I've also seen small plastic water bottles (or you could use a piece of plastic) used to propagate bushes that don't readily bend down to be pegged for propagation. You cut the bottom off the bottle, then slice it open the length of the bottle (unless the stem is thin enough to readily slip through the cap end) After the stem is prepared, you place the bottle around the stem, and use what ever means you choose to hold the cut closed and hold the bottle in place. You might need to use a stake to keep the weight of the set up from bending the branch down too far. Fill the bottle up with damp planting medium of choice, and keep it watered until you get good root growth.
Tomatoes can easily be propagated from cuttings, the same way you would a house plant.
My blueberries of choice are big, and sweet, and the plants must be on the short side: i've chosen varieties advertised to top out at 4' or less. I wouldn't call Chippewa a wild type.
