When to water citrus trees
When it comes to watering your citrus trees, it isn't a case of setting a schedule to stick to. There are a few things to observe before picking up your watering can.
'The amount of water a citrus tree needs is determined by many factors including age, size, species, climate and soil type,' says Fern Berg, plant and gardening expert at Tree Vitalize.
'For example, research from the University of Arizona revealed water use for grapefruit and lemon is about 20% higher for that of oranges, and mandarins about 10% less,' she adds.
It's therefore important to establish the circumstances of your specific tree and do some research around it to understand how often it will need watering.
'Monitoring the soil surrounding your tree is a good way to determine when to water,' says Fern. 'Newly planted trees need more frequent watering while their root system becomes established. In dry weather, this means watering every few days for the first few weeks, gradually reducing to once per week,' she adds.
'For mature trees, the soil should dry out slightly between watering, but never be completely dry for an extended period,' Fern says.
You can use your finger to assess how dry the soil is, or use a moisture meter like this soil moisture meter from Amazon. 'The general goal is to have the soil be moist around 8-12 inches below grade. If you stick a soil probe in and only the top few inches are wet, you know you need to water more and for longer,' says Allen Tate, arborist at Blooma Tree Experts.
How to water citrus trees
Once you've established that it's time to water your citrus tree, you can pick up your watering can to give your tree a drink.
'Like any tree, citrus trees should be watered deeply, not often. Focus on duration of each watering, not frequency,' says Allen.
You want to ensure the water reaches the lowest levels of soil so that the entire root system receives sufficient moisture.
'When you do water, do so slowly and deeply. This will allow the water to penetrate the soil and get to the root zone,' says Fern.
As for where to aim with the water, Allen advises observing the canopy rather than than watering around the trunk. 'The watering should be focused around the drip zone of the tree - think of drawing a straight line down from the outer edges of the tree canopy, that's where you water,' he says.
Reduce watering in wetter weather if you're growing citrus trees outdoors as part of your kitchen garden and you'll soon have lots of fruit to harvest.
