stonecrop

Stonecrop (Hylotelephium telephium 'Blackjack') should be watered when the top inch or 2 of soil feels dry. You should water this plant about once per week in the summer and about once every 2 weeks in the cooler months. Generally, it is best to give the plant a good soaking rather than just a light sprinkle of water. When watering, make sure to avoid over-saturating the soil, as this can cause root rot. The amount of water required will depend on the temperature, humidity, soil conditions and size of the plant.

Stonecrop (Hylotelephium telephium 'Blackjack') grows in full sun to part shade. A sunny location with 4-6 hours of direct sun (especially during the winter months to help prevent powdery mildew) is ideal for this plant species. Ideally, morning sun with afternoon shade is preferred, as it can tolerate more direct sun in the mornings than in the later part of the day. It can also grow in a shady location, but it won't grow as well. Planting Stonecrop in a sheltered location will help the leaves from becoming scorched in the sun and will also help prevent the spread of powdery mildew.

Prune stonecrop (Hylotelephium telephium 'Blackjack') in early spring, after the threat of frost has passed, to control its size and to encourage new growth. Cut off tall, leggy stems and dying foliage, and generally reduce the size of the plant by 1 third to 1 half. In addition, cut off any dead flowers from the previous year to encourage new blooms. Pruning stonecrop is not absolutely necessary, but it can help control the size and shape of the plant and encourage new growth.
