I have noticed tnat my aborvitae have developed brown patches in the last week. Is this seasonal or a sign of a problem?

Good question. I had some after the winter and was told that I need to protect them from the snow and ice.
A spray to seal the moisture in and keep them from drying out.
I'm good and green, however next door they have patches of rust.
Any ideas? |

Mine always go a bit brown and lose some needles in the fall. I think they are simply lightening up in order to spare themselves broken branches during winter snows. They always perk up again in spring.

This is more than I know (off Google), but it is not the solution to the original posted problem:
Antidesiccants
Every fall about this time the subject of whether or not it is safe to spray evergreens with an antidesiccant such as Wiltpruf comes up. Antidesiccants are a great idea for helping evergreens retain moisture during winter, but some of them do pose a slight problem. Not all evergreens go fully dormant on the same schedule; for instance, those in the cedar family such as arborvitae require a lot more consistently cold weather to shut down. On those evergreens, it is best to wait until late November or even early December to spray them with Wiltpruf. That way you'll be sure they are dormant. When sprayed before they are fully dormant, the moisture the plant is still giving off through its foliage can be trapped under antidesiccant coatings and cause damage during freezing weather. We suggest waiting for a sunny day in early winter that stays above freezing for the day. Spray early so the antidesiccant can dry before night. The woody twigs and branches of newly planted deciduous plants can benefit from an antidesiccant in winter, too.

My mom-in-law recommended we use Muracid (by the Miracle Grow people) when they brown and it appears to have worked in the past. Like Miracle Grow, you add it to water and give the ground a good dousing. |
