Like other tropicals that call the tropical forest their home, Chinese evergreens like plenty of light, but they don’t deal well with being exposed to harsh sun.
First off, it’s important not to water on a schedule, instead keeping in mind that your Aglaonema likes its soil lightly moist. You can let the first inch or two of the soil dry out during summer, while during winter, it’s fine to let it go up to halfway dry before watering again.
You can plant your Chinese evergreen in a store-bought aroid soil mixture, but I’ll admit these can be a bit pricey. Luckily, it’s easy to mix a suitably chunky soil yourself.
Because Chinese evergreens are pretty good growers during the active spring and summer months, they do appreciate a bit of fertilizer from time to time.
As with similar tropical plants, one nice thing about Aglaonemas is that you don’t have to do much pruning on them at all. If a bottom leaf dies off, which is normal unless it happens at a worrying rate, you can leave it on the plant until it’s crispy.
