How to care for Black-Flag
Black-Flag needs 0.5 cups of water every 9 when it doesn’t get direct sunlight and is potted in a 5" pot.
Use our water calculator to personalize watering recommendations to your environment or download Greg for more advanced recommendations for all of your plants.
Black-Flag may have difficulty thriving, and will drop leaves 🍃, without ample sunlight.
Place it less than 3 feet from a south-facing window to maximize the potential for growth.
Select your region to see how the current weather in your area affects the placement of Black-Flag in your home 🏡.
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 Black-Flag after it doubles in size or once a year—whichever comes first.
