Will water on my tomato plant's leaves burn them?

Question

Hi, I was wondering if it was bad to get water on a tomato plant's leaves when watering them in the morning? Some of my plant's leaves appear to be a bit burned, and I was wondering if it was maybe because I got water on them. Conversely, is it actually good for the plant to get water on the leaves, especially on a hot day? (I'm thinking like evaporation = cooling effect as it does for animals). Thank you thank you!

Answer 1

Each time it rains and the sun comes out the leaves are wet and do not get burned.  The burned by sun's magnification is a wives's tale.  

More likely you've got salt in your water that might be causing problems.  

Burned or pitted leaves are common especially near the end of the growing cycle.  You've had a season of hit-and-run bugs such as leaf hoppers stopping by for a sip through the leaves.  

Sports fields have been known to turn on sprinklers to cool the turf just as you were with the tomatoes.  But you needed worry about the tomatoes.  They are semi tropical and love warmth.......up to a point.  You'd be better off providing a light shade covering...cheese cloth awning...to cool the plants.  Plus that tiny bit of shade discourages those dastardly leafhoppers from dining.

yea  

Answer 3

Not unless you water then in  midday when the sun is shining directly on them.  Water in the early morning or in the evening.  And try to avoid getting water on the leaves by soaking the ground around the plants.

Answer 4

Yes, the sun burns them through the water droplets. Just water around the base of the plant in the early a.m. or eve.! Go ahead and pull off the dead leaves, and it should perk back up : )

Answer 5

The idea that watering is bad for plants when the sun is shinning was dreamed up by someone with way too much time on their hands. I have heard these same people say watering at night kills plants. When exactly will these people who never farmed in their lives going to water?

What are you going to do if it rains?  Hold an umbrella over all your grass, trees, plants and flowers? The only two effects of watering during the hotter part of the day are your plants get water and it evaporates faster due to the heat.

Hot dry spots on the leaves are more likely from a pest having taken a bite to see if it likes tomato plants and moved on to your roses.  

Spray as your water bill can handle.

Answer 6

DO NOT put water on your tomato plant's leaves in the morning.  By doing so you are actually allowing the sun to cook your plant.  If you put water on the leaves, I would suggest doing so in the evening, when the sun is almost down.  If you water your plants in the morning, do so before the sun is up very high, and don't water the leaves, try to get just the roots.  :) (:

Answer 8

U should water them at night because if you don't these water droplets combined with the sun causes your leaves to burn the same way a magnifying glass and the sun's heat causes things to burn!!

Answer 9

Tomatoes can handle water on the leaves - easily, hon. After all... plants love rain, you know? But if you have any fertilizer in the water, the fertilizer IN the water can burn the leaves.

Sometimes leaves will just die in response to sun or too little or too much water, etc. If it's just a couple at a time, don't worry about them.

As for watering in high heat days - I sometimes water the soil just a little bit - so the roots get a little drink and can rehydrate the plant a little. It is better overall to water when it is early morning or late evening so the plant can take full advantage of the water it receives.

Good luck with your tomatoes!

Peace.

Answer 10

no, on a hot day-that is when they are most likely to get burned...you should always try to get water to the roots as this is the main way they get food, and the leaves are for photosynthesis...so if its in the morning, it shouldnt matter too much if you get the leaves wet, but i would definitely try not too in the afternoon
