Peace lilies are beautiful houseplants, known for their glossy leaves and white flowers. They can be tricky to care for, leading to short flowering periods, especially during temperature changes. This can be incredibly annoying, especially because peace lilies should bloom for months at a time.
Deadhead Spent Flowers and Foliage
Experts from Blooming Backyard have shared top tips on getting one to re-flower. They said: "Your peace lily flower can last for up to a month and then will turn yellow or green before eventually turning black or brown. Deadhead your peace lily flower at any stage to preserve the beauty of this plant."
This includes removing any spent flowers and any foliage that has begun to turn brown and wilt.
Repot and Feed for Better Blooms
It can also be a good idea to repot the houseplant, especially if it is too small for its current home. The experts said a great growing medium can be made at home by combining two parts of potting soil, one part perlite and one part coconut coir.
When planting, take a look at the pot you're using, as peace lilies like to be slightly compressed into pots, with no roots popping out.
The experts said: "Nutrients are essential components in plant health, particularly if you want to encourage your plants to flower.
"Recently purchased peace lilies won't require feeding, but if they've been in the same pot for a while and have used up all the available nutrients, fertiliser or repotting is the only way to perk them up again."
It's recommended to use a balanced fertiliser and to feed them at least once every two months. For peace lily owners who notice more green foliage, reduce feeding to every three months, or slightly reduce the strength of the food.
This may not help heading into the autumn and winter months, but there will be an improvement come spring.
Watch for Nutrient Deficiency and Watering
Weak flowers are also a sign of nutrient deficiency, according to the gardening experts. If they are weak or not well-formed, switch to a feed which is high in phosphorus. The experts said: "This nutrient encourages flowering and fruiting in plants and should spur flowering in your peace lily too."
Other ways to boost flowering include keeping it in a warm environment and avoiding any sudden temperature changes. It's also a good idea to keep the watering steady and ensure that the houseplant isn't sitting in water.
Peace lilies are susceptible to root rot just like orchids, so it's crucial to keep the soil moist but not too wet.
