Bud drop from indoor hibiscus plant.
I purchased 2 hibiscus indoor plants just before Christmas from Thompson and Morgan. They arrived in beautiful condition and one bud came into bloom within days. There after the buds have failed to open and simply drop off. What can l do ? In every other respect the plants look healthy and new growth is apparent. I phoned T&M for advice which was to keep them moist and use a fine mist . This l do but still the buds fall off. Help would be very appreciated.
Make sure you keep the soil moist at all times, not wet, just moist. Keep it away from cold, drafty windows and doors. I hope your plants are simply adjusting to a new environment and will settle down soon. I'm sorry to say that insects are often the cause of flower bud failure in hibiscus. Take a good hard look for tiny thrips or aphids. These can be difficult to eradicate pests in greenhouses. If your plants are infested, I'll bet T&M will replace them.
