5. Pineapple
Cut off the top and remove any remains of the fruit. Leave about 2,5 centimeters of the leaves around the base. Plant it in a warm spot and water it regularly. You can also place it in a container and pour some water in.
Once the plant starts releasing “roots” water it once a week. Pineapple requires patience, and you will enjoy the first fruit in 2-3 years.
