Our camp site has a beautiful white pine which has sap coming from it. It has leaked on our camper. Wondering if this is a seasonal thing. I haven't put out our awning cause I don't want sap to ruin it. Can you please help? Am I safe now to put out our awning?

I have White Pines around the perimeter of my backyard and would like to add some color/excitement. What type of perennial can I plant under and in front of the pines?
In the shade, ferns, hostas, astilbe, bleeding heart, shade annuals like coleus, impatiens, etc. Check out how heavy the root system is - digging there may be difficult. The pine will take up much of the water so be aware of that challenge in keeping plants moist enough. For sun, your choices are only limited by your tastes. Since you want to be able to see the plants behind this planting, keep in mind that height of plants will be a factor. You may want shorter plants here You may even want to consider a ground cover - visit a good nursery and ask lots of questions specifically about your area.
I have a white pine and a Capitata yew in containers and they need to be transplanted into larger containers. I know I will have to prune their roots. I live in Madison, WI, so when should I do this?
Repotting of trees is really no different than most other container plants in that this is normally done while the plants, or trees, are dormant. This makes it less tramatic for the plant. This is normally done in late winter/early spring.
Can I plant 2' or smaller Weeping cedar, White pine, Alaskan cedar, Spruce picea and Weeping Sequoia pendula in containers temporarily until they get hardy and ready for the ground in Utah, and what type of soil or soilless mix do I use?
Yes, you can. This article will help you with the soil mix: https://www.gardeningknowhow.com/special/containers/proper-soil-mix-for-evergreen-container-plants-and-trees.htm You may also want to consider heeling in the trees.

I would like to see a picture of a white pine, pine seed. Is it black? Thank you Sarah

We recently moved to a new house. On the property is a large white pine tree that has an old wound, like a lightning strike. The wound is healing, leaving the wood exposed to the elements and a small area of wood rot is evident. Can the rot be stopped and the wound repaired to save the tree?
In this case I would most certainly call in an arborist to correctly determine if the tree is compromised enough to need to be removed.
Many tree wounds can heal and the tree live without issue.
Grasses under white pines, slower growth...do I need to add something to the soil?
