I have a few Russian Cypress in my front east-facing yard. I don’t know how old they are but there is a severe browning taking place and so plant seems to be dying, or at least damaged. I live in Hudson Valley, NY. I would like to revive them. Is it worth it? And how do I go about? Prune and fertilizer?
Your shrubs could be declining due to age, winter damage, water issues or disease.
You can prune out the dead plant material and inspect the plants for any other signs of pests or disease.
