Lemons and limes have the highest concentrations of Vitamin C of all the citrus fruits, and an added bonus of these plants is that they are easy to grow in home gardens, even in large containers. In fact, growing these pretty citrus trees in containers is the smart way to overcome cold temperatures, which can cause damage to the fruit and the health of the tree itself. If you live in an area that receives only occasional frost, you can grow these citrus trees outdoor, but be sure to protect them from the cold.
Growing Lemon or Lime Trees
Prepare your large container by filling it about half full with acidic potting soil. Then take your young tree out of its nursery pot and gently loosen the rootball slightly. Place your unpotted lemon or lime tree into the hole in your large pot, making sure that when you refill the pot the root system of the tree is covered but that the trunk is not buried.
Plant your lemon or lime tree in a sunny, well-drained location in the garden if you wish. Dig a hole about twice as large as the nursery pot and then dig in a generous amount of compost. Set your young tree in the planting hole and then refill with the soil and compost mixture you dug out.
Water your newly planted tree well and then water it once each week when the soil begins to dry out.
Use a balanced fertilizer intended for use with citrus trees four times a year during the spring and summer. This type of fertilizer typically has an N-P-K ratio of 8-8-8. Lemons and limes do not need any fertilizer during the winter.
Spray your tree with insecticidal soap if you notice any insects chewing the leaves. If you see a sooty residue on the leaves, this could indicate powdery mildew: spray with a sulfur spray or other fungicide as soon as possible.
