This year no new pine cones!
The culprit is probably some type of disease or insect. So, if one-third to one-fourth of the needles on the inner parts of your evergreen tree are falling off, it is probably just a normal sign of aging. Just rake up the dead needles, or better yet, leave them under the tree for a good mulch. Aug 27, Assuming the pine tree doesn’t get an adequate amount of water, the brown needles will die and fall off.
Fungal Disease Can Also Cause Pine Trees to Shed Their Needles. A fungal infection can cause pine trees to shed their needles as well. Dothistroma, for example, is a fungus responsible for needle blight. When the needle blight-causing fungus infects a pine tree, the needles will die and fall Reviews: 2.

Firs and spruce trees lose a small percentage of needles year-round. Removing trees osrs 08, Fall needle drop is probably most noticeable in Eastern white pine.
Since these trees only hold their needles for years, there is less new growth at the tips to cover up the older, yellowing foliage.
Additionally, these trees have a relatively open structure, making it easy to see fall needle drop.

Dec 07, If your pine tree has browning or falling needles, you first need to identify the cause in order to help treat the issue. In an indoor pine tree, brown needles are typically a result of a lack of humidity or too low of a temperature. For an outdoor pine tree, browning needles are usually a sign of either waterlogged roots or a drought. Aug 09, If new needles located on the tips of the lower branches are stunted or turning brown, they may be affected by a fungus known as diplodia or tip blight, which you can treat with a fungicide.
A pine tree developing brown needles in the fall may be caused by pine wilt disease, which usually kills affected trees within a few months.
