Many home gardeners experience tomatoes with green interiors at some point. But there’s no need to worry. Green tomatoes are perfectly safe to eat, even if the inside is still green.
In this article, we’ll explain why some tomatoes stay green inside, when they are safe to eat, and how to enjoy tomatoes at all stages of ripeness. Keep reading for the full scoop on green tomatoes!
Why Are Some Tomatoes Green Inside?
Seeing green tomatoes is common, especially with heirloom varieties. So what causes green interiors? There are a few reasons tomatoes can stay green on the inside:
1. Immature Tomatoes
Green tomatoes simply mean the fruit hasn’t fully ripened. The inner gel and seeds contain chlorophyll, which gives them the green pigment. As tomatoes ripen, carotenoids like lycopene turn the flesh red, but the inner core takes longer to lose its green hue
If your tomatoes were picked too early, they didn’t have time to fully mature and turn red throughout Give them a few more days to a week to ripen off the vine.
2. Cool Temperatures
Tomatoes need warm weather to properly ripen. Nighttime temperatures below 55°F or prolonged cool spells can interrupt ripening and cause green sections inside red tomatoes.
Once daytime highs reach 75-85°F again the existing tomatoes will resume ripening. Protect plants with row covers to keep the interior temperature warmer if cool weather persists.
3. Excess Nitrogen
Too much nitrogen fertilizer leads to vigorous foliage growth but poor fruit ripening in tomatoes. The chorophyll stays abundant, keeping tomatoes green inside.
Cut back on nitrogen inputs and the tomatoes should redden up. Always follow fertilizer labels and don’t overfeed tomatoes.
4. Low Potassium
Potassium (K) deficiency can also cause uneven ripening in tomato fruits. Low potassium impacts lycopene synthesis, leaving tomatoes green on the inside.
Supplement with a potassium-rich fertilizer or add wood ashes to the soil to correct the deficiency and improve ripening.
5.Varietal Characteristics
Some heirloom and hybrid tomatoes are just prone to green interiors, even when fully ripe. Green Zebra and Cherokee Green tomatoes will always have green flesh inside due to their genetics.
If the variety is meant to have green undertones inside, enjoy the unique color! It’s not underripe at all.
How to Tell if Green Tomatoes Are Ripe
Unless you’re growing a variety that stays green when mature, it can be tricky to discern if green interior tomatoes are actually ripe or not. Here are a few ways to gauge ripeness:
- Look for external color change – The skin should be fully colored and glossy. Green undertones indicate underripe fruits.
- Check for softness – Ripe tomatoes yield to gentle pressure. Underripe fruits are very firm.
- Watch for ease of separation – Tomatoes that are ready pull off the vine easily. Unripe tomatoes require force to remove.
- Sniff for aroma – Ripe tomatoes smell sweet and flavorful. Green tomatoes have little scent.
- Taste test – Bite a small piece. Ripe tomatoes taste rich and sweet. Unripe ones are bland or sour.
Trust all your senses. When in doubt, wait a few more days to allow full ripening. The tomato’s skin provides a good indicator of when the inside is ready to eat.
Are Green Tomatoes Safe to Eat?
Green tomatoes get a bad reputation, but they are perfectly edible even before fully ripening. Both green and red tomatoes belong to the same species – Solanum lycopersicum. The key difference is ripeness, not safety.
As long as the tomato is free from mold, rot, or other defects, it is safe to consume regardless of interior color. Some people even prefer the sharper tang of green tomatoes.
