If using a hose consider a hose reel , either one mounted near your spigot or the cart type my personal favorite. A dial attachment gives you the option to mist those plants that need a delicate watering and blast the aphids or spider mites with a jet stream. A wand is handy for hanging plants or high shrubs. Soaker hoses , or drip irrigation systems use less water than traditional sprinkler systems or hand watering, operate at a lower pressure, and of course cut down on the work involved in maintaining a garden. The down side is that they can be expensive to install and maintain, but they deep water, therefore providing moisture where it is most needed the roots and create healthy plants.
Most plants prefer a humid environment.
This is easily accomplished with a mister or a humidity tray. A mister can be obtained from a local nursery or you can use an all-purpose spray bottle as long as it produces a fine cloud of moisture that surrounds the plant and covers both sides of the leaves. Do not mist fuzzy-leafed plants. Water is added until just below the top of the rocks and the potted plant is placed on top. Additional water is added as necessary.
