Managing a collection of over 10 houseplants is rewarding, until you plan a getaway and realize you have no one to watch them.

Asking a neighbour to tend to a full indoor jungle feels like a huge ask, but going sitterless doesn’t mean leaving your greenery to wither. Over the years, I’ve refined a low-effort prep routine that successfully keeps every single pot in my home alive and well until I return.

In fact, after my last trip, my spring onions had sprouted higher than ever! Whether you’re heading off for a short weekend break or an extended summer vacation, here is the exact strategy I use to holiday-proof my entire collection without calling in favors.

1. Relocate and group your plants

Move your pots back from sunny window sills into the interior of the room. When plants receive less direct sunlight, their metabolism slows down, meaning they drink much less water.

Grouping them close together also creates a microclimate: as water evaporates from the foliage and soil, it builds a localized moisture bubble of humidity that keeps all of them happier for longer.

2. Give them a thorough soak

Water your plants deeply until liquid runs freely out of the drainage holes at the bottom of the pots. Crucially, let the pots drain completely in the sink or tub before returning them to their saucers.

You want fully saturated soil, not stagnant water that rots the roots.

3. Hold the fertiliser

Your instinct might be to give your plants a little extra food before you go to keep them strong, but resist the urge. Fertiliser encourages active, rapid growth, which makes plants significantly thirstier and rapidly drains the moisture from their soil. Save the plant food for when you get back.

4. Inspect and clean the foliage

Wipe down both sides of the leaves with a damp cloth to clear away dust, looking closely for any lingering pests like spider mites or mealybugs. Unchecked bugs can multiply rapidly and cause serious damage when there’s no one around to catch them early.

5. Mulch the topsoil

Add a thin layer of mulch right on top of the soil — think of it as tucking your plant in before you leave!

Choose damp sphagnum moss for moisture-loving tropicals (like ferns or peace lilies), bark chips for chunky-soil lovers (like monsteras or philodendrons), or pebble mulch for indoor succulents and snake plants.

This protective layer traps soil moisture, dramatically slowing down evaporation.

For longer trips…

If you prefer a ready-made solution over DIY hacks, decorative glass or plastic watering globes are a brilliant, battery-free gadget for frequent travelers. Simply fill the globe with water, use a pencil to make a small pilot hole in the moist soil, and insert the stem near the base of the plant at a slight angle.

Like a drip irrigation system, the globe slowly dispenses water as the soil dries, allowing the roots to absorb moisture as needed without the risk of waterlogging.
