Temperature Requirements
The ideal temperature range for the Conophytum obscurum subsp. sponsaliorum plant is between 60°F to 80°F (16°C to 27°C). It is crucial to keep the plant away from cold drafts and extreme heat sources. Temperatures below 50°F (10°C) or above 90°F (32°C) can be harmful to the plant and can cause irreversible damage.

Conophytum obscurum N.E.Br. subsp. sponsaliorum (S.A.Hammer) S.A.Hammer is a succulent, so it does not require frequent watering. Overwatering may cause the plant to rot and die. During the growing season, it is advisable to water the plant when the soil is dry. However, during the dormant season, the plant does not need water.
It is safe to reduce watering the plant when temperatures drop. C. obscurum subsp. sponsaliorum is a winter grower that requires generous watering from mid-autumn through late winter. The watering should reduce from late spring to late summer, as this is the plant's hot and dry season.
Fertilization
Fertilizer is not required for C. obscurum subsp. sponsaliorum to thrive. However, to enhance the plant's growth, it is good to apply a balanced, low-nitrogen fertilizer at the beginning of the growing season.
Pruning
C. obscurum subsp. sponsaliorum does not require pruning. However, in case of any damaged or diseased parts, it is advisable to remove them using sharp, clean shears.

Propagation of Conophytum obscurum N.E.Br. subsp. sponsaliorum (S.A.Hammer) S.A.Hammer
The Conophytum obscurum N.E.Br. subsp. sponsaliorum (S.A.Hammer) S.A.Hammer can be propagated through different methods.
Seeds
The most common method of propagating Conophytum obscurum N.E.Br. subsp. sponsaliorum (S.A.Hammer) S.A.Hammer is through seeds. The seeds can be sown in a well-draining sandy soil mix and placed in a warm and bright location. The ideal temperature for seed germination is between 18 and 24°C. The soil should be moist but not waterlogged, and the seeds should germinate in approximately 10 to 14 days. Once the seedlings have grown big enough, they can be transplanted into separate pots.
Leaf Cuttings
Another method of propagation is through leaf cuttings. Select healthy leaves and allow them to dry for a few days until the cut ends have formed a callus. Place the cuttings on a well-draining soil mix, and water sparingly. Over time, new roots and leaves will grow from the base of the cutting.
Offsets
Offsets or pups can also be used to propagate Conophytum obscurum N.E.Br. subsp. sponsaliorum (S.A.Hammer) S.A.Hammer. These are small plants that form at the base of the mother plant. The offsets can be carefully separated from the mother plant and planted into their own pots with a well-draining soil mix. They should be watered sparingly until they have established roots.
