Water newly planted citrus trees 2 to 3 times a week during the Spring and Summer seasons of its first few years. Provide enough water to completely saturate the soil around the roots every irrigation session.
This is flooding the well a few times if water with hose. About 5 - 7 minutes if watering with bubbler. 15 - 25 minutes for a 15 gallon trees if watering with Sprinkler, and much longer if using drip unless its a perforated drip line.
The key to watering citrus trees is deep water and as frequently as needed depending on the season.
Water deep but infrequent. Citrus trees thrive when they receive enough water to soak their entire root system, followed by a period where the soil is allowed to partially dry out.
1. In-Ground vs. Potted Citrus Schedules
Your watering schedule depends heavily on whether your tree is planted in the ground or kept in a container:
| Tree Type | Summer Schedule (Peak Heat) | Winter / Cool Season Schedule | How Much Water? |
|---|---|---|---|
| Newly Planted (First years) | 2 to 3 times a week | Reduce based on local rainfall | Deeply fill a soil basin around the trunk. |
| Mature In-Ground (Established OLD) | Every 7 to 10 days | Every 3 to 4 weeks | A heavy deep-soak (roughly 4–6 inches of water total per month). |
| Potted / Container | 1 to 2 times a week (Daily in extreme heat) | Every 1 to 2 weeks (Check soil depth) | Drench until water drains out the bottom holes. |
2. How to Test for Soil Moisture
Never water on a strict calendar schedule alone. Always test the soil first:
- The Finger Test: For potted trees, poke your finger into the soil. The top 2 to 3 inches should feel completely dry before you water again.
- The Squeeze Test: For in-ground trees, dig down about 6 inches mid-way between the trunk and the outer edge of the branches (the drip-line). Squeeze a handful of soil. If it forms a ball and holds together, the soil is still wet enough—do not water.
- The Pot-Weight Trick: For small containers, lift or tilt the pot. You will quickly learn to feel the difference between a heavy, fully hydrated pot and a light, dry pot.
3. Rule of Thumb for Rain Adjustments
Keep an eye on local weather. If your area receives 0.5 inches of rain or more in a single storm, you can safely skip watering for that week.
4. Warning Signs to Watch For
Citrus trees will explicitly tell you when they are unhappy, though the signs can sometimes look similar:
- Signs of Underwatering: Leaves will fold inward or curl vertically. If the tree is extremely thirsty, leaves or blossoms will drop off. The tree will generally bounce back quickly without permanent damage if soaked promptly.
- Signs of Overwatering: Leaves turn a pale, sickly yellow and may drop while still soft. The soil stays muddy or smells swampy, which quickly leads to root rot—the leading killer of backyard citrus.
