What can you feed to peonies to keep their stems from drooping?

Answer 1

Do you live in the south? Because peonies don't do well down here.

Also, they plants are very poisonous. A tea made from one bloom is said to be strong enough to kill a person.

Answer 2

Weak Flower Stems means either deficient soil or excess shade,
Weak stems that do not stand up well when the blossoms are out indicate either a weak stemmed variety, a phosphorus deficiency, or the plant is in too much shade. Fertilize with a balanced, high-phosphorus fertilizer. That is the P of N-P-K. Give the plants bone meal. One handfull scratched into the soil.
If the plant is in shade, move it to a sunny location. If the problem persists, you may have to either stake the flower stems or try another variety.
Apply bone meal or other low nitrogen, complete, slow release fertilizer once a year after flowering (and deadheading.) This is the time of "eye" formation.

Answer 3

Feed Miracle Grow like any other flower. Peonies are hardy plants with a good root system. Even after moving the plant, another one grew in the same place as I didn't get all the roots.

One shovel full of aged horsemanure per year
