Lemons are more cold-sensitive than all other citrus trees. Due to this cold sensitivity, lemon trees should be planted near the south side of the home. Lemon trees need protection from frost. Growing them near the house should help with this. Lemon trees also require full sunlight for adequate growth.
While lemon trees can tolerate a range of soils, including poor soil, most prefer well-drained, slightly acidic soil. Lemon trees should be set slightly higher than ground. Therefore, dig a hole somewhat shallower than the length of the root ball. Place the tree in the hole and replace soil, tamping firmly as you go. Water sufficiently and add some mulch to help retain moisture. Lemon trees require deep watering once weekly. If necessary, pruning may be done to maintain their shape and height.
SOIL: Like most houseplants, citrus prefer a slightly acid, all-purpose mix, which you can get by using a peat-moss based growing mix. (Remember, you get what you pay for, so don’t go for the cheap products.)
TEMPERATURE: Lemon trees thrive in a normal temperature range of 70 degrees during day to 55 degrees at night. TIP: Though the plants are evergreen they will go into dormancy and stop growing below 54 degrees F.)
Lemon trees and other citrus fruits grow particularly well in tropical and subtropical climates. Sour citrus trees such as lemons don’t require higher temperatures as do sweeter citrus fruits, making them a possibility even for those in cooler coastal areas. While no quick fix forces your lemon tree to grow abnormally fast, proper growing conditions do encourage the tree to grow properly. Poor drainage, lack of sunlight, improper irrigation and lack of care can slow the growth of your lemon tree, causing poor production of fruit.
Uses of lemon:-
The juice of the lemon may be used for cleaning. A halved lemon dipped in salt or baking powder is used to brighten copper cookware. The acid dissolves the tarnish and the abrasives assist the cleaning. Lemon oil and orange oil are also used as a nontoxic insecticide treatment.
A halved lemon is used as a finger moistener for those counting large amounts of bills, such as tellers and cashiers.
Lemon oil may be used in aromatherapy. Lemon oil aroma does not influence the human immune system, but may enhance mood. The low pH of juice makes it antibacterial, and in India, the lemon is used in Indian traditional medicines.
