Lemon trees may grow in containers. However, lemon trees grown in pots are generally smaller than trees grown from the ground. Lemon trees from containers usually bear fruit earlier. Varieties like the Ponderosa dwarf or Meyer improved dwarf are excellent choices that allow an owner to move the trees indoors once temperatures begin to drop below 50 degrees Fahrenheit.
The needs of lemon trees grown from pots are similar to those of plants grown from the ground. Potted soil should remain moist and receive fertilizer on a regular basis. Lemon trees have a high humidity need, and this need can be met by placing the pot on a pebble tray or misting the leaves on a daily basis. The tree requires significant sun exposure to provide the energy required for fruit production, but direct exposure causes leaves to burn. The trees do well with grow lights or warm fluorescent lighting.
Lemons stop ripening once harvested. On a tree inside the home, they may require up to a year to get ripe. Fruit should be cut from the tree using scissors to prevent damage to the plant.
Lemon trees add attractive foliage and fragrant blossoms to the home. The plants naturally take on a shrub-like appearance but may be shaped into a tree. The size of the planter pot used for the lemon tree determines the maturation size of the plant.
