Q.my red hot poker plant is not thriving
I bought it 3 years ago and it made a few flower spikes that year but since then it is not growing. I planted it near where we had removed a cedar tree and it also gets a lot of fir needles from a nearby tree. Is it too acidic? Should I give it some lime? It is in a sunny dry location. I plan to rake away all the tree droppings and replace with Black Gold bagged soil. Should I lift the plant and then replant in the new soil?
Your plant does certainly seem thin and spindly.
I do feel that relocating or amending the soil in this area to replant are both good options for you.
You may want to wait until fall to do this.
Make sure your soil is well draining.
