Soil Requirements

The String of Nickels plant is a succulent plant that grows in the tropical region, that is why its soil requirements are also slightly different from other succulent plants.

Low light can induce multiple growth problems and to avoid that we must keep them in full light conditions.

Temperature Requirements

The String of Nickels plant is native to the tropical region, this region is known for its hotness. The temperature in this region can be as high as 40 degrees centigrade during a hot summer day. This plant has multiple adaptations to this type of environment and can tackle the warmth easily but when it comes to cold environments. This plant would not survive out for long.

The optimum temperature for this plant’s growth is between 40- and 80-degrees F. (4 to 27 degrees C).

Water Requirements

The String of Nickels plant is a succulent plant and has similar watering needs, but it is more capable of surviving overwatering as compared to many other succulents.

  • You should also consider the seasons as well. During the summer, your plant would need more water and more frequently. While in the winter it would need less water and less frequently.
  • You should also consider the environment in which you are growing your plant. For example, if you are living in a hot area, the watering need of your plant would be different from the one that is being grown in a cold region. That is why you should prepare a watering chart according to it as well.
  • To check the moisture in the soil, you should check if the first layer of the soil is dry, which means you should water your plant, but if the soil is not dry, you should not water your plant and let the soil dry for one or two more days.
