When cutting open a recent store bought pineapple, I noticed some seeds.
I read that the temperature for sprouting pineapple seeds is best between 22C & 28C and that the plants would take around 5 years to fruit from seed.
I'll update if there are any seedlings that come up from this.
On a separate pineapple topic. I recently planted some tops in pots and jars. Observing the roots grow in a jar of water is great for the kids. Of course, Dad does not get any kicks from such 'mucking around' :)
In the past, I have just plonked the tops in soil which contained a decent amount of organic material. Then mulched around the plants. This will continue to be my standard approach when planting heads and pups.
I'm intending to plant out the jar-rooted pineapples within a few weeks.
Update 8th April 2017
14 Pineapple seeds in the seedling tray have sprouted, as well as seeds on the tissue paper (in clear food container with lid). I'll transfer the later to the seedling tray.
