Q.No fruits or flowers just leaves on every plant
The passion fruit vines are two years old and never brought any flower and fruit. The lemonade tree bears just one fruit for the second consecutive year and even that remains hard and green. The bougainvilleas are supposed to be flame red but instead they’re a green bush all year around. I checked the soil and it’s 7-7. 5 pH everywhere. What am I doing wrong?

It sounds like your soil has too much nitrogen. It makes lots of leaves but little in the way of flowers and fruit. Add some phosphorous, such as in bone meal.
