Use these instructions to care for a Croton Petra indoor plant. This guide will tell you how to water a Croton Petra; its light, temperature, and humidity preferences; and any additional care it might need to help it grow.
Your Croton Petra will do best in a bright spot, as it needs lots of light (if possible 4-6 hrs. Per day) to produce all those colorful leaves! If your croton does not get enough light, you might find the plant grows tall and lanky with spare leaves lacking the rich, dark hues.
When the soil begins to dry out, water the plant thoroughly until the water flows out the bottom of the container. They are not as thirsty as other indoor plants, but will drop leaves if kept too dry. Take note—wilting for a Croton means too much water.
Crotons appreciate generous amount of humidity. You can boost the humidity by misting the leaves once a week or placing it in a well-lit bathroom.
This plant prefers temperatures between 60-70 degrees. Keep your Croton Petra away from drafts and cold areas like a windowpane in the winter.
For best results, use a general houseplant fertilizer once in early spring, once in early summer, and again in mid-summer. Do not feed in the fall or winter.
Don’t panic if your plant drops a few leaves upon arrival. Generally, the Croton Petra does not like to be moved, so a few falling leaves within a week doesn’t mean you are doing anything wrong. Make sure you follow the water and light guidelines and, with a little TLC, before you know it you will have fresh, tender leaves that will soon mature to their full, blazing glory!
Moderately toxic to pets and humans. Typically, ingestion will cause mouth and stomach irritation and possible vomiting.
