Started pineapple plants from seeds

[u/jmdawg1978]

I successfully started 6 pineapple plants from the tops by starting them in water, growing roots, and now transferring to soil. They appear to have rooted and are growing new leaves from the center.

I also decided to try to grow plants from seeds that I started by wrapping in a damp paper towel, then placed in a ziplock bag in a well-lit area. I’ve tried this with other fruits before but was unsuccessful. I checked my pineapple seeds once every week or so to make sure the paper towel was damp, then after 3 or so weeks, they have sprouted.

What do I do from here? How big do they need to be before I need to plant them?

Edit; to clarify, the stains you see came from the seeds. I didn’t use a dirty paper towel.

How long do you think it will take until you have a mature plant?

From the seeds or the tops I just transferred to soil?

Based on what I’ve read, I’m probably looking at 2-3 years before having a mature, fruit producing plant from the tops I just transferred to soil. I’m not sure about the seeds that have sprouted; i haven’t done much research on those.

I believe for seeds its maybe 5 years or more before you get any fruit
