How to grow lemon trees
Prepare the planting site
Choose a position for your lemon tree in full sun and make sure it is sheltered from the wind. Dig the ground over removing any weeds and rocks from the bed. Dig to at least twice the size of the root ball and add sand if the drainage is poor. Also mix in plent of well-rotted organic matter to enrich the soil.
Planting the tree
Plant the lemon tree into the well-prepared hole making sure that both the plant in the pot and the ground where it is to be planted are lightly damp. Keep the soil at the same level to the tree as it was in the pot.
Mulch well with an organic mulch to inhibit weed growth and protect the roots over winter making sure to leave a gap between the mulch and the trunk. This will ensure ample air flow so as not to cause rot.
A deep watering once a week is most beneficial. By watering deeply at ground level it promotes strong root growth encouraging the roots to grow downwards.
With your secateurs, prune out spindly, dead or diseased stems, or any shoots that emerge from the graft at ground level. No other pruning should be necessary, as lemon trees have a compact shape.
