Due to their contained growing environment, potted plants need frequent watering to survive. This poses a problem anytime you go on vacation and can't tend to your indoor plants daily. Besides hiring someone to visit your home to water the plants, several management strategies can help you keep your indoor plants hydrated while you're gone.
Repot your indoor plants in a light-colored plastic pot. Light colors deflect heat to keep plants cool and lower moisture loss caused by heat-related evaporation. Plastic also retains moisture much better than porous material like clay pots.
Set the potted plants away from direct sunlight or any sort of heating or air conditioning appliance.
Add polymer crystals, available from most garden stores, to your potted plant's soil. The crystals absorb water and slowly release it over time, and CBS News reports that such polymers reduce the water needs of potted plants by up to 50 percent. Insert a pencil three or four times around your potted plant, making holes that go down to the plant's root network. Pour the polymer crystals into the holes and cover them with a layer of potting soil. Every time you water the plants, the crystals will absorb moisture and release the moisture as the surrounding dirt dries.
Construct a self-watering system for extended vacations. Fill a bathtub or several large containers with a couple of inches of water. Turn a wire dish rack upside down and place your potted plants on the rack so that their bottoms are exposed. Insert a shoelace an inch into the bottom of each pot's drainage hole and place the other end of the shoelace into the bathtub or container of water. As the pot's soil dries, it will naturally draw moisture through the shoelace, according to the University of Minnesota.
Water the potted plants right before you leave for your vacation.
