Help your garden become a lush paradise using these garden care tips


So you already have a garden. Fantastic! Why not help your garden become even better with a bit of TLC? Give your students the task of caring for your edible or native gardens, turning them into healthy and productive gardens with benefits for your school, your students and our environment.

Looking after your plants will reap long-term rewards, save your school money and save precious water.

How To Do It

Get into the garden

What does looking after your garden involve? Any, several or many of the following options will help your garden to flourish:


Mulching around the base of larger plants and in garden beds will help retain water and keep the soil moist. Good for worms, good for soil, good for plants! Just be aware that some mulching materials (such as pea straw) may contain snail eggs – not ideal for a veggie garden.

Plant food

Plants get hungry too, especially those in poor soils or pots. Give your plants some food such as fertilizer or manure. Yum yum yum!


Composting food waste to add to your garden is a great way to keep soils healthy, plants happy AND stop your food scraps going to landfill.

Worm wee

Worms love food scraps and gardens love worm wee! Start a worm farm and save the wee to add to your garden, although you will need to dilute it first – 1 part worm wee to 15-20 parts worm wee.

Pest control

Pests can be a problem and if you want to keep the birds, bugs and kids happy then you probably don’t want to use chemical-based pesticides. Try some natural pest controls instead.

Companion planting

Most plants need friends and some friends are better than others. Good friends help to fight off the pests and help plants grow bigger and better; bad friends mean plants struggle. Sustainable Gardening Australia have a comprehensive list of plants and their best buddies (and enemies). Learn more here. 

Green manure

It sounds awful, doesn’t it? But it’s actually very nice. Green manure crops are crops you plant in your garden for the sole benefit of improving your soil. These are annual fast growing crops, usually a legume combined with a grass, that are grown to build both organic matter and nitrogen levels to improve the soil. You can’t harvest any food or flowers from them but they will improve your next season’s veggie crops. You can buy green manure seeds online or at your nursery.


Don’t forget to water your plants! However, there are plenty of ways to water your plants without blowing the budget. You can water your garden with water left over from painting, water activities and food preparation (such as washing veggies or running the water when filling the sink).

Talk to your plants!

Studies have shown that plants respond positively to happy and encouraging verbal reinforcement, including singing.

Quick tips:

  • Parents/caregivers can collect materials, cuttings and donate time.
  • Keep a box of gardening tools and gloves for children of all ages to use.

Whole centre tip

Children of different ages and abilities can be assigned different garden care tasks. Older children can help with mulching or feeding plants while younger children can water plants and talk to plants!


What’s Our Impact?

A mature tree absorbs an average of 267kg over its lifetime (30 years). Each year a tree absorbs 8.9kgs of CO2-3 (267kg divided by 30). These savings are based on planting and looking after one tree. All plants benefit the environment. Plant more, save more!

  • CO2e (weekly) 0.17
  • CO2e (annual) 8.9
  • Black balloons (weekly) 3.4
  • Black balloons (annual) 178

Further opportunities for learning include an introduction to the seasons, plant lifecycles, natural packaging, needs/care/parts of a plant, and textures, shapes, smells and colours of plants.


Fast Facts

Mulch stops the top of the soil drying out, keeps the soil moist, and can reduce watering by about 60%. Learn more at the ABC.

Many of the modern principles of companion planting were present many centuries ago in cottage gardens in England and home gardens in Asia, and thousands of years ago in Mesoamerica.
