Crotons need bright light to look their best. Placing them within 3 feet of a window will keep them happiest. If placing them outdoors during the summer, acclimate them to full sun slowly over a few weeks. Full sun will keep their colors vibrant.
Even with bright light indoors, you may notice your Croton’s colors are a bit more muted. That is normal and they will brighten back up if you take them outdoors for the summer.
Crotons need a lot of water to keep their foliage hydrated. Checking the soil routinely will help monitor how often to water. Although they like frequent waterings, they do not like to be overwatered. When the top 50% of the soil is dry, or turns a paper-bag-brown-color, give it a drink and make sure to remove any excess water from below the pot.
It is best to use a liquid plant food high in nitrogen and potassium for your Croton to keep its vibrant colors. Feed your Crotons in early March, May, and July for best results. Avoiding feeding Crotons in fall and winter.
