Blue Hydrangeas

I planted two blue hydrangeas. They started growing good but now they are turning yellow. Will red cypress mulch kill or hurt my hydrangeas? Also, can I use Epsom salts?

The red cypress is not the problem. They likely need more water. If they are newly planted, they need lots of water until they are established. Increase watering and that should help.
