A pileated woodpecker has created a hugh hole in what appears to be a healthy, very large pine tree. How can I fill it/fix it to prevent further damage to the tree?
If it is just a few holes, treat them with an insecticide and a fungicide (neem oil is nice because it is both) and let them heal over naturally. If it is more than a few holes or they are big holes (more than 1 inch), you can cover the area with hardware mesh to keep animals out.
Why is the pine tree in my back yard dying, or is it? It is about 50 feet tall and the bottom 1/3 is brown. Should I trim the brown branches?
Do you know the variety of the pine tree? Knowing this will help us better identify what is wrong with it for you.
I am moving into an apartment that has two mature trees, but they really need to be cut back, as they obstruct views of the tenants above, and also one is pushing against some windows. I don't know what they are. One is a type of pine, the other has a red-colored leaf. Any advice?
Unless you bought the apartment house, they're not your trees. Talk to your landlord.
If they're your trees, talk to a tree service with an arborist. Once pruned, pines won't produce new growth. Deciduous trees can be pruned back from windows and walls.
We have a large pine tree that had an ant nest in it. They were burrowing a hole for the nest. We killed the nest. Should the hole be filled? If so, with what?
Most arborists today reccommend allowing the tree to heal itself. Keep an eye on it to make sure the ants don't return.
I have recently lost a pine tree and wondered if the needles would make a decent mulch or go into the leaf mould.
I frequently use pine needles in my beds. It actually takes some time before they break down enough to make the soil too acidic for plants to stand. You can also add them to the compost pile.
We use pine needles as mulch in our Rose garden. It raises the acid level which roses like. It and daily light watering will make roses bloom like crazy.
Can small (2-3 ft. high) pine trees be grown in containers?
Yes, they can be grown in containers. You just need to be sure it is a big enough container for proper growth on the root system. Here is also some information on the soil needs: https://www.gardeningknowhow.com/special/containers/proper-soil-mix-for-evergreen-container-plants-and-trees.htm
I have pine trees in my yard. What can I do to make and produce a better garden? How can I treat the soil for better growth of my vegetables and flowers? And my tomatoes are getting splits in them, like a bug is eating them. What do I do for that?
Over time, pine needles can acidify soil, so I would get your soil tested and correct any pH problems. This will give you a good start to growing in the soil. You may also want to look for plants that like acidic soil. This article has some suggestions:
