How do you fix a broken sunflower stem?
Hold the broken edges together and place the stake or splint along the edge. Wrap closely with a stretchy binding such as nylons, plant tape, or even electrical tape. The binding needs to have some give so the stem can grow. Brace the stem if it is dangling so there is no additional pressure on it as it heals.
