tanacetum

Water thoroughly weekly when Tanacetum plants are actively growing. Allow the soil to dry out slightly between waterings, but never allow it to become bone dry. Once flowering has finished in late summer, reduce watering to every other week. Do not water Tanacetum plants in the winter—they are dormant at this time and too much moisture can cause root rot.

Tanacetum haradjanii, or Caucasian tansy, is a flowering plant species native to the Caucasus Mountains in Georgia. This species prefers full sun and flourished in sunny conditions. During the spring and summer months, ensure that Tanacetum haradjanii gets 8-12 hours of direct sunlight per day. In the fall and winter, ensure it gets at least 6 hours of direct sunlight per day. Additionally, avoid shady locations with dappled sunlight or intermittent shade, which can inhibit the plant’s growth.

Tanacetum (Tanacetum haradjanii) should be pruned every spring or early summer, when new growth begins. Pruning should calm the large plant down and keep it from spreading. Trim off any dead flowers and remove any unneeded branches. This will encourage the plant to develop a dense shape and keep it looking full. To encourage flowering, pinch off the tips of the branches in late summer once bloom begins to fade. Prune only a small amount of the plant each year so as to not overwhelm or damage it.
