    Care Information
    Prefers enriched, moist, well-drained soils but tolerates a wide range. Water deeply, regularly during first growing season to establish an extensive root system. Apply a balanced fertilizer during growing season. To encourage bright red stems, annually prune a third of oldest stems to six inches, leaving strong young whips.Pruning time: late winter to early spring.
    Light Needs:
    <strong>Partial Sun / Partial Shade</strong>: These two terms are often used interchangeably to mean 3-6 (or 4-6) hours of sunlight each day. However, there is a difference.
<strong>Partial shade</strong> typically means the plants will appreciate a more gentle exposure such as the weaker morning or early afternoon sun, with the emphasis on providing the minimum needed shade and sheltering from intense late afternoon sun. <strong>Partial sun</strong> typically means the plants <u>need</u> some direct sun, so the emphasis is on meeting the required minimum hours of sunlight, with filtered sunlight or shade the balance of the day.
Both are best with shelter from the harshest late afternoon sun. This shade could be provided by a structure, a wall, larger plants or  tree(s).
