Sundews are referred to as “flypaper” plants because the sticky hairs that cover their leaves capture insects and other animals. They are members of one of the most numerous families of carnivorous plants. Their leaves are covered in long tentacles, each of which ends in a gland that secretes a sticky substance.

Because of how these droplets appear when exposed to light, they are known as “dewdrops.” These glands produce nectar, which is used to lure prey, a potent adhesive, which is used to catch prey, and enzymes, which are used to break down food. When an insect is caught, neighboring tentacles will wrap themselves around it and suffocate it until it dies.

These plants rely on insects for their nutrition. In the ecosystem that sundews choose to live in, there is a high population of mosquitoes, which means that mosquitoes likely make up a major amount of their food there. Sundews may kill an insect that has been caught within approximately 15 minutes, although the digestion process might take many weeks.

Reasons for sundews turning yellow? 

Insufficiency of Light 

The lowest leaves of the plant will quickly turn yellow and perish if there is insufficient light combined with excessive waterlogging. Yellowing that does not go away and almost no leaves should only be present in the wintertime. This should be the case even if this is a natural process that occurs when a plant ages on a smaller scale. In the event that this is the situation during the hottest part of the summer, quick action is required. 

Put the plant in an area that gets just a moderate amount of direct sunlight outside of peak hours, or move it outdoors if that’s feasible. Even though it may be many weeks before the plant begins to recover, improving its growth environment and allowing for the presence of the odd bug will have a big positive impact on the plant’s overall health. After a few weeks have passed, the quantity of time spent in direct sunshine should be increased by two hours. 

We suggest providing your Sundew with a minimum of three hours of sunshine every day in order to offer the required nutrients for dependable development. A sunburn or the use of potting mix without carnivorous organisms are two other potential reasons for Sundews turning yellow. 

It is imperative that sundews not be repotted into any other compost, since the chemicals in such composts can swiftly cause root burn and eventually result in the plant’s demise.


Another significant challenge that you need to keep in mind is the yellow tincture of sundew carnivorous that is created by dampness.

When the weather starts to turn chilly, some individuals make the decision to bring their sundew plants inside. This is particularly common in regions where the temperature may drop below zero degrees outdoors.

Sundew plants are susceptible to having their leaves become a yellowish color when they are subjected to rapid shifts in humidity, temperature, and light. In addition to giving the plant a yellowish hue, it also causes the leaves to develop a few red spots here and there.

The plants get stressed when there is too little humidity, too heated temperatures, or too much or too little light, and this stress may lead not only to a yellowing or tingeing of the leaves but also to the plant’s irreversible harm or even death.

Lack of Protein and Nutrition

When it comes to extracting nitrogen from its traps, a carnivorous sundew plant would rather have protein than chitin. The same reasons why mammals need nutrients are why sundews require them as well. They need them in order to germinate, develop, defend themselves against diseases and pests, and reproduce successfully. Similar to mammals, plants need bigger, smaller, and even minimal quantities of nutrients in order to maintain good health.

Insects are the primary source of nutrition for sundews. The leaves of sundews will begin to turn yellow when they are not provided with sufficient nourishment to meet their requirements. Therefore, it is up to you to ensure that they consume enough amount of proteins and minerals.
