||Conifers will naturally shed needles every year on the interior of the tree. It is important to identify needle loss due to the exposure to sun and wind on the exterior of the tree. When trees become excessively dry, they lose their rich green color. Branches and bark shrivel. Needles become brittle and break off easily. Very dry trees may not take up water.||
|String Burn & Sunscald
||String burn occurs when string-baled trees are exposed to direct sunlight. Needles adjacent to the string will become red or brown. It can occur in as little as an hour of severe exposure.
Sunscald is very similar to string burn, but the whole side or top of a tree can turn red or brown.
||A tree trunk may split any time rapid moisture loss occurs. A crack will not affect water uptake.||
|Failure to Take Up Water
||Only very dry trees fail to take up water. Resin can also seal the trunk and limit water uptake.||
