My white pine is losing and dropping green needles. It was very late in producing new candles and then they were very small and not growing (one half inch). Others in yard same age with candles 5" long. It appears to be losing more needles at the top of the tree. Is this a disease?
There can be many reasons for needle loss, including natural aging, environmental, disease and pests.
Look for more signs to help narrow and pinpoint the cause.

I would also encourage you to contact your local County Extension Office. They may have more information on if any regional pests and disease concerns.

Small worm type in tree causing limp browning. How do I save my white pines from this grub type larva from killing my 6' newly planted trees?
That sounds like Pine Sawyer beetles. They are very difficult to control once symptoms are obvious. I would contact the nursery you purchased these trees from and explain your problem.
Here is an article about them and a few other borers;

I have three white pines on my property. The tree that is at the top of a backyard hill (granite) has turned yellow almost overnight. It is the only tree doing that. The other two are on lower ground and are still green. I understand they shed somewhat in the fall. The site: https://www.gardeningknowhow.com/search/?q=white%20pine%20needles%20turning%20yellow ...tells me it could be for lack of water and in this area (just north of Kingston ON) it has been dry for about three weeks now after a very wet summer. Thank you.
Yes, I do believe this is the most likely situation. It seemed to be getting enough water until recently. If you can try to get extra water up to the tree.
I have 3 lovely 8 yr old white pines inyard up against lanai, sadly one otheie riots are coming above ground & when I mow grass, roots are getting scraped , the other end seems root may be starting to go under pavers on lanai. I love the pines, nice shade, yet the roots! If I cut ANY part of roots..... will th tree die?? The roots are going in many directions 5-10 feet away from tree. What might you do ? A neighbors said you cut the root Through with chainsaw , pine tree will Get weak & could collapse alone...... in a dilemma Thank you
This is unfortunate, as these roots can get MASSIVE, and cause many problems to any structures nearby, and they will go above ground naturally. I fear that your only solution here is to completely remove the tree. Otherwise, you may be looking at some expensive structural repairs to the house along with cutting the tree out. It is best to plant these well away from dwelling or water lines. I hate to bring this information to you, but this is a difficult situation.
I planted some white pines last spring and a couple are not looking good. I attached pictures. DO you think this is normal, will they survive. Or are they dying
There are several factors that may be affecting your pine. There are several fungal diseases of the needles including white pine blister rust. There is "white pine decline" noticed in many states with no known cause. Then there are environmental stresses. While the tree prefers lots of sun, it doesn't like lots of wind in an exposed site. The roots have difficulty keeping up with moisture loss. Pine also requires an acidic pH and well-draining soil. Trying to grow in clay will not work. Other potential issues include inadequate watering and incorrect planting. If this was a container plant, there could be encircling roots which will eventually kill the tree. You should have 3 inches of mulch over the drip line but not against the trunk. Check the website of your state's county extension service (PickYourOwn.org) for information on pine diseases in your region. Extension offices have diagnostic services, sometimes via online pictures, so look into that. Of course, a professional arborist is your best bet for getting an accurate diagnosis and management plan.
Why did one pine tree die the one next to it is healthy? Both were planted as saplings and are now 15' tall. Suddenly over last winter one died. It's completely brown, yet 10 feet away its twin is healthy growing? I can see no wounds or sap on the bark. No exposure to road salt. 50 feet away are huge healthy pines.
Trees can die off for different reasons, environment, pests and disease.
