Common Name: Lemons & Limes

Botanical name: Citrus limon & Citrus aurantifolia

Summary

A relatively young genus originating from Northern India, with the modern cultivar that we call lemon turning up in Spain around the 13th century courtesy of Arab traders. Since then, the acidic fruit has become an indispensable ingredient in modern cuisine.

 

Small to medium spreading vigorous evergreen trees, these trees have glossy green leaves, and are in the same genus as kumquat, orange, grapefruit, tangelo and mandarin. Cultivars in Australia include the Lisbon, Eureka and Meyer varieties.

Planting

Pruning

Lemons will respond well to severe pruning any time of year to reduce long water shoots and maintain shape and airflow. Paint trunk and major branches with white water based paint if renovating in summer to avoid bark scold.

Disease and pest management

Citrus gall wasp requires heavy pruning of all galls in June and July to avoid re-infestation. For scale, increase water and fertilise.

Thirsty from Spring to Autumn.

Feeding

Hungry. Feed with high Nitrogen, NPK fertiliser once or twice a year any season.
