A Horticulturist's Guide to Growing Speedwell/Veronica Plants

A Hardy Ornamental, Learn How to Grow Veronica Plants

Veronica, commonly known as Speedwell, is a diverse genus that spans from ground covers to tall, spiky flowers, offering a delightful collection of colors and sizes to the garden. Find insights on how to grow veronica without harmful pesticides, ensuring that these charming plants not only thrive in your garden but also contribute to a healthier ecosystem.

Choosing Your Veronica Variety

Veronica species and cultivars range widely, with blooms in shades of blue, white, pink, and purple. When selecting veronica for your garden, consider the plant's mature height, bloom color, and growth habit to suit your garden's design and your personal preferences. Whether you're looking for a ground cover like Veronica repens or a taller, eye-catching variety such as Veronica spicata, there's a veronica to meet most gardener's needs.

Planting Veronica

Location: Veronica thrives in full sun to light shade. Adequate sunlight is crucial for optimal growth and flowering, although some afternoon shade in hotter climates can prevent scorching.

Soil Requirements: Choose a site with well-drained, moderately fertile soil. Good drainage is essential to prevent root rot, a common issue in poorly drained areas. If your soil is heavy clay or overly sandy, amend it with organic matter to improve texture and fertility.

Spacing: Plant veronica 15 to 18 inches apart to ensure adequate air circulation and room for growth. Proper spacing helps reduce the risk of fungal diseases by allowing foliage to dry quickly after rain or watering.

Planting Steps: Dig a hole slightly larger than the root ball, place the plant at the same depth it was in its pot, and fill in with soil, gently firming around the roots. Water thoroughly after planting to settle the soil and hydrate the roots.

Organic Care for Veronica

Watering

While established veronica plants are relatively drought-tolerant, they benefit from regular watering during dry spells, especially during their first growing season. Aim for consistent moisture, but allow the soil to dry slightly between waterings.

Fertilizing

Apply a balanced, organic fertilizer in early spring as new growth appears. Organic fertilizers release nutrients slowly, supporting healthy growth without the risk of overfeeding and burning your plants.

Mulching

A layer of organic mulch around veronica plants can help retain soil moisture, suppress weeds, and gradually improve soil quality as it decomposes. Keep mulch a few inches away from the plant stems to prevent moisture buildup that could cause rot.

Pruning and Maintenance

Deadheading spent flower heads encourages veronica to produce more blooms, extending the flowering period. In early spring or fall, divide plants every 3 to 4 years to rejuvenate them and prevent overcrowding. This is also a great opportunity to propagate new plants for other areas of your garden.

Pest and Disease Management

Veronica is generally low maintenance but can occasionally encounter issues with powdery mildew or spider mites, especially in crowded conditions or poor air circulation. Promote healthy growth and reduce the likelihood of problems by planting in well-drained soil, spacing plants appropriately, and using organic methods to address any issues that arise.

Encouraging Biodiversity with Veronica

Growing veronica organically not only enhances the beauty of your garden but also supports local wildlife. Veronica varieties are known for attracting bees, butterflies, and other pollinators, playing a crucial role in the biodiversity of your garden ecosystem.

Of course, true xeriscaping requires a great deal more than just putting in some drought tolerant plants.  The most advanced xeriscaping efforts require rethinking the entire landscaping from the bottom up, using specialty grasses, carefully built gradients to channel water in the appropriate ways, and careful balancing of shade and sun.  You don’t, however, need to be an advanced xeriscape gardener to get real water-saving benefits from your garden this year.
