Your Joseph's Coat is a brilliant spectacle of foliage, acting as a living, vibrant tapestry that constantly needs light to keep its rich colors on display.
The Prime Rule: Treat it like a sun-loving artist! Provide full sun (6+ hours of direct light) to achieve the deepest, most saturated reds, purples, and yellows. The colors are your light meter—fading hues mean it needs a brighter spot.
Indoors: Place it directly in the brightest available window.
The Warning: In low light, the plant will become "leggy" (stretched out) and its leaves will revert to duller green tones.
The Balancing Act: It craves warmth and consistent moisture, but absolutely despises "wet feet" (soggy soil).
The Rhythm: Water thoroughly when the top 1 inch of soil feels dry to the touch.
The Tell: If you forget, it will dramatically wilt—but don't panic! It usually springs back quickly after a good drink.
The Mission: To keep the tapestry tight and dense, you must be a frequent sculptor.
The Technique: Regularly pinch back or snip the growing tips of the stems. This forces the plant to branch out, resulting in a compact, bushy, and colorful mound.
Soil: Use a well-draining, organically rich potting mix.
Temperature: Keep it warm! It thrives in 65∘–$85^{\circ}$F (18∘–$29^{\circ}$C). It cannot survive frost.
Feeding: Fertilize once a month during the growing season (Spring to Summer) with a balanced liquid feed.
