I would simply like some advice on the matter of Pruf Wilt. I just planted two rhododendrons in an area that is windy during the winter months.
. Just how effective is this product and when would be the best time to apply the Pruf Wilt?

In regions where the soil freezes, fall is generally not the best time to plant evergreens. While roots scramble to establish before winter, there isn't enough time for foliage to adapt to a different, harsher climate.

enter Wilt Pruf. A good idea for this first winter to help prevent desiccation. Do read the directions. As I recall, it needs to be above 40°F at application and until it dries. If the directions say to do the undersides of the leaves, than do it. Otherwise, apply and whatever gets wet is fine. I believe a second applications is recommended in late winter, if and when temps are above 40.

Thank you kindly for your prompt reply. Hopefully, they should be well established and planted over a month ago. I'll further check on the instructions for the application once I see which brand is the best route to go.

You might consider wrapping the plants with burlap to limit sun exposure and mitigate the desiccating effects of wind.
