Our Russian sage (Perovskia) is full and bountiful but will not stay upright. Is there anything we can do? Is there a way to split some off when it has outgrown its space? Should it be trimmed back in fall or spring?
The normal growing habit of Russian sage is to open in the center, according to Tina Pansic, staff horticulturist at Chalet Nursery, Wilmette, who says this is a common complaint. Russian sage must be grown in full sun and can be supported by pea stakes (willow or dogwood branches) or commercial wire stakes. A new cultivar, ‘Little Spire’ is shorter and will stay upright. Your plant can be divided by breaking up the root system with a spade as the bottom stems get woody.Wait until spring to cut the plant to the ground. Plants that are cut back in autumn suffer more winterkill. Pansic cuts her perovskia halfway down in late summer to control the spreading, and then cuts it to the ground the following spring
I have a cycas palm and am not sure how much direct sunlight or water it needs. It has light brown marks developing on the leaves. What is causing this, and how do I care for my plant?
I plan on saving my amaryllis bulbs that I kept outside over summer, but I noticed red streaks on the inner side of the leaves. What caused that? Will I be able to save my bulbs?
I have read that purple coneflowers (Echinacea) are a good source of food for birds in the winter. Will they be okay if not trimmed back until spring? If so, how early should they be trimmed?
