Finding light for Rockweed in your home

Rockweed 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 city to see how the current weather in your area affects the placement of Rockweed in your home 🏡.
How to fertilize Rockweed

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