Why tomatoes not ripening

We just turn a sprinkler on after the sun is down if you get a lot of rain, you might not want to do this, but otherwise, the overhead watering allows the plants to cool off after a hot day.

My tomatoes mature to full size and stay hard as a rock? Is it something to do with the soil? I have tried less plants, less water, and they are in a raised bed in perfect sunlight? Do you always grow the same variety, or different varieties? Different varieties have different textures and perform differently under the same growing conditions. Have you done a soil test? Temperature fluctuations and over-fertilization can also cause problems.

I have 2 grape tomatoes plants —one I had out side and it has tomatoes forming on it. The other is about in my green house and is 5ft tall but has noting forming on it, it gets flowers but they dry up —I check to make sure it has water and it does. What is the problem? High temps will also cause blossoms not to set. My greenhouse tomatoes started setting fruit sooner than the ones in the garden, but once the temps got warmer, they stopped setting fruit because the temps in the greenhouse were too hot.

I heard there is artificial pollination tricks. Do you know about any? You can also use a powered toothbrush to vibrate them gently.

That was very interesting as i have been using a cotton bud to wipe the flower then going to another and wiping that flower. Just started so waiting for results. I will try the shaking and flicking. I use feather like a brush on tomatoe flowers and then use it to massage on branches and leaves of the plant. Yup, the finger-flicking method seems to work fine when I do it. I flicked my flowers several times in the last two weeks and most of them are growing tomatoes now.

One way to help with pollination is to gently shake the plants when there is a light breeze on a sunny day when the plants are producing more pollen. It worked great for my single plant growing in a crate.

My kids are dying to start eating them ha! Just pick the tomatoes that are at full size but not turning red, and leave the others to reach full growth. All I have to offer for troubleshooting is in the post. Large fruited tomatoes do generally take a long time to mature. Do you have any suggestions on how to get rid of blight from your garden, We have been gardening for over 36 years now and last year got blight on our tomatoes loose every tomato plant, this year we knew what to watch for and had a battle with it.

Is there some to do to prepare the soil for next year? If you have any suggestions at all we would appreciate them. Thank you for your time. What sort of blight, and where are you located? In the north cold climates , late blight should freeze out in most winters. Typical recommendations for organic gardeners are cleaning up and disposing offsite all plant debris at the end of the season to reduce the number of organisms overwintering.

Healthy, vigorously growing plants are much more resistant to disease organisms. The neighbors here with me support the nearby nursery. We all got verticillium wilt the same summer from the same tomato plants bought there. The wilt destroys the arteries from the root to the stems—the very delivery system that keeps the plant alive. The fifth year, I discarded the wood structure in the raised bed, discarded the soil, and bought new soil and used blocks instead of wood.

My plants are the healthiest, prettiest ever and the tomatoes are beautiful. After 4 years of disgust, I have tomatoes. Now, I must say I have contaminated soil where I moved plants around the house to grow as many tomatoes as possible against the house. These spots killed 2 dwarf lilacs, 2 rose bushes, a butterfly bush, a boxwood, and almost killed a peach ornament before I removed it and it is living now. Good luck. If you know you have blight in the soil, start spraying about a week after you plant.

You can also burn the blight out of the soil. Burning is allowed in our city, so we pile and burn our dead plants in the garden at the end of the season. This will kill the blight. If you can stand to go without the affected area, stake down regular black trash bags in the soil and leave it for months. The heat will kill off the blight. We stripped and made love in the middle of the tomatoes. Good love, enough to make the tomatoes blush.

With-in two days they were on their way being ready to pick; they turned faster than any year before once they started. She swore by it and that also works. For the second year in a row, I am discovering that someone has been vandalizing my tomato plants. Last year, my first and experimental gardening year, I grew my tomato plants from seeds. This year, I bought a small caged planter which was ripening some cherry tomatoes a day when suddenly no more ripening is occurring.

There are some 40 beautiful green tomatoes which are growing in size, but no coloration. There is everything needed in the soil, and ambient temps with plenty of rain and good drainage. It is resort style living and is very safe. The first time I noticed it last year, it was about mid season and the plants never bore another fruit. This time, it took a few days after their normal Wednesday grass cutting before I noticed it. The shaved areas began turning to the color of hay so it took time to show up.

It caused some of the branches to start turning yellow, so I immediately trimmed any yellow leaves and removed the dying branches as I identified them. I used masking tape to save a few flowering stems and that worked because these stems developed small callouses but survived and are now beginning to flower and bear fruit and new leaves.

It seems that the lower stems are still thriving and flowering, but the rest of the plant, at the shaved upper portion, though still supporting these beautiful green cherry tomatoes has been affected by the tomato bandit. All I can say is that he must hate me for some reason unbeknownst to me. It is a Hispanic Crew and I have been kind and generous in occasionally offering cold drinks. I realize these guys have had experience with farming and know secrets of raising or discreetly sabotaging plant yields that is par for the course with farming.

I have tried to do the research on how to save my plants and jump start their ripening process, but I have found very little info. I usually am around when the landscapers come around, but they arrived and cut very early the last time. I will take my plants in the nite before from now on, but I am thoroughly disgusted!

The guy laughed it off. I guess it was just a cruel joke to them… To get my tomato plants to ripen, I used water with epsom salt and molasses to feed the plants for a few days. In about a week, they started turning red again. I used to live in Memphis.. I can understand this happening.. Memphis has a hate vibe.. Lived a lot of places… such a beautiful city,???? Thank you, I have been worrying about my tomatoes. Our cucumbers, green beans, peppers, and pumpkins have been doing well.

Also, we have some tomatoes with blossom rot which I never heard of either so I will have to add some calcium to the soil. If you think your tomatoes are full size, you might try picking a couple and bringing them inside to ripen. A thick layer of mulch will also help moderate soil temp. I just started my garden this year in south Florida.

I know this may sound like a stupid question, but when can you tell if your tomato is at full size? I have Bonnie original and also Bonnie better bush. I have one tomato the size of a tennis ball, however it is still green.

Please advise. Thank you. Mature tomato size will vary with type and conditions. You can check the packaging or online listing for expected size at maturity to get a rough estimate, but patience and familiarity with a variety are the most reliable ways to know for sure.

You could stick an apple in the bag to try and give it some color, or have a fried green tomato. They always did well. This year I planted in another small garden with intense sun all day.

Although the tomatoes are great in size they are not totally ripening on the vine. Could the intense sun also be causing sun burn on the tomatoes? The weather this year was tough on crops in many areas. HI, i tried vigorously flicking and shaking my tomatoes but they refuse to pollinate? Are you familiar with how pollination works? Pollen has to move fro the stamen to the stigma, then down the pistol to the ovule.

You might try gently brushing those bright little clusters of pollen from one blossom to the next using a small paint brush. Think bees and butterflies, and their little feet passing from flower to flower. I had two types of tomato disease this summer. That one always hits my ROMAs. The second one was a black spot that climbed up the stem of the plant, leaving healthy foliage above and brown below. All the tomatoes that I picked then had brown spots that expanded until the fruit burst leaving a brown foul smelling liquid.

Anybody know what it is? And what to do? Large tomatoes take longer to turn red. Please read the article to see if any of the conditions apply. Odds are you just need to be patient. Laurie, This site is awesome! My tomatos are awesome as well!

Thank you, we live in Maine. Glad your tomatoes are doing well. Hopefully next year will be better! Hi Laurie. Seeing some of these issues here in our Harrisburg PA garden as well. I had 4 plants in the soil and have gotten only 6 zukes.

Also thinking of adding mushroom soil and some peat moss or sand to lighten up the current garden soil. Any thoughts? Have you done a full soil test, or only pH? Generally speaking, more organic matter is good for every soil. The same thing happens when you pinch off the flowers. The amount of water that a tomato plant needs depends on where it is in the growth cycle. During periods of rapid grow, the plant will wilt quickly if there is a lack of water.

However, when the temperatures are higher, the plant growth slows and the need for water also reduces. You can use this to your advantage when you are trying to encourage tomatoes to turn red.

My tomato plant had quite a few yellow leaves, so it makes sense to prune these so the plant can send its energy to the healthy leaves. It is a good idea to check your plant regularly to see if there are any yellowed leaves, or leaves with mold or spots on them. Remove these as soon as possible after you spot them. And if you are trying to ripen tomatoes on the vine, be on a special look-out for diseased leaves.

You will help the plant send its energy into turning the tomatoes red, rather than fighting off diseases. It is hard for me to throw away any tomatoes from my plants, but that is just what I did today.

The plant will now be able to focus on ripening the larger tomatoes that have reached the mature green stage. It is not just diseased leaves that should be pruned to encourage tomato ripening. Pruning some of the healthy leaves also helps the tomatoes to ripen more quickly, too. If your plant is full of healthy green leaves, and you are trying to get the tomatoes to ripen more quickly on the vine, then trimming off the vigorous growth will help.

Note: you should never cut off all the leaves. Removing them entirely is never a good idea, even when you are at the end of the season.

Trimming off some healthy leaves also improves air flow, which helps to keep fruits and the plant from being infected with diseases. If you have a heavy crop that is still on the vine but fall is fast approaching, pick a few of the tomatoes that are turning pink to allow the rest to ripen more quickly on the vine.

Bring in the almost ripe tomatoes and place them on a sunny window sill or in a brown paper bag on the counter.

If cooler temperatures are expected in your area, you can cover your tomato plants to keep the plants in the ideal temperature range and allow the fruit to continue ripening. Covering the plants with row covers also does the opposite to bring down the temperature in hot climates, as noted above.

As odd as it sounds, one of my readers suggested pulling slightly on the root ball can encourage fruit to ripen. It is thought that shifting the root ball distributes the nutrients and moisture from the root to the fruit and leaves causing the plant to finish ripening fruit and go to seed.

This is something we tried this year but I have not had a chance to see if this helps to turn tomatoes red, but would appreciate any feedback from readers if it has worked for you. What if fall is approaching and you have tried all of the tips for ripening tomatoes on the vine and the fruit is still green? You can pull out the entire plant and hang it upside down in a garage, greenhouse, or shed where it will be protected from the elements and cooler weather.

You can even bring branches of green tomatoes indoors to let them ripen by hanging upside down, although this can be a messy process. The warmer the spot where you hang the t0mato vines, the quicker the fruit will ripen. Most of the fruit on the plant will ripen, except for the very newest fruit that has set on the plant. Also, if you end up with more green tomatoes than you can handle, a good used for them is to make fried green tomatoes.

Six weeks before your expected first frost is the time to maximize your tomato harvest. If you put these tips into practice at the right time, you will allow your plant to focus the energy on ripening fruit instead of producing more leaves and immature fruit.

I share your thought about not wanting to let my garden's bounty go to waste! I have been dehydrating foods for over 30 years, and just recently discovered that my husband will eat dried tomatoes like they are candy!

He loves to grab a small handful on-the-go. I use grape tomatoes for full flavor, and since they are now in full production, I can pick them every day and not let any go to waste. Slice them in half, place them on the dehydrator tray, lightly salt and pepper them, and in they go at degrees for about 5 hours. Hi Randy.
