Blossoming Questions

Hi, I bought two ES twist n shout plants from Real Canadian Super store. Grown in similar conditions. One plant is blooming nicely and the other is not blooming at all. Wondering why.

Website says to fertilize in early spring or summer so does that mean you only fertilize one time? But it also says follow instructions on label, which mine says feed every 14 days. I bought the Scots company garden pro water soluble miracid acid loving plant food. So do I only do this once or do I feed every 14 days?

My Endless Summer Hydrangea bushes are producing smaller, but many, blooms. These bushes have always produced much larger blooms which I prefer. Is there something I can do to get the larger blooms again next year? I should state we were making the mistake of cutting these bushes down to the ground each fall, so were getting very few blooms. Last year we did not cut them back at all and I have plenty of blooms but small in size. Hoping there is a way to get lots of the big ones again!

The Summer Crush label says full sun but videos say not full sun. Can they be full sun?

Why do the blooms only flower around the edges and the buds not open in the middle?

Should I cut the almost dead flowers off?

First time with a summer crush hydrangea. Planted in most sun . Been 2 months doing great. Just wondering if should cut off the dead blooms. Or should I say discolored faded ones.?? They still look ok and I read on the tag. The less you prune the better ??? So just wasn’t sure??

Where is the best place to plant my endless summer. I’m thinking east or south? And little more detail like 6-8 hours of morning sun?

Where on the endless summer stem do I cut the blooms when I want to use in vases or because the bloom is spent and needs to be removed?

We have two hydranges that appear healthy and growing , but have never bloomed.
