Trimming or cutting away dead parts of the plant or new shoots to encourage lateral branching.
Pruning is a standard practice in indoor crops where we want crops to go up. In the solanaceae we maintain 1 – 3 stems. In cucurbitaceae usually a single stem. It can also be applied in open field. In addition we also refer to pruning when removing leaves for increasing the ventilation in the crop.
Pruning results in:
earlier production
increase in fruit weight
easier to work in when spaying or harvesting as well more ventilation which will reduce humidity related diseases. Leafpruning can start when the fourth cluster is setting.
Leaves that turn yellow and dry out need to be removed as well.
Snapping, rather than cutting off leaves gives in general a better healing of the wound.
Do not remove foliage above the lowest cluster as it is needed for assimilation.
The best time to pick leaves is early morning, with dry weather, a few hours after the first irrigation. Leaves will break easily, avoiding big wounds and those wounds can dry quickly.
Never defoliate too much in one time to maintain the balance between the rootsystem and the evaporating surface.
Spray preventive after every leaf-pruning in humid conditions.
1. controls size of the plant,
2. avoids spread of disease,
3. encourages lateral branching,
4. improves size and quality of fruits,
5. makes management of crops becomes easy
6. improves light and air circulation within plant.
Pruning is done based on purpose for uniform length of branches/ vines and to get bigger fruits in watermelon
Cut the shoot tip after the 4-5 leaf
Leave 3 vines per plant
the fourth or fifth bud
Remove branches inside to ease monitoring and treatment
Keep 2 minor branch on 1st floor.
Then 2 for branches 4, 6, 8.
1. Use clean and sharp scissor 2. Bring collecting pail with you 3. Dispose pruned parts properly 4. Avoid pruning during wet condition
