Setting Up Your Garden to Survive the Christmas Holiday
It’s the most dangerous fortnight of the year for Peninsula gardens. You’re away, the temperatures climb, nobody’s watering, and by the time you get home half the garden looks like it’s been through a bushfire.
A bit of preparation before you leave makes all the difference.
Water Deeply Before You Go
The day before you leave, give every garden bed a long, deep soak. Not a quick sprinkle — a proper 30-minute soaking that gets water down deep into the soil. For sandy Peninsula soil, this might mean running drippers or a slow trickle from the hose, moving it from bed to bed.
Deep water encourages roots to go deep, where moisture persists longer. Surface watering trains roots to stay shallow, right where they’ll dry out first.
Check Your Irrigation Timer
If you’ve got an automatic system, now is the time to check it’s actually working. Run every zone manually and walk around checking for blocked drippers, leaking connections, and dry patches.
Set your timer to water deeply every two to three days rather than lightly every day. Early morning (5 or 6 AM) is the best time — less evaporation and plants go into the heat of the day with wet roots.
If you don’t have a timer, a simple battery-operated one from the hardware store costs about $30 and connects to any garden tap. Worth every cent for peace of mind over the holidays.
Move Pots Into Shade
Potted plants are the first casualties of a heatwave. Pots heat up in direct sun, cooking roots, and small pots dry out in a single hot afternoon.
Before you leave, group your pots together in the shadiest spot available — against a south-facing wall, under a tree, or under the eaves. Grouping them together creates a humid microclimate that slows moisture loss. Sit them in saucers so runoff water collects and gets reabsorbed.
For larger pots you can’t move, wrap the outside with hessian or bubble wrap to insulate them from direct sun.
Mulch Like Your Plants’ Lives Depend on It
Because they do. If your mulch has thinned, top it up to a full 7 to 10 centimetres before you leave. Focus on garden beds and around the base of any trees or shrubs that are less than two years old — these haven’t developed deep enough roots to handle extended dry spells.
Harvest and Deadhead
Pick any ripe fruit, vegetables, or flowers. Fruit left on the tree attracts possums and rats. Spent flowers divert energy into seed production instead of survival. Cut back any annuals that are looking leggy — they’ll often push out fresh growth when you start watering again.
Ask a Neighbour
The old-fashioned solution is still the best one. A neighbour willing to check on the garden every few days and give things a water during a heatwave is worth more than the fanciest irrigation system.
Return the favour when they go away. This is how Peninsula communities have kept gardens alive for generations.
When You Get Home
Don’t panic if things look rough. Most established plants recover well from a couple of weeks of neglect. Give everything a deep soak, assess any damage after a few days, and hold off on pruning dead-looking material for at least a fortnight. Many plants that look dead will reshoot from the base once they’re watered again.
