What is the gen rule to water plants like roses, orchids, cymbidiums, houseplants, hydrangaes, lilacs, trees? Should I wet the leaves or just the soil? Or what plants should not have the leaves watered?

It's always best to water the soil, not the leaves. Once in a while it's okay to hose the leaves of your plants off, especially during the hot summer months, to discourage insect pests, but for the most part, water the soil and not the foliage. Likewise with houseplants. Orchids especially resent having their leaves wet. For outdoor plants, water deeply once or twice a week. For indoor plants, allow the top half inch of soil to dry out between waterings. Hope this answers your question!
