Blossoming Questions

I purchased an Endless Summer hydrangea from you at least 6 years ago. The plant is very healthy, however it does not bloom like it should. The most blooms I’ve ever had in one season is 3. So far this year there is only one and there are and no buds developing. What is it lacking? It gets plenty of sun. And it seems to demand a lot of water as the leaves often droop if not watered. What nutrients would you recommend?

What type of fertilizer should I use on my hydrangea?

We planted 2 Kashmir rose plants, about 5′ apart. The problem is they are drooping over in the bed. Do we support them in an up right position or leave them droop on the ground?

Can and when can you prune Vanilla Strawberry Hydrangeas? Is there a rule of thumb as to how much I can trim back?

Why is the plant turning black?

Did cutting flowers last year in the fall to dry in vases cause my hydrangeas to not produce any flowers this year?

My endless summer hydrangeas look like they are dying. The pots didn’t have drainage holes so soil was always wet. Put holes in now for drainage. Will they come back?

I have four Endless summer hydrangeas that are about 5 years old. Planted in various areas of sun to partial sun in our yard. I rarely get blooms. This year I got one bloom of all four plants. I cut them down in the fall as I thought this was the variety that bloomed on new wood. Is this the problem?

If the flowers are drooping to the ground, should I prop them up with supports?

My hydrangea blossoms are very large and are turning brownish and dropping some petals. Should I cut off the blossoms to encourage new blooms? Otherwise the plants appear healthy.
