Garden Advice Notes
Sanguisorba tanna, also known as Korean burnet, is a herbaceous perennial plant that belongs to the rose family (Rosaceae). It is native to East Asia, particularly Korea and China, and is commonly found in moist meadows, along streams, and in mountainous areas.
The plant has a clumping habit and can reach a height of about 60-90 cm (24-36 inches) with a spread of about 30-45 cm (12-18 inches). It produces pinnate, dark green leaves that are divided into small leaflets, and small, cylindrical flower spikes that can range in color from pink to deep red.
Soil type-Sanguisorba tanna prefers moist, well-drained soil that is rich in organic matter. It can tolerate a range of soil types, including loam, sandy loam, and clay soils, as long as the soil is not waterlogged or overly dry.
Ideally, the soil pH should be slightly acidic to neutral, with a pH range of 6.0 to 7.5. If the soil is too acidic, adding lime can help to raise the pH.
It is also important to ensure that the soil is adequately moist, particularly during the growing season. Sanguisorba tanna prefers soil that is consistently moist, but not waterlogged, so it is important to avoid planting it in areas that are prone to waterlogging or where the soil is excessively heavy or compacted.
Overall, providing well-drained, fertile soil with consistent moisture is key to growing healthy and vigorous Sanguisorba tanna plants.
Location-Sanguisorba tanna prefers a partially shaded to fully shaded location. It is tolerant of full sun in cooler climates, but in hotter climates, it may require some shade to prevent wilting and stress.
It is important to avoid planting Sanguisorba tanna in areas that receive direct, intense sunlight for prolonged periods of time, as this can lead to leaf scorch and other stress-related problems.
In terms of climate, Sanguisorba tanna is generally tolerant of a range of temperatures, but it prefers cooler temperatures and may struggle in hot, dry climates. It is also important to ensure that the plant is protected from strong winds, as this can damage the foliage and flowers.
Overall, a partially shaded to fully shaded location with moderate temperatures and protection from strong winds is ideal for growing healthy and vigorous Sanguisorba tanna plants.
Pest and disease problems-Sanguisorba tanna is generally considered to be a low-maintenance plant and is not particularly prone to pest or disease problems. However, like all plants, it may be susceptible to certain issues under certain conditions. Here are a few of the potential pest and disease problems that Sanguisorba tanna may face:
- Powdery mildew: This is a fungal disease that can cause a white, powdery coating on the leaves and stems. It is most common in humid conditions and can be prevented by providing good air circulation and avoiding overhead watering.
- Rust: Rust is another fungal disease that can cause orange or reddish-brown spots on the leaves. It is also more common in humid conditions and can be prevented by providing good air circulation and avoiding overhead watering.
- Aphids: Aphids are small, sap-sucking insects that can cause stunted growth and distorted leaves. They can be controlled with insecticidal soap or neem oil.
- Slugs and snails: Slugs and snails can feed on the foliage and leave behind slimy trails. They can be controlled with slug and snail bait or by handpicking them off the plant.
Overall, Sanguisorba tanna is a relatively hardy and disease-resistant plant, but keeping it healthy with good cultural practices such as proper watering, good air circulation, and regular fertilization can help prevent pest and disease problems.
- Seed propagation: Sanguisorba tanna can be propagated from seed, which should be sown in the spring or fall. The seeds should be lightly covered with soil and kept moist until germination occurs, which usually takes around 2-4 weeks. Once the seedlings have grown large enough to handle, they can be transplanted into individual pots or directly into the garden.
- Division: Sanguisorba tanna can be propagated by division in the spring or fall. This involves digging up the plant and separating it into smaller clumps, each with their own roots and foliage. These clumps can then be replanted in their new location and watered well.
- Cuttings: Sanguisorba tanna can also be propagated by taking stem cuttings in the summer. The cuttings should be around 10 cm (4 inches) long and should be taken from healthy, mature stems. These cuttings can be rooted in moist soil or a rooting hormone and then transplanted once they have developed roots.
Overall, Sanguisorba tanna is a relatively easy plant to propagate, and each of these propagation methods can be successful with the proper care and attention.
Pruning, cutting back and dividing-Sanguisorba tanna benefits from regular pruning and cutting back to promote new growth and maintain its shape. Division can also be done periodically to control its size and promote healthier growth. Here are some details on each of these tasks:
- Pruning: Sanguisorba tanna benefits from regular pruning, which should be done in the spring before new growth appears. This involves cutting back any dead or damaged stems, as well as removing any weak or overcrowded growth. Pruning can also be done throughout the growing season to promote bushier growth and prevent the plant from becoming too leggy.
- Cutting back: Sanguisorba tanna can also be cut back hard after flowering to encourage new growth and prolong its flowering period. This involves cutting back the entire plant by about half, just above a node or leaf.
- Division: Sanguisorba tanna can become quite large over time, and dividing the plant every few years can help to control its size and promote healthier growth. Division should be done in the spring or fall and involves digging up the plant and separating it into smaller clumps, each with their own roots and foliage.
Overall, regular pruning and cutting back can help to keep Sanguisorba tanna healthy and looking its best, while division can help to promote healthier growth and prevent the plant from becoming too large and overcrowded.
