This is a small, widely branched tree that grows 10 to 20 feet (3-6 m) high. It is thorny and evergreen and its leaves are narrow and ovate and light green. The flower buds are in pairs or single. They are tinted purple. The petals are white inside and purple on the outer surface. The fruit is usually pointed at both ends and light yellow. Its flesh is light and its juice sacks are thin. The seeds are ovoid and smooth. Lemon trees are grown as pot plants and outside in regions fairly free of frost. The origin of the Lemon is unclear. Its native home may have been southern China and adjacent parts of Upper Burma, from which it spread into India and westward.
One of the great advantages of the lemon is that it will grow in relatively poor soil. The recommended soils are sand, clay and sandy-clay-deep, with high permeability and good drainage. Black soils are also suitable if not lying over calcareous subsoil. Ph should be between 5.5 and 6.5.
Citrus trees can make very attractive container plants for those who have the space and the access to natural light indoors to support citrus growth or for those who need to move their plants inside occasionally to escape winter freezes. The container must be large enough to give the citrus room to grow. Container you choose, make sure that it has holes in the bottom to allow for drainage.
All citruses require lots of sunlight to grow properly. You may wish to choose partial shade as opposed to full sunlight to slow the growth of your tree and acclimatize it if you plan to move it indoors from time to time.
When providing nutrition to citrus trees, it is important to consider both the specific mineral needs of the plant, and soil conditions that affect a plant's ability to take up nutrients.
The rough lemon is widely grown from seed.
