Answer: Salvias like dryish soils so you may be overwatering them. Although the weather is hot, your soil probably holds moisture for a long time. The best way to provide adequate water is to water slowly so it can soak in and then wait a day or two and dig down into the soil to see how wet it still is. If the soil is still moist an inch below the surface you won't need to water for a few more days. If it is dry, it's time to water. You can prune your salvias back to encourage healthy new growth. Once you adjust your watering, your salvias should perk up.
Lilies bloom only once during the season. Leave them alone until the tops die down (late summer) then cut off the dead foliage. You don't need to dig them up and store them - just leave them in the ground and lay a mulch over the top to protect them this winter.
