Every gardener growing tomatoes waits for that first juicy, fresh, off-the-vine bite.
Tomato plants need full sun, orcloser to eight hours consistently every day,through all growth stages.
When your tomatoes refuse to turn red, they could be getting too little sun.

What is Full Sun?
Later,not enough lightproduces straggly weak vines and small, poor-quality fruits.

This is called the vegetative stage and may be a little shorter or longer depending on variety.
Vines grow rapidly and use a lot of nutrients.
In this stage light energy supports flowering and fruit set.

Small fruits start to form between 70 and 100 days depending on variety.
Six hours of light is adequate and eight hours can boost fruit production.
Ripening Stage
Temperature becomes more important during the ripening phase about 30 days after fruit appears.
Lycopene and carotene are pigments that give tomatoes their red color.
Why Morning and Afternoon Light Is Crucial
Morning and afternoon light are both important for tomato growth.
In the morning, the sun is high overhead, shining directly on the garden.
At noon it reaches its highest point during daylight hours.
This is when it is strongest, producing the greatest amount of energy.
Morning light is important because it dries dew, decreases nutrient loss through evaporation, and initiates photosynthesis.
Afternoon sun exposure extends the daily energy and growth cycle, giving tomatoes the sunlight quantity they need.
It can also create problems due to high humidity or dry soil.
Tomatoes need both morning and afternoon sun and at least six hours of sun a day.
Morning sun is important because it starts photosynthesis.
Afternoon sun maintains energy needed for healthy growth.
Tomatoes need a minimum of six hours of bright, direct sun.
Anything less yields weak or stunted vines with poor fruit development and reduced harvests.
There are certain tomato varieties that will grow in shade, though harvests may be smaller.
These include cherry or grape tomatoes, Golden sweet tomatoes and hybrids like the Juliet red tomato.
