6. Pineapples


via lsuagcenter.com

Unlike the cherry trees that are prone to bugs, the pineapple is a tough fruit and it isn’t prone to insects and disease problems. However, this one also takes such a long time to produce fruit – it will take you about two years from the moment you plant it until the harvest. The pineapple requires warm temperature and full sun position, so during cold winter nights protect it from freezing temperatures.
