My shipment of orchids looked great when they first came in. I've had them for about three weeks, and I've already sold a few. None of my customers have complained about them or anything. I know orchids don't like water, so I've been watering them sparingly. The rest of the plant looks okay. I don't normally work with orchids and I only sell houseplants when I get a good deal from a wholesaler. In other words, I have no idea why they're dropping their blooms and could use some help.
