How often should I water this grapefruit tree?

slithytove(9)October 13, 2007

My new apartment has a grapefruit tree. It's about 15 feet tall and pretty scrawny. The landlady says nobody's cared for it at all in quite some time. She said it'd be nice if I took care of it, and suggested watering it twice a week, but that sounds pretty excessive to me...

I live in the SF bay area; the temperature rarely gets above 80 degrees, and there's usually some moisture in the air. I'd be inclined to give it a really deep watering once a month... Does that sound right?

The best thing you can do is get to know the tree in its environment. The humidity in your area should be a plus. Outside trees can be watered every 5 to 14 days depending on the climate at the time. The whole thing is don't keep the ground around the tree soggy all the time - citrus rootballs need air as well as water. When you water it, soak it and then let it get fairly dry before watering again.

When temps are high and evaporation is quick (spring and summer), water more around every 4 to 6 days. If temps are lower and less evaporation occurs - more around the 10 to 14 days. Texas A&M has a great site on outdoor citrus care.

How about if you change the word 'water' in the above (very good) posting to 'check'? Watering should never be thought of as a calender event, but taken care of on an as needed basis.

Drenching frequency can vary widely, depending entirely upon the vigor of the plant, kind of plant, kind of container, size of the container in relation to the plant, temperature, relative humidity, kind of potting medium, condition of root system, time of year, sunlight, and MORE! ;-)

It's important, too, to water thoroughly each time, and then let the soil begin the drying cycle all over again.
