Q.Cypress trees
After the winter my tree looks brown in places. The tree has Pom proms and I know I have to prun it to keep it’s shape but I am afraid it is dying! The tree was planted last spring. Can you please help? Thank you!

Winter can be tough on Leland Cypress Trees, especially newly planted trees.
Plant tissue that is damaged by cold injury is also more susceptible to bacteria or fungus.
The winter desiccation also results in the slowing of growth and lessens the trees ability to make defensive chemicals.
Prune out and dead and damaged plant material. Since your tree is new and depending on the extent of the winter damage, you will need to determine if enough tree is left to salvage.
