Peace Lily (Spathiphyllum) | Plant Care Guide - Perth's best indoor plants

Peace Lily | Green Assembly

On NASA’s Top Ten Household Air Cleaning Plants list and one of the easiest plants to care for, the peace lily (Spathiphyllum) is one of our all-time faves. She will give you those white flowers if given enough light but if you’re like us and prefer just that deep green look simply snip them off!

The peace lily is one of the most popular plants to gift for celebratory occasions and is also often given as sympathy or condolence gift. And if you are buying a houseplant for yourself, we often recommend the peace lily is a great starting point to improve your green thumb.

Difficulty Level – Easy


The peace lily will tolerate low light but will grow faster in medium light. Direct sunlight, however, will fry its delicate leaves. If you have a hallway or darker room, then this guy is a great one for adding some greenery to dark spaces. However, if you want it to produce flowers each spring and summer it will need bright, indirect sunlight.


Allow the top of the soil to dry out about two inches between waters or simply wait for her leaves to droop. Cut back watering in the cooler months to give the plant a chance to rest and go semi-dormant. And don’t leave you spathiphyllum sitting with water in the drip tray, this is the fastest way to kill any plant!

All Green Assembly plants come potted with good quality soil but we have noticed that there is a lot of peace lilies around Perth that come potted in poor soil that stops holding water within weeks. If your spathiphyllum is constantly dry, the water drains straight through the bottom and the leaves are going yellow, it likely needs some better soil and repotting, then a good drink.


Feed your peace lily with a slow-release fertiliser once every six months following the instructions on the packet (remember, when you receive a plant from Green Assembly, it has enough slow-release fertiliser to last the first six months). We love Troforte slow-release for the miracle-working growth magic it seems to cast on all our indoor plants. During the warmer months, your peace lily likes a drink of the stinky liquid fish stuff (like Seasol) bi-monthly, again be sure to follow the dilution instructions on the packet before you add this otherwise the foliage can burn.

When if you start to see roots coming out the base of the pot (through the drainage hole) of your peace lily, it’s time to upsize and give him a slightly bigger home (a pot about 2 to 3 inches bigger).

Watch out! This guy is toxic to pets and mini me’s if eaten.


Use a soil moisture metre (AKA the handiest indoor plant tool ever invented) to check the soil of any plant before you water. That way you don’t get your hands dirty and you get an accurate reading of just how moist the soil is. PLUS our metres can be used for all your plants and you will never need a refill.
