How do you care for the Iron Bone (Tiegulan) series so that they bloom? A few practical tips to share

The Iron Bone series of orchids gets a strong reaction from netizens: the flowers are beautiful, but they are reluctant to bloom. There are tricks to getting them to flower: water, fertilizer, and sunlight. Specifically: control watering, and for a month before the hottest weather, keep up water restriction for several days at a time; apply a high-phosphorus fertilizer around the flowering season, preferably a fairly quick-acting one, but be careful about the amount; give plenty of sunlight. Iron Bone series varieties have well-developed root systems and thicker leaves, so they are generally harder to scorch or burn at the tips.
