Finding light for Sea Lettuce in your home
a window
Sea Lettuce 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.

How to fertilize Sea Lettuce
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 Sea Lettuce after it doubles in size or once a year—whichever comes first.

Hello, can anyone help me revive this plant? I recently acquired this plant, but it’s unfortunately dying. Initially, I had it in soil, but it wasn’t thriving, so I removed it and placed it in a vase. Despite these efforts, the plant’s condition hasn’t improved. My current living space doesn’t receive direct sunlight like my previous one, but I ensure that the blinds are open to allow some natural light in. Additionally, I purchased a LED plant light, but it didn’t seem to be effective either. #

This is classified as sea lettuce, but I don’t think that’s the proper classification for this type of cactus. Does anyone have an idea what this is? I can’t identify it through the app.  #GreenLaver
