I live in So. Ca. how often should you water tomato plants?
Question:The local nursery said I should water once a week because my tomatoes devoloped a disease on the bottom and said I was over watering them
Answers:
The nursery is right. Bottom rot is caused from over watering.
Water them often enough to keep the soil moist. If this requires more than once a week then do it. If you have low humidity, the water will evaporate faster. Use some mulch around the plants. That will help keep the moisture in. I use the clippings from my lawn. Works great and is "cheap".
well than there is your answer...why are you asking us?
Blossom end rot is likely the culprit of your tomato problem. The lack of magnesium from the leaching of water causes this development.
I add a tablespoon of Epsom salts to the soil, careful to avoid contact with the stem, and work it into the soil.
Water twice a week with the equivalent of 1-inch of rain, preferably with a soaker hose, about 20-30 minutes at a time. The fruits of the tomato do not get "pithy" from too much water and will develop a good flavor.
A low, nitrogen- based fertilizer once a month will help also. Too much nitrogen ( the first number of the 5-10-10 formula) and you will develop an abundance of leaves.
depends on the temperature and drought conditions,i would give a good watering at least twice a week or more depending on the temperature
