I have a bundle of branches from a North American Maple in my yard, just cut down while pruning the tree in the spring.
I'm contemplating whittling down some 2-foot-long sticks to use as simple trellises for foot-tall young tomato plants (one per plant, stuck into the soil at the base).
Is there any risk of the Maple sprouting and/or sapping nutrients from the tomatoes? Should I heat them? What's the best temperature to heat wood, in order to sterilize but not burn it?
