Why Are My Tomatoes Not Growing? Exploring Possible Causes and Solutions for Stunted Growth
Why Are My Tomatoes Not Growing?
There are several reasons why your tomatoes may not be growing.
Firstly, high temperatures can prevent tomatoes from ripening properly, as temperatures over 85°F can hinder the production of pigments responsible for ripe tomato color.
Additionally, overfertilizing tomatoes with nitrogen-rich products can divert energy away from ripening fruit.
If your tomatoes have suitable temperatures and fertilizer levels, but still aren’t ripening, it could be because there are too many fruits on the plant.
Removing some fruits can help the remaining ones ripen faster.
Moreover, different types of tomatoes have different ripening times, with cherry tomatoes generally ripening faster than larger heirloom varieties.
Finally, if fall arrives and temperatures consistently stay below 50°F, tomatoes will not ripen on the vine.
However, partially green tomatoes can still be ripened indoors.
Placing them in an area with a temperature of 60 to 65°F or in a paper bag with an apple or banana can speed up the ripening process.
Alternatively, uprooting the whole tomato plant and hanging it upside down indoors can allow the tomatoes to ripen on the vine as the plant dies.
Key Points:
- High temperatures over 85°F can hinder tomato ripening.
- Overfertilizing with nitrogen-rich products diverts energy from ripening fruit.
- Too many fruits on the plant can prevent proper ripening.
- Removing some fruits can help the remaining ones ripen faster.
- Different types of tomatoes have different ripening times.
- Temeratures below 50°F in the fall prevent tomatoes from ripening on the vine.
Did You Know?
1. Did you know that tomatoes are actually a member of the nightshade family, along with potatoes, eggplants, and peppers? This means that if you’re experiencing issues growing tomatoes, it’s worth considering the overall health and conditions of your nightshade plants as a whole.
2. Tomato plants are one of the few plants that are self-pollinating, meaning they have both male and female reproductive organs in each flower. However, they can still benefit from the assistance of insects or wind for optimal pollination, which can lead to improved fruit production.
3. In some cases, stunted growth or lack of fruit production in tomato plants can be attributed to excessive nitrogen in the soil. While nitrogen is essential for plant development, an excess can cause the plant to focus on leafy growth rather than fruit production.
4. Adding crushed eggshells to the soil around tomato plants can help provide them with the necessary calcium they need for healthy growth. This can prevent disorders like blossom end rot, where the bottoms of the fruits may become black or rotted due to calcium deficiency.
5. Tomatoes are considered to be a warm-season crop, and they typically require temperatures above 50°F (10°C) to grow successfully. If your tomatoes are not growing, it could be due to cold temperatures or erratic weather conditions, especially during the early stages of growth. Providing a protective cover or moving containers indoors during cool spells might help overcome this issue.
Temperature And Tomato Ripening
Tomatoes are well-known for their love of warmth, which is why they are primarily grown during the spring and summer months. However, when temperatures become too high, it can impede the ripening process. The ideal temperature range for tomato ripening is between 68 and 77°F. In this temperature range, tomatoes produce the necessary pigments responsible for their vibrant, ripe color.
When the mercury rises above 85°F, the production of these pigments is hindered. This means that even if your tomatoes have reached their mature size, they may fail to turn red or fully ripen. Instead, they may remain stubbornly green. This phenomenon occurs because high temperatures cause a metabolic slowdown in tomatoes, decelerating the ripening process and preventing the development of the characteristic coloration.
To mitigate the impact of excessive heat on tomato ripening, gardeners can take several precautions.
- Providing shade to tomato plants using shade cloth or umbrellas can help to regulate the temperature and prevent excessive exposure to direct sunlight.
- Watering the plants during cooler times of the day, such as in the early morning or late evening, can help regulate soil temperature and keep the plants hydrated without overheating.
- Ensuring that there is proper air circulation around the plants can also help in maintaining a suitable microclimate for ripening tomatoes.
Effects Of Overfertilizing On Tomato Ripening
Fertilizing tomato plants is essential for their growth and development, as it provides them with the necessary nutrients to thrive. However, overfertilization, particularly with nitrogen-rich products, can have detrimental effects on the ripening process. The overabundance of nitrogen diverts energy away from the ripening fruit, instead promoting excessive vegetative growth. This can result in lush, green foliage but delayed or inhibited fruit ripening.
When nitrogen levels are too high, tomato plants focus their energy on producing more leaves and stems rather than diverting resources to the development and ripening of the fruit. This imbalance can significantly slow down the ripening process, leaving gardeners frustrated with underripe or immature tomatoes.
To prevent overfertilization and promote optimal tomato ripening, it is crucial to follow recommended fertilization practices. Testing the soil and using a balanced fertilizer specifically formulated for tomatoes can help ensure that the plants receive adequate nutrients without an overabundance of nitrogen. Monitoring the plant’s growth and adjusting fertilization accordingly can also prevent overfertilization and promote healthy, timely ripening.

Too Many Tomatoes, Slow Ripening
When it comes to tomato plants, it is natural to want a bountiful harvest. However, an excessive number of tomatoes on a single plant can lead to slower ripening. This is because the plant’s resources are divided among the numerous fruits, inevitably prolonging the ripening process for each individual tomato.
To address this issue, thinning or removing some of the fruits can help speed up ripening. Identifying which fruits are likely to ripen faster and selectively removing some of the slower-growing tomatoes can redirect the plant’s energy to the remaining fruits. This way, the nutrients and energy can be focused on a smaller number of tomatoes, accelerating their ripening process.
While it may be difficult to remove promising tomatoes, particularly after investing time and effort into cultivating them, thinning the fruits ensures a higher quality harvest in the long run. By allowing fewer fruits to reach maturity, gardeners can enjoy a more concentrated and timely ripening experience.
Variations In Tomato Ripening Times
It is important to note that not all tomatoes ripen at the same rate. Different varieties, sizes, and colors can exhibit variations in ripening times. Generally, cherry tomatoes tend to mature and ripen at a faster pace compared to larger heirloom varieties, which require more time to fully ripen.
Understanding the specific ripening times of the tomato cultivars you are growing can help manage expectations and plan accordingly. Gardeners should research and select tomato varieties that are suited for their specific climate and desired harvest time. By doing so, they can ensure that the tomatoes they are growing align with their timeline and preferences.
Furthermore, planting a mix of early-ripening and late-ripening tomato varieties can create a more extended and diverse harvest season. This approach offers gardeners a continuous supply of fresh tomatoes, ensuring that they have ripe fruits available for consumption throughout the entire growing season.
Ripening Tomatoes Indoors: Methods And Techniques
When temperatures drop and the growing season ends, tomatoes may struggle to ripen on the vine. However, all hope is not lost. Even partially green tomatoes with slight coloration at the blossom end can be ripened after harvesting.
One of the most common methods for ripening tomatoes indoors involves placing them in an area with a temperature range of 60 to 65°F. This can be achieved by utilizing spaces such as a pantry or basement. Unlike the misconception that tomatoes require sunlight to ripen, they actually rely on the natural ripening gas called ethylene. By placing the tomatoes in a paper bag alongside an apple or banana, which release ethylene gas, the ripening process can be expedited.
Another technique for indoor ripening involves uprooting the entire tomato plant and hanging it upside down. As the plant gradually dies off, the tomatoes will ripen on the vine. To ensure success, remove as much soil as possible from the roots before bringing the plant indoors. This method is particularly effective for potted tomato plants as they can be easily moved indoors and placed in a sunny spot until the remaining fruits reach maturity.
By utilizing these indoor ripening methods and techniques, gardeners can extend the tomato harvest and enjoy the full flavor of ripe, homegrown tomatoes even after the outdoor growing season has come to a close.
