I intended to do this as an update post to show how the pineapple I first planted 2 years ago has progressed, but it seems I never wrote a post about it then. My little pineapple friend had outgrown it’s original pot, so I transferred it over to a larger home and added a new friend for it in its original place.
To plant a pineapple from the scraps, leave 1/2″ inch or so of the fruit when you remove the top. Check underneath to see if there are any brown dots around the edges (these are the root buds). If you don’t, keep removing thin slices of the fruit until you do. Now carefully remove the lower 1 inch of the leaves so you have a small stem exposed.
This next part I have seen conflicting information about. Some say to allow the pineapple top to dry for a few days before planting and others say to place it in water. The little pineapple top below was done with the water method, and it doesn’t look quite as good as planting the pineapple top dry (how I did the larger plant above). Both plants looked slightly unhappy at first before perking up though, so the smaller plant still might have a chance. Even though it is a bit dry around the edges, there is some promising new growth in the center. Either way you do this, water around the outside of the plant and not at the center as it can cause rot. When planting, do not allow any soil to fall into the center of the plant or cover the stem with soil, only cover up to the top of the fruit.
Pineapples like well drained soil, so you can add vermiculite to the soil to help with this and keep them in a pot that drains. Water daily to keep the soil wet, but not water logged, for the first week. Water once a week after they are established and keep them in a place where they can get plenty of sun.
For those in a cooler climate, pineapples can be kept in pots and moved inside over the winter. They will die if the temperature falls to 32 degrees or lower. We move ours indoors well before that point to keep them happy.
