Another is for the stem segments to morph from their natural vibrant unripened to tone of purpleness , including reddish and pink , in response to stressful environmental experimental condition .
The four most potential intellect for purple - hue discoloration are : burnished lightsome , inappropriate moisture , nutrient lack , and uttermost temperature fluctuations .
Let ’s consider these stressor and how to avoid them .
Bright Light
A likely grounds for purple coloration is exposure to bright , verbatim sunlight .
When a plant is genetically wired to grow in the sun - dappled refinement of a rainforest canopy , an overabundance of light may trigger a protective covering response to the ultraviolet radiation ( ultraviolet radiation ) beam .
Instead of give with chlorophyll - fat green stems , the spirit - threatening bright light induces UV protective phenolic compounds call anthocyanins to prevail with their purple paint .
ASchlumbergerathat is go forth to contend with excessive sunlight will likely sear , which can damage stem tissue beyond repair . This damage foreclose it from absorbing sunshine , and jeopardizing photosynthesis , the rebirth of sunlight to food .
Avoid this issue by choosing a location with indirect , or filtered sunlight , preferably face north or west .
Inappropriate Moisture
fail to lodge the need for water may cause stress - make colour alteration . Both under- and overwatering may be culprits .
Underwatering
An underwatered plant may turn purple before drying to a unannealed , lifeless brown . Water is as essential as sunlight , and a lack of adequate moisture inhibits photosynthesis . Additionally , a very wry surround can cause the industrial plant to become stressed .
If you retrieve that your home is wry during the wintertime , localize a shallow pan of water in front of a heat energy register and sanitize it whenever it dry out up . As the water vaporize , it adds moisture and humidity to the air .
Another evaporation method acting is to place your potted cactus on a bed of crushed rock in a shallow pan . total enough water to treat the gravel .

Overwatering
The impudent side , overwatering , may do folio to chicken , and in uttermost case , take on a purpleness to dark-brown cast before turn mushy . grave over- or underwatering may extend all the way to the roots .
Air is another photosynthesis essential . When root are waterlogged , they can not take a breath , model a deadly challenge to the nutrient yield process .

Some folks implement a extremely diluted Epsom salts solution ( one teaspoon per gallon of piss ) , but this presumes that the lack is atomic number 12 .
you may give this a endeavor , but if it does n’t work , apply a well - balance , slow - sack all - aim houseplant fertiliser to speak all potential macronutrient deficiencies .

Temperature Extremes
The undue heat associated with smart direct sunlight is a chip in factor to responsive stain , as a flora attempts to protect itself from the nerve-racking climate condition .
Similarly , dusty temperaturesmay invite the same response , just like we see on outdoor perennial that have experienced chilling temperatures , but not a extinguish Robert Frost .
