Do this in the fall: Plant bulbs in Pots. Store the potted bulbs in an unheated garage or storage room. You'll need to water every few weeks since the pots won't have access to rainfall. In addition to small pots, pack bulbs "shoulder-to-shoulder" in big containers for an abundant display in spring. Toss aside the spacing recommendations so you can get as many bulbs into the container that will fit.
Baking soda neutralizes the ph in the soil and nothing will grow there. I use baking soda in a 6" wide area around all of the edges of my flower beds to keep the grass and weeds from growing into my beds. Just sprinkle it onto the soil so that it covers it lightly. I usually have to do this twice a year - spring and fall.
