I planted 5 hydrangeas and two have green wood beneath the soil, two have each one green leaf sprout. My fifth shows no sign of life! I did not cut wood down as they are only 12 inches as these were new plants – I do not see anything happening on the old wood. The buds are hard and dark brown (look dead) – they get morning sun until about 1 pm then are in the shade for the rest of the day – soil is moist but not wet and I’ve added fertilizer—is this normal for June? What else can I do to make them thrive?
