Citrus trees need regular watering and applications of fertiliser to do well. It’s recommended to fertilise with blood and bone or well-rotted animal manures every three to four months. Also apply a special citrus fertiliser in winter to help sustain fruits; spread it evenly around the tree and water in well after the application. Be careful not to allow fertilisers to touch or build up around the trunk. If you have citrus in tubs, use slow-release fertiliser regularly, as well as manure pellets every season.
WHERE ARE MY LEMONS?
If your citrus is not fruiting, it’s probably due to a lack of sun or food. Citrus trees are known as gross feeders, meaning that they need regular applications of fertiliser. Fruit drop can also be a problem, most likely caused by irregular water supply when young fruits are forming (straight after blossoming) – this normally coincides with the first hit of hot weather when trees are particularly sensitive. Air pollution can be another reason, as young buds don’t like smog, so if the air quality is bad during this time, your citrus crop can suffer as a result.
