Cut the orchid’s flower spike halfway down after the last bloom has fallen with a clean, sharp razorblade. Using a dirty or dull cutting implement can cause damage or infection to your Vanda orchid, preventing rebloom.
Take a pinch of ground cinnamon and apply it to the cut end of the flower spike. This will prevent the stem from becoming infected and harming your Vanda orchid. Alternatively, you can seal the cut end with a small amount of melted candle wax.
Continue to care for your Vanda orchid as normal until it blooms again. This should take between one and three months. The Vanda orchid’s new bloom should last between two and four months.
