Planting and Care

Planting

• When to plant: Transplant Veronica during cooler months in spring or fall to avoid heat stress.
• Where to plant: Choose a sunny site with rich, well-draining soil. Veronica can tolerate some shade but may produce fewer flowers. Veronica prefers well-drained, loamy soil with plenty of organic matter.
• How to plant: Loosen the soil and mix in compost. Dig a hole twice the diameter of the container and place the plant in the hole so that the top of the root ball is level with the soil surface. Press down on the soil to remove air pockets and water well.

Care

• Watering: Water young plants regularly until well-established. Once established, Veronica is drought-tolerant and needs little supplemental watering.
• Fertilizing: Veronica is not a heavy feeder and does not require regular fertilization when planted in fertile soil.
• Pruning: Deadhead spent blossoms to encourage rebloom. Cut back taller varieties after flowering to maintain their shape and prevent flopping.
• Dividing: Divide Veronica every few years to reinvigorate the clump and produce more plants.

Veronica does best in areas with moderate humidity and is cold-hardy in USDA Zones 3–11. Once established, Veronica is a relatively carefree plant that requires minimal attention.

Other Insights for Gardeners

• Pest and disease control: Veronica plants attract aphids and whiteflies. These can be controlled with a blast of water from a garden hose, insecticidal soap, or neem oil. Veronica is also susceptible to foliar diseases such as powdery mildew and leaf spot, which are best prevented by allowing for good air circulation.
• Winter care: In areas with harsh winters, cut the plants back to 2 inches above the ground and add a covering of mulch to provide protection.
• Propagation: Veronica can be propagated by division or seed. Division is the most common and easiest method.
• Potential invasiveness: Some species of speedwell, such as Persian speedwell (V. persica), creeping speedwell (V. filiformis), corn speedwell (V. arvensis), germander speedwell (V. chamaedrys), and ivy-leaved speedwell (V. hederifolia), are considered weeds in lawns. It is important to choose varieties that are appropriate for your region and garden conditions to avoid unwanted spreading.
