How to fertilize Korean Hibiscus

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 Korean Hibiscus after it doubles in size or once a year—whichever comes first.

Korean Hibiscus is generally considered an easy-to-care-for plant and makes a great choice for beginners!
Water Needs

Sunlight Needs
Korean Hibiscus requires abundant, bright and direct light. Place it less than one foot from a window to ensure it receives enough light to survive 💪. Select your region to see how the current weather in your area affects the placement in your home 🏡.
Toxicity
Korean Hibiscus is not known to cause harm to humans or pets. Regardless, if you, a family member, a cat, or dog has ingested any plant material, please consult a doctor or a veterinarian.
Humidity
Korean Hibiscus doesn’t require additional humidity. Plants absorb most water through their root system rather than their leaves, so the best way to provide humidity for your plants is through watering the soil.
Soil
Korean Hibiscus does best in well-draining soil. A good soil will contain lots of organic matter such as coco coir as well as perlite or vermiculite to help with drainage. Adding a handful of perlite to regular store-bought potting soil should do the trick!
Fertilizer
Korean Hibiscus should be repotted after it doubles in size or once a year, whichever comes first. Fresh potting soil has all the nutrients your plant needs, so as long as it’s refreshed yearly, you shouldn’t need to use fertilizer. Remember, plants get their energy from sunlight, not fertilizer!
Native Region
Korean Hibiscus is native to Worldwide.
Growth Pattern
Korean Hibiscus will branch off as it grows. To encourage branching, pinch off the newest growth at the tip and the stem will branch off into two.
