New hydrangeas- too much water? Not enough sun?

[pth20420]

At a loss on what these plants need! The leaves seem healthy and not dry but the flowers seem somewhat crispy and look like the plant needs water. We have had tons of rain this summer so would be surprised if they really were dry? The ground around it feels somewhat moist, not wet, not dry. It gets filtered sun throughout the day. Large trees overhead. West/south facing.
Thanks for any thoughts!

It sounds like your sunflowers are experiencing an issue that isn’t directly related to water or sunlight. Here are a few potential causes for the symptoms you’re describing and what you can do to address them:

Potential Causes and Solutions​

1. Overwatering:
   • Symptoms: Overwatering can cause root rot, leading to poor flower health even if the leaves seem healthy.
   • Solution: Ensure proper drainage. If the soil is consistently moist and the area has had a lot of rain, you might need to improve soil drainage or reduce watering.
2. Nutrient Deficiency:
   • Symptoms: Lack of essential nutrients can lead to poor flower development and crispy flowers.
   • Solution: Test the soil to check for nutrient deficiencies. Add a balanced fertilizer rich in phosphorus, which promotes blooming.
3. Root Health:
   • Symptoms: Compacted soil or damaged roots can affect the plant’s ability to uptake water and nutrients.
   • Solution: Loosen the soil around the plants carefully and consider adding organic matter to improve soil structure.
4. Pests:
   • Symptoms: Some pests target the flowers specifically, which might make them look unhealthy even if the leaves are fine.
   • Solution: Inspect the flowers for any signs of pests like aphids or thrips. Use appropriate pest control measures such as insecticidal soap or neem oil.
5. Fungal Diseases:
   • Symptoms: Fungal infections can cause parts of the plant to become crispy and unhealthy.
   • Solution: Look for signs of mold, mildew, or other fungal infections. Use a fungicide if necessary and ensure good air circulation around the plants.
6. Environmental Stress:
   • Symptoms: Sudden changes in temperature, humidity, or exposure can stress the plant, affecting flower health.
   • Solution: Ensure the plants are not exposed to extreme conditions. Provide some

the leaves look good. pull away the mulch 3 inches from base to prevent root rot. And then leave it alone.

Thanks! Thoughts on dead heading? Too late in the season?

NO. NO. You do not even know if it blooms on old wood or new wood. Stop. don't do anything to it. Ask me again next year this time, then pics. not just the top shot , want to see side shots. If in January you want to take off the dead flowers, fine.
