Water deeply once a week, more often in hot weather.
Mulch helps retain moisture.
Proper watering is essential for rhododendron care.
3. Planting Depth Is Critical
Many gardeners fail at how to take care of a rhododendron plant because they plant too deep.
The root ball should sit slightly above the soil line.

Fertilizing is part of how to take care of a rhododendron plant, but do it sparingly.
Use a fertilizer formulated for acid-loving plants.

Too much fertilizer can harm shallow roots.
Light feeding is the best approach in rhododendron care.
3. Prune for Shape and Health
Pruning is another step in how to take care of a rhododendron plant.
Prune right after flowering ends.
