What to Do When Orchid Flower Buds Turn Yellow


Yellow orchid flower buds are typically a sign of bud blast, which is a term used to describe flowers that have prematurely aborted. In a lot of cases, the yellow buds will also be accompanied with a dried out or withered appearance. There are many reasons why orchids may experience a bud blast. Here are a few.

Change in Environment

Orchid flowers may start to develop yellow buds due to the shock from a sudden change in environment. This could be due to a number of reasons such as a sudden drop in humidity or temperature, or a sudden change in lighting. Orchids are quite sensitive plants so it’s important to pay close attention to their growing environment.

Insufficient Nutrients

Orchids can also develop yellow buds due to a lack of nutrients. Like all houseplants, orchids need a good balance of nitrogen, phosphorus, and potassium to grow and thrive. The orchid plants should be fertilized with products that contain an equal amount of each macronutrient. Lack of nutrient isn’t the only problem however. Yellow orchid buds can also develop from over-fertilization. You should never add orchid fertilizer at full strength.

Poor Watering Schedule

Watering tends to be the primary culprit for a lot of plant issues. For orchids, it’s important that you don’t over-water the plant container. The general rule of thumb is to water the orchids once a week during winter and twice a week during the warm season. Please note, however, that the watering frequency may change based on other factors like the size of the orchid plant container or the climate conditions.

The key to preventing orchid bud blasts is by stabilizing the environment as much as possible. Despite their sensitive nature, orchids can be quite resilient so don’t feel discouraged by the yellow buds. The next bloom should work out just fine as long as you pay close attention to the above factors.
