Windsor, ON. Jul.8th, I have one cedar. This was its first winter. 5 ft. Although it was wrapped in the winter, it suffered some browning. It is recovering with frequent slow watering. I understand to water into fall. My question is about fertilizing: I bought golfgreen 30-10-10 but it is hot, cooling at night over the next couple days. Can I fertilize if I keep watering regularly? soon it will be too late for fertilizing . Aline
The Emerald Cedar is a very popular choice, especially for hedges, so we do get a lot of questions about them. Here is the thoroughly detailed response we gave to another gardener who inquired about browning. It deals with soil, watering, and fertilizer, so this is a great all-round guide to care for your tree. https://www.torontomastergardeners.ca/askagardener/dying-and-browning-emerald-cedars/
As you will see from the answer above, July is not too late for fertilizer, and deep watering is more beneficial than frequent watering.
Good luck with your new tree!
