How To Grow Cherry Tomatoes Indoors – In The Winter!

Did you know that you can enjoy growing and harvesting cherry tomatoes indoors all winter long?

Cherry tomatoes are one of the most popular vegetable choices to grow for home gardeners. Not only can you get a huge harvest from just a few plants, they also produce much faster than their larger slicing counterparts. And are they ever good!

Cherry tomatoes are perfect for eating fresh in salads or for adding to salsas, juice, and sauces. And with so many different cherry tomato varieties available on the market today, there are near endless options when it comes to color and flavor.

They might be little, but there is nothing small about the flavor and excitement of enjoying fresh cherry tomatoes all year long!

While it is quite difficult to grow larger slicing tomato inside, cherry tomatoes are actually the perfect size and shape for growing inside year-round. And since they also happen to be self-fertilizing, there is no worry about the need for pollinators like bees and butterflies to find your plants.

In fact, all you really need for indoor tomato growing success is a warm room, a little bit of light and a few tomato seeds – and you’re ready to grow!

How To Grow Cherry Tomatoes Indoors

Selecting The Best Variety To Grow

When growing cherry tomato indoors, success all starts with selecting a variety that is well suited to small spaces.

It’s best when growing indoors to look for varieties that are labeled as being “patio” or “container” friendly. There are also newer dwarf type cherry tomatoes that are even smaller and perfect for indoor growing. (For specific varieties to grow, we included a few great selection at end of the article to try)

All of these “smaller” types are usually much more compact and don’t need large containers to grow extensive roots. Their smaller plant size makes them perfect to sit on shelves or in any space where the lighting is just right.

What You Need To Start Cherry Tomato Seeds Indoors

In order to grow tomatoes indoors, you will need a few basic supplies beyond your seeds, including potting soil, a good container or pot – and depending on the lighting in your house, an inexpensive fluorescent or LED shop light.

Selecting Your Potting Soil

Just as if you were growing tomatoes outdoors, you need to have good soil to produce great plants. The soil needs to be light, airy, and retain moisture well.

A good all purpose potting soil is great for this, especially if you add in some additional worm castings and coffee grounds to the mix. These help to add even more energy to the soil to help plants reach their full potential and yields.

Since you are growing indoors in smaller containers, you can start your seeds right in the final growing container. This eliminates the need for transplanting and keeps the seedlings growing fast. See: How To Create The Best Potting Soil For Potted Plants – The Perfect Potting Soil Recipe!

Choosing The Right Container – How To Grow Cherry Tomatoes Indoors

When selecting your pot or container, it’s first important to make sure it has plenty of holes for drainage. Poor drainage can lead to the roots becoming waterlogged. For indoor plants, and especially tomato plants, that can spell big trouble.

You can find LED and fluorescent lights in all kinds of shapes and sizes. These lights are perfect for providing the additional light tomatoes need to grow.

As for size, if the cherry tomato plant is less than a foot tall at its mature height, a container of around 6 to 8 inches in diameter and at least 4 to 6 inches in depth is ideal.

For larger cherry tomato varieties, aim for a final container that is at least 12 inches in diameter and 8 to 10 inches in depth. The larger you can go, the better as it will allow for a more extensive root system to develop.

Lighting Requirements – How To Grow Cherry Tomatoes Indoors

When growing tomatoes indoors, lighting is usually the biggest key of all. Tomato plants require at least 6 to 8 hours of direct daily light in order to grow healthy and strong. They will still grow with less light, but not as well – and certainly not as productively.

You can grow tomatoes in a sunny, southern facing window. But in most cases, it’s far better to give your indoor tomatoes a dose of daily artificial light to really get them to produce.

The good news – it doesn’t have to be fancy, expensive or hard to do. There is no need to purchase expensive grow lights. Tomatoes do not require a special spectrum of light to grow, which means ordinary fluorescent or LED lights will work perfectly fine.

To use, keep the lights a few inches above the tomato plants at all times. Leave the lights on for around 12 to 14 hours each day. If you are supplementing window light, adding 4 to 6 hours of artificial light will help.

Unfortunately, using only window light will usually leave plants leggy and thin. It’s better to use a combination of both if possible – as it will lead to better overall plant growth.

When your plants are growing in window light, always make sure to rotate the plants so all sides of the plant get sufficient light. When using overhead artificial light, all that is necessary is to keep the lights overhead. 

Water, Fertilization & Pollination – How To Grow Cherry Tomatoes Indoors

So how do you keep indoor tomatoes growing strong? The first key is to water smart. It’s best to keep the soil of your growing cherry tomato plants moist but not overly saturated. Only water after the top two inches of soil is dry to touch. 

Tomatoes are heavy feeders, so be sure to give your indoor plants half a dose of all-purpose liquid fertilizer every two weeks. As an alternative, you can apply compost tea or worm casting tea weekly for a more natural, slow-release fertilizer option. 

As mentioned earlier in the article, cherry tomato plants are self pollinating so they do not require pollinators such as bees and butterflies. Outdoors, they rely on wind and even the flapping wings of wasps, bees and butterflies to spread pollen. But indoors, it’s easy to mimic this quite easily in order to help them out.

The first method to help pollination is to add an oscillating fan to the growing space. This helps to move pollen around, and just a few hours a day of a fan will work wonders. You can also gently shake the plant every day when there are blooms present.

Lastly, you can also hand pollinate to help transfer pollen from one flower to another. All methods will work, and it really comes to down to finding the one that is easiest and most effective for you.

As with all tomato plants – whether grown indoors or outside – harvest the fruit often to keep plants producing as long as possible.

Harvest Early And Often – How To Grow Cherry Tomatoes Indoors

The best way to encourage your plant to keep producing cherry tomatoes when growing indoors (or anywhere for that matter) is to harvest the fruit early and often. 

Thankfully, with indoor growing, you don’t have to worry about pests, bugs, or most diseases ruining your plants or tomatoes. But harvesting the tomatoes regularly will still help in overall production. Not only will it let you enjoy fresh cherry tomatoes right away, it also helps to encourage plants to send resources to produce new blooms for future fruit more quickly.

When it comes to overall harvest, the type of plant you are growing matters. If you are growing an indeterminate variety of tomato, it will continue to produce as long as you keep watering and fertilizing. Determinate varieties will produce most of their crop all at once and then begin to die off.

So what are some of the best varieties of cherry tomatoes to grow indoors? Luckily – we just happen to list 6 of the best of the best below!
