Watering plants while away

Move the plants out of direct sun, a few feet further into the room. Less light and less warmth cut the water use noticeably while you are away, and most species take a few weeks of weaker light without harm.

Stand the pots together in a group. The air between closely spaced plants dries out less, and all your tubes and cones sit in one place. Keep tilted windows and balcony doors shut, because a draft dries the pots out faster.

On the day you leave, check every pot rather than watering them all. Water a plant only if its mix is dry at the depth its care guide names, until water runs out of the bottom, then empty the saucer. Plants that are still moist, succulents, cacti and plants in a winter rest stay as they are. A saucer left full as a reserve is a bad idea, because the roots get no air for days.

Take off spent flowers, buds and damaged leaves. They use water and will be past saving when you return. Skip fertilizer in the two weeks before the trip, and put repotting off until afterward.

For seven days most houseplants need nothing more than that check before you go. Succulents, snake plants, ZZ plants and cacti last longer than that anyway and need nothing at all for a week.

Ferns, calatheas and small pots can need attention even on a short trip. Check freshly repotted plants separately because unrooted mix may stay wet longer than the old root ball. Set up extra water only for pots that actually dry quickly.

A clay cone sits in the soil and connects by a tube to a bottle of water. As long as the soil around the cone is dry it draws water through the clay wall, and the flow slows once that soil is wet. That makes cones usable for two to three weeks if the reservoir is big enough.

Glass globes work on the same idea but give up their water without the resistance of the clay. In loose soil a globe sometimes empties in a day, and in dense soil the neck clogs with mix. Fill it with clear water and push it into a hole you have watered first, so the opening stays clear.

Measure both before you go. Put the cone or globe in a week ahead and mark the water level on the bottle with a pen each day. The daily use tells you whether the reservoir covers your trip or whether you need a bigger bottle.

In wick watering an absorbent cord of cotton or felt runs from a container of water into the soil. The cord carries water along by capillary action, and the supply stops once the mix is saturated.

The container stands level with the pot or slightly higher, and the end of the cord lies on the bottom of the container. Push the other end a couple of inches into the soil beside the root ball rather than laying it flat on top. On a large pot, run two cords on opposite sides.

Wet the cord through once before you set it up. A dry cotton cord sometimes never starts to draw, and then the container still stands full beside a pot that dried out two weeks ago.

A capillary mat does the same for several plants at once. The pots stand on the mat, one end hangs into a tray of water, and the pots need open drainage holes with no cachepot.

A set with a pump, a timer and thin distribution tubes supplies ten or twenty pots. It suits longer trips and collections that cones can no longer cover.

In exchange it has more that can fail. A tube end slips out of a pot, a dripper blocks, the bucket runs dry, or the power goes out. Run the system for at least a week before you leave and look at each pot individually, rather than only checking that the pump starts.

Set the run time on the short side. Over two weeks too much water does more damage than too little, because permanently wet soil rots the roots. A shallow tray under the pots also catches what a loose tube would otherwise spread across the floor.

A winter trip is a different job from summer preparation. The RHS says most houseplants can be left for a week or two in winter with no attention, as long as the room does not fall below the lowest temperature they tolerate. Cold, not thirst, is the main risk.

Before you leave:

• Set the heating so the coolest room with plants stays above the lowest temperature in each plant’s care guide. Do not switch it off.
• Move plants off cold windowsills, a little way into the room, as the RHS advises. Do not close curtains in front of them, because that shuts them in against cold glass.
• Keep them away from radiators too. Pots dry fast there, and spider mites thrive in warm, dry air.
• Check the soil of each plant and water only the ones that are dry at the depth their care guide names, so the mix is moist but not waterlogged. Succulents, cacti and plants in a winter rest stay dry.
• For a trip of up to two weeks, most plants need no watering aid in winter. Use cones or wicks only for pots you know dry out fast.
• Flowering winter plants such as poinsettia, cyclamen and amaryllis are in growth now. Check each against its own care guide before you go.
• Away for longer than about two weeks? Ask someone to check the plants, as the RHS suggests, and leave them a note or the guide below.
• When you get back, feel each pot before you water anything.

Standing plants in a bathtub or shower filled with water ends after a few days in soaked root balls with no air. A short soak followed by draining is a different thing from three weeks in water.

Pulling a plastic bag over the whole plant does hold the humidity up, but in a warm summer room it traps heat and condensation and rots the leaves.

Wet newspaper and towels on the soil dry out themselves within a few days. They slow the drying a little and replace no water source. A layer of bark mulch or expanded clay on the surface likewise only slows evaporation part of the way.

A person is the safest answer on a longer trip, though helpful neighbors tend to water too much. So leave a short note that says, per plant, how deep to feel and what to do when the soil is dry there.

Write the instruction as a check and not as an appointment. A line like "push a finger an inch or two into the soil, water only if it is dry down there, then empty the saucer" can be carried out, while "water twice a week" means something different in every pot.

Put a label on each pot and move the plants that rarely want water into another room. Snake plants and cacti are best kept out of the way so they do not get watered along with the rest.

Botanicaly Pro includes a Plant-sitter Guide, a plain-text care sheet for whoever looks after your plants. It is built from the plants you saved in the app, grouped by room, with each plant’s next soil check for your trip dates, how often to check again on a longer trip, its light, a pet warning where one applies and your latest note.

This is what it produces for a winter trip with three plants. The dates belong to the example.

Made with Botanicaly

Open Settings in the app and tap Plant-sitter Guide under Care. Pick the From and Until dates, choose which plants to include and tap Share guide.

The guide goes out as text through your phone’s share sheet, so the sitter does not need the app. It does not update after sharing, so share a new one if your plans or a plant’s care change.

Without Pro, the note from the section on when someone stops by does the same job. Write each plant’s check, depth and pet warning on one sheet and leave it by the plants.
