How to fertilize Corn Toadflax

Most potting soils come with ample nutrients which plants use to produce new growth.

To replenish this plant's nutrients, repot your Corn Toadflax after it doubles in size or once a year—whichever comes first.
Corn Toadflax is generally considered an easy-to-care-for plant and makes a great choice for beginners!

Greg does not have confirmed data on this plant’s toxicity. If you, a family member, or a pet consumes plant material of unknown toxicity, it’s always best to consult a medical professional.

🪴 Soil
Corn Toadflax 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
Corn Toadflax 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!

Inspect the soil moisture; too dry or too wet soil can cause problems.
