish a strong foundation.
2. Soil Preparation: Enrich the soil with compost or organic matter to improve its fertility and drainage. The plant thrives in nutrient-rich soil, which helps support healthy growth and vibrant blooms.
3. Planting: Place the plant in the hole, making sure the top of the root ball is level with the surrounding soil. Gently backfill the hole with soil and firm it down to eliminate any air pockets.
4. Watering After Planting: After planting, thoroughly water the plant. This helps settle the soil around the roots and encourages them to establish. Ensure that the planting area drains well to avoid any waterlogging.

Watering Requirements

• Growing Season: The plant enjoys consistently moist soil but dislikes being overwatered. During dry spells, water regularly, allowing the soil to dry out slightly between waterings. Avoid standing water, as excessive moisture can lead to root rot.
• Dormant Season: During the dormant period, reduce watering significantly. The plant requires minimal moisture during the cooler months. Only water if the soil becomes excessively dry, as this will help prevent root damage.

Feeding

• Spring: Early in the growing season, apply a balanced, slow-release fertiliser to give the plant a strong start. This will support healthy foliage growth and vibrant flower production as the season progresses.
• Mid-Summer: A light feeding in mid-summer can help promote continued flowering throughout the growing season. Avoid excessive fertilisation, as this can result in lush foliage growth at the expense of blooms.

Pruning

• Deadheading: Regularly deadhead the plant by removing spent flowers. This encourages new blooms and keeps the plant looking tidy. Deadheading also helps the plant focus its energy on producing fresh flowers rather than seed production.
• Autumn Pruning: After the last flowers have faded in autumn, cut back the plant to ground level. This prepares the plant for the dormant period and ensures that it has a healthy start the following spring.

Mulching Around the Plant

• Spring Mulching: Apply a layer of mulch around the base of your Cosmos atrosanguineus ‘Cherry Chocolate’. Mulch helps retain soil moisture, suppress weeds, and regulate soil temperature. Organic mulches like bark chips or compost are ideal for this plant.
• Winter Protection: During the winter months, add an extra layer of mulch around your plant to help protect the roots from cold temperatures. This will prevent frost heaving and provide insulation for the plant.

Supporting the Plant

• Staking: The plant is compact, so staking is usually not required. However, if grown in containers or in windy areas, consider using a small stake to prevent the plant from tipping over and to support its growth.
