While everyone automatically thinks of the thicker sturdy canes for using as stakes, I'm thinking more on the line of thin stakes for marking garden beds, marking newly planted items, holding up orchid flowers, etc. Just about everyone I know who is growing and using their bamboo throws away the thin stems. But I find them really useful for lightweight stakes.
Easy to use
Didn't cost me a penny
Very handy since they grow right here on the farm
1- Propping up orchids.
2- Marking the corners of a newly created garden bed.
3- Marking a plant or a pumpkin so that I can see it and find it again.
4- Holding a temporary garden label.
5- Marking that need special attention, such as pumpkin blossoms that need to be kept treated with dipel.
I often color code the top of the stakes for one reason or another. Leftover paint makes a good marking system. Green= save seed from this variety. Red = don't save seed. Yellow = evaluate for possible seed saving.
I'm sure there will be plenty of more ways to use thin bamboo pieces as I create this homestead. But this is what I'm doing so far.
