Hello: My rhododendron planted years ago looks tired and not growing well. There are yellowish and dead leaves. Can I use miracle grow? And is Mulch okay? Please suggest. Thanks.

You should be able to buy a feed specifically for Rhododendrons as Meadowland says. Mulch with an ericaceous compost will also help. They naturally grow well in acidic soils.
welcome to GoY too.
