I have dark purple and white iris that bloom alot every year but they won't stand up. As soon as they bloom the weight of the flower makes the stem fall to the ground. Do they need to be planted deeper? What can I do please? |
Unfortunately, some iris are simply incapable of supporting their own stems in bloom. This is often made worse by rain storms in the spring. The only solution is to grow a different, sturdier variety or to stake them one by one. Planting them deeper would not help and might cause the rhizomes to rot. |
