WaterFalse Spirea requires consistent moisture and should be watered about once a week, with more frequent watering during hot, dry periods. A thorough soaking is preferred, so aim to provide about one gallon of water per square foot of soil during each watering session. The soil should be kept moist, but not waterlogged, as this plant does not tolerate drought well. Adjust your watering schedule based on rainfall and check the top inch of soil for dryness before watering again.
LightFalse Spirea thrives in partial shade, and the ideal spot for it would be an area that receives morning sun and afternoon shade. This plant can also grow in full shade, though flowering may be less prolific. Avoid placing the False Spirea in full sun, as this can lead to scorching of the leaves and stress to the plant.
TemperatureThe ideal temperature range for False Spirea is between 60°F and 75°F, making it suitable for many temperate climates. It can survive winter temperatures down to -20°F, but may not tolerate high heat above 85°F very well. It is important to provide adequate mulching to protect the roots from extreme temperatures.
PruningPrune False Spirea to remove spent flowers and encourage new growth. This is best done immediately after blooming to get the plant ready for the next season. Pruning can be done annually, and you can also cut back the plant in late winter or early spring to maintain its shape and promote more robust blooms.
CleaningAs needed
SoilFalse Spirea thrives in moist, well-draining soil rich in organic matter with a pH range of 6.0 to 8.0. A mixture of garden soil, peat moss, and perlite is ideal for ensuring adequate moisture retention and drainage.
RepottingFalse Spirea doesn't frequently require repotting, as it can often be divided in the garden. However, potted specimens should be repotted every 2-3 years to refresh the soil and accommodate root growth.
Humidity & MistingFalse Spirea prefers high humidity levels, which mimic its natural forest floor habitat, but it is quite adaptable and can tolerate moderate humidity levels common in many homes.
Suitable locationsIndoor
Keep in indirect light, maintain moist soil, ensure high humidity.
Outdoor
Plant in partial shade, keep soil consistently moist.

Life cycleThe Astilbe 'Hyazinth', commonly referred to as False Goat's Beard, begins its life cycle as a dormant rhizome or as seeds that germinate in spring. Once the temperatures warm, the fern-like foliage emerges from the rhizomes, followed by plume-like flowers that can bloom from late spring to midsummer. After flowering, the plant sets seed, which may be dispersed by wind or wildlife, potentially giving rise to new plants. Throughout the growing season, Astilbe expands by sending out new shoots from its rhizomes. As temperatures drop in the fall, the plant's above-ground foliage dies back; however, the rhizomes remain alive underground, surviving through winter dormancy. With the return of favorable conditions the following spring, the cycle starts anew with the emergence of fresh growth.
PropogationPropogation time
Spring-Early Summer
The most popular method for propagating Astilbe 'Hyazinth' (× arendsii), commonly known as False Spirea, is by division. This should ideally be done in the spring as new growth begins or in the fall after the flowering has finished. To propagate by division, carefully dig up the entire clump of the plant ensuring that you get a good amount of the root system. Gently separate the clump into smaller sections, each with at least one bud or eye attached to a piece of the root. Replant these divisions immediately into prepared soil, ensuring they are spaced about 18 inches (approximately 45 centimeters) apart to allow for growth. Water the new plants thoroughly to help establish them. Division not only helps to propagate new plants but also rejuvenates older clumps that may have become woody and less floriferous.
