Nipple beehive cactus (Coryphantha macromeris)
Also known as: Big Tube Cory Cactus, Long-tubercled Cory Cactus
The Coryphantha macromeris cactus has a unique look, often compared to a large, irregular beehive adorned with tubercles. Each tubercle, or "nipple," is topped with a rosette of curved spines. This cactus, sometimes called the "nipple beehive cactus," stands out due to its distinctive structure. Despite its desert origins, Coryphantha macromeris exhibits notable cold tolerance, surviving temperatures as low as 20°F (-6°C) for brief periods.

What Is the Ideal Temperature Range for Nipple beehive cactus?
Coryphantha macromeris thrives best within a temperature range of 70°F to 85°F. This range supports optimal physiological processes like photosynthesis and respiration, ensuring robust growth and health. During this range, the plant is less likely to experience stress, promoting better growth and flowering.
What Soil is Best for Nipple beehive cactus?
Coryphantha macromeris requires soil that drains quickly to prevent root rot. Sandy soil, which allows water to pass through easily, is ideal. This characteristic ensures that the plant's roots remain healthy and can absorb nutrients efficiently, promoting strong growth and vibrant appearance. Incorporating loam into the soil mix helps provide essential nutrients. Loam is rich in organic matter, offering a balanced supply of minerals necessary for Coryphantha macromeris to thrive. This nutrient richness supports the plant’s developmental processes and strengthens its resistance against pests and diseases. This species benefits from a slightly calcareous soil, which contains calcium carbonate. The calcium content in the soil helps to maintain the plant's structural integrity and supports cell wall development, crucial for sustaining its overall health and robustness.
How to Fertilize Nipple beehive cactus?
For Coryphantha macromeris, a balanced, water-soluble cactus fertilizer diluted to half strength is ideal. Use approximately one tablespoon per gallon of water. Make sure the soil is slightly damp before applying liquid fertilizer to prevent root burn.
How to Prune Nipple beehive cactus?
When removing stems or dead parts, make clean cuts at the base of the plant. Avoid leaving stubs, as they can become entry points for pests or diseases. While removing damaged or dead parts is beneficial, avoid over-pruning. Excessive removal of healthy growth can stress the plant and hinder its natural development.
How to Propagate Nipple beehive cactus plant?
1
Collect seeds from ripe plants and clean them thoroughly to remove pulp residues. Soak the seeds in warm water for 24 hours to soften the tough seed coat, enhancing the germination rate when planted.
2
Prepare a well-draining sandy or cactus mix. Fill the seedling tray with this mix, placing seeds on the surface. Cover lightly with sand or perlite, ensuring they are not buried deep, as light exposure favors germination.
3
Select a healthy rootstock and prepare a matched scion from Coryphantha macromeris. Cut both with a sharp, sterilized knife, align, and secure them using grafting tape or rubber bands. Maintain humidity by covering with a plastic bag.
How to Repot Nipple beehive cactus plant?
1
Coryphantha macromeris signals its need for repotting when the roots begin to overflow from the drainage holes or when growth appears stunted despite proper care. Observing crowded roots or dull, slow development frequently indicates it's time to consider a new pot!
2
Opt for a pot slightly larger in diameter than its current one, preferably made of breathable materials like terracotta. This choice ensures proper drainage and airflow, which are essential for preventing root rot and promoting healthy root growth in this cactus species.
3
Selecting a well-draining cactus-specific soil mix is crucial. This type of soil provides the right balance of moisture retention and aeration, fostering an ideal environment that keeps the roots healthy and prevents overwatering issues.
