Leaf Scorch

Brown leaves on trees and shrubs can be indicators of leaf scorch.  Leaf scorch occurs during hot weather when the rate of water uptake by roots is exceeded by the rate of water loss from leaves.    Plants respond to rapid water loss by willingly letting some leaves die back so that water intake equals the…

Pruning Yews – Shearing or Thinning?

Ok, so it’s time to prune yews…how do you know?  Just look at the shrub/hedge.  At this time of year, you’ll see lots of lighter color shoots at the ends of the stems.  If you want to keep the size the same, (and most of us do), now is the time.  So, how to do…

Japanese Beetles—They’re Colorful, They’re Hungry and They’re Here

The most important thing to understand about Japanese beetles is their feeding doesn’t kill trees, shrubs and flowers.  Granted, it isn’t fun to see the lacy leaves they’ve created, but pesticide management options require thought and planning before you set out for revenge. Systemic insecticides, for instance those containing the active ingredient imidacloprid, are taken…

Leaf Scorch

Leaf scorch, also called sunscald, is the bronzing of leaf surfaces and crisping of leaf edges.  Even plants that are well-adapted to our climate can be scorched.  Plants have amazing resiliency, especially when Mother Nature eases them into changing seasons.  But taking into consideration a spring like this one—cold and rainy—then an abrupt change to…

Early Summer Stress

What happened to spring?  We know that Southeast Nebraska and Southwest Iowa can have some challenging weather to contend with, but this caught us all off guard.  We are getting calls asking how this will affect our landscape plants and what can be done to mitigate damage.  We experienced record heat over Memorial Day that…

Maple Bladder Galls—“Freckles” on the Leaves

If you have a sliver or red maple tree, you’ve most likely noticed small raised bumps on the leaves.  Tree owners will call them “freckles”, “measles” and sometimes even “zits”.  Whatever they are called, maple bladder galls are caused by a very tiny mite.  The galls themselves are made up of plant tissue and are…

Mulch Volcanoes—Compromising Tree Health

You’ve seen this before—mulch piled so high around a tree that it resembles a volcano with a stick coming out of the center.  So goes the plight of trees trying to survive under such conditions.  Despite the research indicating how bad this is for trees, we see it time and again. Exactly how do mulch…

Right Plant, Right Place Part 2

  The coined phrase Right Plant, Right Place (RPRP) has stuck for many reasons, but the most important one is that it has passed the test of time.  Also, it’s just common sense.  Basically, RPRP is relatively straightforward; it’s about installing the best plant for the site, taking sun/shade, soil characteristics, pest history and many,…
