Dying Corkscrew Rush

1. Insufficient Light

Your corkscrew rush is a sun-loving plant. Hence, it is important to place it in the sunniest place in your room. The plant must require morning and evening sun. nonetheless, there is a certain time limit for that.

Because it will affect adversely if you keep your corkscrew under direct sunlight for hours after hours. Two to three hours of sunlight is enough for them to thrive jollily. Sunlight more than that will cause scorch and dehydration to the plant.

For your information, over-exposure to the sun can also bring negative results like the curling of leaves and brown edges. However, the Juncus can tolerate insufficient light to some extent. But, this way it will not grow much.

Then again, if you place the corkscrew rush in a dark location then you might discover expeditious leaf loss. And a plant losing its leaf immensely is not going to live for sure. Thus, ensuring the light is so much important especially if it is a corkscrew rush.

  • Semi-shaded conservatory places can decline to scorch the juncus plant as well. So, think of it as an option.

Ensuring a brighter environment for a certain period can result in a healthy plant. Since you have to take the plant at night temperature that is sometimes below 8 or 10 degrees Celsius so, light in the daytime is important.

2. Improper Watering

The water requirement in a corkscrew rush is quite different. Unlike other indoor or outdoor plants, Juncus Effusus Spiralis require soil that remains constantly wet. Only wet soil can confirm the best thriving of the plant.

It is simply because dry soil eventually kills the Corkscrew rush. It makes the leaves turn yellow and brown getting too dry. Where all other potted plants require small holes in the bottom surface of the pot for better drainage, Corkscrew requires no hole.

Hence, it requires immense water that will make the soil marsh and soggy. However, it is also important to ensure evenly moist soil. Moreover, under-watering the corkscrew plant will introduce you to crispy patches on leaves.

Nonetheless, keep in mind that over-watering the corkscrew plant also has side effects. It will create moldy soil that is responsible for the rotting of the roots and stems of the plant. So, in both aspects, you have to take proper steps.
