Many of the best cut flowers grow 3–5 feet tall on stems that cannot support their own weight in wind or rain. Providing support early keeps stems straight and prevents breakage.
The most efficient method for rows of cut flowers. Stretch a layer of netting (6-inch mesh) horizontally over the bed, supported on posts at the corners and edges. As plants grow up through the grid, each square keeps a few stems upright. For tall flowers like dahlias and delphinium, add a second layer of netting 12–18 inches above the first.
Use bamboo stakes, wooden dowels, or metal supports for individual plants like dahlias, peonies, and delphinium. Tie stems loosely with soft twine or fabric strips. Install stakes at planting time to avoid damaging roots later.
Metal ring supports placed over peonies in early spring allow the plant to grow up through the ring, which then holds the heavy blooms off the ground. Install when shoots first emerge.
