PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: The best time to plant Penstemon ‘Dark Towers’ is in early spring, when the soil begins to warm. This gives the roots enough time to establish before the growing season kicks off, resulting in a healthy, strong plant.
• Autumn: Alternatively, you can plant Penstemon in early autumn. This allows the plant to settle in before the colder months and get ready for a robust bloom in the following spring.

Site Selection

• Sunlight: Penstemon ‘Dark Towers’ thrives in full sun to partial shade. Choose a location that receives at least 6 hours of direct sunlight each day for the best growth and abundant flowering.
• Soil: Ensure the soil is well-drained, as Penstemon ‘Dark Towers’ does not tolerate waterlogged conditions. The plant prefers fertile, well-drained soil. To improve drainage and soil fertility, mix in organic matter like compost or well-rotted manure.

Planting Instructions

1. Prepare the Hole: Dig a hole that is twice as wide and as deep as the root ball of Penstemon ‘Dark Towers’. This allows the roots to spread out comfortably and establish properly.
2. Soil Preparation: Enrich the soil by adding compost or organic matter to improve fertility and ensure good drainage. Penstemon ‘Dark Towers’ benefits from nutrient-rich soil, promoting healthy growth and vibrant flowers.
3. Planting: Place the plant in the hole, making sure that the top of the root ball is level with the surrounding soil. Fill the hole with soil, gently firming it to eliminate air pockets.
4. Watering After Planting: Water thoroughly after planting to help settle the soil and establish the roots. Ensure that the area drains well to avoid standing water, which can cause root rot.

Watering Requirements

• Growing Season: Once established, Penstemon is moderately drought-tolerant. Water the plant during dry spells, but allow the soil to dry out slightly between waterings. Avoid overwatering, as this can lead to root rot.
• Dormant Season: In winter, reduce watering significantly. Penstemon needs little moisture during its dormant phase, so only water if the soil becomes excessively dry.

Feeding

• Spring: Apply a balanced fertiliser in early spring to give Penstemon ‘Dark Towers’ a strong start for the growing season. This will support healthy growth and encourage an abundance of flowers.
• Mid-Summer: A light feeding in mid-summer can help keep Penstemon vigorous and encourage continued flowering throughout the season.

Pruning

• Deadheading: Remove spent flowers from your Penstemon regularly to prolong the blooming period and encourage new flowers. This also helps the plant maintain a tidy appearance.
• Autumn Pruning: After the last flowers fade, cut back to ground level. This will prepare the plant for winter dormancy and promote stronger growth in the following season.

Mulching

• Spring: In early spring, apply a layer of mulch around the base of your Penstemon to help retain moisture, suppress weeds, and regulate soil temperature. Use organic mulch like bark chips or compost for best results.
• Winter: During winter, a layer of mulch around the plant helps protect the roots from extreme cold and prevents frost heaving, ensuring the plant survives and thrives into the next growing season.

Supporting the Plant

Penstemon ‘Dark Towers’ generally has a sturdy, upright growth habit. However, in particularly windy areas or if the plant becomes top-heavy, consider staking it to prevent any damage to the stems.
