WaterThe Himalayan Fleece Flower requires consistent moisture, so water it regularly to keep the soil evenly moist without being waterlogged. During the growing season, especially in dry spells, providing about 1 inch of water per week is sufficient. For potted plants or those in well-drained soils, watering twice a week may be necessary. Reduce watering in winter when the plant is dormant. If rainfall is scarce, check the soil moisture level at least once a week and water accordingly, using gallons as a measure for ease.
LightThe Himalayan Fleece Flower thrives in full sunlight to partial shade. The ideal location would be a spot that receives several hours of morning sunlight but is protected from the harsh afternoon sun, particularly in hotter climates. Bright, indirect light will also support its growth, ensuring the foliage maintains its vibrant color.
TemperatureThe Himalayan Fleece Flower can survive a range of temperatures but grows best when the weather is between 50°F and 75°F. These plants are hardy down to about -20°F and can tolerate heat up to around 80°F. Avoid placing it in locations where the temperature can dip below this range for prolonged periods to prevent frost damage.
PruningPrune the Himalayan Fleece Flower to remove spent flowers and encourage a second bloom. Lightly trim the plant in the spring to shape it and remove any dead or damaged growth. Annual pruning is usually sufficient, and the best time for a more thorough trim is after the flowering period has ended.
CleaningAs needed
SoilHimalayan Fleeceflower thrives in moist, well-drained soil rich in organic matter; a mix of two parts garden soil, one part compost, and one part sand or perlite works well. The ideal soil pH for this plant is between 6.0 and 7.0.
RepottingHimalayan Fleeceflower does not typically require frequent repotting; it can be done every 2-3 years if the plant has outgrown its container or the soil appears spent.

Life cycleThe life of the plant Persicaria affinis 'Darjeeling Red', commonly known as Himalayan Bistort or East Indian Knotweed, begins as a seed that germinates in moist soil conditions in the spring. The seedling emerges and develops into a vegetative plant, producing a dense mat of foliage with spoon-shaped leaves. Through the summer, the plant enters its flowering stage, displaying spikes of closely packed, small pink flowers that gradually darken to red. After pollination, typically by insects, the flowers produce seeds which eventually fall to the ground or are dispersed by wind and animals, allowing the plant to spread and colonize new areas. In the fall, the foliage often turns to a bronze color, adding seasonal interest to the garden. Himalayan Bistort then enters a period of dormancy during the winter, with its roots surviving underground to regrow in the next spring, continuing its perennial life cycle.

Spring-summer
Persicaria affinis 'Darjeeling Red', commonly known as Himalayan Bistort or Fleeceflower, is typically propagated through division. The best time to propagate through division is in the spring or early autumn. To do so, gently lift the plant from the soil with a garden fork, being careful not to damage the roots. Once the plant is out, use your hands or a sharp knife to divide the clump into smaller sections, ensuring each section has a good root system and several shoots. Replant the smaller sections immediately at the same soil level they were previously, spacing them about 12 inches (approximately 30 centimeters) apart to allow for growth. Water the new plantings thoroughly to help establish them. This method of propagation is quick and reliable, making it popular among gardeners for expanding their display of the striking, carpet-forming perennial.
