Soil Requirements
The Hieracium scabriusculum Schwein. var. saximontanum Lepage grows best in well-draining soil that is slightly acidic to neutral. The ideal pH range for the plant is between 6.0 and 7.0. Avoid heavy, wet soils or those prone to waterlogging. Add organic matter such as compost, leaf mold or aged manure to the soil to improve drainage and nutrient content.
Cultivation Methods
Hieracium scabriusculum Schwein. var. saximontanum Lepage, commonly known as rough hawkweed or alpine hawkweed, is a perennial herbaceous plant that grows in rocky or gravelly soils. To cultivate this plant, it is essential to ensure that the soil is adequately drained. It is relatively easy to maintain, and it does well in both full sun and partial shade. The ideal temperature range for this plant is between 13 and 21 degrees Celsius.
Watering Needs
This plant requires moderate watering. The best time to water it is in the morning when the weather is cooler. This allows the water to penetrate deep into the soil, providing vital nutrients to the roots. Avoid watering it during the hottest part of the day, as this can cause the water to evaporate quickly.
Fertilization
Hieracium scabriusculum does not need fertilization. If you want to enhance its growth, you can add some organic matter to the soil. Organic matter is a great source of nutrients that can help improve soil structure and water-holding capacity. However, be careful not to add too much compost, as this can lead to the accumulation of salts in the soil, which can damage the roots of the plant.
Pruning
Pruning is not necessary for this plant. However, you can remove any faded flowers to encourage the growth of new ones. This plant is known to spread, so you may need to divide it every so often to prevent overcrowding. Divide it in the spring or fall when the plant is dormant.
