Evergreen and other needle trees in the Denver area may have begun to brown and drop their needles. Often times, this worries homeowners that the health of their trees might be taking a turn, but at this time of year, it is typically not the case. It all depends on the behavior of browning and falling needles that your tree exhibits to deduce whether your tree actually has a disease such as casting disease. Check with your local Denver tree care specialists if you are concerned about the health of your trees. Look for the following signs and signals to be sure your Evergreens or other needle trees are in good condition and following nature’s patterns:
- Heavy or Excessive Needle Drop: if your Evergreens seem to be shedding their needles excessively or at more rapid rate, no not be alarmed. Trees dropping their needles in large amounts is often due to over watering or overly dry soil. Dry spells in rainfall can result in this scenario, as your conifer trees still require adequate moisture in order to thrive and support their needle growth. Oxygen is also very important to be aware of near the roots of your tree and overwatering can produce the same effect as under-watering.
- Browning from the Interior: While it might seem worrisome as it happens, it is completely natural for your tree’s needles to begin browning at the interior part of the tree and continue outward. The outer needles remaining green is part of the cycle of the fall, and what most people do not realize is that conifers will at times lose their needles toward the end of summer and early fall months.
- Yellowing of Branches: If your tree exhibits the yellowing of the ends or tips of the braches it is a sign your conifer requires some attention. There is potential that the roots have been damaged or the soil is overly compacted, disallowing proper oxygen or water to seep into the roots. Consider these factors and take action as necessary.
Although it is normal for browning and needle dropping for most conifers, some species actually lose all of their needles each fall to grow back anew in the next spring season. Redwoods, baldcypress, and other deciduous conifers exhibit a loss of all needles.
