Spectacular fall color is possible in north Texas

Soapberry
 
North Texas is not known for spectacular fall color, unlike New England and some areas near the Rockies. That’s not because there are no colorful trees here (there are several). It’s because the dominant trees exhibit little or no  spectacular fall color, as you might expect from when almost all of north Texas is in what’s biologically-called a “Post Oak Savannah”
Simply put; the sheer number of Post Oak trees (and its relative Blackjack Oaks), overwhelm the trees here showing nice fall color. Over the centuries this natural disparity has increased. Also, unspectacular trees such as Live Oaks, Ashes and some imported, non-native trees have been widely planted.
I suggest, if you want really dramatic color, you plant a “mass” of the same tree species (a “mass” is at least a dozen, planted in a grove). Not only is it more visually striking; it seems to attract more birds seeking protection within the branches.
·      The Soapberry is my personal favorite. This medium-sized tree with an unfortunate name turns a bright yellow-orange in the fall. {see picture)
 
  •       The Red Oak (also called shumard oak) turns into a reddish “torch”   every fall (most of them, anyway)

·      Bald Cypress, by itself can’t be called a spectacular tree. It’s an excellent background tree, however, since it displays a rust-red color all winter long (see picture below).
·      Sweetgum is a dramatic tree.  The tall tree transforms into a brilliant red {sometimes purple) in the fall.
·      Bigtooth Maple is a small tree that’s hard to find in nurseries, but worth the search. It turns into a striking red each fall.
·      Cedar Elm is a fairly comm90n native tree. Many of them (but not all) turn a yellowish about late October.
·      Sumac is a shrubby plant that’s best used when randomly interspersed among large, trees. It's red.
 
These are all native to Texas, but are usually overwhelmed visually by our unspectacular oaks.  In the ‘silver linings department‘ however, and thanks to rampant land-clearing, we have an opportunity to create a patch of vivid color anywhere we can plant a tree. By far the best time of year to plant them is right now, so the roots can grow all during a Texas winter.

owls - a natural, low cost rat control that won't harm pets or other wildlife


Interesting but useless facts; Owls have twice as many bones in their necks as humans, enabling them to rotate their heads 270 degrees (not completely around as the myth claims). A typical adult Barn Owl (seen here in north Texas) can eat about 1500 rats a year, for only the price of housing. A group of Owls is called a “parliament” of Owls, but most people just call them a “bunch”.

 
binoculars for children:    
When selecting binoculars for children,
there are three key criteria:  1. Choose one where the distance between the eyes (“IDP”) adjusts down to a minimum of 50-55 mm.  2. Avoid a toy/compact model – these almost always have smaller focusing dials, which save weight but are difficult for children to use.  3. Steer clear of extra-high magnification and toward a greater field of view, so a child sees more area and doesn’t just get frustrated.
 
The goal is to compensate for a child's decreased motor control, not just to make things lighter.  “toy” binoculars are quite often cheaply made, poorly constructed and have vastly inferior lenses. These built-in flaws will quickly discourage a child from using them, since he/she can’t see much of what real binoculars disclose.
