watering
When watering Culver's root (Veronicastrum sibiricum), aim to provide at least 1-2 inches of water per week. Remember to water deeply to encourage the roots to grow deeper and become more drought tolerant. Water in the morning so the plant has the entire day to absorb the moisture. As the plant matures, reduce watering to every 7 to 10 days during the summer months. In the winter, reduce watering even further and only water when necessary.
sunlight
Culver's root (Veronicastrum sibiricum) prefers full sunlight and should receive 8-10 hours of direct sunlight every day. It grows best in slightly acidic soil with a pH between 5.5 and 7.0. It should be watered when the soil is dry to the touch, usually about once a week during the growing season. During periods of limited rainfall, it should be watered more often. It should not receive too much water as this may cause the plant to become waterlogged and could result in root rot.
pruning
Culver's root should be lightly pruned in late spring or early summer when new growth appears. The best practice is to remove dead or diseased branches, or those that are crossing or rubbing against other branches. If plants are in need of pruning to thin out, remove no more than 30-50% of the overall branches. Pruning should be kept to a minimum, as it reduces the showy flower clusters the plant produces.
