Cactus, Ratchet

Transplanting:

• Repotting is typically needed every 2 to 3 years or when the plant outgrows its container.
• When repotting, handle with care, as the plant can have sharp spines.

Light Conditions:

Ratchet thrives in full sun to partial shade.

• Full Sun:
  It is best to position it where it receives ample sunlight, ideally at least 6 hours daily.
• Partial Shade:
  While it can tolerate intense sun, providing some afternoon shade during the hottest months can prevent potential scorching.
• Indoor Growing:
  If grown indoors, place it near a south-facing window to ensure sufficient light exposure.

Temperature and Humidity:

• Warm Temperatures:
  This cactus is well-adapted to the Caribbean's warm climate. It can tolerate temperatures ranging from 10°C to 35°C, thriving best between 21°C to 35°C. While it can withstand brief periods of cooler temperatures, prolonged exposure to cold should be avoided. In areas with occasional cold snaps, consider providing protection or moving potted plants indoors.
• Low to Moderate Humidity:
  Prefers low to moderate humidity levels (between 30% to 60%). It tolerates higher humidity (up to 80% to 85%) if paired with very well-draining soil and excellent air circulation. Avoid stagnation—use open spaces or shelves to keep air moving and prevent rot.

Soil:

• Planting in a well-draining soil mix is essential.
• Use a cactus or succulent mix, or amend regular potting soil with sand and perlite to enhance drainage.
• Mulch (such as grass clippings and wood chips) can be added to the surface of the soil to retain moisture and keep down weeds.

Watering Frequency:

• Ratchet is drought-tolerant and prefers infrequent watering.
• Allow the soil to dry out completely between waterings.
• During the growing season (spring and summer), water thoroughly but sparingly.
• In the cooler months, reduce watering frequency significantly, as the plant enters a dormant phase.
• Overwatering can lead to root rot, so it's crucial to ensure proper drainage.

Propagation:

There are two primary methods to propagate Ratchet, namely through pad cuttings and seeds:

• By Pad Cuttings (Vegetative Propagation):
  This is the most straightforward and commonly used method. Choose a mature, healthy pad (also known as a cladode) from the parent plant. Place the pad in a dry, shaded area for about 1 to 2 weeks to allow the cut end to form a callous. This step is crucial to prevent rot when planting. Once calloused, plant the pad upright in well-draining soil, burying it about 1 inch deep. Support the pad with rocks or stakes if necessary to keep it upright. Refrain from watering for the first month, as the pad contains sufficient moisture. After roots develop (typically within a month), water sparingly, allowing the soil to dry out completely between waterings.
• By Seeds:
  While more time-consuming, propagating from seeds allows for greater genetic diversity. Collect seeds from mature fruits of the Ratchet. Clean them thoroughly to remove any pulp. To enhance germination, lightly scarify the seeds by rubbing them with sandpaper. This helps water penetrate the hard seed coat. Soak the scarified seeds in water for 24 hours to further improve germination rates. Sow the seeds in a well-draining cactus mix, covering them lightly with soil. Keep the soil moist but not soggy. Place the containers in a warm, bright location. Germination can take several weeks to months, so patience is key.
