Detailed care guide
Red Chinese evergreen is an air-purifying plant with beautiful leaves that blend red and green. It suits many indoor spaces and is easy to grow.
Watering
Water once the top layer of soil is completely dry. Overwatering can turn the leaves yellow and mushy, so be careful. Watering about once every 10 days is typical.
Light
It grows well even in low light, but does even better with bright indirect light. Insufficient light can cause the stems to grow leggy or the leaf color to fade.
Humidity
It prefers moderate to high humidity. In dry conditions, the leaf tips may dry out, so raise the humidity around it if your indoor air is very dry.
Temperature
It grows best at 18–27°C. Lower temperatures can slow growth and cause leaf problems.
A common first-timer mistake
Beginners often make the mistake of watering too often. Be sure to check that the top of the soil is dry before watering.
If you have pets
Red Chinese evergreen can cause mild symptoms like vomiting or diarrhea if pets eat it. Keep it out of reach where pets can't chew on it.
Seasonal Care
In spring and summer, growth is active, so fertilize once a month. Water regularly during this time, but watch out for overwatering. In fall and winter, growth slows, so it's best to cut back on both water and fertilizer.
Common Problems and Fixes
Yellow, mushy leaves can be a sign of overwatering. Water only after the top of the soil is dry, and use well-draining soil. If the leaf tips turn brown and dry, check whether the air is too dry; if the stems grow leggy from too little light, move it to a brighter spot.
Repotting and Propagation
Once the roots have filled the pot, repot using well-draining, breathable soil. If the soil has aged and airflow has worsened, repotting in spring or early summer is recommended. It's a good idea to trim any loose roots during repotting.
Who It's Good For
It's a great fit for anyone looking for an easy-to-grow indoor plant, or for first-time plant owners. Its air-purifying benefits also make it a good choice for offices, living rooms, bedrooms, and more. It's also recommended for anyone who wants to brighten up an indoor space with its colorful leaves.
