| During the first appearance of my alstromeria in May-June, they are erect, and need litle support. As the season progresses, newer sprouts can barely reach 6 inches before toppling over. How can I strengthen the stems of the subsequent rounds of growth? |
| Too much shade causes floppy stems on alstroemeria, as does too much fertilizer. Fertilizer forces new growth and if the flower stems grow too fast, they will be weak and floppy. So, hold off on feeding your plants and make sure they're getting adequate sunshine. That should solve the problem. |
