Q.Yellow Leaves In Hydrangeas

Zone 94010 | Anonymous added on September 17, 2021 | Answered

Last year the bushes are badly blotched from exposing to strong sunlight in daytime (please see the blotched leaf photo). This summer we learned the lesson from last year, we put sun filtered mesh over the hydrangeas to protect them from too much sunlight.The plants go on well and blooms with big beautiful flowers in June and July (see photo). We also cut off the flowers and bring in home for home display, we have been very careful not to cut down to the next nod of the stem. As the weather gets cooler this week, we just see the yellow leaves, I have removed them one by one without disturbing the branches. (please see the photo). For your information, we applied only one time of fertilizer during early spring this year, and our sprinkler is set 3 times a week, each time for 15 minutes. We would deeply appreciate it if you could advise what we could do. Thank you!

I would advise feeding multiple times per year, or change to a stronger granular slow release. Check the pH, as well.

Make sure to watch the watering. It is a delicate balance of keeping the top of the soil slightly moist, without it being too wet.
