Ok, it's not exactly bamboo sticks. It's rather the function of them I describe. The candy smelling, white blooming bush; schersmin. I have one in my garden and every spring, a few stems are dead (while new ones sprouting). These dead ones are perfekt as growing support, straight, sturdy and long lasting.
This is how my borlotto lingua beans looks with the stems as support. During the winter they are stored outdoors leaning against a wall and holds the next growingseasons without breaking.
Picture of the lunch, squash, salad, leaves from celeriak, radish, onion tops and pesto of dill.
