In between those days, I made a couple of attempts to propagate my Petunia. I tried:
- Stem cuttings in water - I took a 4-inch stem from a healthy Petunia, removed a couple of the bottom leaves and soaked the bottom in water. I tried this in both a zip locked plastic bag and an open glass container. After about a week or so, the stem wilted. No roots.
- Stem cuttings in soil - Same type of cutting only I placed it in a pot with soil with medium sunlight exposure. In less than a week, the stem wilted. No roots.
- Simple Layering - I scraped off part of the stem (on the node) then I bent the stem to touch the soil. I covered the stem with additional soil. The stem wilted! No roots.
- Seed Germination - I collected Petunia blooms that i deadheaded and dried them out in the sun. After a couple of days, I took what I think are seeds inside and sowed them into small pots. I put multiple seeds per pot to increase my chances. It's been almost two weeks. No sign of germination.
Between those experiments and cats bumping and breaking my stems, my red & white Petunia now looks awful (the ugly looking plant on the right). Contrast with the purple one, which continues to show lush foliage and plentiful blooms.
