Sorry for the 90 questions, kelloggsupply. What type of hydrangea are they? Can you please post pictures of each plant? Are they root bound? Are the plants besides each other or far away? How old are the plants? Exactly when did symptoms start? What happened to the plants at around that time? Are they wilted during the hot part of the day only but perk up at night/by morning? If you insert a finger into the soil at a depth of 2-3", does the soil feel dry, damp or wet. Extract a plant from one of pots and insert a finger at the bottom part of the soil; does the soil at the b bottom of the pot feel dry, damp or wet? Can you tell if the water drainage holes are blocked? Can you list the symptoms that happened in the order that you observed them? Thanks in advance!
