Gardening – Sustainable gardening

With the rising cost of living and the escalating fuel crisis, more of us are wondering about our food security, and looking to gardening as a practical way to put food on the table. As it happens you don’t need expensive equipment or a big budget to get started. Sustainable gardening is using what you already have and sourcing plants for free, and this can be both eco-friendly and cost-effective.

One of the easiest ways to begin is by reusing everyday household items. Old buckets, yoghurt containers, milk cartons, tin cans etc, can become pot plants by adding a few drainage holes. Flattened cardboard boxes can be layered to create a weed barrier for grass on the garden, and kitchen scraps such as vegetable peelings and coffee grounds make excellent compost, reducing waste and feeding your soil naturally, so there is no need for chemical fertilisers.

Water is another key part of sustainable gardening. Collecting rainwater in barrels or repurposed containers can significantly reduce water use. Mulching your soil with grass clippings, leaves, or shredded paper helps retain moisture and keeps weeds away.

For those looking to grow vegetables without spending money, there are lots of clever options. Start by regrowing vegetables from scraps. Spring onions, lettuce, celery, and even potatoes can sprout again when placed in water or soil. Seeds can also be saved from supermarket produce like tomatoes, capsicums, and pumpkins, just rinse, dry, and plant. Herbs like mint, basil, and rosemary can be grown from cuttings placed in water until roots develop. Once planted, these can provide a continuous supply of fresh flavours for your kitchen.

Community gardens are another valuable resource like Ōrewa Community Garden or our local seed swap group, offer free seedlings, cuttings, and advice. Most gardeners are happy to share excess plants, especially during peak growing season and are always keen to share tips on growing and propagation. 

Sustainable gardening isn’t just about saving money and keeping food miles down it’s also about creating a cycle of reuse, reducing waste, and building resilience. With a bit of creativity and community anyone can grow their own vegetables for little to no cost and in this time of fuel insecurity your garden might be the most valuable space you have.
