The Royal Horticultural Society has issued advice for UK travellers planning summer holidays, recommending four special measures to protect plants from drying out during higher-than-usual temperatures.
Wick Method for Large Plants
For large single-pot plants, the RHS suggests using the wick method. Place a container of water next to the plant, insert one end of a capillary matting wick into the water, and tuck the other end into the plant pot. This allows the plant to draw water as needed.
Capillary Matting for Small Pots
For smaller potted plants, use capillary matting. Lay a sheet of matting on a kitchen draining board or bath edge, with one end draped into a sink or bath filled with water. Group the plants on the wet matting, pressing them down slightly to ensure good contact. For clay pots, give them a thorough watering first.
Covering Plants
A simple method for short absences is to cover plants with a clear reusable cover or bag, supported by canes to avoid contact with the plant. This retains moisture.
Self-Watering Containers
For plants needing year-round moisture, self-watering containers with built-in reservoirs are recommended. These are best for long-term growth rather than short holiday absences.
