All you need is a Tuna fish can, PVC pipe, Spray Paint, Dollar Store or Thrift Store Vase and candles. Beautiful walk way or patio lighting. When I made a few of these for a friends Wedding we spray painted them silver and then accented them with flowers and ribbon. I used Galvanized Pipe which is found in the plumbing department of your local hardware store. I purchased an 8' pipe for around $3.00 and cut them to length.
Baking soda neutralizes the ph in the soil and nothing will grow there. use baking soda around all of the edges of flower beds to keep the grass and weeds from growing into beds. Just sprinkle it onto the soil so that it covers it lightly. Do this twice a year - spring and fall. Awesome!
