El Niño Garden Guide: Planting Through a Hot, Dry Spring

Updated September 2026

A hot, dry spring is coming to most of the country. Plant for it, water smarter, and get the block ready before the first heatwave.

The Bureau of Meteorology declared an El Niño in June 2026 and expects it to strengthen through spring and peak late in the year. For most of eastern and southern Australia that means a hotter, drier spring than usual, low river flows, and a bushfire season that starts early. Some regional towns are already on water restrictions. This is the spring to plant with the forecast in front of you, and this guide covers exactly that: what to plant, what to hold back, how to keep a garden alive on less water, and how to get the block ready before the first hot northerly.

What El Niño means in the veggie patch

Three things change. Rain you would normally bank on in October and November may not turn up, so seedlings that usually establish on spring showers will need hand watering from day one. Days run hotter earlier, so crops that bolt or drop flowers in heat get a shorter window. And the soil dries faster than the calendar suggests, which punishes shallow-rooted, thirsty crops most.

The gardens that do well in a dry spring are the ones that pick their battles. Fewer thirsty crops, more heat-lovers, a lot more mulch, and water that goes to the root zone instead of the air.

What to plant this spring (and what to hold)

The exact list depends on where you are. A Brisbane spring and a Hobart spring are different jobs even in the same El Niño. Pick your region below, or open the app and the Plant Now shelf filters this for your climate automatically.

Timing: plant early, or plant late

The mistake in a hot spring is planting on the usual date and watching seedlings hit 35C before their roots are down. Two ways around it:

• Go early. Once your frost risk has passed, get heat-lovers in straight away so they are established before the first real hot spell. Check your postcode in the frost and heat lookup before you commit.
• Go late. Hold cool-season and salad crops for a late-summer sowing that matures into autumn. You lose nothing, you just skip the season that would have killed them.

Plant in the evening or on a cloudy day, never at midday. Water the hole before the seedling goes in, then again after. Shade new transplants for the first three or four days with an upturned pot, a shade cloth tent, or a bit of shade from a taller neighbour.

Water: make every litre count

Restrictions are already in place in parts of inland NSW and Queensland, and the capital cities are reviewing demand measures. Set the garden up now for a summer where the hose is rationed.

Mulch, then mulch again

75 to 100mm of coarse mulch cuts evaporation by more than half and keeps the root zone cooler. Sugar cane, pea straw, lucerne or wood chip all work. Keep it off the stems. Top it up as it breaks down. This is the single highest-return job in a dry spring and it costs almost nothing.

Water the roots, not the air

Drip lines and soaker hoses under the mulch put water where the plant can use it. A sprinkler on a hot afternoon loses a third of what it throws before it hits the ground. If you are hand watering, use a wand at soil level and count to ten per plant.

Deep and less often

A deep soak twice a week grows deep roots. A light sprinkle every day grows shallow roots that fry on the first 40C day. The app shows approximate litres per week for every plant, so you know what "deep" means for a tomato versus a chilli.

Wicking beds and ollas

A wicking bed with a water reservoir underneath uses roughly half the water of a normal raised bed and you fill it once a week. An olla (an unglazed clay pot buried to the neck) does the same job for a single plant or a pot. Both are perfect for the thirsty crops you still want, like cucumber and salad greens.

Catch and reuse

A rain tank on the shed catches whatever does fall. Laundry rinse water and shower buckets are fine on ornamentals and fruit trees; check your state's greywater rules before putting it on veg. Group plants by water need so you are never soaking a rosemary to keep a lettuce alive.

Decide what you will let go

If restrictions bite, have the order worked out in advance: fruit trees and perennials first, then established fruiting crops, then everything else. Annual leafy crops are cheap to replace in autumn. A five-year-old citrus is not.

Heat: protect what you have planted

• Shade cloth at 30 to 50 percent over fruiting crops during heatwaves. Rig it on stakes so air moves underneath. It cuts blossom drop and sunscald more than anything else.
• Move pots. Anything in a container goes to the east side or under a tree on 38C-plus days. Dark pots cook roots; wrap them in shade cloth or hessian.
• Skip the feed. High-nitrogen fertiliser during a heat spell pushes soft growth that scorches. Feed once the weather breaks.
• Water in the morning. Early, deep, done. Evening watering is second best. Midday watering on wet leaves does more harm than good.
• Harden off properly. Seedlings from a nursery have had it easy. Give them a week of increasing sun before they go in the ground.

The Heat & Shade Planner has shade percentages and a heatwave checklist for each region.

Bushfire: get the garden fire-ready early

El Niño springs bring early fire weather. If you are on the urban fringe, in the hills, or anywhere with bush nearby, do this in September, not in December.

• Clear leaf litter, dead growth and dry grass within 20 metres of the house. Keep lawn short.
• Swap flammable mulch (pine bark, straw) for pebbles or gravel within a metre or two of buildings. Keep straw mulch on the veggie beds further out.
• Clean gutters now and again in November. Fit gutter guards if you have not.
• Prune low branches and anything overhanging the roof. Remove ladder fuels that carry fire from the ground into the canopy.
• Store firewood, LPG bottles and timber away from the house.
• Fit a firefighting outlet and a long hose to your rain tank, and check the pump runs without mains power.
• Plant for low flammability near the house: succulents, high-moisture natives, lawn, and deciduous fruit trees. Avoid oily, fine-leafed shrubs against walls.
• Write your bushfire plan with your state fire service (RFS, CFA, QFES, CFS, DFES) and know your trigger to leave.

Chickens, bees and the rest of the block

Heat kills chickens faster than cold. Deep shade, two water sources in the shade, and frozen fruit or a shallow paddling tray on 38C days. Pale birds and heavy breeds suffer first. Bees need a reliable water source within 50 metres of the hive with something to stand on; a bird bath with pebbles works. Both are worth setting up before the first heatwave, and the app's Animal Health and Bees modules keep the checks on your daily list.

Your September to November checklist

• Mulch every bed to 75mm or more.
• Lay drip line or soaker hose under the mulch, on a tap timer.
• Build or convert one wicking bed for thirsty crops.
• Buy shade cloth now, before the first heatwave sells it out.
• Plant heat-lovers as soon as frost risk passes. Hold salad and brassicas for autumn.
• Dig in compost before planting; organic matter holds water like a sponge.
• Check the rain tank, pump, gutters and fire plan.
• Set up shade and extra water for chickens and bees.
• Write down your watering priority order in case restrictions tighten.
