Introduction

As October unfolds, orchid enthusiasts brace themselves for the changing seasons. It's that time of year when Catasetinae orchids embark on their journey towards dormancy, and we're here to provide you with valuable insights on how to care for your orchids during this transitional period. This newsletter is packed with essential information to help you understand Catasetinae care, orchid dormancy, watering frequency, and more. Let's dive into the world of orchids and ensure your plants thrive during the colder months.

Catasetinae Care in the Changing Weather

The past year has witnessed a remarkable flowering season for Catasetinae orchids, and it's a testament to the dedication of growers across the country. However, with the arrival of October, it's time to prepare your beloved orchids for the impending dormancy phase.

Understanding Orchid Dormancy

Dormancy is a crucial phase in the life cycle of Catasetinae orchids. Some parts of the country are already witnessing the onset of dormancy as nature undergoes significant changes. Three key environmental factors trigger this phase: the rainy season drawing to a close, cooler nights and days, and shorter day lengths.

In response to these changes, it's essential to adapt your orchid care routine. Start by reducing the frequency of fertilization, as fewer nutrients are transported to the root system due to reduced rainfall. Additionally, allow your orchids to experience longer dry intervals by adjusting your irrigation schedule. This increasing dryness between waterings signals to the orchids that it's time to harden off their pseudobulbs, a vital step in preparing for the forthcoming 2-4 month winter dry period.

Maintaining Ideal Conditions

To ensure a successful dormancy period, focus on maintaining optimal conditions. Keep humidity levels in the range of 40-60%. While brief deviations from this range are acceptable, consistency is key. Adequate light and night temperatures of 55 degrees Fahrenheit or higher are essential.

Root Care and Repotting

During this period, it's best to avoid repotting your orchids. Their roots are well-established and disturbing them can lead to stress. If you've neglected repotting earlier, it's advisable to wait until the next spring.

Embracing Deciduous Nature

One of the remarkable attributes of Catasetinae orchids is their deciduous nature. If your orchid leaves suffered damage during the summer, fear not, as these leaves are on the verge of falling off. Come next spring, your orchid will sprout new foliage. Few orchids are as forgiving when it comes to leaf damage.

Blossoming Beauty

As we transition into fall and winter, it's a sight to behold in our greenhouses. Catasetums are putting on a dazzling display, Cycnoches are blooming with exuberance, and the Mormodes orchids are getting ready to spike. The excitement doesn't stop there; the blooming season for Clowesia rosea hybrids is just around the corner, starting in December and January.

Conclusion

With the changing seasons, orchid care evolves, and understanding the intricacies of Catasetinae orchids and their dormancy phase is crucial to their well-being. As you embark on this journey, remember to adjust your watering frequency, maintain proper humidity, and embrace the deciduous nature of these incredible plants. The forthcoming blooming season promises more captivating moments, making your orchid care efforts truly rewarding. Stay tuned for more updates and insights in our next newsletter, and may your orchids flourish in the months to come.
