Why are My Tomato Plants Sweating??
Comments (4)Hi E., You are very observant. When plants 'sweat', it is known as transpiration. (When humans do it, it is known as 'perspiration'. lol) In plants, transpiration is a natural part of the process of photosynthesis. Most of the time, transpiration is a good thing. Transpiration is just the evaportation of moisture from the leaves of the plant. It occurs when a plant is conducting photosynthesis. The stomata of the leaves are open to allow the passage of CO2 and O2, and the water passes out of the stomato at the same time. As long as your relative humidity is lower than 100%, the air will dry the transpiration off the leaves. This is known, of course, as evaporation. Is evaporation the end of the process? Not quite. Plants, of course, need moisture, so they have to have a way to replace the moisture they lose via transpiration. So, to replace the water lost from their leaves, the roots of the plant take up more moisture from the ground. At the same time they are taking up water, they also take up minerals, which they use as nutrients. The plant uses the minerals as food, the moisture moves through the plant and is part of the process of photosynthesis and, at the right time, some of the moisture transpires out of the leaves and evaporates. It is an ongoing process. Where plants run into trouble is when there is a lack of available moisture in the soil and the roots cannot find any water to take up to serve as a replacement for the water that has transpired through the leaves. When there is no water available, the leaves wilt. A little wilting on a hot day can be normal, even with moist soil. It just means the plants are transpiring moisture out of their leaves faster than their plants can take up more moisture from the soil or that there is no moisture in the soil for uptake. However, with each plant there is a certain wilt point that it reaches from which it cannot recover and leaves or even the whole plant die. That's why we try to keep an even, steady supply of moisture in the soil for plants.....to prevent excessive wilting following transpirtation. Make sense?

Comments (10)Sorry, I forgot to post where I am which is zone 6. 1. Yes, I do see a lot of the lower leaves have soil build up on them. 2. Im not really sure why that part of the soil would be much different than the rest. I turned over and mixed that whole area a few weeks before planting. Should I try adding used coffee ground and/or egg shells around its base? 3. I had to start over after my first attempt. Something ate the plants when I planted them. Which is why there aren't as big as you would expect. 4.I know they would need a bigger pot to actually grow. I didn't give them much attention after I took the strong plants to put in the soil. Actually, didn't even expect them to grow at all with the way I left them in the pot. ( I actually have one growing in a pot with potting soil, that I believe is 5 gallon. That one was doing well. Now it is recovering from being over watered ) 5 The peppers wouldn't benefit from being spread out and put into soil, over only spreading them out in the pots? No, I am not using potting soil. Didn't know there was a difference and used garden soil. The only reason the tomato has potting soil, is because I planted it the pot from a fig tree I purchased. Thank you for the response...See MoreWhy are the blooms on my tomato plant dying and falling off?
Comments (0)What is going wrong? "Blossom-Drop" is a condition suffered by tomatoes, peppers, snap beans, and some other fruiting vegetables where the plant blooms but fails to set fruit, the blooms die and fall off. It may be caused by the use of excess nitrogen fertilizers or dry windy conditions, but the most common cause is temperature extremes. Tomatoes, peppers and beans are especially picky about the air temps when it comes time to set fruit. If the night temps fall below 55 or rise above 75 or if the day temps are above 90, the pollen becomes tacky and non-viable. Pollination cannot occur. If the bloom isn't pollinated, the bloom dies and falls off. What can I do? Water the plants deeply once a week, mulch heavily to maintain constant soil moisture levels, establish windbreaks as needed, avoid using excessive amounts of nitrogen fertilizers, and wait for temperatures to moderate and stabilize. Earlier timed planting can help attain fruit set prior to the on-set of high temps, and the use of protection can compensate for cool nights. Some recommend attempting hand-pollination with an artist brush or a gentle shaking of the plant/cage/support prior to the hottest part of the day will also help. Fruit set will resume when temperatures moderate. Hormone sprays, such as "Blossom Set", may prevent some blossom drop due to LOW temperatures. However, the resulting fruit are often misshapen. But studies prove that hormone sprays do not prevent blossom drop due to HIGH temperatures....See MoreWhy is part of my tomato plant wilting?
Comments (8)The stalk borers don't usually attack fruit. it's really common for fruitworm or other caterpillars to get inside fruit, though. Fruitworm moths usually lay their eggs around the calyx,and the baby fruitworms bore in under protection there, and the larger holes you see elsewhere in the fruit that look like perfect holes are usually their exit holes. If you're seeing a lot of those, start spraying BT up under the sepals of developing fruit. Caterpillars that attack from the outside in vs from the inside out usually don't leave deep holes but leave damage to the outer wall of the fruit. Next time you cut off a branch that looks like it might have a borer in it, split it lengthwise to see whether there's debris inside consistent with frass. Or you may even come across the borer. You probably know this already, but the borers that affect tomatoes (and corn and other plants) are dull brown/gray moths. They're not the same species that attack squash plants....See Moresoonergrandmom
