Topping tomatoes simply means cutting the top off. Remember that indeterminate tomatoes will continue to grow and produce fruit if you keep them healthy and supply them with support. That is true unless you cut the tops off because tomatoes grow and develop new leaves from the top.
The good news is that all is not lost. In the very least, a new central leader will emerge and become the new main stem. Tomatoes are notorious for producing lots of “sucker” stems throughout the season, so you can count on something taking over for the lost main stem.
Cutting the tips of tomato vines stops the growth on that vine. This process of "topping" tomatoes can increase tomato production and provide control over plant growth. Commonly done at the end of the growing season, simple pinching and pruning is all it takes to top tomatoes and improve tomato harvests. (Vid.
You can actually create new tomato plants with these clippings! Simply throw them into a glass of water or a soil medium for a week or two, then they'll be ready to be transplanted. However, since it's going to freeze in a month or so, it doesn't make sense to transplant these outdoors.
If the stem tip of the plant is cut, apical growth of the plant stops growing. Lateral buds start growing due to which branches are formed.
This means pinching out the growing tips at the top of the plant and stop the plant growing up any further. Stop off at the top of the plant when there are 3-4 (outside grown) and 4-5 (greenhouse grown) trusses, which are layers of flowers.
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.
Prune off about a third of the leaves (and flowers, if any are present) at the top of the plant, removing the newest, smallest leaves. This will stimulate the plant to branch out lower on the stem, and eventually to produce flowers and fruit throughout its height.
Only indeterminate tomatoes benefit from topping. If you top a determinate tomato, you'll likely miss out on some of the potential yield. Knowing which type of tomato you've planted also helps with spacing and caging or staking needs.
Most people are familiar with growing new plants from seeds, but new plants can also be created by cutting off a portion of an established plant. This “cutting” is placed in an environment that encourages it to produce new roots and/or stems, thus forming a new, independent plant.
Called "topping," this type of pruning causes the plant to stop flowering and setting new fruit, and instead directs all sugars to the remaining fruit. This way, the fruit will ripen faster, plus it becomes more likely that the green tomatoes you pick before frost will actually ripen when you bring them indoors.
Absolutely saveable, if you've been quick enough. Plenty of support and light will do the trick. Masking tape is my go to, it's strong enough when wrapped and gentle enough remove without damaging the stem further. I'd also take a few cuttings and start propagating just in case.
Is it possible to overcome tomato wilt? The answer to this is, if it's caused by an environmental factor – yes, you can recover your plant. However, if the plant is wilting because of a pathogen, it is unfortunately, almost always necessary to uproot and destroy the plant.
The plants grow quite tall in summer and I often notice bunches of green tomatoes that I know won't ripen in time. That's when I cut the top off the tomato plants. This is a great way to keep the plant from growing even larger and instead ripening the fruits. I cut them when they grow to around my shoulder.
Water correctly: Do not overwater. The first week tomato plants are in the ground, they need water every day, but back off watering after the first week, slowly weaning the plants down to 1 to 1.5 inches of water per week.
Every two weeks, prune the lower leaves on the vine, removing about a third of the plant's leaves. Instead of pruning the suckers, you want to prune away non-producing stems and leaves so that the plant can focus on lots of fruit production.
Tomato plants require approximately 1 inch of water per week. Plants may wilt badly when soils are dry, but will revive rapidly when they are watered. A thorough watering once a week during hot, dry weather should be sufficient.
Perfect Tomato Growing Conditions
Tomatoes love the sunshine. A position in full sun (that means an average of at least eight hours a day) gives the best results in most areas, though if you're in a hot climate you can get away with dappled shade.
If an established, or larger plant becomes leggy, then they can often be saved by pruning them well and pinching the top off the plant. This encourages the plant to grow bushier and put its energy into something other than growing tall.
Pruning. If the crown of your tree is stretching too tall or wide, corrective pruning can help rein it in and size it down for the space available. It's crucial to prune a tree before it becomes a problem because taking away too many branches could cause unnecessary stress.
Some gardeners recommend you “pinch off” the flowers on your tomato transplants during their first weeks of growth, claiming that removing early blossoms: Directs more energy into establishing a strong root system. Results in a larger, sturdier, and potentially healthier tomato plant.
