The basics

How long does it take to ripen tomatoes

Tomatoes on average take 20 – 30 days for a flower to full size mature green tomato.

It can then take another 20 to 30 days on average to ripen.

Tomatoes need the right temperature to ripen. The best temperature to ripen tomatoes is between 68 -78 degrees. With temperatures less than 55 or more than 85 degrees, your tomatoes with stop ripening.

So what do you do if you don’t have 20 days of low 70-degree weather?

Remove unnecessary energy draws.

Start by removing any very small, immature fruit. There is little chance they will ripen but they will use up a lot of energy. Also remove suckers, flowers and some excess foliage. Be careful to leave enough foliage for the plant to still get energy from the sun.

Row covers or hoop house

You can keep the plant warmer by putting on a row cover or hoop house. This can be done fairly easily but simply putting clear plastic over the plants’ stakes. You can add a few taller stakes if you need them. Make sure your plants have room between the plastic and the leaves. No need to build anything complicated since it is very temporary. Regular clear 6 mil construction plastic will be fine for a temporary hoop house. If it rains make sure the water can runoff.

Cutting roots

You can also encourage the energy to go to fruit ripening if you cut the roots.

Your tomato plant will go into survival mode as the temperatures get cooler. Your plant will divert energy from fruit ripening to root growth. To stop the roots from growing, take a flat-ended shovel and cut into the soil around the plant about 6″ deep in a circle about 12″ from the plant.

This will redirect the energy to the fruit.

All of this will buy you time but if it gets too cold you may decide to pick the fruit and ripen indoors.

5) to speed the ripening you can put a banana in the box. If you don’t have a banana an apple will do just as well
