How to train and prune vine tomatoes?
Ndeterminate tomatoes, also known as vine tomatoes, have a long fruiting season, unlike bush tomatoes. However, they can be vigorous, producing a mass of leaves and stalks, frequently at the expense of good-sized fruit. Such crops are tough to control and susceptible to fungal disease. Limiting the plant to one or two powerful stems leads to fewer but larger fruit and healthier plants.
When grown in containers, vine tomatoes may be kept manageable by keeping a single major stem. In the backyard, two primary stems can be trained and encouraged by a trellis or frame.
I)Identify the principal stem/s and connect the stalks to a bet or onto a trellis at intervals over the length of the stem. The way of tying is vital. Use twine, not plastic or wire ties. First tie onto the supportthen loop the ties around the stem in a figure of eight and knot, so the stem isn’t tight against the aid.
II)Pinching out the side shoots can begin when the stem is 30cm high or abandoned before the stalks are longer. Break out each side shoot which appears between the primary stem and the leaf, otherwise these will develop into secondary stalks. Use your thumb and forefinger to break out the shoots, not a knife or secateurs since this may create a weakness which allows in illness.
III)If unwanted shoots have developed into stalks, cut off them using sharp secateurs or a knife, being careful not to damage the plant. Even if the stem has blossoms, it’s ideal to remove it.
IV)Assess the foundation of the plant and remove any stems that are sprouting out of there.
V)After the smallest truss of flowers starts to form fruit, then you can cut back the leaves below by a third or half, especially if they’re shading the fruit.
VI)When you feel that the blossom has produced enough trusses, you can stop it by cutting back into a leaf just above the upper truss. This will station the plant’s energy into ripening and swelling that the fruit.
Good to know
The very best fruit is generated along the key stem/s.
Plants generally begin to flower after six true leaves and the main stem continues to create trusses following every 3 — 4 leaves.
