I recently had to leave my house for six weeks, and had a plant-sitter take care of my plants. She did OK, but didn't water enough, and a lot of plants were stressed out. Now that I'm home and watering correctly, all heck is breaking loose. First, my N. hamata sent up several tiny basal shoots from the roots. Now, I notice several other plants flowering. P. esseriana, P. primuliflora, D. madagascariensis, D. paradoxa, and some others are all flowering suddenly.
Has anyone studied stressing plants in a controlled way to get these results? Is this something perhaps that could be done deliberately from time to time to induce flowering or offshoots?
