How Often Should You Water a Citrus Tree?

The short answer: water your potted Citrus tree when the potting mix has started to dry below the surface, rather than on a set day. Citrus generally like evenly moist, well-drained soil, not soggy roots. How quickly the mix dries depends on pot size, soil, sun, heat, wind and the season.

How often should you water a potted Citrus tree?

There's no exact number of days that suits every Citrus tree. Potted Citrus dry out faster than those in the ground, so they usually need checking more often, but the right timing still depends on their conditions.

Your Citrus may need water more often with:

• Hot weather and full sun
• Windy, exposed spots
• A smaller pot
• A faster-draining potting mix
• A larger tree, or one that's flowering or fruiting

It may need water less often in:

• Winter or cooler conditions
• Rainy weather
• Shadier spots

Why there isn't one fixed watering schedule

Outdoor pots change with the weather. A hot, windy day can dry the mix quickly, while a rainy week can keep it wet for a long time. Checking the moisture in the potting mix helps you water for the conditions, not the calendar.

How pot size, sunlight and hot weather affect watering

Smaller pots hold less mix, so they dry out faster. Full sun and heat speed things up further, especially in dark-coloured pots that warm up in the afternoon. During an Aussie summer, check more often and water in the cooler part of the day where you can. In winter, your tree is likely to need water less often.

Signs your Citrus tree needs water

• Potting mix that feels dry below the surface
• A pot that feels noticeably lighter
• Leaves starting to curl, droop or look dull

Leaf curl and yellowing can also be linked to pests, nutrients or cold, so check the soil before assuming it's thirst.

How to check the potting mix

The top of the soil can look dry while moisture remains deeper in the pot, or look damp after a light shower while the roots are dry. Check below the surface, near the roots, or feel the weight of the pot for a more reliable picture.

How to avoid drying out and overwatering

• Water deeply until excess drains from the bottom, rather than giving small, frequent sips
• Use a pot with drainage holes and a free-draining mix
• Don't let the pot sit in a saucer of water
• A layer of mulch can help the mix hold moisture for longer
• Check more often in hot weather and less often in winter

Yellowing leaves and soil that stays soggy can be associated with overwatering, while wilting and fruit or flower drop can point to the tree drying out. These symptoms can have other causes too, so look at the whole picture.

Can Sustee help with Citrus watering?

Sustee is a simple moisture indicator that sits in your plant's potting mix. It changes colour according to the moisture level around the indicator:

In outdoor pots, where sun, wind and rain keep changing things, it's an easy way to see at a glance whether your Citrus actually needs a drink.
