Avocado trees work like thirsty machines to produce fruits. The need for water for them ranges according to factors like the weather, the kind of ground and the age of the tree. For good health and rich fruit, full growing avocado plants usually require at least 40 to 50 inches of yearly rain.
In regions like California, where the climate is dry with little rain, giving enough water to the trees becomes a real problem.
How Much Water Do Avocado Trees Need
In the summer season big avocado trees require around 2 inches of water, whether by means of rain or watering, weekly. On the West Coast, one mature tree can use almost 91 liters of water in one day during the period of watering. That is a lot of water for a single tree.
Actually, an avocado tree uses just as much water as a mulched lawn on equal area.
The ability of the soil to hold water differs according to its type. Sandy ground requires a different mode of watering than clay soil. Young plants require more care than the older.
Too much watering is a dangerous risk. It tends to flood the trees despite good plans. A common mistake is giving too much water to avocado plants, which can create serious troubles.
If one removes the extra water from the soil, a weak avocado tree can recover quickly and benifit much more.
For avocado trees in jars, the rules change a bit. A small avocado in a 5-gallon jar, that does not receive direct sunlight, does fine with half a cup of water every 9 days. Because plants in a big jar stay indoors, once weekly watering usually works.
The secret is to pour water until it covers the surface and allow it to fully spill through the drain. Drip watering works well for avocado trees in most situations.
The watering should depend on the real needs of the tree, not on a fixed plan. Check the soil to control if the tree thirsts, that is the most effective method. In winter, after some inches of reign, avocado trees only require extra water during a long dry period lasting two weeks.
Healthy growth and fruit making relate to sunlight, which requires the trees to get six to eight hours of sunshine daily.
On a big level, the farming of avocados uses huge amounts of water. Around 9.5 billions of liters are used daily to produce avocados in the whole world. That matches 3,800 Olympic swimming pools each day.
In certain areas, 320 liters of water are needed to grow only one avocado. In California, around 74 gallons are used for one single avocado. In Mexico, heavy avocado farming causes lack of water and drains underground reservoirs.
To grow an avocado tree to full size and fruiting, several years with muchwater must pass, so it is not an easy or fast cause.
