Arequipa erectocylindrica is a lesser-known yet fascinating cactus species native to Peru. This species distinguishes itself through its erect, cylindrical stems that can grow both solitarily and in clusters, reaching up to 50 cm in height. The green stems are densely covered with white areoles, from which emerge both radial and central spines, giving the plant a striking appearance. During the blooming season, Arequipa erectocylindrica produces beautiful, small, pink to red flowers that add a splash of color against the green backdrop of the stems.
Cultivation from Seeds:
-
Seed Preparation: The seeds of Arequipa erectocylindrica do not require any special treatment but soaking them in lukewarm water for a few hours before sowing can help improve germination rates.
-
Sowing: Use a well-draining cactus mix for sowing the seeds. Distribute the seeds evenly on the soil surface and lightly press them into the mix, ensuring they are not buried deeply as they need light to germinate.
-
Germination Environment: Keep the seed tray in a warm place with plenty of indirect light. A temperature range of 20-25°C (68-77°F) is ideal for germination. Covering the tray with a clear plastic lid or wrap can help maintain consistent humidity.
-
Watering: Water the seeds gently to keep the soil moist but not waterlogged. Good drainage is crucial to prevent the seeds from rotting.
-
Germination Time: Seeds should begin to germinate within 2-4 weeks, though some may take longer. Patience is key during this initial growth phase.
-
Seedling Care: Once the seedlings emerge, gradually acclimate them to the environment by removing the cover for short periods daily, increasing air circulation.
-
Transplanting: When the seedlings are large enough to handle and have developed a few true spines, carefully transplant them into individual pots with suitable well-draining soil.
-
Ongoing Care: Water sparingly, allowing the soil to dry completely between waterings. Provide bright, indirect light and protect the plants from extreme temperatures.
Cultivating Arequipa erectocylindrica from seeds is a rewarding endeavor for cactus enthusiasts, offering the chance to grow a unique and beautiful species that can enhance any cactus collection or garden with its elegant form and vibrant flowers.
