Can I grow tropical fruit trees in container up north?
Most of the indoor plants are tropical or subtropical – which means, they need warm temperature in range between 50-90F. Indoor conditions may be suitable then for almost any tropical plant. However, blooming reqiures lots of light (energy) – make sure you can provide it. In order for fruit to appear the flowers must be pollinated by insects. Take the plant outside during spring and summer after the danger of frost then move your tree indoors during the winter. Most tropical trees can not withstand temperatures below 32 degrees for long periods. If you are growing in a greenhouse or fully indoors you will need additional artificial lighting or very sunny window. You will also need to learn how to hand pollinate, although some fruit trees will still fruit without hand pollination.
