Buphthalmum salicifolium L. prefers full sun to partial shade. It requires a minimum of six hours of direct sunlight daily to grow and thrive. Insufficient light will result in poor growth and development.
Temperature Requirements
The ideal temperature range for Buphthalmum salicifolium L. growth is between 15°C to 25°C. This plant can grow in a variety of climates but prefers a mild temperature. Buphthalmum salicifolium L. can tolerate frosts and temperatures down to -10°C during the dormant winter period.
Soil Requirements
Buphthalmum salicifolium L. prefers well-drained soil with good organic matter content. This plant can tolerate a wide range of soil pH, from slightly acidic to slightly alkaline. The ideal pH for growth is between 6.0 to 7.5. The soil should be kept moist but not wet, as waterlogged soil can lead to root damage and plant death.
Cultivation Methods for Buphthalmum salicifolium L.
Buphthalmum salicifolium L., commonly known as Willow-leaved Oxeye Daisy, thrives well in well-draining soils, rich in organic matter. It prefers full sun but can tolerate light shade in the hottest part of the day. Start by preparing the planting site by loosening the soil, clearing debris and weeds, and adding compost or aged manure.
You can grow Buphthalmum salicifolium L. from seeds, which you can start indoors 4-6 weeks before the last frost. Alternatively, you can plant them directly into the prepared bed in the spring or autumn. Cover the seeds with a light soil layer and keep them moist but not waterlogged until they germinate, which usually takes 14-21 days. Once established, they are easy to grow and require minimal maintenance.
Watering Needs for Buphthalmum salicifolium L.
Buphthalmum salicifolium L. requires regular watering, especially during the growing season, to keep the soil slightly moist. This plant is susceptible to root rot if left in soggy soils, so it's essential to ensure adequate drainage. Avoid overwatering by allowing the soil to dry slightly between watering sessions. In periods of drought, ensure the plant receives at least an inch of water per week.
Fertilization for Buphthalmum salicifolium L.
Unlike other plants, Buphthalmum salicifolium L. doesn't require much fertilizer, and over-fertilizing can result in leggy growth and reduced flowering. However, if the soil lacks organic matter, you can apply a balanced, slow-release fertilizer at the start of the growing season. Otherwise, mix compost or aged manure into the upper soil layer before planting.
Pruning Buphthalmum salicifolium L.
Buphthalmum salicifolium L. is a low-maintenance plant that doesn't require pruning. However, it's beneficial to deadhead the spent flowers once they start to fade to promote prolonged flowering and maintain an attractive appearance. Cut back the stems by a third in autumn after the flowering season has ended to promote healthy growth and prevent leggy shoots.
Propagation of Buphthalmum salicifolium L.
Buphthalmum salicifolium L., commonly known as Willowleaf Oxeye, can be propagated via seed, division, and stem cuttings.
Propagation by Seed
The easiest way to propagate Buphthalmum salicifolium L. is through seeds. The seeds should be planted in the spring or fall when the soil temperature is above 50°F. The seeds require light to germinate, so they should be placed on the surface of the soil and barely covered. The soil should be kept moist until the seeds have germinated, which usually takes 1 to 2 weeks. The seedlings should be transplanted when they are large enough to handle, usually after 8 to 10 weeks.
Propagation by Division
Buphthalmum salicifolium L. can also be propagated through division. In the spring or fall, the plant can be carefully dug up and divided into smaller sections. Each section should have a portion of the root system and at least one shoot. The divided sections should be replanted at the same depth as the parent plant and watered thoroughly.
Propagation by Stem Cuttings
Propagation by stem cuttings is another option for propagating Buphthalmum salicifolium L. The stem cuttings should be taken from the parent plant in the early summer. The cuttings should be 3-4 inches long and include a few leaves. The lower leaves on the stem should be removed, and the cuttings should be planted in a well-draining propagation mix. The cuttings should be kept in a bright, warm location and misted regularly until they have rooted. Once rooted, they can be transplanted to their final location.
Disease and Pest Management for Buphthalmum salicifolium L.
Buphthalmum salicifolium L., commonly called the willow-leaved oxeye, is a robust and easy-to-grow perennial that belongs to the Asteraceae family. This plant is relatively sturdy and resistant to many pests and diseases, but it can still fall victim to certain issues if proper care is not taken.
Common Diseases
One of the common diseases that affect Buphthalmum salicifolium L. is powdery mildew. Powdery mildew is a fungal disease that appears as a white or gray powdery coating on the leaves, stems, and flowers of the plant. To manage this disease, it is advisable to remove the affected parts of the plant and spray a fungicide on the remaining foliage.
Another disease that might affect this plant is rust, which also presents as a powdery coating, but with a yellow or orange hue. Rust can cause the leaves to turn yellow and fall off the plant. To manage rust, remove the affected parts of the plant immediately and spray with a fungicide.
Common Pests
Buphthalmum salicifolium L. is relatively resistant to most pests. However, it can still be affected by aphids, spider mites, and slugs. Aphids and spider mites are the most common pests that bother this plant, especially if it is grown in dry and warm conditions.
To manage aphids and spider mites, spray the foliage with water or a solution of neem oil and water. Slugs, on the other hand, feed on the leaves and can cause significant damage to the plant. To control slugs, use a bait that contains iron phosphate, which is safe for humans and pets.
In conclusion, Buphthalmum salicifolium L. is a sturdy and resilient plant that can withstand most pests and diseases. However, it is essential to keep an eye on the plant and take necessary precautions to avoid any potential issues.
