Weeping willows, globe willows, corkscrew willow, cotton wood are all prone to bores than other diseases. They grow in fertile soil with lots of moisture. Never treat tree chemical. Prune as necessary, take out dead diseased limbs, water and fertilize regular. This ensures the tree lasts longer and that the tree is less attractive to insects. Where tomatoes are concerned to avoid sunburn ensure that they are slightly covered with the folding of the plant. High salt level of water or chemicals...
Some of the new poinsettia plants will continue to "bloom" year round, but others need a little encouragement. The blooming is actually leaves of the plant itself. One way of forcing it to change color is to withhold fertilizer and/or light for a time, then put it back into a sunny location and it will begin to bloom. The video also addresses spots on Ligustrum plants. It has to do with cold weather in the winter and lack of nitrogen. There's not much you can do about winter damage, but ferti...
Curtis Smith, Extension Horticulturist, and Rick Daniel, Bernalillo County Horticulture Agent, demonstrate how to prune a peach tree and trim raspberry plants.

To wax a snowboard you will need an iron, board wax, a flat scraper and a buffer pad. First, use the iron to melt the wax. The iron should be hot enough to cause the wax to quickly drip but not hot enough to produce smoke. Iron the wax onto the snowboard by using small concentric circles to melt the wax evenly. Go over spots several times, if necessary. Be sure to use wax that is appropriate for your riding conditions. Scrape the excess wax off of the board. Use a buffer pad like the rough si...
Rick Gore tells us how to stop a horse from walking off when you mount. The reason why a horse walks off when you mount it, it's because you trained it that way, when you've mounted previously you would allow it to mount off. Also when you mount you cause the horse to lose it's balance, and when a horse loses it's balance, it starts to walk a bit to regain it's balance. To stop a horse to from losing it's balance you should square it up, push the horse a little bit and it's feet will square u...
When kicking a soccer ball to achieve the best kick you do not want to kick with your toes, you want to kick where your shoe laces are. To kick the ball you don't want your non kicking foot to far behind the ball because this leads to a toe kick. In fact, you want your non kicking foot to be right beside the ball so that when your kicking foot goes to kick the ball it is not a completed kick. This causes the lace part of your shoe to kick the ball. When kicking with the top of your foot it sh...
This video helps us understand the organic molecules and elimination reaction. Take some sugar in a beaker. Sugar has 12 carbon atoms, 22 hydrogen atoms and 11 atoms of oxygen. The sulphuric acid is poured into the sugar and the color change is observed. The color of the sugar gradually changes into black. The sulphuric acid causes an exothermic reaction which releases a large amount of sulphur dioxide gas. All the water (containing hydrogen and oxygen atoms) is eliminated out of the sugar du...

The shadows look like a casting of the shadows of window blinds over the boy, but is not as realistic as he wants them to be. He then makes a...
Remember: a varial kickflip is basically a pop shove-it with a little more ankle action, so set up like you would for a pop shove-it. Hit the tail as you would for a pop shove-it, and as the board starts to snap up, flick your front foot just like a kickflip. That action will cause the board to flip while the shove-it action from your back foot will make the board turn 180 degrees below you. Don't flick the flip too hard or it will flip away from you like a crazy 4th of July firework. Let the...

I have owned quite the plethora of electronics in my life. A commonality between most of these devices' screens is frozen or dead pixels. This is probably the most annoying thing about buying new hardware—your LCD, or worse, LED display has one or more pixels that continues to stay lit. Most of the time, this will appear in the form of a brightly colored pixel that never changes, or a pixel that never displays the right color. Once you notice it's there, you just can't stop staring at it. It ...
When wet sand along the water's edge at the beach is stepped on, it becomes partially dry in a small area surrounding one's foot. The dry patch is evident as the thin reflective film of water at the surface surrounding your foot is no longer there and has instead been drawn into the bulk of the sand beneath your foot.
