The advantage in removing the lower leaves is that the plants energies go into producing fruit rather than a lot of foliage. Also the lower leaves tend to get powdery mildew so it is good to remove them to stop disease spreading.
There is no specific number of leaves to remove from a tomato plant. If you see a stem with no flowers on it, chop it off, it's useless. If you see a stem with three or four trusses you may want to sacrifice one or more of these trusses to ensure that more nutrients are getting to the remaining ones.
Removing leaves is a great way to speed up the growth of new tomatoes. I use this trick often for my plants outside. Removing some of the leaves will help the sun reach the tomatoes, and they will ripen faster. The plant will focus more energy on growing the tomatoes if you remove some of the leaves too.
With large-fruited tomato varieties such as ox-heart and beef tomatoes, however, the side shoots should be removed. Even with medium-sized indeterminate tomatoes, we recommend only leaving a maximum of two to three shoots, including the main shoot.
In order to speed up the ripening process, all you need to do is trap the ethene gas in with the tomatoes by putting them in a paper bag, cardboard box or empty kitchen drawer. Add a ripening banana or apple, which will also give off ethene to help things along.
Once a week, prune about a third of the plant's leaves, starting at the bottom of the plant and working your way up to the top. You can certainly prune less than a third of the leaves, but never do more—that's the golden rule of pruning a tomato (and any other plant).
Watering tomato plants every day will prevent them from developing a strong root system and sitting in wet soil is an invitation for root rot and other soilborne diseases. When you water, do not wet the plant leaves.
Tomatoes thrive in loamy soils with good drainage and high organic matter content. Adding composted coffee grounds to planting beds is a great way to build healthy soil for tomato planting but won't provide all the required nutrients.
Overwatering generally makes the plant look almost like it's rotting, as in drooping and turning soggy brown. My guess is it is having Nitrogen problems. Any type of vegetable fertilizer you buy at the store should work fine.
Tomato plants have big appetites and need a steady supply of plant food to grow their best. Miracle-Gro® Performance Organic® Edibles Plant Nutrition Granules feeds both your plants and the beneficial microbes in the soil (which help plants take up all the nutrition they need) for up to 6 weeks.
You may notice yellowing, wilting, spots between leaf veins, or blackened leaves. If the frost was mild and the plant's stem is still healthy, you can simply remove the damaged leaves and let the plant recover.
Overwatering tomatoes can lead to yellow and spotted leaves, while underwatering results in wilt and diseased fruit.
Some growers prefer to use a high-phosphorus fertilizer, indicated by a larger middle number. You can also keep things simple with a fertilizer especially formulated for tomatoes – usually with a ratio like 3-4-6 or 4-7-10. Most importantly, don't over-fertilize. Too little fertilizer is always better than too much.
What's most important is how the plant looks in the evening, after sunset. However, don't water until the next morning. If you water at night, the already wetter conditions and low temperatures can promote disease.
Also the lower leaves tend to get powdery mildew so it is good to remove them to stop disease spreading.
If you're wondering how to increase flowering in tomatoes, try increasing how much light they receive. Tomatoes need eight hours of daylight to flower. Sunlight gives your tomato plants the energy to produce fruit, so if your plant doesn't have enough sunlight, you're less likely to see tomatoes fruiting.
Make sure you remove more of the lower leaves but also remove some leaves growing higher on the plant, so that it stays open and airy. If you leave 6 to 7 adult leaves per plant, that will be fine.
If you're seeing a bit of red on those green tomatoes, picking them individually and bringing them inside may be the best chance for ripening tomatoes. Like many fruits, tomatoes continue to ripen once they've been picked.
Without proper sunlight, the tomato plant will have leggy and spindly growth and little or no fruits. To produce tomatoes the plant requires energy which they receive from sunlight. Therefore, place your plant where it will receive enough sunlight to produce juicy and plumpy tomatoes.
2. Breaker Stage. In the Breaker Stage, color will be visible at the blossom-end of the tomato skin and tomatoes are considered to be “vine ripe." The color change at the blossom end indicates the tomato is producing ethylene, a ripening agent produced by the plant.
