Why Is My Succulent Stretching and Getting Leggy?
The short answer
Tall, spindly, pale new growth with the rosette opening up and flattening means your succulent isn't getting enough light and is stretching toward it, a condition called etiolation. Rosette succulents open flat and put out long, bare stem between leaves in an effort to collect more light.
Move it to your brightest window or add a grow light, because succulents want roughly ten or more hours of bright light indoors. Be honest with yourself about one thing: the stretched, leggy part will not tighten back up, so to restore a compact shape you cut off the top, let it callus, and re-root it, using the leftover pieces to propagate. Some minor deformation from low light can be permanent.
Reading the signs
Etiolation is the plant's response to too little light. Iowa State Extension describes the signs as tall, spindly, lanky new growth that is pale in color, and notes that rosette-forming succulents often open up and flatten their leaves in an effort to collect more light. Long gaps of bare stem between leaves are the giveaway.
A succulent doing this isn't sick or short of water; it's light-starved. Feeding or watering it more won't help and can make things worse, because the real shortage is light.
The fix is light, but stretching doesn't reverse
Give it much more light. Succulents grown indoors want bright light for roughly ten or more hours a day; move the plant to your brightest window, or if no window is bright enough, use a high-output full-spectrum fluorescent or LED grow light set within about 12 inches of the plant on a timer for 12 to 16 hours a day.
Here's the honest part: better light greens up and compacts new growth, but it won't un-stretch the leggy stem that already formed, and Iowa State notes some low-light deformation can be permanent even after more light is provided. So expect the existing stretch to stay.
Restoring a compact shape
If you want the tidy, compact look back, cut off the stretched top with a clean knife, let the cut end dry and callus for a few days, then set it on or just into a gritty mix to re-root. The bare stem left behind will often push new offsets, and any leaves you removed can be laid on soil to propagate more plants.
Once everything is in brighter light, the new growth comes in tight and normal-sized. If you're not sure how much light your spot actually provides or which approach suits your particular succulent, your local Extension office or Master Gardener program can advise.

- Iowa State University Extension - Common Problems and Issues of Succulents — States that insufficient light causes etiolation (leggy growth) with tall, spindly, lanky new growth that is pale in color and rosette forms opening up and flattening to collect light; that indoor succulents need roughly ten or more hours of light a day and grow lights should be within about 12 inches for 12 to 16 hours; and that while some succulents recover with more light, others require cutting back to remove lanky growth and some low-light deformation is permanent.
- University of Maryland Extension - Lighting for Indoor Plants — States that insufficiently lit plants become spindly or leggy as they stretch to reach light and show fading leaf color, and that the same plant grown in brighter light would be more compact, better branched, and have normal-size leaves.
