Tomatoes reach their peak harvest times between the months of July and September, but there are a couple of options when it comes to the optimal time to pick these juicy, sweet veggies. Ideally, they can be harvested at their prime or earlier, as they are capable of ripening after picking.
Tomatoes come in an array of flavors and colors that range from reds, oranges and yellows, greens, and even striped. To figure out when to pick tomatoes it is crucial to know what varieties you are growing and their peak hue so that you can get the most out of your high producing plants.
You can expect to begin your tomato harvest when plants have grown for 70-90 days, and the temperatures hover between 70 and 80 degrees Fahrenheit. Tomatoes start ripening from the blossom bottom of the fruit, so that is one of the prime indicators that your tomatoes are beginning to ripen and a key to what color they will be. As tomatoes change to their peak colors, look for smooth, soft, glossy skin and uniform color that yields a bit when gently pressed with your fingertips.
Leave tomatoes on the vine as long as possible to achieve their desired level of ripeness. When you surmise that your tomato is ready to pick, twist fruits off of the vine individually. Check your tomato plants daily and harvest their fruits continually. If you pick them a bit too early, they can be left on the counter to ripen further. You can also place them in a paper bag; stem pointed upward with an apple. This will speed up the ripening process.
As the season begins to come to a close and the weather starts to get cooler, you may want to prune off less developed tomatoes from the vine and sacrifice them for the more mature ones. Less developed fruits will not have sufficient time to develop fully, so it is beneficial to take them off. This pushes energy back into the plant and its more mature fruit, producing more substantial late-season beauties.
With so many varieties of tomatoes to choose from, it can be hard to decide which to grow. Explore and try different types and determine what kind of tomatoes suit your needs and your tastes. Here are a few of our favorite tomato varieties to get you started as you bring tomatoes from farm to table this season.

- ‘Brandywine’ produces a large, meaty tomato and boasts a beautiful pink tone. They are great tasting and act as fantastic sandwich slicing tomatoes.
- ‘Mr. Stripey’ has a unique and colorful look to its fruit, and its unique striations of color make this variety a conversational showstopper in the garden.
- ‘Beefsteak’ tomatoes are classic tomatoes that grow to over a pound of juicy meaty flesh. They are standard garden tomatoes and can be found readily in garden centers. Keep in mind that their large size may make them prone to splitting on the vine.

I’m an early farmer, and lost a lemondrop tomato plant, by transplanting it so it wouldn’t be close to my beefsteak, it died, will it be to late ( June 25, 2020) to plant another?
Hi Josef! It depends on your hardiness zone. Tomatoes take 40-60 days, depending on the variety, to produce harvestable fruit and they like warm weather and sun. Can you maintain the optimal growing environment for them for the entire time they need? Starting from seed might be too late but perhaps a clipping or a young plant. If you have a greenhouse of course that helps too. You can find your planting zone here: https://www.kellogggarden.com/blog/gardening/how-to-find-your-planting-zone/
Can I mix the kellogg garden organics tomato vegetable and herb fertilizer with water to use as a spray to help prevent blossom end rot? Or will it damage the plant leaves?
Hi Shelly! You can make a fertilizer tea for your plant and spray your plants. Here is a post to walk you through it. https://www.kellogggarden.com/blog/how-to-make-fertilizer-tea/
What tomato varieties would you recommend to grow in a greenhouse over the winter? I’m in zone 8.
Hi Sonja, when growing tomatoes in a greenhouse over winter it’s crucial that your soil temperature remains at least 60 degrees Fahrenheit and that your tomatoes receive 6 to 8 hours of sunlight a day. If you’re unable to put them in a location that receives that amount of sunlight we recommend supplementing with grow lights. You’ll want to choose a variety that will grow great in containers, you can find some of our recommendations here, https://www.kellogggarden.com/blog/gardening/container-gardening/tips-and-tricks-for-container-gardening-tomatoes/ along with tips for growing tomatoes in containers. Happy gardening!
Hello. I am a new gardener. I tried to grow tomatoes but all I got was lots of greens and flowers, no tomatoes. I bought a bee barn, bee attractant and even tried to manually “pollinate” by applying an electric toothbrush near the flowers (as directed on one online article). I fertilized and watered as directed. I also sprayed the leaves with a diluted epsom salt, bicarbonate water mix with a bit of dish detergent as suggested online to keep pest, mildew away plus to prevent magnesium deficiency. The plants has about 6 hrs of sun per day. The tomato plants were planted in a new box garden about 24 inch deep with a mix of 50% top soil and 50% premium organic garden mix. What am I doing wrong?
Hi Chung, we’re so sorry to hear that your tomatoes plants did not fruit. When assisting your plants in pollination it’s important that you go from male to female flower. We recommend using a small paintbrush or a q-tip to transfer the pollen as an electric toothbrush can be a bit rough. Tomatoes need at least 6 hours of sun per day but giving them more is oftentimes a good idea. Lots of sun coupled with warm conditions will help them thrive and fruit. It’s good that you fertilized your plant but tomatoes are heavy feeders, therefore, it is recommended to fertilize them throughout the growing season. They are also heavy feeders on calcium and magnesium so try using a fertilizer that contains these nutrients or supplementing them separately.
It is difficult to determine what may have gone wrong without seeing photos of the plant. We recommend joining the Facebook group Organic Garden Nation, https://www.facebook.com/groups/organicgardennation. It’s a great community where beginning to advanced gardeners share tips, ask questions, and help one another with their gardens. There may be gardeners in the group who have experienced something similar or live in the same zone as you and can offer advice. If you’d like, we recommend posting a photo of your plants and describing the issues to the group. We can also take a look and offer more in-depth advice.
I noticed an unseasonable year of growing the larger variety of Tomato. I had no problem with the cherry variety. Any word or reason for this. I usually have NO problem with growing beefsteak tomatoes or other larger varieties. I’m in zone 10A San Diego CA.
Hi Renee, while it is difficult to determine the cause of your unseasonable tomato growth, it could be because it has been a hotter than average year in Southern California. Prolonged high temperatures can impact the growth and production of tomato plants significantly. The high heat also means your plants will require more water and with the stress possibly more nutrients. Your cherry tomatoes may have done better due to their location in the garden, how much water and nutrients they received, and if they’re a variety that thrives in hot conditions. We hope this helps, happy gardening!
I have slugs eating on my tomatoes and cantaloupes. How do I get rid of them???
Hi Elma, we’re sorry to hear about your plants. Slugs can be destructive and notoriously difficult to get rid of. Setting up beer traps has worked for some; the yeast attracts them, not the beer. If you Google slug beer trap, you will see ready-made traps or get ideas on how to build your own.
Slugs also dislike wool and copper. You can put down wool or wool pellets, or copper tape, or copper mesh. Finally, there are organic slug repellents that can help. Look for products that have iron phosphate as the main ingredient and the OMRI listing logo. Those products will not harm other insects or animals.
Slugs also dislike some herbs, so consider planting some mint, lavender, or sage nearby to deter them. For more information, check out this article, https://www.kellogggarden.com/blog/insect-pest-control/natural-ways-to-stop-slugs-snails-from-eating-plants/. We hope this helps!
I noticed you didn’t have a comment for Heirloom tomatoes as to when to pick them. This is my 2nd year growing them and because many of the heirloom varieties have green/brown/dark red colors to the skins, I still have trouble knowing WHEN they’re ripe. Can you advise please?
Hi Adrienne, using size and color to determine when to pick your tomatoes can make things a bit confusing at times. Heirlooms can be tricky because you don’t want to leave them on too long as they can split or crack, get picked off by critters, get sunscald, plus it can limit the number of tomatoes your plant will produce.
When harvesting, wait until the tomato is at the breaker stage. That is when it is just starting to change color (other than variations of green). Typically the color change starts at the bottom of the tomato, you will see pink or yellow, or brown starting to show. Anytime after this stage, you can pick the tomatoes, and they will ripen off the vine. If you store them stem side down and away from the direct sun, they will stay firm and ripen up nicely.
Another great way to check for ripeness is by squeezing the fruits. If they have a slight give when you squeeze them, they’re ready! To harvest heirlooms, always use two hands, one to hold the tomato and one to twist or cut the vine. This will reduce the risk of damage. Happy Harvesting!
