How to Grow Hydrangeas – Solving Common Hydrangea Problems – Hydrangea bushes are relatively easy to grow.
Just give them lots of water and sufficient sunshine, and you’ll have a healthy happy bush that blooms lovely heads of dainty florets.
But if you find that your hydrangeas are not as lush and fertile as you expected them to be, it’s either your plants need a bit more TLC or there’s a problem you need to solve.
Here are some common hydrangea problems, how to diagnose them and what you can do to solve the problem:
Problem: Too much sunshine.

How to Diagnose: You will notice flowers that look dry and wilted.
Solution: Water frequently. Hydrangeas need a lot of water to keep itself hydrated. It thrives best in moist soil.
Water your hydrangeas at least twice a day. In warmer climates, you might want to do this as often as 4 times a day to prevent water in the soil from evaporating and leaving your hydrangeas parched.
Problem: Winter frost.
How to Diagnose: Buds that don’t bloom into flowers.
Solution: During winter, protect your hydrangea buds from the harsh weather.
Hydrangeas cannot survive temperatures below 25 degrees fahrenheit. What you can do is insulate your hydrangea bush from the winter cold.
To do this, create a perimeter atop and around your hydrangea bush using stakes and chicken wire.
Next, cover the chicken wire with fall leaves. Keep your plants covered throughout the winter.
How to Diagnose: You will see the insects on the plants. Another telltale sign is injured leaves.
Solution: Use the appropriate insecticide to get rid of the pests.
Problem: Powdery mildew
How to Diagnose: Unhealthy and discolored leaves
Solution: Use an appropriate fungicide. Make sure when you water the plant, to water at the base of the plant.
This helps keep your leaves dry, which will prevent fungi from forming on your plant.
