Spring Clean Your Plants!

Before we dive into the how-to, let's talk about why a thorough spring clean is crucial for the success of your plants. Our unique climate means we're dealing with:

Extreme seasonal changes that stress indoor plants more than in temperate climates

Dust storms and bushfire smoke that settle on leaves and clog plant pores

Dry indoor air from heating and cooling systems that creates perfect conditions for dust buildup

Extended periods indoors where plant health directly impacts your family's air quality

When plants can't breathe properly, they can't filter air effectively. That means less oxygen production and reduced removal of common household toxins like formaldehyde and benzene – stuff that's particularly important in homes with kids and pets.

The Three-Step Spring Clean: Prune, Dust, and Protect

Step 1: Prune Like You Mean It

Dead leaves = dead energy (and potential pest problems)

Those crispy edges and yellowing leaves aren't just ugly – they're energy drains that can attract pests and disease. In Australian conditions, where humidity fluctuates wildly, dead plant matter becomes a breeding ground for fungal issues that can spread throughout your collection.

What you'll need:

How to prune properly:

  • Sterilise your tools with rubbing alcohol between plants to stop spreading any fungal issues or diseases.
  • Cut just above the node (where leaf meets stem) at a 45-degree angle to help reduce the risk of water pooling.
  • Remove no more than 25% of the plant at once to avoid shock. If your plant needs a big prune, it’s best to space it out to allow the plant a chance to recover!
  • Focus on diseased, damaged, or dead material first

Pro tip: Many plants will propagate from healthy cuttings! Pop them in water and you've got free plants for mates or other rooms.

And if you’ve ever struggled with tricky drama queens like Calatheas, don’t worry—we’ve got you covered. Why Your Calathea's Leaves Curl—And How to Fix It (Plus Keep Your Family Safe from Chemicals) breaks down exactly what’s going on and how to fix it without resorting to harsh sprays.

Step 2: Dust Like Your Plants Health Depends On It (Because It Does)

Here's what most people don't know: Just a 0.5mm layer of dust can reduce a plant's light intake by over 40%. That's like forcing your green gang to work in sunglasses indoors – no wonder they're struggling!

In Australian homes, dust isn't just household debris. It's often mixed with fine particles from bushfire smoke, pollen, and red dirt that can really clog up those leaf pores. When plants can't photosynthesise properly, they can't clean your air effectively.

The game-changer: GreenSpace Reset Leaf Conditioner – this Aussie-made solution does the heavy lifting for you. Unlike generic cleaners, Reset breaks down that stubborn Aussie dust and grime while conditioning the leaves. The best part? It's so effective you don't even need to wipe it off most plants – just spray and let it work its magic.

For delicate or fuzzy-leafed plants: Use a soft, dry brush instead of wiping. A clean makeup brush works perfectly for African violets and other sensitive species.

Choose the right cleaning method for your plant

Not all leaves like being cleaned the same way. Matching the method to the plant (and the mess) helps you avoid damage while getting better results.

Large, sturdy plants (fiddle leaf figs, monsteras, palms)
If your plant is too big to wipe leaf by leaf, a gentle shower works well. Take it outside or pop it in the shower and rinse with lukewarm water. Keep the pressure low and let excess water drip off before returning it indoors.

Light dust build-up
For everyday dust, a soft microfibre cloth or feather duster is usually enough. Support the leaf with one hand and wipe from the base to the tip. Don’t forget the underside — that’s where dust and pests like to hide.

Sticky residue or pest mess
If leaves feel tacky or grimy, mix a small amount of mild liquid soap with water. Dampen a soft sponge or cloth and gently wipe each leaf, supporting it as you go. Rinse with clean water afterwards to remove any soap residue.

Delicate or fuzzy leaves (ferns, begonias, African violets)
Avoid wiping these. Use a soft paintbrush or makeup brush to lift dust instead. Water can cause clumping or spotting on textured leaves.

Succulents, cacti and bonsai
Skip wiping altogether. A gentle mist, soft brush or low-pressure air (like a camera blower) works best without damaging the plant’s surface.

Step 3: Protect and Shine (The Natural Way)

Now for the finishing touch that'll make your plants glow

This isn't about making leaves artificially shiny – it's about creating a protective barrier that helps plants cope with Australian conditions while deterring pests.

Enter neem oil – the natural multi-tasker that Australian gardeners swear by. Our Neem + Karanj Oil blend is cold-pressed and perfect for Australian conditions:

  • Natural pest deterrent for spider mites, aphids, and scale
  • Fungal protection crucial in our humid seasons
  • Subtle, natural sheen that indicates healthy, protected leaves
  • Safe for families and pets when used as directed

How to apply:

  • Mix according to label directions (usually 1-2ml per litre of water)
  • Spray lightly in the morning so plants can dry before evening
  • Focus on leaf undersides where pests love to hide
  • Reapply every 2-3 weeks for ongoing protection

How often should you clean your indoor plants?

There’s no single schedule that suits every home, but these guidelines work well for most indoor jungles:

  • Light dusting: about once a week
  • Deeper leaf clean: every 3–4 weeks
  • Extra attention needed if:
    • Your home gets a lot of dust or traffic
    • Plants sit near open windows, air-conditioning or heaters
    • You live in a dry or smoky area

If leaves look dull, feel dusty, or water starts beading unevenly on the surface, it’s usually time for a clean.

A quick word of caution

When cleaning leaves, less is more. Avoid harsh chemicals or household cleaners — these can damage the leaf surface and interfere with photosynthesis.

Skip products that contain:

  • Alcohol
  • Ammonia
  • Strong detergents or disinfectants

Signs a leaf hasn’t liked being cleaned:

  • Brown or scorched patches
  • Yellowing shortly after cleaning
  • A dull or sticky film that doesn’t wash off

If that happens, rinse the plant with clean water and let it dry naturally.

The Science Behind Healthier Plants

When you give your plants this three-step treatment, you're not just improving their appearance – you're optimising their ability to:

  • Increase oxygen production by up to 30% (healthier plants = more photosynthesis)
  • Remove more toxins from your indoor air, including formaldehyde and benzene
  • Regulate humidity more effectively, crucial in Australia's dry climate
  • Resist pests naturally, reducing the need for chemical interventions around your family

Go Beyond the Basics & Build Long-Term Plant Health

Once you've done the initial spring clean, maintain that health boost with:

Go beyond the leaves: a full spring reset for indoor plants

A proper spring clean isn’t just about shiny leaves. While you’re already hands-on, it’s the perfect time to check a few other things.

Before cleaning

  • Look for pests under leaves and along stems
  • Trim away dead or damaged growth
  • Check if roots are circling the pot or pushing up the soil

During your clean

  • Wipe down the pot and saucer
  • Flush the soil gently with water to remove built-up salts (do this outside or in the sink)
  • Top up potting mix if it has settled

Spring tune-ups

  • Consider repotting plants that have outgrown their containers
  • Add stakes or supports to climbing plants like monsteras
  • Re-position plants as daylight hours change, keeping them clear of heaters and air-con vents

These small checks help plants bounce back faster as growth picks up.

FAQ

Can I just use water to clean leaves?

Yes. For most plants, clean water and a soft cloth are all you need for regular maintenance.

Do I need to clean the underside of leaves?

It’s a good idea. Dust and pests often settle underneath, and cleaning both sides helps the plant breathe properly.

Is dish soap safe for plants?

Only in very small amounts, and only occasionally. Always dilute it heavily and rinse the leaves afterwards.

Should I use neem oil when cleaning?

Neem is best used for pest control, not routine cleaning. If you’re not dealing with insects, stick to water.

What about milk, lemon juice or other online hacks?

These can leave residue and do more harm than good. Simple, gentle methods are safer and more effective long-term.
