Why plants are not blooming this year

Question

My tropical hibiscus bloomed all winter in the house. I brought it outside after memorial day and has only had a few flowers so far. It is growing, leaves are green but no flowers.

My hydrangea has not bloomed this year. Not sure what to do

Thank you

Answer 1

Did you fertilize your hibiscus before bringing it outside?
