What’s the problem?
I’m worried my houseplants won’t survive the heat while I’m away. How can I make sure they stay alive?
Diagnosis
Summer can be challenging for houseplants because hotter temperatures, brighter sunlight and longer daylight hours mean they lose moisture more quickly and therefore need more attention. Going away on holiday adds further cause for concern regarding dehydration and heat stress.
Prescription
Before you leave, water your plants thoroughly, then move them away from direct sunlight to reduce evaporation. Grouping plants together and placing shallow trays filled with water and pebbles nearby will provide extra humidity. For longer trips, consider using self-watering devices such as water globes or string systems. Or ask a friend (one with plant experience) to water them periodically. Covering plants (non-succulents only) loosely with clear plastic bags also helps retain moisture.
Prevention
Check the forecast for while you’re away and adapt your practices accordingly. With careful planning, you won’t return to a plant graveyard.
