Blossoming Questions

ONLY 1 OF 4 PLANTS BLOOMED LAST SUMMER. THIS SPRING I HAVE GREEN BUDS AT GROUND LEVEL BUT NOT ON LAST YEAR’S WOODY STEMS. THE BUDS ON THE OLD STEMS ARE BROWN AND APPEAR TO BE DEAD. SHOULD I CUT THE OLD STEMS TO THE GROUND? HALFWAY? WHAT AM I DOING WRONG?

WHEN FLOWERS WILT CAN I PLUCK THEM OFF SO NEW ONES WILL COME IN?

I HAVE A BLOOMSTRUCK REBLOOMING HYDRANGEA AND IT SEEMS AS THOUGH THE BUDS HAVE DIED ON LAST YEAR’S GROWTH, BUT I DO HAVE NEW GROWTH COMING IN. SHOULD I BE WORRIED?

CAN I PLANT MY PLANTS IN JUST DIRT?

WHAT IS THE TALLEST HYDRANGEA THAT WILL GROW IN FULL SHADE?

DO YOU HAVE ANY FERTILIZING TIPS FOR MARMALADE POTENTILLA?

HOW CAN I REVIVE MY LITTLE DEVIL NINEBARK?

THE FLOWERS ON MY SPIREA ARE TURNING BROWN. HELP!

SHOULD I DEADHEAD THE DYING BLOOMS ON MY ROSE BUSH?

WHAT SLOW RELEASE FERTILIZER WOULD YOU RECOMMEND FOR MY AMBER JUBILEE NINEBARK?
