Anthurium blooms often last for months at a time, and it can be disheartening when they eventually fade away. But don't fret, it is possible to encourage your anthurium to rebloom – and we've asked experts how best to achieve this.
What causes an anthurium to stop blooming?
There are a few reasons your anthurium might have stopped blooming. They go through a natural flowering cycle and the spathes will die after several months. However, if you notice that the spathes aren't returning, it may be an indication that your plant has improper growing conditions.
'Unsuitable watering, improper lighting and infrequent repotting can cause an anthurium to stop blooming,' says Nastya Vasylchyshyna, botany expert at Plantum.
It's important to provide your anthurium with lots of bright, indirect light, and you should allow it to dry around 50% before watering again. Failing to do so could hinder the health of your plant and prevent new spathes from growing.
'Insufficient nutrition, brought on by a lack of regular feeding and depleted substrates, tends to be the most common factor,' says Nastya.
Anthuriums appreciate a balanced fertilizer, like this liquid plant food from Garden Goods Direct, to keep their modified foliage bright and thriving. However, take care not to fertilize anthurium too much as it could cause a build-up of excess salt.

How do you get an anthurium to bloom again?
The first thing you need to do to get your anthurium to produce its beautiful spathes again is assess its growing conditions.
'Anthuriums require bright, indirect light to bloom again. Avoid direct light, as that will lead to sunburned foliage and flowers,' says Julie Bawden Davis, indoor plant expert at Healthy Houseplants.
'You should also fertilize from spring to fall with a fertilizer high in phosphorus, which will promote blooming. Fertilize with a half-strength solution, as anthuriums can be damaged by too much fertilizer,' Julie adds.
You should always take care to water houseplants correctly if you want to encourage new growth.
'Tie your watering to the rate at which the top layer of the potting mix dries off – both letting the substrate dry out completely and watering it to the point of sogginess will be stressful to the plant,' says Natsya.
Using a planter with drainage holes, like these planters from Amazon, can help to collect and remove excess water from your anthurium. You can likewise use a well-draining potting mix for your anthurium to reduce the risk of waterlogged soil.
Julie notes you should also repot your anthurium regularly. 'Pot up anthuriums on a regular basis, as crowded roots can slow down or stop flowering,' she says.
'Anthuriums thrive in high humidity. You can boost it by either misting the plant regularly or placing a humidifier by the pot. Use lukewarm, settled, soft water for both watering and misting,' says Natsya. You can increase humidity for houseplants in several ways, such as using this mister from Amazon or this humidifier from Amazon.
'During the active growing period, the optimal temperature range for your anthurium will be 70–81°F. Protect it from cold drafts and don’t place it next to any heaters or AC,' says Nastya. 'Providing anthuriums with a period of rest will increase the chances of it blooming again. As soon as the plant finishes flowering, start lowering the growing temperature by 9–13°F each day to a minimum of 61–63°F ,' she adds.
