Quehlians Gymnocalycium Gymnocalycium quehlianum
ABOUT
The plant known as the chin cactus has a distinctive round and somewhat flattened shape, resembling a small green ball. Its surface is sectioned into multiple vertical ridges that radiate from the top to the bottom. Along the ridges, you’ll notice small areoles, which are like little patches of wool, from where sharp spines emerge. The spines can vary in color from white to a yellowish hue or even brown, and they form a sort of protective shield for the cactus. The number of spines in each areole and their arrangement can differ, sometimes appearing more like a starburst pattern. When it comes to flowers, the chin cactus produces attractive blooms that contrast beautifully with its green body. These flowers typically emerge from the top or near the top of the cactus. They can come in colors such as white, pink, or even soft yellow, adding a pop of color that stands out against the cactus's spiny background. Once the blooming season is over, the flowers may give way to small, round fruits. The combination of the cactus's spiny ridges, woolly areoles, sharp spines, and striking flowers give it a distinctive and appealing appearance, making it a favorite among cactus enthusiasts.

WaterThe common name for Gymnocalycium quehlianum is Spider Cactus. It is best to water this cactus thoroughly until water runs out of the drainage holes, and then allow the top inch of soil to dry out completely before watering again. This means you might water it every one to two weeks, but frequency can vary with temperature and humidity. Ensure that the pot has good drainage to avoid waterlogging. Approximately 8 ounces of water may be needed at each watering, although the amount can change depending on the pot size and environmental conditions.
LightSpider Cactus thrives in bright, indirect light—direct sunlight can be harmful, especially during the hottest parts of the day. The ideal spot for the Spider Cactus would be a south or east-facing windowsill where it receives light most of the day without the harsh midday sun. Some direct morning or late afternoon sun is beneficial, but ensure it's shaded during peak sunlight hours.
TemperatureThe Spider Cactus prefers temperatures between 50 and 80 degrees Fahrenheit. It can tolerate a minimum temperature of around 40 degrees Fahrenheit but shouldn't be exposed to frost. This cactus is best kept in a room where the temperature is consistent and away from drafts or heat sources that could cause sudden temperature fluctuations.
PruningPruning is generally not necessary for the Spider Cactus unless you need to remove damaged or diseased parts. If required, pruning should be done in the spring or summer, using sterilized and sharp tools. It's a good practice to wear gloves to protect your hands from the spines when handling the plant for pruning.
CleaningAs needed

Life cycleGymnocalycium quehlianum, commonly known as Quehl's Gymnocalycium, begins its life as a seed, typically requiring a warm temperature to germinate within soil with good drainage. After germination, a small cactus seedling emerges, beginning a slow growth process where it starts to form its spherical to cylindrical shape. As the plant matures, it develops characteristic ribbed stems with areoles from which spines and flowers will eventually grow. During its blooming phase, which occurs sporadically from late spring to early summer, it produces flowers near the crown of the stem, with colors ranging from white to pink. After pollination, typically by insects, it produces small, fleshy fruits containing seeds that, when dispersed, can give rise to new plants. Over the years, with proper care and conditions, Quehl's Gymnocalycium can reach its full size, continuing to produce flowers seasonally while being a long-lived cactus.
PropogationPropogation time
Spring-Early Summer
The most popular method for propagating Gymnocalycium quehlianum, commonly known as the Spider Cactus, is by seeds. Propagation by seeds is typically done in the spring or early summer when temperatures are warm, which facilitates germination. To propagate by seeds, one should sow the seeds in a well-draining soil mix, lightly covering them with a fine layer of sand or soil. The container with the seeds should be kept moist and placed in a warm, bright location without direct sunlight, as intense sun can impair germination. It can take anywhere from a few days to several weeks for the seeds to germinate, and during this time the soil should not be allowed to dry out completely. Seedlings are usually repotted once they have grown large enough to handle, usually one to two years after germination.
