🐶 🐈 👶 Toxicity

Sweet William is not safe to consume. If you, a family member, or a pet has ingested any amount of plant material contact Poison Control, US (800) 222-1222, or your veterinarian. If you have children, cats, or dogs in the home, we suggest keeping this plant out of reach.


💨 Humidity

Sweet William 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

Sweet William 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

Sweet William grows very slowly and doesn’t require added fertilizer. Replacing your plant’s potting soil once a year should provide them with more than enough nutrition. Remember, plants get their energy from sunlight, not fertilizer!

🌱 Propagation

Sweet William can be propagated by division into new individual plants.

  • Check to see if there is more than one plant. In some cases they may still be beneath the soil surface. If you feel confident, you may remove the soil to check for baby plantlets below!
  • If there are multiple plants growing, unpot the plant and gently tug the plants apart, being careful not to disturb too many of the roots. They may be connected by large root segments which you may need to break to free the plantlet.
  • Pot up the new plant in well-draining soil
  • Repot the parent plant back into its original pot

🧐 Troubleshooting

When troubleshooting a sad-looking houseplant, start by checking for signs of distress in its leaves, such as yellowing, browning, or drooping, which can indicate overwatering or nutrient deficiencies.

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

Ensure the plant is getting the right amount of light, as too much or too little can stress it.

Finally, consider environmental factors like temperature and humidity, and adjust care routines accordingly to revive your plant.
