If you have a manageable number of plants, you can buy a water-recycling terrarium or DIY one with a large clear plastic bag and keep them happy for months. Put the open bag on a waterproof floor in a room that will stay at a moderate temperature (cool in summer, warm in winter) and out of direct sun.
Water your plant thoroughly and then cover with a clear plastic bag to just below the lip of the planter, creating a makeshift greenhouse. Make sure to cut a couple slits in the plastic to allow for ample air circulation... plants need to breathe, too!
Plants can go to a maximum of a week without water, however, some plants can go for even longer periods of time, such as for two weeks or even a month. It would depend on the type of plant and its drought tolerance level.
Almost any plant can survive a weekend on its own. Cacti and succulents are adapted to low rainfall and can be left alone for extended periods. Surface to volume ratios make it understandable that a small pot dries out more quickly than a large one.

Move plants to a shady area
Plants in direct sunlight will dry out faster than those in indirect sunlight, so whenever I leave for vacation, I move anything that's by a window to a less sunnier area.
Desert dwellers like succulents are able to store water for long periods of time, and their soil likes to stay dry. When you water your jade plants, for example, feel free to give them a soak, but make sure they dry out completely—wait weeks (or even a month) before watering again.
When plants are not watered properly they wilt. This is because of something called turgor, which is water pressure inside the cells that make up the plant's skeleton. Water enters a plant through its stem and travels up to its leaves.
A few days before they leave he gathers the variety of plants scattered throughout their home and waters them heavily, letting each one drain well. Then he finds all the plastic bags, clear or dark, and begins the process of placing each plant in a bag.
Attach Soaker Hoses to Rain Barrels
And they can be adapted to help keep plants hydrated while you are vacationing. If you have a rain barrel, attach a long soaker hose to it and run it through your garden. The water captured by the barrel will leech out slowly and saturate the ground.
One obvious sign of dead floras is mushy and fragile stems plus roots. Once a plant has reached this stage, no home remedies will save it.
Shower Or Bathtub
The bathtub or shower can be used for watering potted plants while on vacation. Keep indoor plants hydrated for a period of 1 to 2 weeks with this method. You need a shower tray or bathtub for this and some old but clean towels.
Water is life to plants, and they need it regularly. However, certain plants are different. There are some Indoor Plants that Don't Need Water Before a Month and can survive for an extended period, going up to 15-30 days without any struggle!
Drought tolerance is one of the unique features of resurrection plants. They can survive for up to seven years without water in dormancy and lose up to 95% of their moisture content without cell or tissue damage.
Attach a soaker hose to a rain barrel and snake the tubing through your garden. The stored water will slowly run out through the hose and saturate the ground. You still need to water well before you leave, but this method can keep your outdoor plants adequately doused while you enjoy a lengthier vacation.
So long as the soil is not bone dry, your houseplant should be able to survive a week or two without water. If you're really looking for an answer on how long plants can go without water and have no idea what type of plant it is, then somewhere between four days – one month would be safe estimate.
Yes, watering globes actually do work.
That said, they aren't always perfect (read in the next section to see why). They also work better than plant humidifiers as humidifiers usually have a run time of 8-16 hours. Even the biggest one can run only for a maximum of 96 hours.
Checklist. Fill a jar, cup or bottle full of water and place next to your pot, positioning it out of direct sunlight, and elevated so that the mouth of the container is higher than the base of the plant. The longer you are going away for, the larger you will want this container to be.
Yes—you can cut leggy plants back to encourage new stems to sprout, restoring your plants to lushness. Trim any exceptionally long, lanky stems, removing a third of their length and snipping just above a node (the point where leaves grow from the stem).
Whatever you do, do not leave plants in the water permanently. Set a timer if you need to so you won't forget about them.
