Adenia Venenata Care

Light: Place your Adenia Venenata where it gets bright but indirect sunlight. Avoid direct, harsh sunlight, especially during hot hours.

Soil: Opt for well-draining soil, such as cactus or succulent mix. You can enhance drainage by adding sand or perlite. Make sure the soil is slightly acidic to neutral.

Watering Frequency: Water more often (once every 1 to 2 weeks) during the growing season (spring and summer), but reduce watering in the dormant season (fall and winter).

Temperature: Keep your Adenia Venenata in a warm environment and shield it from cold drafts and frost.

Humidity: While it can tolerate lower humidity, providing some moisture can be beneficial. You can achieve this by misting the plant occasionally or placing a tray of water nearby.

Fertilizer: Feed your plant with a diluted liquid fertilizer every 4-6 weeks during the growing season. Reduce or stop fertilizing during the dormant season.

Adenia Venenata Growth

Typically, planters propagate through seedings. It can also be propagated through cuttings, but this plant doesn’t usually produce a caudex. Propagating through seeds will ensure that your Adenia Venenata will grow a caudex and be perfect for decoration. For your succulent to produce seeds, it is advisable to propagate through cuttings.

This succulent doesn’t also need regular pruning. Remove any dying or wilted leaves for your Adenia Venenata to remain beautiful and in shape. Pruning is helpful to maintain your succulent’s health. It is advisable to transplant your Adenia Venenata every two to three years only.

You may also observe your plant when the roots come from the drainage holes. It is most likely time for repotting. When repotting, adding a slow-release fertilizer to your plant is also an excellent opportunity. A good characteristic of Adenia Venenata is that it is resistant to pests. However, keep an eye out for your succulents to avoid overwatering.

Commonly asked questions about Adenia Glauca

In this section, I collects some popular problems that easily happen around this fascinating succulent. These questions are selected from planters who possess this Adenia, so maybe you can find yourself in it. Let’s get into the first thread:

A thread from Separate_Bend6719: My first time owning a Adenia Venenata. Since I got the plant (2 months ago) it was thriving & doubled in height under my grow light. But since I watered it ONCE (a month ago & I made sure soil was completely dry), I’ve noticed it stopped growing, and the leaves started to yellow and felt off from the bottom up. The rest of the leaves also looking droopy. Am I underwatering or overwatering? root rot or something else? That one time I watered deeply and the water came out of the drainage hole. The soil is also very dry rn but I am not sure if I should water again. Any help is appreciated!

Answer: Based on our experience, your succulent is suffering from underwatering. Firstly, if you water only once a month in the growing season, you put it in the situation that this Adenia has to use storage water, making it much drier. You said: ‘You let the soil completely dry’ that is totally correct, but you should water it more frequently (recommended 1-2 times/week). Besides, you can place it near the window for the leaves to get more light.
