About Otanthus
Otanthus is a super rare houseplant 🌿 that needs regular watering to thrive. They do best in long-lasting, direct light ☀️ and should be less than 1 foot from a window.
Otanthus likes soil that is well draining. Your plant shouldn't need added fertilizers if you repot each time it doubles in size.

How to fertilize Otanthus
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 Otanthus after it doubles in size or once a year—whichever comes first.
