If you are considering buying new trees for your home, you may want to look at purchasing citrus trees. Especially as an average size tree is probably nowhere near as expensive as you may think it is.
If you are looking for trees that are aesthetically pleasing, as well as trees that grow fruit you can eat, citrus trees are usually the best choice.
Fruit grows in different climates -- If you choose the right trees, it is possible to grow fruit even in climates that are quite cool.
Just be sure to choose key limes, orange or Lemon Trees and then plant the small trees in containers that you can move around. When the weather becomes cooler, you can then move them indoors to protect them from frost.
You can make jams, canned and dried fruit -- Once your trees begin bearing fruit, you can pick it and use it for jams as well as canned and dried fruit.
Just imagine having trees in your garden that will enable you to have all the jam and fruit you could ever need, without having to go to a store to buy it.
After all, as they grow fruit, these trees give off a lovely smell. One that will permeate both your garden and your home for several months every year.
