The Q&A Archives: Loss Of Two Siberian Cypress

Question: Two out of three Siberian Cypresses died over the winter. Is there something special that I should be doing to keep them alive?

Also, I am trying to replace the two and I cannot find a nursery that carries Siberian Cypress in this area. I have tried many of the one's listed on your pages? Any suggestions?

Answer: I'm sorry to hear that your shrubs didn't make it. This "evergreen" s very hardy once are established. It does turn brownish in the winter and may look dead, but will sprout green again in spring. If your Siberian cypress (Microbiota decussata) has indeed died, here are some potential causes. If you planted them last fall, it may not have had time to become well established going into the winter weather, and that may have been its downfall. Other common winter maladies are salt damage, windburn, and frost heaving. Windburn occurs when plants don't have adequate moisture heading into the winter. When the ground freezes and the wind blows, the branches dry out and die for lack of moisture. Water shrubs up until the ground freezes. Then treat with an antidesiccant spray to prevent windburn. Frost heaving occurs when the ground alternately freezes and thaws, heaving the plants around in the soil, and can damaging roots. After the ground freezes, apply a thick layer of mulch to prevent it from thawing until spring.
