Before you firm up the soil, make sure that the tree is completely vertical and will not fall over. After you have checked that the tree is perfectly vertical you can gently firm up the soil. If the tree's trunk is not yet completely sturdy and can be bent, you need to tie the tree to a stake with a bit of rope. Not only does it look disgusting on the leftover fruits, but it also can come back on the newer fruits, rendering them inedible (unless you enjoy eating fungus). To prevent this malady, you should prune your trees often to encourage good air circulation. Buildups of moisture are the main cause of the brown rot. You should never plant so many trees that you are going to be overwhelmed, though. Only plant what you can handle. Generally if you are getting started on a large amount of trees, you will want them to all be the same type. If they all require the same amount of water and nutrients, you won t have to spend as much time catering individually to the different types of tree. It is most likely that attempting to grow an orange tree in these conditions would be disastrous. One of the more popular types of orange is the Washington Navel . It probably came about as a mutation of other oranges. It originated in Brazil around 1820, and had moved on to Florida within fifteen years. But if you plan on keeping it for years, go for a long lived tree. If you decide on a short lived plant, you are probably looking for something with speedy growth. This means the root system will be particularly aggressive, so be sure not to place it near any septic tanks or other deep rooted plants. The skin is thin and soft. They are great for salads. They range in size from medium to large. They are shaped much like the red delicious apple. The insides are crisp, juicy, sweet, and mild. Many people enjoy them, although they bruise rather easily. They become ripe in late September. They are good for many purposes, and they last a long time if not handled roughly.
