Each time I buy a fresh pineapple, I cut off the top. Then I scrape away any flesh at the cut point, remove about an inch or so of the bottom leaves, and put it outside on a window ledge so the base can thoroughly dry. After about a week, roots can be seen winding around the bottom stem and the area is nice and dry with no rot.
I then put the pineapple top into about an inch of water and the roots plump up nicely. There does not seem to be any urgency in planting the top as long as the water level is maintained.
Some pineapple tops that were planted in the green, or rainy, season were lost to rot but others did okay. They don't like a lot of wet. Today I planted three more tops.
Ta da! This week I noticed a tiny pineapple emerging from one of the first tops I planted .... this is quite amazing to me, a person brought up in northern climates. Pineapple came in cans or imported whole, so they were pricey. I used to look for Costa Rican pineapples in the Vancouver, B.C., area markets once we knew we were moving here. Now here we are, right where those same pineapples originate.
So, every Friday I will post a photo of our baby pineapple and we'll watch how it progresses.
