Bulbs are typically planted in the fall for the next spring. This is because most bulbs need cold temperatures to start the regrowing process, but you have to plant them before the ground gets too hard from freezing temperatures to plant properly. If you live in a warm climate, this means you can wait a little longer than gardeners in more northern areas, and December is a good time for planting. You shouldn't wait any later than December, however, or you won't have enough cold time for the bulbs.
Locate the area where you want to plant the bulbs. Map out the area so that you can determine where you put each type of flower. Mixing the early and late bloomers within the planting area will ensure that you have flowers blooming for several months.
Loosen the soil in the plant bed with a hoe so that you incorporate air back into the soil. Mix in topsoil or organic matter to add nutrients.
Dig holes for the bulbs 6 to 8 inches down and place the bulbs inside with the pointed side up. In some cases the holes might need to be deeper. Base it on the height of the bulb itself. The hole should be at least twice as high as the bulb. Cover them with soil.
Water to moisten the soil.
