3 year old President, need help!
My president Clematis is now in its 3rd year. Earlier this spring the top half wilted and it turned black. I cut it down to about 3ft high where it was green. Its now 7 ft tall supported on bamboo canes. What type is the president? When does it bloom- early or late? Does it not flower for first few years? My garden is north east facing and this summer has been awful, not much sun and its been raining every day for nearly 3weeks. Also, the plant is growing from only 2 stems from the soil level. Is this enough and how can i make it send out more stems from the soil? I plan on training it to grow around a window, its NE facing so wil it be ok? I pinch it back often so there is plenty of stems growing outwards but it just seems to me that it needs to have maybe 5 or 6 main stems should be stronger plant?
