Watering your citrus trees isn't about sticking to a strict schedule. Instead, pay attention to the conditions surrounding your trees.

'The water requirements for citrus trees depend on various factors such as age, size, species, weather, and soil type,' explains Fern Berg, a plant expert.

'For instance, studies from the University of Arizona indicate grapefruit and lemon trees consume about 20% more water than orange trees, while mandarins require around 10% less,' she notes.

It's essential to understand the specific needs of your tree to determine its watering frequency.

'Regularly checking the soil around your tree can help you decide when to water,' says Fern. 'Newly planted trees require more frequent watering as they establish their roots. Initially, water them every few days, tapering to weekly once established,' she adds.

'For mature trees, allow the soil to dry a bit between waterings, but never let it go completely dry for long periods,' Fern advises.

Use your finger to check soil dryness or consider a moisture meter like this moisture meter from Amazon. 'Aim for the soil to be moist around 8-12 inches deep. If only the top layer is wet, you need to water longer and deeper,' suggests Allen Tate, an arborist.

Once you know it's time to water, grab your watering can.

'Citrus trees should receive deep watering rather than frequent light watering. Focus on how long you water instead of how often,' advises Allen.

Ensure the moisture penetrates down to the root zone for optimal hydration.

'Water slowly and deeply to allow proper soil penetration,' Fern recommends.

When watering, target the area beneath the tree canopy, not just the trunk. 'Direct your watering to the drip line, where the branches extend outward,' Allen explains.

If your citrus trees are in a kitchen garden, reduce watering during wet spells to keep them thriving.
