How to Quickly Ripen Green Tomatoes

In autumn, tomato plants begin to slow down and any fruit they hold that hasn’t matured is unlikely to ripen on its own. Luckily, there is a simple way to quickly ripen tomatoes at home…

Late Maturing Tomato Plants

In an ideal world, you want your tomatoes to ripen naturally.  That’s the whole point of growing your own right? Understandably, that isn’t always the case. To get the results you want, sometimes you have to take matters into your own hands.

But before tackling how you can easily ripen your tomatoes, it’s worth figuring out how to prevent slow maturing plants and fruits in the first place:

Start Growing Early

This almost goes without saying but we feel it’s still important to stress. If you hope to harvest tomatoes at a specific time, try to start growing them as early as possible.

For example, tomatoes can be sown anywhere between February and April. If you’re wanting an August harvest, sow tomato seeds succinctly from early February to April. This way you give yourself the potential benefit of an extended growing period, allowing time for slow maturing fruits to ‘catch up’.

Focus on Plant Development

Make sure you put enough effort into feeding your plant enough to promote the development of fruit. We suggest using a premium quality tomato feed during the early stages of the plant’s life to boost its nutrient uptake and natural strength against diseases. This way, all the plant’s energy and focus will be on the producing plump and healthy tomatoes. rather than surviving.

Put plenty of time and effort into ensuring the plants were properly fed and watered to maintain development.

It’s time to try this handy hack to get your tomatoes ripened in as little as 7 days!

  2. Place them in a paper bag with a ripe yellow banana
  3. Make sure the bag is slightly breathable but can be closed securely
  4. Keep the paper bag in a dry place, indoors or in a greenhouse at a temperature above 10°C 
  5. After 24 and 72 hours, check the bag to see the progress. Your tomatoes might have completely ripened already. If not…
  6. Periodically check the bag to see the progress.
  7. Given a good 7 days, your tomatoes will be ripe and red-y to eat!

How Banana Ethylene Gas Ripens Tomatoes

Ethylene is a gas commonly known as the ripening hormone among the gardening community. That’s because it’s notorious for its ability to change the appearance of certain fruits as they ripen, such as bananas.

Unfortunately, tomatoes are not among the fruits which benefit from producing this gas, however, they are most definitely affected by it.

When in proximity to this gas or fruit that produces this gas, green to amber tomatoes also experience the ripening effect of ethylene.
