    At this point in time, it is likely not transplant shock. That normally occurs within a few weeks of transplanting.

    It may be underwatering. This winter has been odd in many parts of the world. Newly planted shrubs need plenty of water the first year to establish themselves. If it was a dry winter where you are or if it was a warm winter with average rainfall, the shrubs may not be getting the water they need to help establish themselves. I would recommend increasing water to the plants and water them regularly until you see the leaves start to regrow.

    This is likely due to a fungus. Neem oil is an effective fungicide.

    I would prune them back and let the new growth take over from there, though I wouldn't take more than a third of their growth.

    How old is the hedge? Has the hedge been in gradual decline for quite some time or did this just happen after winter? If it is the latter, then your shrub probably sustained some cold damage. For more information on cold injury and a prescribed course of treatment, please visit the following link:

    Is there anything unusual that you can see on the leaves or branches - any signs of disease or fungus or even an insect infestation?

    If the hedge's decline isn't due to winter injury then you may want to consider pruning it back hard in order to bring back new life. However, that would mean losing your privacy for awhile but it might salvage your monetary investment.

    It's difficult to say exactly what is effecting the shrubs, but they can be susceptible to fungus. Rake and remove any leaves that have dropped off of the plants.
    Treat the shrubs with Neem Oil as this both works as a fungicide and pesticide.
    Have you had heavy rain? If the plants are heavily mulched you can pull back the mulch to help dry out the soil.

    This can be a difficult fungus to treat, though the link below has some specific chemical treatment.
