Flowers are especially beautiful when the blooms are large and lush. But that also harbors dangers. They can buckle easily. If the stems bend , then you don't have to cut them off yet, you can try to raise them up again instead of cutting them off.
Particularly affected are sunflowers (sometimes up to four meters high), but also peonies (very full and large flowers) and gladioli, which are also very long-stemmed.
Wooden stick serves as splint
Take a wooden stick and use it as a splint. The rod is then attached at the top and bottom with a plaster or wire. If wire is used, be careful not to scratch the stem.
Dry the flower instead of throwing it away
If this support doesn't hold up, you can also tie the stem to a fence or to an adjacent, more stable stem. If nothing helps, then cut off the flower and put it in the vase. There she will certainly delight you for a few more days. Alternatively, you can also dry the flower and use it as a drying arrangement.
