Trellis Netting for Training Vegetable Plants Professionally
Trellis Netting used as Vegetable Crop Support, increases Yields and reduces Plant Stress and Pathogens.
HORTOMALLAS trellis netting will provides so many advantages against the usual and traditional raffia twine support system. Plants will develop fully on a mesh net as compared to how much they can grow on a single string of raffia twine. Also aeration will improve as the leaves will be better and more efficiently exposed to the sun. Plants trellised on HORTOMALLAS net will not need to be touched as much to be guided and trained upwards as with other plant training methods. As we will discuss below, the less a plant is touched the more profitable the crop will be.
With HORTOMALLAS the horticulturist can adopt a hands-free trellising technique. This takes advantage of the plant´s nature and ability to climb freely searching for a support that will increase foliage airflow and maximize solar exposure (especially when using a double wall system like in the case of most solanaceae like tomatoes, peppers or eggplants)
Trellis Netting reduces the mechanical transmission of diseases.
By reducing physical (mechanical) contact with the field operators (besides reducing labor costs) you will reduce pathogens substantially, as virus and fungal contagions from plant to plant due to the actions of laborers will be eliminated since the net substitutes the manual training of the vegetable plant. Let´s remember that besides white flies and thrips, also the hands of the workers can become very harmful vectors of disease transmission.
Why is mechanical stress an important factor when trellising plants?
Also introducing trellis netting as a vegetable support system will reduce the handling of plants otherwise necessary during the manual tutoring using a raffia twine, and thus will reduce the mechanical stress to the plant, condition under which the plant stops producing fruits weight in order to re-establish its proper orientation towards the sun.
We have a study available that shows how mechanical stress from workers handling reduces crop yields by 8 to 10%. The explanation is very simple, plants are very efficient organisms: each leaf is turning towards the sun in order to maximize solar exposure. By having to handle plants and their leaf systems manually during plant training and tutoring, we are changing the orientation of the leaves stressing its natural functioning, thereby forcing the plant to draw from and use its energy reserves to rearrange the leaves towards the sun again. These 4-7 days needed to redirect leaves are days that the plant stops filling fruits. As the plant stops working at peak performance we are effectively reducing production by at least 1/10. Using a double walled trellis netting on the contrary, avoids these losses. If you are interested in this study, please send us an e-mail and we will gladly forward it to you.

Double Wall Trellising System ideal for Solanaceas.
In the double wall system of installing trellis netting it is important to note that the two sides of HORTOMALLAS net installed on each side of the plants´row must be slightly tightened at the bottom or foot of the plant. This is done since when the recently transplanted plant from the nursery tray into the soil or growing medium (in case of a hydroponic crop), needs a little bit of extra attention and support. As the plant grows upwards and thickens in order to support more weight the netting is allowed to open up and increase in distance as to support a wider and larger plant.
