Blossoming Questions

I was given a lovely Vanilla Strawberry Hydrangea and the leaves are turning yellow. I read that watering on top can make that happen. I checked the soil and it’s good and have mixed in some food. What am I doing wrong?
I am wondering if I’m doing something wrong since one of our Endless Summer hydrangeas is not blooming. Both hydrangeas were planted at the same time. We added some soil meant for Azaleas. The hydrangeas are in the shade all day. We have wrapped a soaker hose around each plant so they get watered at the same time. The flowering one is planted next to a man hole which limited its growth on the right side. They are planted in a heavy clay soil. Please help! How long should we be watering them?
Watering tips please!
I purchased back in april planted them around they same time. They did great for a week or two before after that the flowera look dryed up or burnt. I been watering a least twice a day as recommended since they are heavy drinkers. My ph is around 7. Do you have any suggestions, the foliage looks pretty good. Do I need prune the dead flowers? By the way this es endless summer hydrangea.
About 3 weeks ago I planted summer crush hydrangeas in zone 5 in NE. Per you site and the tag it claims these plants can have full sun in zones 4-9. I planted these facing east and given the sun rise I believe they are getting about 8 hours of sun. Since it’s gotten a little warmer I’ve been noticing them drooping a little come the end of the sun time. They seem to re bound after they are in the shade and or I water, but I’m concerned since it will only get hotter here. Is this just b/c their are newly planted or should I be concerned I planted them in too much sun? Also, how much should I be watering them? Thanks
AM I OVERWATERING OR UNDERWATERING MY HYDRANGEAS?
My hydrangea flowers are drying up even though the leaves look green and lush. What could it be?
I live in Texas where the summer months hit 100+ degrees every day. I would like to set up an automatic drip system for my hydrangeas. How long and what time of day should I set the timer for?
Can I plant my BloomStruck® Hydrangea in a pot?
I just purchased Endless Summer® hydrangeas. Can I leave them potted until next spring to plant without injury?
