Why Should I Repot My Prayer Plant?

I've grown stromanthe, or the payer plant, for years in my house in Ireland. In the video above, I share with you how to repot the prayer plant. Many of us have one with browning leaves stashed away in some neglected corner of the house. Most house plants like to be repotted every two to three years in spring, and the prayer plant is no exception.

I'm going to show you how to give this plant a new lease of life in six easy steps.

Repot your prayer plant every two to three years to keep it beautiful and happy.

Step-By-Step Instructions for Repotting a Prayer Plant

Before starting your repot, give the plant a good watering a couple of hours beforehand. This will help reduce the likelihood of transplant shock.

Step 1: Choose the Correct Pot

A plastic pot is the best choice for a moisture-loving plant like stromanthe, and I choose a pot just one size bigger. Don't be tempted to use a much larger pot. That's the quickest way to rot it off. You'll also want to choose a plastic pot that's deep enough to accommodate long roots and one with plenty of drainage holes.

Step 2: Mix the Soil

For prayer plants, light, well-drained soil is needed. I mix my potting compost with about 40% perlite. Perlite makes the soil fluffy and increases the water-holding capacity, and also increases air circulation. For moisture-loving plants like stromanthe, perlite is the perfect choice for aerating your mix and helping combat the rotting effect of overwatering.

Step 3: Remove the Plant

Remove the plant from its outer pot, and you'll be able to see if the roots have outgrown the space. Normally, I prefer not to interfere with house plant roots, but in some cases, there is no choice. Sometimes, you'll have to cut off the roots that have grown through the drainage holes to get the plant out of the pot. Squeeze gently on the sides and pull it out.

Step 4: Inspect the Roots

Time for a close inspection of the roots. Although stromanthe likes moisture, root rot is a common complaint. If your roots have a yellow tinge, then they're healthy. But if they're brown and mushy, action must be taken immediately, and you need to cut out any rotting portions. If the roots look okay, no cutting needs to be done.

Step 5: Move the Plant to the New Pot

Place a little of the mix at the bottom of the new pot and position your plant on top. Backfill the sides of the plant with the potting mix. Periodically bang the pot on the table surface to allow the compost to fill the air pockets between the roots and the soil.

Step 6: Remove Any Brown Leaves

The final step is to tidy up the plant by snipping off any brown leaves and then watering it well.

Your plant will take a few weeks to adjust after repotting but should then go on to reward you with plenty of pretty, tricolour leaves. Happy growing!
