Blossoming Questions

I bought five hydrangeas two months ago and all but one are doing great. They are planted in the same garden but the one has barely grown since I bought it while the others are flourishing. Any suggestions?

can I safely grow my hydrangeas in pots? What about in winter?

Why is my hydrangea not blooming?

Once the flower ball is dying off, can I cut “dead head” the flower off of the stem and how far should I cut?

Is it ok to use different hydrangeas in your flower bed?

Why do my blooms look burnt?

What type of fertilizer should I use on my hydrangea?

My hydrangea blossoms are very large and are turning brownish and dropping some petals. Should I cut off the blossoms to encourage new blooms? Otherwise the plants appear healthy.

I think my new flowers are getting too much sun. I have watered 2xs a day. I am in Nj. Weather is hot.

When and what is the best way to remove Hydrangea blooms once they are turning brown, or cycled through their color?
