Why don't my hydrangea and marigold have any flowers?

If it has been planted for many years then it is probably not in a sunny enough spot. If it has been only a year or two you may need to wait longer. Mine didn’t bloom until last year, 3 years after I planted it. This year I have even more blooms! As for marigolds, make surethey are in full sun and give them fertilizer.

Here's some good info Maggie!

my neighbors cut their hydrangeas every fall and they never bloomed. I read that they should not be trimmed until June or July and I have big beautiful, multicolored blooms. Deadhead your marigold when blooms die and they should grow back
