- The first picture is the end result of ponderosa pines about 40 years old that succumbed to girdling roots left around the base of the tree. This tree was buried slightly deeper than it should have been. A strong wind of 50 miles an hour pushed this tree over.
- In the second picture it shows the root ball in the planting hole with burlap and twine still enclosed in the wire basket. Both the burlap and wire basket need to have the top third removed to allow the roots to spread. Roots generally go out and slightly up toward ground level. In some cases, Maples and Colorado Blue Spruce are shallow rooted trees.
- What causes burlap not to decompose quickly? Burlap does not decompose quickly here in many locations on the eastern plains of Colorado because of improper water levels in the soil, too high or too low pH, lack of proper oxygen, lack of available nitrogen, higher levels of aluminum or manganese. In turn the microbes, particularly bacteria are responsible for decomposition is lessened due to the stress placed on them by the poor environment of our soils.
- There are other living organisms in our soils besides bacteria in the following descending order:
- another group of bacteria called actinomycetes providing valuable antibiotics,
- fungi provide soil stability with their threadlike filament structures,
- algae and cyanobacteria are photosynthetic microbes which can add small amounts of carbon to soil and
- protozoa which make nutrients available by mineralizing them for plants and animals.
- Other than those mentioned above, there are more soil animals such as nematodes, microarthropods such as mites and springtails and larger animals such as earthworms and burrowing insects like dung beetles.

In times of great human need we rescue each other and at other times we may be called to rescue our animals or livestock. So why not rescue food that is going to be wasted? According to the Environmental Protection Agency we waste up to 40% of the food we produce. This translates into an even bigger number of $165 billion dollar loss with 805 million people going hungry according to the Colorado Springs Food Rescue.
Nonprofits have popped up all over the country because of the Federal Law the Bill Emerson Good Samaritan Food Donation Act signed into law by President Bill Clinton in 1996. The Federal Bill Emerson Good Samaritan Food Donation Act protects the donor and the recipient agency against liability, excepting only gross negligence and/or intentional misconduct. Since 1996, many states have passed their own Good Samaritan Laws.
Established nonprofits can collect food from any distributor to any recipients. This leaves the field wide open to supplementing food shortages. This means that restaurants don't have to add left over food to their trash which lowers their waste collection costs. This is a win-win for all involved. A homeless family or a family that has a low-income gets the benefit of a variety of food which was previously unattainable. Think about what your nonprofit can do?

But, oh the fragrance of these takes your memory back to the fragrance of sweet pea flowering vine. Even the flowers seem to match in their structure. That is because they are related both being in the Legume Family. If you were to take a blindfold test, would you know if you were sitting next to a sweet pea or a wisteria vine?
If you are interested in the non-native types, Silky wisteria, Wisteria venusta repels deer, but attracts butterflies. It has a short 6 inch white racemes blooming in May and June which grows to about 32 feet.
The wisteria with a number of cultivated varieties in a number of colored options such as white, lavender, blue and deep purple is the Japanese wisteria, Wisteria floribunda. Anyone living in zones 5 through 9 can enjoy this type with the longest of all the flower racemes reaching up to 3 feet and blooming in May and June. As much as we sell color blends of tulips, annuals, perennials why not blend two or even all three different colors into the appropriate landscape theme.
Last but not least, there is the Chinese wisteria, Wisteria sinensis, with mauve or lilac colored racemes reaching 9 to 12 inches with the exception of one variety, Cooke's Special of 20 inch length racemes. This type will bloom in May and June.
All of these types need full-sun with well-drained soil to grow and an acid to neutral soil pH.
