Over-Exposure to Sun
Frost Damage
- Brown leaves appearing on trees in spring can indicate frost damage. This can ruin the tree's appearance temporarily, but it's unlikely to kill the tree. If browning appears in summer, inadequate watering or high winds may be the cause. Leaves with black spotsare likely caused by a fungus that thrives in moist conditions, making this a common problem in humid climates. Magnolia tre…
Transplant Shock
- Trees that have recently been transplanted often experience a difficult period of transplant shock, leading to a host of potential problems, including leaf wilt, leaf scorch, yellowing leaves, and leaf rolling or curling. Don't assume you need to water a tree more just because it has brown leaves when its foliage would normally be green. Don't worry if your tree is experiencing transplant shoc…
Insects and Disease
- When treating your tree for insects or disease, it's important to confirm exactly what the issue is before taking action. Once you've targeted the condition, most often there is a type of spray that will aid in eradicating the insects or disease. Emerald cedar, or 'Emerald Green' arborvitae, commonly develops brown leaves in summer. This can be due to several factors, including insec…

During the first few months, a daily watering with a hose is necessary for many types of trees if you don't have an irrigation system in place. If your area is experiencing a particularly dry season, more established trees will also require watering to maintain their health…
