“Schooling up and laying the correct groundwork for your indoor jungle is the best way to create a sustainable and ultimately rewarding plant-filled space,” write Lauren Camilleri and Sophia Kaplan, owners of Sydney plant-delivery company Leaf Supply. “Knowing exactly what plants need to survive, as well as what conditions they will receive in your interior, will allow you to make informed decisions about the style of jungle that is best suited to you.”

Here are some extracts from their second book, Indoor Jungle, to help get you started.

Analysing your space
When it comes to creating an indoor jungle, well before you hit the nurseries and plant shops, it’s really important to understand the space you’re dealing with. To give plants the best chance to survive you need to be realistic about the conditions you’re able to provide. When bringing plants into our spaces, we’re looking to mimic as closely as possible the conditions they receive in their natural environment. At the top of the list of considerations is the level and type of light on offer, but that’s closely followed by water and soil as well as temperature, humidity and fertiliser.

Spend time throughout your day watching the sun as it moves across the sky and peeks through different windows. Where does the light reach? Do certain rooms get extra hot in the afternoon sun? Do these patterns change in the cooler months? Do you have air conditioning or heaters? Or a strong draught down particular corridors? Keep all of this in mind when you’re considering where to place your plants.

From here you can look more closely at which areas you’d like to fill. Is there an empty corner that could be brought to life? A shelf or bookcase that could benefit from trailing plants? A windowsill that’s screaming out for some plant love?

Finding inspiration
There’s no shortage of places to find green inspiration when searching for ideas to create your own indoor jungle. We’re stickybeaks from way back and love nothing more than peeking inside the spaces of amazingly creative plant people to swoon over how they’ve incorporated plants into their stylish spaces. Chatting to the people who inhabit these lush interiors about how they’ve built their jungles, where they get their love of plants, and – most importantly – why they love living surrounded by them provides invaluable insight.

This is without a doubt the most important place to start when it comes to talking about plant health, because above all else plants need light to survive. It is integral to the process of photosynthesis, in which plants create their own fuel by using light energy to convert carbon dioxide and water into glucose and oxygen.

A sunny windowsill will provide the most intense light and will be best suited to sun-worshipping cacti and succulents. Direct sun coming in through a window will generally be too intense for some indoor foliage, and so placement close to but not directly exposed to the rays is best. The further you get from a light source, the lower the quality and quantity the light gets. Plants sitting on the opposite side of the room to the light source with no direct view to the sky will generally be experiencing what we would consider low-light conditions.

Light will differ throughout the course of a day and as the seasons change. In winter and autumn, the sun sits lower in the sky and plants that were receiving adequate light in summer and spring can start to suffer. Be sure to stay on top of this changing light situation and adjust the position of plants throughout the year. You may need to shift certain plants closer to light sources or sit them higher up on furniture or plant stands during the cooler, darker months.

The absolute best way to test the moisture level of your plants is to simply dip your finger a few inches into the soil and feel how much has dried out. Do this every few days until you begin to understand its needs. Most (not all) tropical indoor plants like the first couple of centimetres of soil to have dried out before watering again. Always check the specific water requirements your plant needs, and then be sure to adjust them according to the seasons (less in winter when the soil is likely to dry out less quickly and plants tend to go through more dormant growing periods).

If you’re not feeling super confident about your moisture-sensing abilities, or have plants in awkward-to-reach places, a water meter will be your friend. Simply insert the prong into the soil and it will give you a clear reading of moisture levels, which you can then use to decide whether your plant is thirsty or not.

Indoor Jungle provides more details about soil, temperature, humidity and fertiliser, and ways to find your own plant style. We go room-by-room to see how plants can feature throughout the home and workspace in the most effective and practical ways, and profile 14 incredible plant-filled spaces from around the globe for endless plant inspiration.
