Can I help my pine trees?
I have 3 pine trees on my lot in a Chicago suburb. They've never really looked good in the 5 years that I've lived here. I've attached a URL for a pic of the worst one in front of the house. I imagine these trees are about the age of the house - 41 years old.
Each year I trim off some of the lower branches because the branches droop practically to the ground. I assume this is normal; from the looks of the trunk, that's been going on since long before I bought the house. I have a few questions...
1. Any idea exactly what type of pine tree this is?
2. Is this "drooping" look normal or unhealthy?
3. How long will pine trees live?
4. Is there anything I can do to help these trees?
I've never fertilized any of the trees around my house; I think I'll start this year.
