Do you really want some type of fruit tree but feel that your garden space is too small? Your garden may still support a fruit tree, you just have to shop around for what you want and search through options that will fit in beautifully. There are several fruit trees and bushes that will work in a smaller garden and still give you the look and feel you want with their presence. There are a few things to consider such as upkeep, placement options, climate, and your USDA hardiness zone and so on, but this is the same type of concerns you would have with planting a larger fruit tree. So what are your options?
If you absolutely must have a fruit tree because you love the smell of citrus trees or really want apples, consider some of these trees in the Dwarf variety. Certain dwarf apple trees self pollinate like Sunset and Braeburn apple trees, so you only have to plant one in your garden to get fruit. All dwarf citrus fruit trees self pollinate but another benefit to them is that they can be potted and placed in your garden that way. This means that should you have a severe weather change, they can be brought inside for safe upkeep which is great as they prefer warmer weather. You can also plant cherry trees like Sunburst, Stella and Morello which all self pollinate or even all three as they are small dwarf trees. The thing to remember is the big, juicy cherries can come off of just one.
Using any of these fruit tree options will set your garden apart anyway, regardless of the size of the tree or trees, but maybe you want something that is not seen as much? Try pomegranate. This fruit is gaining popularity quickly as being high in antioxidants and you could grow your own. These trees handle temperature extremes of both heat and cold and are beautiful as well.
