Lemon trees are citrus trees that produce an acidic, bright-yellow fruit. Lemons are used as garnishments and flavouring in cooking. Lemon trees may be grown from seeds or via a budding process. Most home lemon gardeners will start off with a container-grown lemon tree from the local nursery. The lemons may mature on the tree but should be picked while the crop is in season to prevent the fruit from drying out.
Lemon trees that grow via the seedling process will usually not mature to bearing fruit for a few years after planting. Trees begun with the budding process will produce fruit in the second to third year after planting. The amount of lemons the tree produces will increase as the lemon tree grows larger. Lemon trees can bear fruit year round, but the harvest may vary with the time of year depending on the type of lemon tree.
