How to Make a Vanilla Orchid Plant Bloom

Vanilla orchids are made to bloom, so if yours isn't blooming, something may be wrong. These tropical plants have extremely specific water, fertilizer, sunlight, temperature, and humidity preferences. They won't bloom without them. Make the changes to the location of the plant, the feeding schedule or the environment to closely match what the plant needs, and beautiful green, blue, or white plants will be your reward.

Unfortunately, vanilla orchids cannot bloom until they are three years old. If yours is younger than three, it will not bloom and cannot be rushed.

Look at the color of the orchid's leaves.
- If they are dark green, that means they are getting too much sun exposure. Move the plant to a less sunny area.
- If the leaves are yellow or even a brown color, this means that there is not enough sun exposure. Try moving it to a sunnier spot, such as a window ledge.
- If the leaves are a light green, that means there is a perfect amount of sunlight reaching it. The incorrect amount of sunlight can inhibit the blooming.

Measure the humidity of the air surrounding the plant using a humidity meter. Vanilla orchids require fifty percent humidity in order to bloom.
- If the air seems too dry, try placing the plant on a tray and fill the tray with water so that the air fills with humidity as the water evaporates. Top off the tray as often as needed, to ensure the tray has standing water in it at all times.
Orchids require a temperature of 70 °F (21 °C) during the day but allow a ten degree drop in the evening in order to bloom properly. Set your indoor temperature controls to make sure the temperature is set just right for proper blooming of your orchid plant.
This plays a huge role in the proper blooming of Vanilla orchids.
Cut back on fertilization every six months when the orchid grows more slowly. Under-fertilization will result in no blooming at all or just a few small blooms.

Question
How long does it take to get a vanilla bean>
Jacob Forbes
Community Answer
You need to allow approximately 3-4 years after planting 8 nodes of a vanilla cutting before a flower will appear. The flower must be hand pollinated, usually by midday on the day that the flower appears (the flower last for only a few hours). The bean that results from that pollinated flower will mature in 9 months. The curing process takes 3-4 weeks, and then the bean is ready for use.

Question
What do I do if my orchid has many flowers, but I am not getting any beans?
Harvey
Community Answer
This means that it is not being pollinated. Hand-pollinate the flower by using a toothpick or chopstick to gently brush together the male and female parts of the flower (the only natural pollinator of the vanilla orchid is a single bee species endemic to Mexico). The beans will mature in about 8-9 months, turning slightly yellow at one end.

Question
What fertilizer is needed for my vanilla orchid plant?
Community Answer
Many fertilizers may be used. A 20-20-20 fertilizer is fine; a fertilizer with nitrate nitrogen would be best, but not required. I would suggest the "weakly weekly" option when it comes to watering any orchid, accompanied by a monthly watering with no fertilizer (a flush). Use 1/5 to 1/4 the recommend amount through the growing season (late spring - early fall). Reduce the fertilizing frequency down to once a month or not at all through winter. If you're in the tropics, you may be able to fertilize year-round.
