With its soft, feathery foliage and colorful flowers it’s easy to see why this plant is a favorite for many gardeners. When adding Aaron’s beard to your garden or landscape, proper planting depth is key to getting your plants off to a good start. In this article we’ll look at how deep Aaron’s beard needs to be planted for optimal growth and performance.

About Aaron’s Beard

Also known by its botanical name Hypericum calycinum, Aaron’s beard is a semi-evergreen perennial plant. It’s native to southeastern Europe and Asia Minor. The name “Aaron’s beard” comes from the fluffy stamens on the flowers that resemble a beard.

This tough plant thrives in zones 5-9 and can tolerate most soil types. It grows rapidly, spreading 12-24 inches wide and reaching 12-18 inches tall The foliage is blue-green in color and the stems are woody

From late spring to midsummer, Aaron’s beard produces abundant bright yellow flowers with prominent stamens up to 2 inches across. These cheery blooms attract pollinators like bees and butterflies. After the flowers fade, ornamental seed pods develop that persist through winter.

Planting Depth Guidelines

When planting Aaron’s beard follow these tips for optimal planting depth

• Aim for a depth of 1-2 inches. This shallow planting depth is ideal for Aaron’s beard. Planting too deep can cause poor growth and reduce flowering.

• Check the root ball depth. Remove the plant from its container and inspect the root ball. Plant it so the top of the root ball sits 1-2 inches below the soil surface.

• Plant at the same depth as grown. If you’re transplanting Aaron’s beard from another spot, plant it at the same depth it was originally grown at.

• Avoid planting too deep. Never plant Aaron’s beard deeper than 2 inches. Deeper planting can smother the roots and crown leading to decline.

• Water well after planting. Be sure to water thoroughly after planting to settle the soil and eliminate air pockets around the roots.

• Add mulch. Spread a 2-3 inch layer of shredded bark, leaves, or other organic mulch around plants to conserve moisture and suppress weeds. Leave a gap near the crown.

Preparing the Planting Site

When preparing a site for Aaron’s beard, make sure it has these characteristics:

• Full to part sun exposure – Aaron’s beard thrives in full sun but also grows well in part shade. Provide at least 4-6 hours of direct sun daily.

• Well-draining soil – Although tolerant of many soils, Aaron’s beard prefers consistently moist but well-draining soil. Amend clay soils with compost to improve drainage.

• Neutral pH range – Test soil pH and amend as needed to reach a target pH of 6.5-7.0. Aaron’s beard grows best in neutral to slightly alkaline conditions.

• Shelter from wind – Protect plants from strong winds which can damage stems and foliage, especially when young. Site them near other plants, a fence, or wall.

Taking time to prepare the planting site by adjusting soil structure, drainage, pH and exposure will get your Aaron’s beard off to the best start.

Planting in Containers

Aaron’s beard also grows well in containers, making it perfect for front porches, patios, and other garden beds. Follow these tips when planting it in pots:

• Choose a large container. Select a container at least 12-16 inches wide and 10-12 inches deep. This gives roots ample room.

• Use a quality potting mix. Potting mixes that contain compost or other organic matter are ideal. They hold moisture but drain well.

• Plant at the same depth. Position the top of the root ball about 1-2 inches below the pot’s rim.

• Water until it drains. Water thoroughly after planting until water drains from the pot’s bottom.

• Fertilize regularly. Feed container plants monthly with a water-soluble fertilizer during the growing season.

With proper planting depth and care, container-grown Aaron’s beard will thrive and brighten any outdoor space.

Caring for Aaron’s Beard Post-Planting

Once planted, Aaron’s beard requires minimal care to look its best:

• Water 1-2 times per week. Provide at least 1-2 deep waterings per week to maintain moist (but not saturated) soil. More frequent watering may be needed in hot, dry weather.

• Apply fertilizer once or twice yearly. In spring and/or early summer, feed plants with a balanced flower fertilizer following label directions. Avoid high-nitrogen formulas.

• Prune lightly after flowering. To promote dense growth, prune off spent flower stems after blooming ends. Remove up to one-third of the plant’s height.

• Watch for pests and diseases. Aaron’s beard is relatively trouble-free but can be affected by leaf spot, rust, root rot, and Japanese beetles. Address issues promptly.

• Cut plants back in winter. In cold zones, cut Aaron’s beard back to 6 inches above the ground in late fall to prevent winter dieback.

Troubleshooting Problems

If your newly planted Aaron’s beard fails to thrive, look for these common issues:

• Planted too deep – Replant at proper 1-2 inch depth.

• Overwatering – Allow soil to dry between waterings and ensure potted plants have drainage holes.

• Underwatering – Increase watering frequency and deeply soak the root zone.

• Insufficient sunlight – Move plants or prune back encroaching trees and shrubs to boost light levels.

• Poor drainage – Replant in well-draining soil or use raised beds to improve drainage.

• Root damage – Avoid disturbing the roots when transplanting and planting.

• Incorrect pH – Test and amend soil pH if needed to reach neutral range.

With the proper planting depth and care, Aaron’s beard will quickly establish and reward you with its handsome foliage and abundant blooms for years to come. Pay close attention in the first year and you’ll reap the benefits for seasons to follow.

Frequently Asked Questions

How much sun does Aaron’s beard need?

What type of soil is best for Aaron’s beard?

These plants are adaptable to most well-draining soils but prefer consistently moist, humus-rich soil. Amend clay soils with compost to improve drainage and water retention.

When is the best time to plant Aaron’s beard?

Spring and fall are ideal planting times to give roots time to establish before summer heat or winter cold. Avoid planting in mid-summer heat. Container-grown plants can be planted anytime.

How far apart should I space Aaron’s beard plants?

Space Aaron’s beard plants 12-18 inches apart. They will rapidly spread to fill in. For a dense hedge, set plants 8-12 inches apart.

Should I fertilize Aaron’s beard after planting?

Hold off on fertilizer for 2-3 months after planting to allow roots to establish. Then apply a balanced flower fertilizer once or twice per year according to label directions.

How can I get Aaron’s beard to flower more?

To maximize flowering, provide full sun, prune spent blooms promptly after flowering, and avoid overfertilizing with nitrogen. If bloom production declines, plants can be divided every 2-3 years.
