Planting depth is also important. The rule is to dig the hole 2 to 3 times deeper than the largest diameter of the bulb for those 2 inches or more. For small bulbs, 3 to 4 times greater than the diameter. Spacing varies with the species but is generally 1 to 2 inches.

Most large plants can be standalone but massing bulbs is an effective way to really make a statement. Make sure bulbs are installed upright, with soil packed in around them. Keep watered unless adequate rainfall occurs.

Mulch over bulbs before cold temperatures appear. Lift and store tender bulbs in a cool location for wintering inside.
