Trees
Above ground, trees and shrubs perform important environmental services by providing food and shelter to people and wildlife, oxygenating the air, and beautifying the landscape. Below ground, their roots open up critical passageways for the movement of air, moisture, and soil food web members.

Can I use Dish detergent to kill insects on plants?
Detergent no, liquid soap yes.
Soap has been used as a natural insecticide for years the trick is not to use too much or you will kill the leaves as well, the way it works is that it disrupts the insects cell membranes, and kills pests by dehydration.
Buy a liquid soap and not a detergent, something like Dr. Bronner's Pure-Castile Soap can be found in health food stores. mix 1 to 2 tablespoons liquid soap to 1 quart of water
What trees grow flowers on them?
Plants are divided into two broad categories:
Gymnosperms - which produce cones (like a pine tree) and
Angiosperms - which produce flowers
Angiosperms are further divided into two main groups of plants: the dicotyledonous plants and the monocotyledonous plants.
Both gymnosperms and angiosperms can be classified as well according to their growth habit - Evergreen (or plants which retain their leaves all year round) and Deciduous (plants which drop their leaves during autumn/ fall, are bare through winter and then re-grow their leaves during spring.
All Angiosperm trees have flowers, some aren't very big or noticeable but then some are gorgeous.
Angiosperms do not have flowers, they have cones, deciduous plants have flowers.
Binary Search trees offer improved average case performance for searching. However, if they are unbalanced their search performance degrades to that of a linked list. AVL trees guarantee that the difference in height of any two subtrees rooted at the same node will be at most one. This guarantees an asymptotic running time of O(log(n)) as opposed to O(n) in the case of a standard bst.
What is the formal name of the Polish-Russian calvary?
1. Samodzielna Warzawska Brygada Kawalerii
The 1. Samodzielna Warzawska Brygada Kawalerii -was a cavalry brigade fighting on the side of the Soviet Union as part of the 1. Armia WP, the 1st Polish People's Army.
Poland still used mounted troops during the early part of WW2. After release from Russian prisoner of war camps, the Poles still fought as an exiled Army and were armed by the British and US. The lancer units transitioned into armored units.
Origin of Lancers
The Lancer soldier dates back many years but it was the Polish Lancers who became most famous for using this type of cavalry soldier during the Napoleonic Wars(1798-1815). The Polish Lancer uniform and the "Chapka" hat (or czapka, shapka, or tschapka)became the identifier for a lancer soldier. The coat had two rows of buttons with a turned back front of facing colors. The Chapka was a skull cap that had a crown that rose to a square top (Polish jokes aside, it is odd that the Polish could design a square hat). This same pattern uniform & cap were worn by the British 17th Lancers during the "Charge of the Light Brigade" in 1850's Crimean War.
Another item introduced by the Polish lancers were the Red/White banner(guidon) attached to the end of their lance. A squadron of lancers riding in a trot with fluttering guidons made for a spectacular sight in parade or in battle.
Napoleon liked the light cavalry units so much that he created other similar units that had similar names:
Lithuanian Tartars were a light cavlary armed with a lance and wore a light jacket and turban of Lithuania. They were attached to the Polish Lancer regiment.
Eclaireurs were another light cavalry unit that wore the typical French uniform and a cylindrical shako.
WordsThe Polish word for lancer is "Ulanow".Germany - The German term was "uhlan".
Baron von Richthofen(aka "the red baron") was a member of the 1st Uhlan Regiment before the joined the Air Force and became the highest ranking ace of WW1.
Russia - As far as I know, there was no special term for lancer but just a translation of the term.

Seasoning of timber is the drying of timbers moisture content to a level below 22% by several methods, including Air seasoning, kiln seasoning or a combined of both.
Seasoning of timber allows wood to be used for practical purposes whether it be for shaping, constructional purposes, what ever the need for timber, it must be seasoned.

What kind of wood is used to make violin bows?
The unbacked self-bow used by the Native Americans for hunting was composed of almost every type of wood known, softwood and hardwood. Self-bows are bows made from one single piece of wood, so it's not the type of wood that is too critical but how many knots and how tight the growth rings are, the grain straight, ect.. The best two woods utilized for making primitive wooden bows are Yew and Osage Orange. Yew is a very soft wood, but the fibers are highly elastic and can resist tension, which is the force acting on the back of the bow. Osage Orange is really hard, tough wood and makes a really good bow. But other woods can be used- Black and White Birch, Ash, Hickory, Hazel, Spruce, Mulberry, Oak, Walnut, and almost every species of hardwood. Softer woods like Willow, Poplar, and most Conifers are brittle and weak woods, but you can still make a good bow from them if you make the limbs very wide and the bow thin.
What is the moisture content in boards?
determine the feasibility of commercial, off-the-shelf, and potentially low-cost ultra-wideband radio hardware to serve as a measurement tool for the moisture content of building materials. The study examined both reflections from and transmission through an envelope assembly when pulses with a center frequency of 4.7 GHz were emitted towards the materials. The reflected energy was found to be the best measure of moisture content. Tests on oriented strand board, plywood, and gypsum board showed that a linear trend was found between the reflected energy and moisture content of the two wood products, but the range of moisture contents in the gypsum boards was insufficient to have any appreciable effect on the signal returned. The ability to independently measure the moisture content of several layers with a single scan was also examined, but the data suggest that more work is needed to accomplish this goal.

How do you identify shrubbery?
Try matching the leaves in a gardening book, or take a cutting to a local nursery for identification.
As long as you have the original tree, it's going to sucker. If you keep the tree (or if the tree is in a neighbor's yard), the best you can do is continue to be vigilant with pulling or mowing the suckers.
If you're getting rid of all of it, pull slowly on green suckers to remove as much of the root as possible. Cut woody stems as low as you can (if already cut, make a fresh cut) and use Brush B Gone or a similar herbicide. This will get into the shared root system, so do not use it if you're trying to keep the main tree.
We're currently fighting sumac in a side yard covered with landscaping rock. We'll need to rake out the rock, pull and treat the sumac, and then cover the area with plastic sheeting and replace the rock.

well most grow in summer easy, but I'm not sure so if you know the answer is different,please edit.
When can the cassia tree be transplanted?
I have transplanted two different casssia trees at different times of the year, they are very hardy trees if you live in the southeast. They grow very quickly. make certain the roots are covered with soild and that the soil stays moist for the first few weeks. I also fertilize with milorganite regularly
