How Do You Plant and Grow Speedwell?

Planting and growing Speedwell is a rewarding experience, as these hardy perennials are quite forgiving and relatively easy to establish. Providing them with the right sunny spot and well-drained soil will ensure their racing beauty in your garden truly shines.

Site Selection: Sun and Soil are Crucial

• Sunlight: Most Speedwell varieties thrive in full sun, meaning at least 6 hours of direct sunlight per day. This promotes the densest growth and most abundant flowering. Some species and varieties can tolerate light partial shade, but may become a bit leggier and produce fewer blooms.
• Soil: Speedwell requires well-draining soil.
  • Ideal: Average to lean garden soil, sandy loam, or loamy soil with good organic matter.
  • Avoid: Heavy clay soils that remain wet for extended periods, as this can lead to root rot. If you have clay soil, amend it generously with compost, coarse sand, or grit to improve drainage. Raised beds are also an excellent option.
  • pH: Tolerant of a wide range of soil pH, from slightly acidic to neutral (pH 6.0-7.0).

Planting Process (from seeds or nursery plants)

• From Seeds (Less Common for Specific Cultivars):
  1. Timing: Sow seeds indoors 6-8 weeks before the last frost, or directly outdoors in early spring or fall. Some species may benefit from a period of cold stratification (exposure to cold, moist conditions) for better germination.
  2. Sow Lightly: Small seeds should be pressed lightly onto the soil surface, as many need light to germinate.
  3. Germination: Can be slow and sometimes erratic.
• From Nursery Plants (Most Common and Recommended):
  1. Timing: Plant in spring after the last frost or in early fall.
  2. Prepare the Hole: Dig a hole roughly the same depth as the nursery pot and twice as wide.
  3. Remove from Pot: Gently remove the plant from its nursery pot. Tease apart any circling roots if it's root-bound.
  4. Position the Plant: Place the plant in the hole so that the top of the root ball is level with the surrounding soil. Avoid burying the crown too deeply.
  5. Backfill: Backfill the hole with soil, gently firming it around the plant.
  6. Water Thoroughly: Water immediately and deeply after planting to settle the soil around the roots.

Spacing: Allow for Airflow and Spread

• Upright Varieties: Space upright Speedwell plants 12-18 inches (30-45 cm) apart. They will form distinct clumps and appreciate the airflow.
• Creeping Varieties: Space groundcover types 8-12 inches (20-30 cm) apart, as they will spread to form a dense mat.
• Airflow: Adequate spacing is important for all types to ensure good air circulation, which helps prevent powdery mildew and other fungal issues, especially in humid conditions.

Watering: Consistent Moisture During Establishment

• Establishment: For the first growing season, water regularly and deeply to help the plant establish a robust root system. Keep the soil consistently moist (but never soggy).
• Established Plants: Once established, most Speedwell species are quite drought-tolerant. They thrive on average rainfall and generally require minimal supplemental watering. Water during prolonged dry spells.
• Avoid Overwatering: While they like consistent moisture, they dislike being waterlogged. Ensure good drainage.
• Mulch (Optional): A 2-3 inch (5-7.5 cm) layer of organic mulch (like shredded bark or compost) around the base of the plant can help retain soil moisture, suppress weeds, and regulate soil temperature.

How Do You Care for Established Speedwell?

Once established, Speedwell is a remarkably low-maintenance perennial, consistently delivering racing beauty to your garden with minimal ongoing care. Its resilience and long blooming period make it a true garden favorite.

Watering: Allow for Drying

• Drought Tolerance: Established Speedwell is moderately drought-tolerant. It performs best with consistent moisture but can withstand short dry periods. Water during prolonged droughts.
• Avoid Overwatering: The most common cause of problems is overwatering or poorly draining soil, leading to root rot. Always allow the soil to dry out between waterings.
• Mulch: Maintaining a 2-3 inch (5-7.5 cm) layer of organic mulch helps conserve soil moisture and reduces watering frequency.

Fertilizing: It Prefers Lean Conditions

• Lean Feeder: Speedwell prefers average to lean soil and generally does not need heavy fertilization. Too much nitrogen can lead to excessive leafy growth, weak stems that flop, and fewer flowers.
• Compost (Optional): An annual top-dressing of finished compost (1/2 inch or 1.25 cm) in early spring is usually sufficient to provide gentle, slow-release nutrients.
• No Synthetic Fertilizers: For best long-term health and vigor, avoid synthetic chemical fertilizers.

Pruning and Maintenance: Encouraging Rebloom and Tidiness

• Deadheading: To encourage a prolonged bloom period and potentially a sporadic second flush of flowers, deadhead spent flower spikes. Cut them back to a strong leaf or side shoot. This also prevents excessive self-seeding (though some self-seeding can be desirable for naturalizing, especially for V. spicata).
• Post-Bloom Cutback (for Spiking Varieties): After the main flush of bloom is completely finished, you can cut back the entire plant by about one-third to one-half. This helps to rejuvenate the plant, encourage denser basal foliage, and may promote a tidier form.
• Winter Cutback: In late fall or early spring (before new growth emerges), cut back all the dead stems to the ground. This tidies up the plant and makes way for fresh new growth.
• Division (Every Few Years): If your clumps become too dense, show reduced vigor, or start to die out in the center, you can divide Speedwell every 3-4 years in spring or fall. Dig up the clump, divide it into smaller sections with a sharp spade, and replant.

Pest and Disease Management: Generally Trouble-Free

• Resilience: Speedwell is generally quite resistant to most common garden pests and diseases.
• Main Problem: Powdery Mildew: Can sometimes occur in very humid, crowded conditions without good airflow. Ensure proper spacing.
• Root Rot: Almost exclusively due to poor drainage or overwatering.
• Deer and Rabbit Resistance: A significant advantage for many gardeners, as deer and rabbits generally tend to avoid Speedwell.
