Arborvitae
Arborvitae trees are classic favorites for easy-care evergreens that act as hedge or privacy screens. Their sturdiness can withstand heavy snow and also provide a natural windbreak. Arborvitae trees are native to eastern America and are also known as northern white cedars.
Dieback/Flagging
Arborvitae dieback/flagging is often caused by:
- Borer (Multiple)
- Phytophthora Rot
Sawdust/Holes
Small holes in the bark and sawdust coming from said holes are typically the result of wood-boring pests. Bark beetles often leave sawdust in or near the holes the insects have burrowed into/out of and seek out weak trees that are stressed by environmental stress, improper watering, pruning injuries, or other insect attacks.
Yellowing/Browning
Arborvitae yellowing/browning is often caused by:
- Bagworm
- Phytophthora Rot
