Thanks to their recent rise in popularity and becoming one of the biggest interior trends of the 21st century, indoor plants now don a heftier price tag than ever before.

And if you dream of living in a home that imitates a greenhouse, your bank balance might become a bit of an issue. Fear not, we are here to the rescue.

We’ve unearthed the best places to snag Instagram-worthy It-plants at a fraction of the price of traditional plant stores and nurseries – and in some cases, they’re completely free.

Thanks to a little creativity and resourcefulness, you’ll be living in a jungle-like interior (with a healthy bank account intact) before you can even say monstera deliciosa.

1. Utilise your own garden

If you’re lucky enough to have your own backyard or garden, there’s never been a better place to grow your collection of indoor plants. Consider propagating your own new plants. Many pants are suitable to do this, think succulents, ivy and gardenias, to name a few. It’s time to cut, pot and propagate. For the apartment-dwellers, consider taking cuttings from your existing indoor plants and re-pot them to multiply your collection.

2. Annual and pop-up plant sales

Look out for warehouse-style pop-up plant sales often held in major cities, along with annual plant sales hosted by larger organisations such as the The Royal Botanic Garden Sydney and state plant societies. Expect the range and offering of plants to exceed any nursery or plant store you’ve ever visited. Consult local publications, community Facebook pages and our trusty friend, Google, to stay abreast of these bank account-approved sales.

3. Plant shop sales or discounts

Take those green thumbs of yours to a nursery or plant store a day or two after major plant-giving holidays – like Valentine’s Day, Mother’s Day, Easter or Christmas – when they’re likely have additional or leftover stock to sell at lower prices.

4. Gumtree and Facebook marketplaces

While they may not be the most obvious places to shop for indoor plants, they are undoubtedly one of the best places to uncover the most cost-effective foliage. Search in your local area for “indoor plants” and we guarantee you’ll be surprised at the findings.

5. Facebook “Buy, Swap and Sell” pages

Are you a member of your local “Buy, Swap and Sell” Facebook page? If you’re not, you should be. These pages have been created so people around the world can sell and exchange goods in their own local areas with ease. In addition to the abundance of plants you’re likely to find for sale, or for free, you might also discover some other household bargains while you’re at it.

6. Pot fresh herbs

Buy fresh herbs and pot them. Most herbs grow easily from cuttings if they are planted fresh as soon as possible. This way you can grow herbs like basil, mint, cilantro, parsley, celery, lemon grass and much more for free — plus, they look great, too. A windowsill full of potted herbs? Beautiful and practical!

7. Social media call-out

Why not reach out to your social media network on Facebook and Instagram? An old school friend, an ex-neighbour or your great aunt, could be moving house, re-decorating or decluttering and looking for new owners for their beloved greenery.

8. Join community garden groups

If you have time to volunteer, join community garden groups in your area — you’ll get free plants and seeds, learn new gardening tips and ideas, and meet new fellow green thumbs who share the same interests. It’s a win, win!

9. Flea markets, car boot sales and garage sales

Flea markets, car boot sales and garage sales are a great source for cheap, and sometimes free, plants. Once again, find out when markets and sales are happening in your region via local publications, community Facebook pages and a simple Google search.
