Summer often comes with one worry: Will my plants still be alive when I return from holiday?
Modern gardening is less about luck and more about preparation. With a few smart steps before you leave, you can help ensure your plants stay healthy, cool and green until you return.
1. Create Shade and Group Plants Together
The most effective way to reduce water needs is to limit transpiration and evaporation.
- Move plants into the shade: Relocate pots from sunny windowsills and west-facing balconies to cooler areas with indirect light.
- Group plants by water needs (hydro-grouping): Place pots close together. As moisture evaporates from the leaves, it creates a beneficial humid microclimate.
Extra tip: Place the most sensitive plants in the middle of the group and hardier plants around the outside to act as a protective barrier.
2. Passive Watering Systems for Short Absences
If you will be away for only a few days and do not have automatic irrigation, several simple alternatives can help.
- Moisture-retaining base: Place a moisture-holding fabric or thick wet towel in a bathtub or tray, with one end touching water. Put the pots on top without saucers. The roots will gradually absorb moisture through the drainage holes.
- Cotton wick method: Place a water container above the level of the pots. Put one end of a cotton string in the water and bury the other deep into the soil.
- Inverted bottles: Fill plastic bottles with water, make a small hole in each cap and insert them upside down into already-watered soil.
3. Check Automatic Irrigation Systems
If you use automatic watering, do not assume everything is working correctly.
- Inspect drippers 48 hours before leaving: Mineral deposits can block them.
- Replace batteries: Change the timer batteries even if they still appear to have charge.
- Schedule watering at cooler times: Water early in the morning (5am to 7am) or late in the evening to reduce evaporation.
4. Use Mulch to Retain Moisture
Bare soil dries out quickly under the August sun.
- Water deeply before departure: Thoroughly soak the soil the day before leaving.
- Apply mulch: Cover the soil surface with a 3 to 5cm layer of pine bark, straw or compost.
Mulch significantly reduces water loss, keeps root temperatures lower, sometimes by as much as 5°C, and prevents the formation of a hard surface crust.
5. Prepare Plants Before You Leave
Give your plants a final tidy-up before your holiday.
- Prune and deadhead: Remove faded flowers, mature buds and dry leaves. Blooms consume valuable energy and water needed for survival.
- Avoid fertilising: Do not apply fertiliser for at least 10 to 15 days before departure. Fertiliser stimulates new growth, which increases water demand and makes plants more vulnerable to heat stress.
6. Train Your Plant Sitter
If a friend or neighbour is helping, keep instructions simple.
- Sort plants into groups: Separate thirsty plants such as hydrangeas, ferns, vegetables and roses from drought-tolerant plants such as succulents, cacti and sansevierias.
- Provide clear guidance: Remind them that overwatering is often the biggest mistake. Slight thirst is usually less harmful than waterlogged roots.
Some of these tips may sound familiar, but during a heatwave they can make the difference between returning to a balcony full of healthy greenery or finding wilted plants struggling to survive.
