How to plant lilies?
Dig a generous planting hole 8” deep. Put some all-purpose fertilizer in the bottom of the hole and mix it around to disperse. Add a few handfuls of loose soil back into the hole and then position the bulbs so they're 6 to 7 inches deep (follow instructions on the packaging). Lilies also grow well in pots.
