Orchid Blooming Tips - Provide More Water When Buds Are Swelling

Throughout the year, orchids need varying amounts of water for optimal growth. During their dormant period (usually winter), they need less water; during the growing and blooming seasons, they need more. The onset of the flowering season is signaled by nodules swelling on the stems or spikes. When you first see buds beginning to swell, this is your cue to provide more water to your orchids.

Adequate Water is Critical during Bud Formation

To produce flowers, orchids use a lot of energy and resources, especially water. This is because flowers are composed primarily of water, and the flowers and foliage release water vapor through transpiration. Transpiration is simply process by which water is lost when the plant opens its pores. Naturally, the plant has to compensate for lost water. Additionally, the orchid uses hydraulic pressure to force the buds to open into a flower. The cells of the buds must be filled with water to make them swell like an expanding balloon. Without adequate water, the water pressure will be too weak for the buds to open.

Under-watering and Bud Blasts

If you under-water your orchid during the critical stage of bud formation, your orchid will preserve moisture in the foliage, starving the buds of the water they need. This will cause the buds to shrivel up and fall off the plant. This condition, where the bud falls off before blooming, is known as a "bud blast." While there are other possible reasons for "bud blasts," under-watering is usually the cause.

Water with Lukewarm Water

Never use cold water when watering your orchid. Cold water can shock the roots and buds, and slow down its growth. A difference of 10 degrees Fahrenheit or more between the water and room temperatures may damage the cells of your plant. Ideally, the water should be lukewarm; the water should feel comfortable to touch, neither too hot nor too cold.
