Care Instructions:

Tradescantia (Andersoniana Group) ‘Concord Grape’, commonly known as Spiderwort, is a striking perennial plant noted for its deep purple flowers and graceful, arching green foliage. This variety blooms profusely from late spring through summer, adding a vibrant splash of color to gardens, borders, and containers. ‘Concord Grape’ is an easy-to-care-for plant that thrives in partial shade to full sun, making it a versatile choice for a variety of garden settings.

Light

‘Concord Grape’ Spiderwort thrives in partial shade to full sun. For optimal flowering and rich foliage color, place it in a location where it receives morning sunlight and afternoon shade. It can tolerate full sun, particularly in cooler climates, but too much direct sunlight in hotter regions may cause leaf scorch.

Water

Water your ‘Concord Grape’ Spiderwort regularly, keeping the soil consistently moist but not waterlogged. During the growing season (spring and summer), ensure the soil remains evenly moist, especially during dry periods. In the fall and winter, reduce watering slightly, allowing the top inch of soil to dry out between waterings. Avoid overwatering, as this can lead to root rot.

Soil

‘Concord Grape’ Spiderwort prefers well-draining, fertile soil. A loamy or sandy soil mix with good organic content is ideal. If your garden soil is heavy or clay-based, consider amending it with compost or sand to improve drainage and aeration. This plant adapts well to various soil types as long as proper drainage is provided.

Temperature

The optimal temperature range for ‘Concord Grape’ Spiderwort is between 60°F and 80°F (16°C to 27°C). It is hardy in USDA zones 4-9, making it suitable for a variety of climates, including areas with light frost. In colder regions, the plant may die back to the ground in winter but will typically reemerge in the spring.

Humidity

‘Concord Grape’ Spiderwort prefers moderate to high humidity levels but can tolerate a range of humidity conditions. If grown indoors or in a dry climate, occasional misting can help maintain humidity and keep the foliage looking lush. Ensure good air circulation around the plant to prevent fungal issues, especially in high humidity environments.

Fertilizer

Feed your ‘Concord Grape’ Spiderwort with a balanced, water-soluble fertilizer every 4-6 weeks during the growing season (spring through early fall). Regular feeding encourages healthy growth and abundant flowering. Reduce feeding in the fall and winter when the plant’s growth naturally slows down. Over-fertilizing can lead to excessive foliage growth at the expense of flowers, so be careful not to overdo it.

Best Placement Ideas

• Garden Borders: ‘Concord Grape’ Spiderwort is ideal for garden borders, where its vibrant purple flowers can create a striking contrast against green foliage. It pairs well with other perennials for a lush, colorful garden bed.
• Containers: This plant thrives in containers, where its upright habit and rich-colored flowers can add interest to patios, balconies, or entryways. Ensure the container has good drainage, and place it in a spot with partial shade for the best results.
• Woodland Gardens: ‘Concord Grape’ Spiderwort is perfect for woodland gardens, where it can thrive under the dappled shade of trees. Its deep purple flowers provide a beautiful contrast to the green foliage of surrounding plants.

Common Issues

Pests: ‘Concord Grape’ Spiderwort is generally resistant to pests but can occasionally attract spider mites, aphids, or slugs. Regularly inspect the leaves for any signs of pests, such as sticky residue, webbing, or small insects. Treat infestations promptly with insecticidal soap or neem oil to prevent them from spreading.

Diseases: Overwatering or poor air circulation can lead to fungal diseases, such as root rot or leaf spot. Ensure the soil is well-draining and avoid letting the plant sit in water. If you notice yellowing leaves, mushy roots, or dark spots, it may indicate a fungal issue. Improve air circulation and avoid overhead watering to help prevent these problems.

Things to Watch Out For

Watch for signs of stress, such as yellowing or browning leaves, which may indicate improper watering, low humidity, or inadequate light. If the plant’s growth slows or the leaves start to lose their vibrant color, consider adjusting its care routine to better meet its needs. Additionally, ‘Concord Grape’ Spiderwort can become leggy if it doesn’t receive enough light, so regular pruning may be necessary to keep it looking full and healthy.

Propagation Tips

Propagation Method: ‘Concord Grape’ Spiderwort is easily propagated through division or stem cuttings. To propagate by division, dig up the plant in early spring or fall and carefully separate the clumps into smaller sections, each with roots attached. Replant the divisions at the same depth as the original plant. To propagate by cuttings, take a 4-6 inch cutting from a healthy stem, remove the lower leaves, and place the cutting in water or directly into moist soil. Roots should develop within a few weeks, and the new plant can then be transplanted into its own pot.

Best Time to Propagate: The best time to propagate ‘Concord Grape’ Spiderwort is in the spring or early summer when the plant is actively growing. This timing allows the new plants to establish roots and grow during the most favorable conditions.

Maintenance Tips

Pruning: Pruning your ‘Concord Grape’ Spiderwort involves trimming back any leggy or unruly stems to maintain its appearance and encourage bushier growth. Regular pruning helps control the plant’s size and shape and can also stimulate more vigorous growth. Use clean, sharp scissors or pruning shears to avoid damaging the plant.

Repotting: ‘Concord Grape’ Spiderwort should be repotted every 1-2 years or when it outgrows its current container. Choose a slightly larger pot with fresh, well-draining soil. Repotting is best done in early spring before the growing season begins to give the plant time to adjust.
