Watering
Water when dry. Once a week in the warmer months & every 2-3 weeks when winter comes around. The watering schedule will vary for you depending on your home environment, type of soil mix, and pot size.
Temperature
If your home is comfortable for you, it’ll be so for your houseplants too. Just be sure to keep your Aglaonemas away from any cold drafts as well as air conditioning or heating vents.
Humidity
Chinese Evergreens are native to the subtropical & tropical regions. Despite this, they seem fairly adaptable & do just fine in our homes which tend to have dry air. Here in hot dry Tucson, mine only have a few teeny, tiny brown tips.
If you think yours look stressed due to lack of humidity, fill the saucer with pebbles & water. Put the plant on the pebbles but make sure the drain holes &/or the bottom of the pot aren’t submerged in water. Misting a few times a week should help out too.
Fertilizing
Ags aren’t needy when it comes to fertilizing. I don’t fertilize mine but that might change soon because I’m experimenting with a concoction. I’ll let you know. Right now I give my houseplants a light application of worm compost with a light layer of compost over that every spring.
Soil
You want to use a potting soil that is peat-based and formulated for indoor plants. I alternate between Happy Frog and Ocean Forest. They’re high quality & have lots of good stuff in them.
Aglaonemas, like other houseplants, don’t like a heavy mix. You can up the ante on the aeration and drainage factors, which lessens the chance of rot, by adding some pumice or perlite.
Repotting / Transplanting
This is best done in spring or summer – early fall is fine if you’re in a warm climate. The faster your plant is growing, the sooner it’ll need repotting.
