Spring weather 2017: So far it’s Rinse and Repeat

As we spring toward the end of the calendar winter here in the Great Northwest, We at Wolbert’s Plant Essentials look at the weather forecasts and wring our hands a bit.

 The need for dry weather:

With no immediate end to this latest wet weather pattern, it becomes increasingly difficult to plan our treatments to your landscapes that require dry weather to be most effective. Along with the challenge of maximizing what dry weather does present itself, there are the destructive organisms that come to life as a result of extended rainfall, in the form of damaging fungus pathogens. Left untreated, they will take their toll on your roses, fruit trees and susceptible flowering trees.

We have been somewhat spoiled by mostly dry growing seasons the last two or three years, with minimal fungus pressure for the most part. 2017 could be quite different. Although the cooler weather is stalling bud-break on most early blooming plants as of this writing, eventually the warming sun and length of days will win out. Higher temps and humidity will bring to life these rain-spread fungal spores.

Timely treatments:

Our goal is to preempt these damaging fungus infections with well-timed fungicide applications. One of our challenges in that regard, is to track the different varieties  of trees and shrubs that bloom at different intervals in the spring. The timing of our first treatments in the spring depend on what’s in your landscape and which trees you care about the most. Some of the first to bloom/leaf are flowering plum, ornamental pear, willow and  certain varieties of ornamental cherry. Pome fruits are among the last to push leaves in spring and we have many clients who don’t receive their first apple scab fungus treatment until mid April.

If you you have questions or concerns about anything to do with your landscape, we’d be happy to come by and do a walk through to determine where our services would benefit you.
