Planting Veronica
Veronica is happy in Zones 3 to 8. It likes full sun in well drained soil, but will tolerate some shade but the stems may flop a bit in that environment. Plant divisions in either spring or fall. Transplant garden center potted plants anytime during the growing season. Choose an overcast day or plant in the evening to minimize stress from the sun on the transplant.
Prepare the soil down 8 inches and mix in a little granular, slow-acting fertilizer. Add some organic matter to improve soil drainage if necessary. Dig a planting hole about as deep and slightly wider than the plant rootball when it is removed from the pot. Be sure the top of the rootball is level with the surrounding soil when it is set in the hole. Fill in the hole with soil, firming it gently around plant stems to remove air pockets and water well. Set plants about 18 inches to 2 feet apart to allow for their gradual spread.
Care of Veronica
Veronicas thrive with benign neglect.

Pruning/Grooming Veronica – If you cut off spent spikes, the plant will regenerate more. Young plants may bloom all summer with faithful deadheading. Shear low growing types back to foliage growing on soil after second flush of bloom. The taller types of Veronica can be made more compact by cutting off stems in June about 6 inches. That delays bloom a bit, but plants are neater.
Propagating Veronica - Divide Veronica every 3 or 4 years as plants outgrow their allotted space. This gives you new plants and helps to maintain plant vigor for the ones that are left.
