    Planting is warm weather can lead to more stress in newly planted shrubs.
    Since the blossoms are the most outer part of the plant they may be suffering the worst as the shrub works on setting it's roots.
    Make sure you are watering daily to keep the soil moist but never soggy.
    I would trim the blossoms from the Hydrangea do help reduce it's work load.
    You will have to do without flowers this season, but concentrating on getting the plant established and healthy will reward you with flowering next season.

    This appears to be, either a fertilization issue, or a pH issue. It is always good practice to spread dolomitic lime each spring to keep the pH in check, but I believe that you would benefit from doing that now. You may also fertilize with an all-purpose fertilizer, but it is best to do that in spring. It could also come down to the fact that the type you have has a habit of dying back too far, as the flowers only occur on old wood.

    I do believe that this is a Mophead. This will be pruned in late summer, but no later than early fall. Only prune branches that have already flowered. This article will help: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/prune-hydrangea-bushes-hydrangea-pruning-instructions.htm

    If it continues to grow, and use water, then you will water it as the top two inches dry thoroughly. If this variety does go dormant in your greenhouse, then you will only water 1/4 of a cup once a month. Just enough to keep it alive during dormancy.

    This will depend on the low temps in your greenhouse, as well as humidity along with other factors.
