No. Oriental lilies prefer acidic soil, Asiatic hybrids prefer or tolerate more alkaline conditions, and several other groups grow in a wider range of soils. Check the cultivar label.
Keep soil lightly and consistently moist while shoots grow and bloom, but never waterlog it. Check the root zone and water when it starts to dry; containers usually need more frequent checks than beds.
Remove spent flowers if you do not want seed, but leave green stems and leaves until they yellow and die naturally. The foliage helps replenish the bulb for the next season.

Lily grows best in full sun or light shade, with the root zone kept cool. It also tolerates Partial shade, Dappled shade for woodland groups such as Martagon lilies. Avoid deep shade and exposed, hot root zones.
