I've looked on Google but can't find an answer to my question.

I have two new jasmine plants, one planted in the ground, and one in a
container. Both planted out about 6 weeks ago. They are both growing well
but I cannot see the start of any flower buds. On Google I see different
flowering times. Some sites say flowers from June and some say July.

What should I feed them? I have been using miracle gro (but not as often as
I should of). Would they like a tomato feed instead?
