- Grow in moderately fertile, well-drained soil in full sun.
- Plant in the spring. (Veronica can be sowed by seed in containers in a cold frame in autumn but most people start this perennial as a transplant from the nursery.)
- Loosen the soil and mix in compost. Dig a hole twice the diameter of the plant’s container.
- When placing the plant in the hole, ensure the top of the root ball is level with the soil surface.
- Water thoroughly.
- Water in the summer if rainfall is less than 1 inch per week.
- Stake tall varieties.
- Keep covered with a thin layer of compost, followed by a 2-inch layer of mulch to retain moisture.
- Deadhead to extend bloom time.
- After the first killing frost, cut back stems to an inch or two above the soil line.
- Divide perennials in autumn or spring every few years.
