Peace lilies are relatively low-maintenance plants known for their glossy green leaves and bright white spathes. The pretty houseplants thrive in bright light, well-draining soil and regular watering. However, various factors can cause poor growth. Insufficient light, poor soil drainage and nutrient deficiency can hinder peace lily flowering and overall growth.

If you've noticed your peace lily's growth has become stunted, Jo Lambell, a houseplant expert and the founder of Beards & Daisies, has shared one task that may "encourage new growth" on your peace lily. Jo, who has 10 years of experience running her business, is a trusted voice in the indoor plant industry. She claims that pruning peace lilies in spring and removing yellow leaves will "encourage new growth".

Jo said: "Spring is prime time for tidying up your houseplants.

"If you’ve got a peace lily, it’s a good idea to remove any dead or yellowing leaves to encourage new growth. This also helps keep the plant looking fresh."

The houseplant expert also recommended fertilising your peace lily in spring to boost them.

Fertilising your peace lily in spring

Peace lilies start re-growing again in spring, so now is the time to give them a good feed.

Jo recommends feeding most houseplants a balanced liquid fertiliser like 10-10-10 (NPK). These fertilisers contain equal parts nitrogen, phosphorus, and potassium, which are essential for plant growth.

The plant needs to be fed every few weeks. However, it's important to not overfeed them as it can burn the plants.

When to re-pot your peace lily

Peace lilies need to be repotted every one to two years when they start to outgrow their pots, and spring is the time to do it.

Jo added: "If you can see roots poking out of the drainage holes or if it’s just getting a little cramped in there, it’s time to move up to a bigger pot."
