Astilbe (False Goat's Beard)

• Light Requirements: Astilbe thrives in partial to full shade. While it can tolerate some sunlight, especially in cooler climates, too much direct sun can scorch the leaves and reduce flowering.
• Soil: Prefers rich, well-drained soil with a slightly acidic to neutral pH. Incorporate organic matter like compost to improve soil fertility and drainage.
• Timing: Plant Astilbe in the spring or fall.
• Spacing: Space False Spiraea plants about 12-18 inches apart to allow for adequate air circulation and room for growth.
• Depth: Plant the crown (where the stem meets the roots) at soil level. Water thoroughly after planting.
• Watering: Astilbe requires consistently moist soil, especially during the growing season. Water regularly, ensuring the soil never dries out completely. Mulching around the plants can help retain soil moisture.
• Fertilizer: Fertilize in early spring with a balanced, slow-release fertilizer. Supplement with compost or organic matter annually to maintain soil health and fertility.
• Deadheading: Remove spent flowers to encourage new blooms and maintain plant tidiness.
• Dividing: Divide plants every 3-4 years in early spring or late fall to prevent overcrowding and rejuvenate growth. Dig up the clump, separate the roots, and replant the divisions.
• Pests/Diseases: Astilbe is relatively pest-free but can be susceptible to powdery mildew and root rot if not properly cared for. Ensure good air circulation and avoid waterlogged soil to prevent these issues.
• Winter Care: After the first frost, cut back the foliage to about 2-3 inches above the ground. Mulch around the base to protect the roots from freezing temperatures.

• Companion Plants: Astilbe pairs well with other shade-loving plants like hostas, ferns, and heucheras.
• Cut Flowers: To enjoy Astilbe blooms indoors, cut the flowers when they are half open. Place in a vase with fresh water, and they can last up to a week.
• Height: Most varieties grow to around 16 inches tall, though some can reach up to 2-3 feet.
• Colors: Astilbe offers a stunning palette of spring blooms ranging from pink to white to red.
• Foliage: The fern-like leaves add texture and depth to garden spaces.
• Bloom Time: Typically, Astilbe blooms in late spring to early summer.
• Wildlife: These plants are deer resistant and attract butterflies, adding life and movement to your garden.
• Uses: Astilbe’s vibrant blooms make excellent cut flowers for arrangements. 

Do astilbes like sun or shade?

Astilbes prefer partial shade to full shade. While they can tolerate some sun, especially in cooler climates, too much direct sunlight can cause their delicate foliage to scorch and their soil to dry out too quickly. Keeping astilbes in a shaded or partially shaded area with moist, well-drained soil will help them flourish.

Does astilbe spread?

Yes, astilbes do spread, but they do so at a moderate pace. They grow from rhizomes, which gradually expand and form larger clumps over time. This makes them excellent for filling in shaded garden areas and creating dense, attractive ground covers.

Will astilbe come back every year?

Yes, astilbes are perennial plants, which means they come back every year. In suitable growing conditions, they will return each spring, producing their beautiful feathery plumes of flowers. After their flowering season, their foliage remains attractive until the first frost. 

Does astilbe bloom all summer?

Astilbes do not bloom all summer; their blooming period typically lasts from late spring to mid-summer, depending on the variety and local climate conditions. Most will flower for about two to three weeks during this time.

Is astilbe toxic to dogs?

No, astilbe is not toxic to dogs. According to the ASPCA, astilbe is considered non-toxic to pets, including dogs. This makes it a safe choice for gardens where pets frequent. However, it’s still a good idea to discourage pets from chewing on or ingesting any plants, as some non-toxic plants can still cause mild digestive upset if consumed in large quantities.
