Description The lemon tree grows to around 3.5 m (12 ft) and does best in warm, humid climates with mild winters. The fruit varies in size and degree of acidity and are often produced in several flushes of fragrant flowers and fruit throughout the year. ‘Eureka’ is probably the most commonly grown cultivar, producing large fruit and flowers all year round. It is an attractive, almost thornless tree, the best variety for temperate locations and coastal gardens. ‘Meyer’ is smaller, hardier and produces smaller, smoother and very juicy thin-skinned fruit. It is less acidic (can be eaten like an orange or a grapefruit!), more disease free and cold tolerant than other lemons, and also does well in the tropics. Probably the best variety for growing in containers. ‘Lisbon’ is a thorny, reliable and heavy fruiting variety; mostly winter bearing and best for hot areas.
Growing Grows best in a very well-drained, friable, slightly acid, loam soil. They need full sun, protection from wind and regular watering, especially during the summer months. Once established, some varieties will tolerate light frost. They also need regular fertilising, including large amounts of nitrogen, and potassium for good fruiting. Growing in pots All citrus can also be grown in pots, as long as the containers are large. Choose a container of twice the diameter of the root ball. (If the location is not sunny all year round, it is a good idea to place the container on a plant trolley to be able to easily move it into a sunnier spot as required.) Use only reputable potting mix in containers, as garden soil would be too heavy for the root system to become established. Plants in containers dry out much quicker than those in a garden bed, especially if the pot is terracotta which is porous. Especially during the hotter months a container can dry out within in a day! So make sure to water frequently. Fertilising Fertilise a little and often (a sprinkle around the circumference of the root ball, or the edge of the pot if in a container, about once a month or so) with a "Complete Garden Fertiliser", that has all the necessary trace elements and is available in a variety of brands. Pruning Prune only to remove dead, diseased and crossing wood. Pests Citrus trees are subject to a range of virus diseases and can be invaded by many pests including scale, leaf miner, bronze orange bug, spined citrus bug and fruit fly. Citrus are prone to collar rot, so plant it with the graft union well above the soil and keep mulch away from the stem. Propagation Lemons are rarely propagated by home gardeners as this is done by budding, a specialist task. Secret TIP: Citrus like regular overhead watering which will ensure juicier fruit. This does not mean that you have to water your tree from above each time you water, just hose down the leaves on occasion and do so regularly!
