How to care for Ricinus
Ricinus needs 0.5 cups of water every 9 when it doesn’t get direct sunlight and is potted in a 5" pot.

Ricinus love being close to bright, sunny windows 😎.
Place it less than 1ft from a south-facing window to maximize the potential for growth.
Ricinus does not tolerate low-light 🚫.
Select your region to see how the current weather in your area affects the placement of Ricinus in your home 🏡.
Most potting soils come with ample nutrients which plants use to produce new growth.
By the time your plant has depleted the nutrients in its soil it’s likely grown enough to need a larger pot anyway.
To replenish this plant's nutrients, repot your Ricinus after it doubles in size or once a year—whichever comes first.
