Growing Tomatoes in Indirect Light – Answered!

How to Grow Tomatoes in Indirect Light

You’ve probably wondered if your tomatoes will still grow in shady spots. The quick answer is yes, they will!

With that out of the way, we’ve got answers to some of the most burning questions for growing tomatoes when it comes to sunlight needs. Curious? Let’s start!

Do tomato plants need direct sunlight?

Tomatoes can be harmed when exposed to too much sun. Though tomato plants flourish in abundant sunlight, they can encounter challenges if subjected to excessively high temperatures and intense sunlight for prolonged periods. 

Extremely hot and arid conditions, particularly without sufficient watering and proper care, may result in dropped blossoms, sunscald affecting the fruits, and even wilting of the plant.

There are numerous conditions that happen if tomatoes don’t get enough sun. They may stretch out with fragile stems and limited fruit yield. 

Scarcity of sunlight can also lead to subpar fruit development, delayed ripening, and heightened vulnerability to diseases. Inadequate sunlight compromises the overall well-being and productivity of tomato plants.

Is 4 hours of sun enough for tomatoes?

No, 4 hours of sun is not enough for tomatoes, especially when you want to grow them for their fruits. Tomato plants need 6 to 8 hours of direct sunlight. 

However, they could potentially grow with only 4 hours of sun exposure. In this condition, their growth and fruiting might be stunted. 

If you’re faced with limited sunlight availability, think about using reflective surfaces to optimize the available light.

Is 6 hours of sun enough for tomatoes?

Yes, 6 hours of sun is enough for tomatoes. While they might not be as sturdy as those getting more sunlight, you can still make the most of this light level. 

Choose tomato varieties that mature early, make sure the soil drains well, and maintain regular watering and feeding for optimal results.

Yes, you can grow tomatoes in shaded areas. But this doesn’t mean they’ll be healthy or produce their delicious fruits!

Tomato plants thrive exceptionally well with optimal sunlight. Without it, their productivity tends to suffer. 

Remember, they are not shade-tolerant so they prefer around 6 to 8 hours or more of direct sunlight daily. But if you’ve got only shaded parts to grow, don’t worry – we’ve got solutions for that!

We’ve listed some of our recommended shade-tolerant tomato varieties. Here’s a quick look!

Beefsteaks, great for sandwiches, mature slower than smaller tomatoes. For cool, foggy areas, try the heirloom Russian “Black Krim” variety. 

They usually mature in 75 days. Though less sun means lighter color, it still yields tasty fruit.

Looking for patio and apartment gardening? Grape, pear, and cherry tomatoes are well-suited for these places plus they fruit quickly!

They tend to thrive in shaded spots early and late in the season. Go for the disease-resistant “Black Cherry”, maturing in 65 to 75 days.

Got plenty of room? Try the German heirloom ‘Blondkopfchen,’ a yellow fruit in about 75 days. 

Limited light? Consider the red ‘Stupice,’ cold-tolerant and flavorful, producing in 52 to 65 days.

Versatile paste tomatoes are perfect for salads, canning, or sauce. Opt for Mama Leone in foggy or dimly lit areas.

Can I grow tomatoes in partial shade?

Yes, you can grow tomatoes in partial shade. Here’s what you need to know: there are different light intensities when it comes to partial shade.

These include light during mornings, middays, and afternoons. Let’s check each variant, shall we?

Morning sunlight is less intense than the others. The good thing is that it still provides high-intensity light to tomato plants without excess heat. 

Midday sunlight, between 12 p.m. and 2 p.m., is the brightest but the hottest. It’s this intensity that sometimes requires protection for your tomato plants.

Noonday sunlight can be scorching and intense. At this point, you’ll need shade to reduce stress on the plants.

Afternoon sunlight, less intense than midday, is beneficial to tomato plants. This is a bit better, especially in places with rising temperatures. 

It starts after 2 p.m. and is the second-best sunlight for growing tomatoes. But don’t be fooled!

In the late afternoon, the sunlight can still be quite hot. It’s a good idea to let other plants provide shade for your tomatoes once they’ve received their required sunlight earlier in the day.

Also, the intensity of the sun’s rays depends on your location. If it’s possible to lightly shade your plants in the strong afternoon sun, that would be your best bet.

Try to go for a mix of morning and late afternoon sun to avoid harsh midday scorching. This safeguards against sunburn while ensuring adequate sunlight.

What are the results of tomatoes growing without direct sunlight?

The results of tomatoes growing without direct sunlight are reduced slower growth, reduced fruit production, longer maturity time, smaller and fewer fruits, weaker plants, paler leaves, leggy growth, and reduced flavor.

Let’s go over each end result briefly, alright? 

Slower Growth

Tomatoes need sufficient sunlight for proper growth. Without enough light, they may grow slower and look spindly or elongated as they reach for light.

Reduced Fruit Production

Limited sunlight can restrict the flower and fruit count in tomatoes. They need sunlight for photosynthesis to create sugars and support fruit development.

Longer Time to Maturity

With reduced sunlight, tomatoes may take longer to mature and ripen. This could lead you to experience delayed harvests.

Smaller and Fewer Fruits

Fruits produced in low-light conditions might be smaller in size and fewer in number. This is of course, when compared to similar varieties grown in full sunlight.

Weaker Plants

Tomatoes grown in inadequate light might become weaker. Weakened plants tend to be more susceptible to diseases and pests.

Pale Foliage

The leaves of the plants might appear pale or yellowish. This can indicate potential nutrient deficiencies caused by reduced photosynthesis.

Leggy Growth

In an attempt to reach for more light, the tomato plants might develop elongated stems. This growth pattern can make them less sturdy and more prone to bending or breaking.

Reduced Fruit Flavor

There is a possibility that tomatoes grown in low-light conditions might have less intense flavor. Again, this is compared to those grown in optimal sunlight.

Tomatoes that get intense sunlight can develop sunburn, heat stress, soil dehydration, uneven ripening, flower drop, reduced fruit sweetness, and blossom end rot.

Keep in mind that intense sunlight occurs from noon until the afternoon. Even if your tomatoes receive indirect light in the morning, they can still be affected if fully exposed during these hours.

Similar to humans, tomatoes can also suffer from sunburn. If they are exposed to intense, direct sunlight for extended periods, their leaves and fruits may develop sunburned patches. 

These discolored areas might turn white, yellow, or brown, and can potentially lead to tissue damage. You don’t want that in your tomatoes, do you?

Heat Stress

Intense sunlight raises plant temperature, causing heat stress in tomatoes. Leaves may wilt, droop, or even curl up without warning! 

In severe cases, signs of stress even include stunted growth and reduced fruit production.

Soil Dehydration

The sun can dry out soil fast. This makes your tomatoes thirsty and weak. 

You can end up with plant roots that struggle to get enough water. And you don’t want that in a plant that’s already receiving low light!

Uneven Ripening

Too much sunlight means uneven ripening. Some parts of the fruit ripen faster, making the whole fruit ripen unevenly. 

This makes the ripeness unbalanced and the fruit taste flat.

Flower Drop

High temps and strong sunlight are tomato enemies! They can make flowers fall off before fruit forms. 

This means less fruit for you, which is bad news when you’ve put in so much effort!

Reduced Fruit Sweetness

Lots of sunlight leads to more sugar in leaves. The plant then sends sugar away from fruits. 

As a result, fruits become less sweet and bland. And what’s the point of growing tasteless and flavorless tomatoes?

Blossom End Rot

One of the most dreaded issues when growing tomatoes! Did you know that heat and high light can cause it?

The dark sunken spots make fruit inedible. While sunlight isn’t the main cause, it’s still part of the problem.

While high levels of light are ideal, you can still grow tomatoes even if your area is less than perfect. We’ve got a foolproof way for this!

How to Grow Tomatoes Under Low-Light Conditions
1. Choose the right tomato varieties.
Choose shade-tolerant tomato varieties like “patio” or “determinate.” These are more compact and can handle lower light levels better.
2. Pick the right spot.
Put tomatoes where there’s indirect light. South-facing windows, bright balconies, or areas with filtered light work great.
3. Avoid overcrowding.
Give tomato plants space. To do this, follow the spacing guidelines on the packet label of the seeds. 
4. Use reflective surfaces. 
Use aluminum foil or white surfaces to reflect and amplify light for the plants.
5. Consider artificial lighting. 
When natural light is scarce, add artificial lighting as a supplement. Special plant grow lights offer the right spectrum for healthy growth. 
Place the lights 6 to 12 inches above the plants. If possible, keep them on for 12 to 16 hours daily.
6. Prune and train your plants. 
Make sure to prune and train tomato plants. This helps energy go to the main stems and fruit. Remove extra leaves that block light from the lower parts.
Pruning also improves airflow. This prevents fungal diseases in low-light areas.
7. Optimize your soil quality and watering. 
Encourage healthy roots with good, quality soil. The soil should drain well and be rich in nutrients. 
Just keep the soil moist, but not waterlogged. Simply water the plants adequately and regularly to achieve this.
8. Mulch to conserve moisture.
You can apply organic mulch at the plant base. Mulch is great at keeping the soil moist and regulating its temperature.
9. Protect from extreme weather.
Protect your plants from extreme weather with cloches and other forms of protection. Excessive heat or cold can add more stress, especially in low-light situations.
10. Fertilize appropriately.
Use balanced fertilizer to give plants essential nutrients. But don’t over-fertilize as it can cause more leaves and fewer fruits.
11. Be patient, observe, and adjust accordingly. 
Know that tomato plants in low-light conditions mature slower and fruit later. Watch their progress closely and adjust care accordingly.

Planter’s Tips

Indirect sunlight works for basic plant growth, but it’s not as intense as direct sunlight. We suggest going for bright, filtered light in the area throughout most of the day.

Ideally, the total daily light should be at least 6 hours. Honestly, more light is even better.

Growing tomatoes in indirect sunlight relies on your location and climate. Regions with milder temperatures and longer growing seasons have better chances of success.
