Scouting for Scale at Snowy Solstice dehaas.2 Wed, 12/20/2017 - 09:06

Scouting for scale in the Winter is great use of your time. 

Scale comes in many shapes, sizes and varieties. Last year we saw Oyster Shell, Calico, Juniper, Greevy, Bamboo, Fletcher, Japanese maple, Pine Needle, Brown, Putnam, Euonymus and Magnolia Scale.

Scale is sometimes hard to see when a plant is in full foliage. But in the winter with no leaves on trees and shrubs, except evergreen, scale are easier to see.

Scouting scale in the winter makes sense because there is less to care for outside in the landscape. The following pictures are Scale images on the...

It's a Girl! (YUCK!) bennett.27 Fri, 11/03/2017 - 15:40

This tree has been around a little while in the Snyder Park Gardens and Arboretum.  In fact, it's one of my favorite trees.  It's such a popular tree in this garden that we even decided to move the location of a sidewalk while developing our master landscape design in order to preserve this tree.  However, now that it has revealed its identity, I am not sure what we will do.

 

Yes, this particular tree is a ginkgo (Ginkgo biloba) and it's a girl.  We had no idea.  For at least the last three years while we have been hanging out at this site, creating a landscape...

Disease, Demystified chatfield.1 Sun, 10/29/2017 - 10:49

What are control strategies for managing oak wilt disease? What do we know about beech leaf disease? Does rose rosette virus affect ‘Knockout’ roses? Which crabapples have good genetic resistance to apple scab disease and how does this compare to 20 years ago? Does apple scab on the fruit matter (as seen on the lead slide for this bygl-alert)?

The Beauty of Bottlebrush Buckeye chatfield.1 Fri, 10/27/2017 - 16:48

My, oh my, buckeyes, oh my, the weekend beckons, but for now, let us praise Aesculus parviflora. “No better plant could be recommended as a lawn shrub”, according to W.J. Bean, as quoted in Michael Dirr’s Manual of Woody Landscape Plants. Bottlebrush buckeye, is my favorite shrub” from an unnamed source in Holden Arboretum’s Plant Profiles, probably Brian Parsons.

 

 

  I concur. Palmately compound leaves with 5-7 leaflets, lovely in spring, summer and fall. Multi-stemmed...

Fall Leaf Drop Reveals Calico Scale boggs.47 Wed, 10/25/2017 - 15:38
Calico Scale spends the summer as crawlers attached to the main veins on the underside of leaves. Detection can be a challenge with crawlers distributed on foliage throughout the canopy. However, as fall approaches, the crawlers move onto stems where they spend the winter. Clusters of crawlers coupled with blackened stems are key diagnostic features for detecting a calico scale infestation.
