verbascum

Verbascum pyramidatum prefers consistently moist soil, so it is important to water regularly throughout the growing season. As a general rule of thumb, provide 1 inch of water once weekly (more frequently during periods of extreme heat or prolonged dry spells). When watering, moisten the soil thoroughly, and then allow the soil to dry out slightly between waterings. Consider using a moisture meter to help you determine when the soil is dry enough to water again. During the colder months, reduce watering to approximately once every 2 weeks. Be careful not to overwater as this can lead to root rot and other issues.

Verbascum pyramidatum needs full sun, 6-7 hours a day for optimal growth. It prefers a south, south-west facing site, as that will get the highest intensity of direct sunlight across the day. It can cope with partial shade if necessary, but it will produce fewer and smaller flowers. If the plant is situated in a partially shaded area, it will still need occasional exposure to full sun for several hours each day.

Verbascum pyramidatum should be pruned back in late winter or early spring, just before the new growth begins. The plant should be cut back by 1/3 to 1/2 of the total height. This will help encourage more compact growth, more flowers, and stronger stems. Deadheading regularly throughout the growing season is also recommended to encourage more flowering and to keep the plant looking neat and tidy.
