It is best that a Purple Waffle Plant receives bright, indirect light. Keep your plant away from direct sunlight because it will lead to leaf burn. Your plant will appreciate being placed by a window that faces either east or west. This will help it get the bright and filtered light it requires throughout the day.

You can also use an artificial grow light to ensure your plant gets the right light. Put the grow light on top of the plant and expose them to that for around 12-14 hours a day. This will replicate the natural daylight.


Water your Purple Waffle Plant often, but do not overwater it. You should aim to water your plant once or twice a week. Never allow this plant to sit in standing water because it can cause the roots to rot. To help ensure this doesn't happen, provide your plant with a pot that has drainage holes. 


The pH level for your Purple Waffle Plants soil should range from 6.0 to 7.0. You can use a soil pH testing kit to ensure the level is suitable for your plant. Your plant can do well with organic matter (if you decide to take the organic approach). You can add organic matter to the soil mixture, which can benefit your plant's overall health. 


Temperatures between 65°F and 75°F (18°C to 24°C) are best during the day for your Purple Waffle Plant. Don't expose your plant to extreme temperature fluctuations (both heat and cold), as it is very sensitive to temperature changes. Always monitor your plant to ensure the range in temperature is suitable and make any adjustments if needed. 


Your Purple Waffle Plant will thrive best in moderate to high humidity. Try to keep humidity levels for this plant between 50% and 60%. This will help ensure that it grows its healthiest. To increase humidity levels, you can mist the leaves often. Do this by using a spray bottle and filling it with water. However, please don't overdo it, as this can cause fungal concerns for the plant.


Fertilize your Purple Waffle Plant with a balanced, water-soluble fertilizer that has an equal ratio of nitrogen (N), phosphorus (P), and potassium (K). Or a ratio around 10-10-10. Your plant should be fertilized every two to four weeks during the active season. Reduce fertilization in the fall and winter seasons.
