Adenia Spinosa Care

Sunlight: Bright, indirect sunlight. However, it should be protected from direct, intense sunlight, which can scorch its leaves.

Temperature: It prefers temperatures between 70-85°F (21-29°C) during spring and summer and is protected from frost and extremely low temperatures.

Watering: Always allow the soil’s top inch (2.5 cm) to dry completely before watering. During the growing season, water more frequently (approximately once every 1-2 weeks). In contrast, reduce watering in the dormant season, providing water only sparingly to prevent the caudex from shriveling.

Soil: Well-draining succulent or cactus potting mix. You can enhance drainage by adding perlite or coarse sand to the mix.

Choose the Right Pot: Select a pot with drainage holes to prevent waterlogging. The pot size should accommodate the plant’s caudex and allow for growth.

Prune: Prune and shape your Adenia Spinosa as desired, but be cautious of the sharp spines on the caudex. Wear gloves when handling the plant to protect your hands from these spines.

Fertilization: Feed your succulent during the growing season with a balanced, diluted liquid succulent fertilizer every 4-6 weeks. Reduce or stop fertilization during the dormant season.

Adenia Spinosa Growth

This succulent can be propagated from both seeds and cuttings. Adenia Spinosa will produce a thick stem or caudex when propagated through seeds. When propagating through cuttings, wait a few days for your succulent to be calloused before replanting.

You may need to re-pot every 2 to 3 years or when the plant has already outgrown its current pot. When repotting, use fresh soil to avoid spreading diseases and infections. Ensure you carefully handle your plant when repotting or pruning since it is poisonous. You should wear gloves when touching your Spiny Greenstem.

Overall, Adenia Spinosa is resistant to pests. However, Watch for common succulent pests like mealybugs and aphids. Make sure to avoid overwatering to avoid any decay or infections. Be cautious when handling Adenia Spinosa’s spiny caudex to avoid injury.

Commonly asked questions about Adenia Spinosa

As a routine, I write this section to share with all Succulent City’s readers some common issues and how to deal with them. All the answers are both from my experience also from some that I find it can’t be better.

A thread from iam_rak1b: Help needed!! What’s wrong with my Adenia Spinosa? What should I do to make it leaf out?

Answer: I think your succulent is lacking sunlight. If I were you, you can try to place it near sunlight but not too intense to make your leaf out.

A thread from fluctuating_rating: Looking for advice: Adenia spinosa leaves isn’t coming out fully green. I’m happy that its caudex is fattening, but the leaves has never looked evergreen since acquisition last September 2021 (last pic).

Answer from pachypodiatrist: It seems like an iron deficiency. I have treated several of my plants (including various Adenia) and they very quickly gained color they didn’t have before. You don’t have to buy something specifically for plants – I just crushed up a dietary iron supplement in their water. It was very cheap and very effective.
