the shoots that form in the axils where side branches meet the stem. Remove suckers when they're small by pinching them off or snipping them with pruners.

What happens if you don't prune tomatoes?
Unpruned foliage will eventually grow into new branches that will form fruit, but most experienced growers advise that tomatoes should be pruned to not only produce larger fruit earlier in the season but also to protect the plants against pests and disease problems.
Can tomato plants get too much sun?
Tomato Sunscald: Why Too Much Sun Can Be Hazardous to Your Tomatoes' Health. Tomato sunscald is a problem caused by growing conditions – specifically intense, direct sunlight for extended periods during very hot weather. The excessive sunlight discolors patches on ripening or green tomatoes.

What are the signs of over watering tomato plants?
Early signs of overwatering in tomato plants include cracked fruit and blisters or bumps on the lower leaves. If the overwatering continues, the bumps or blisters on the leaves turn corky. Meanwhile, the roots begin to drown, die and rot, which reduces the amount of water the green part of the plant receives.
Why am I not getting tomatoes on my plants?
Insufficient Pollination
Tomatoes are self-fertile, which means each flower can pollinate itself. Nevertheless, the presence of bees and/or wind dramatically improves pollination by nudging the flowers just enough to help dislodge the pollen from the stamens.
Why are my tomato blossoms drying up?
When flower stems turn yellow and the flowers dry up and fall off, this is known as “blossom drop.” In tomatoes, the primary reason why this can occur is temperatures that are either too cold or too hot. Tomatoes prefer daytime temperatures of 70 to 85o degrees.
Does tomato flower does not need to be pollinated?
Tomatoes are self-pollinating, meaning they have flowers that contain both the male and female parts, so more than one plant is not needed for reproduction. The pollen falls within the flower to pollinate itself. That doesn't mean insects and wind aren't important, though.
Do tomato plants like morning or afternoon sun?
No matter where they live, tomatoes, roses and other disease prone plants always want morning sun; the sooner the sun strikes their leaves in the am, the faster the dew will evaporate and the healthier the plants will be.
Do tomatoes grow better in shade or sun?

When should I pinch my tomato plants?
Pinching seedlings back when they are 4 to 6 inches tall to force new growth works for any tomato plant. Because the plant is young and has not yet bloomed, this does not affect fruit set. Plants can be pinched again as soon as new growth grows 2 to 3 inches, if necessary.
How can you tell if a tomato plant is determinate or indeterminate?
Look at the branching formation on your plants. If the branches are long with sparse foliage, they are likely indeterminate. A compact, bushy plant is determinate because it form flowers at the terminal end of the branch, which signals the stem to stop growing.
