How much / often should I water my tomato plants?

It depends where you are (how often) and what kind of soil (how much). Assuming you have fairly good soil, you can try dauily watering. In Arizona I water mine daily. We use a drip tape that waters a few gallons per plant. One of the keys to watering tomato plants is to water consistently. Tomato plants do not like to dry out. Deep regular watering will prevent stress on both the plants and their fruit. You can lose one whole fruit set by letting the plants go dry just once. Inconsistent watering will also cause fruit cracking or dropping. A regular watering pattern is very important to tomatoes. When watering your tomatoes, be sure to water from the base - avoid overhead watering - it's a sure way to spread disease.


Check the soil by digging down a couple of inches to see if the soil is wet. You don't want it too wet either. I would water them daily - the same time of day.

Every evening, try to water them a couple hours before sunset and you should be fine. if the soil still looks moist, wait another day to water.
Reply:You can buy quite inexpensively a moisture testing meter that you can stick into the ground to see how moist the soil is at various depths. It can appear dry on the surface and yet be soaked a few inches down. Over watering is not a good idea. Another bad idea is watering late in the day or at night so that the foliage will be wet or damp all night. That will promote all the things plant developers have been trying to avoid: fungi, blights, molds, etc. The general rule is that you want to water early enough in the day for the foliage to dry before nighttime. Also, better to water thoroughly when you do than only sparingly but all the time. The roots will grow up towards the water and a hot sun will burn them. Soaking the plants later in the season will promote splitting, as the skins cannot expand quickly enough to accommodate the extra fluid.
Reply:if it is summer season there.water it twice a day..ie morning and evening..in other seasons once a day is enough.but if you water it twice it will be better and will yield better results..
Reply:You should water them everyday (unless it rains), and possibly twice a day (once in early morning, again in late afternoon) during periods of excessive heat and lack of rain.
Reply:3 times a day.
