    It could be that it is just a little underwatered, just enough so that it can't support its flowers and so it drops them.

     

    It could also be that you have thrips. These are tiny pests that attack the base of buds and cause them to fall off. They can be very hard to see.

     

    I would recommend increasing water just a bit and also treat the plant for thrips. This article will help:

    Once the weather gets warm, take it back outside. Give it a phosphorus rich fertilizer and it should bloom wonderfully.

    It may have thrips. This article will help with that:

    It also would not hurt to increase watering. While you are watering, it may simply not be enough for the plant.

    Mandevilla favor humid conditions. If your plant is exposed to the sun, the soil may be too hot. Try misting/spraying the leaves with water in the mornings and keep the soil moist (NOT wet). You may also want to consider moving your plant (if possible) to an area that doesn't receive direct sunlight for extended periods of time.

    It sounds like a fungus, likely black spot. Treat the plant with a fungicide and this should clear up the problem.
