Below are some of the requirements to grow Crassula perforata – String of Buttons.

Soil Requirements

Crassula perforata – String of buttons is a succulent plant that is why it has similar soil requirements. It needs the soil to be neutral to slightly acidic, well-draining, nutrient-rich, and porous. Soil should not trap any water inside it, because the roots of the String of Buttons are very delicate and can get damaged if the soil beneath it stores water. Such soil consists of fertilizers, sand, dirt, compost, pebbles, and perlite or pumice. These substances not only make it porous and well-draining but also provide it the required balance of nutrients that succulent plants need to grow. To boost its growth, you can add fertilizer after planting as well. Soil with the nutrient deficiency will not be able to support their growth and would restrict your plant’s height and spread.

Sunlight Requirements

The String of Button plant requires plenty of sunlight to grow and thrive, under low light conditions they can grow but will never reach their potential height or spread. Also, in low light, they will not bloom. Their light requirements are similar to most other succulent plants. If you are keeping them indoors, make sure to keep them somewhere bright. If you have a window that opens east, it would be the best place to keep them. You can also grow them outdoors, but make sure that they are not under the shade of your building or other plants. They need full sun to grow, under partial sunlight, their growth is restricted and limited. Sometimes, the String of Buttons also changes its color because of the light deficiency, if that happens, you must keep them in some bright place.

Temperature Requirements

The String of Buttons plant is capable of surviving the harshest weather in the desert areas, meaning that they can survive the hottest climates. But when they are planted in cold regions, they cannot survive if they are not protected from harsh cold or snowfall. According to USDA, it can survive in 9 to 12 zones. This means they can survive a temperature as low as 32 degrees Fahrenheit. In zones that are colder than this, it won’t survive the winter. But you can still grow them in these zones as well, but you will have to keep them indoors to protect them from snowfall and below zero temperatures.

Water Requirements

Regular fertilization helps maintain a sufficient amount of nutrients in the soil.


The String of Buttons plant grows very slowly but it outgrows the pots it is initially planted. When that happens, it is time to shift this plant into a bigger pot. Keeping a full-grown plant in a small pot would only restrict its further growth. To avoid this, it is better to replant it into a bigger pot. First, you will have to prepare a bigger pot using the required type of soil. Then uproot and transfer the old plant. After uprooting and transfer are complete, provide your plant some water. This water will help its roots settle quickly in the new soil.
