Crop Netting in a Greenhouse and Outdoors
High density planting is possible with HORTOMALLAS® trellis netting
Hortomallas makes available this excellent introductory article about trellising to support vegetables using crop netting in a greenhouse or outdoors. Trellising vegetables, with growing netting, support the plants in an upright position and the heavy load when high-yielding varieties or hybrids.
Keeping the foliage and fruits up off the ground reduces the incidence of plant disease and improves the quality. HORTOMALLAS® trellis netting keeping plants off the ground avoiding disease and damage also increasing the productive life of the plant.
What does the trellising of vegetables aim to do?
A trellis using crop netting in a greenhouse or outdoors allows for high planting densities. When planted at a high density of having greater yield. The stems are not as rigid as when planted at a lower density. Trellising the crop, the main stalk is reinforce so that it can bear the weight of the crop.
Trellising is appropriate for high-yielding plants. When using high-yielding varieties or hybrids, the quantity and weight is necessary to reinforce the stem using trellising. A case in point was the planting of sweet peppers that stood up to the weight given that they were small and thin-walled.
A good mound of earth was sufficient for keeping the plant upright. It became imperative to provide support for the plants to be able to stand up to the high yield of heavy, thick-walled fruits. Without support, broken stems from excessively heavy fruit was common.
Trellising improves fruit quality.
Cucumbers, can be grown on the ground, if appear a light-green spot where the fruit touches the soil, the value will decrease.
This leaves one with no other choice than to trellis in order to have a quality product.
Keeping the fruits up off the ground, there is a lower incidence of plant diseases which discolor and blemish.
Trellising makes it possible to grow a crop certain times of the year when it would otherwise not be possible.
During rainy seasons or when there is the risk of rainfall, trellising tomatoes becomes obligatory in order to avoid diseases.
Such as Alternaria stem canker, gray leaf spot, and buckeye rot of tomato,
To mention just a few, as well as various fruit rots caused by fungus and bacteria which decreases commercial value.
Trellising increases production in greenhouses
Reducing the presence of diseases, growing crops in greenhouses demands the use of trellising, because cost of greenhouses is high.
In addition to use surface area to the greatest advantage also use the air space.
Melons grow on the ground in Spain greenhouses due to the lack of labor but not in Latin American countries.
Trellising generates rural employment
Vegetables are labor intensive primarily because of the need for pruning and training to a trellis. Tomatoes requires more labor than a crop of cabbage because of the need for pruning and training to a trellis.
In the state of California, tomatoes are grown spread out on the ground with mechanize planting and harvest.
This results in the lowest cost tomato in the world in spite of being one of the countries with the highest cost of labor in the world.
Trellising techniques
In the case of yam and green beans and other climbing one way of trellising with minimal costs for a small landholder. Let the plants entwine themselves on a crop of corn which is plant as a companion with the purpose of climb up the corn stalks.
Wooden poles, metal pipes, and even concrete posts get use outdoors to support other crops. Inside professionally designed greenhouses, the mechanical design took into account wind and rain loads as well as the weight of a crop.
For this reason, the greenhouse itself can be the support for crop netting in a greenhouse.
In homemade greenhouses the support for the crop is usually independent of the structure since the structure is usually weaker. The trellises support wires or cables to which the crops attach themselves. In the state of Lara in Venezuela, small horizontal canes are often use instead of wire to support the crop.
To tie up the crop, cord is use that can be make of plastic strands, with or without UV protection, or it can be make of natural fibers from plants of the agavaceous family.
Passion fruit and grapes can be grow on arbors which have crisscrossing horizontal wires on top, as is do in the southern zone of the Maracaibo lake in Venezuela.
The vertical trellis technique is being use since yields are greater and it allows for the mechanical harvesting of the crop. In the case of grapes, all new plantings using current methods are now do with vertical trellising with several wires. In order to tie up tomato plants various pieces of twine are use, and each branch tied to the trellis. Any excess of stems is prune in order to allow for air circulation in the crop.
The same technique is use for sweet peppers in zones such as the departments of Santander in Colombia and the state of Tachira in Venezuela.
As a reference, we cite the experience we acquired during our time of service of providing technical assistance in Mesa de los Morenos and the town of La Grita, each of these towns being located in the above-mentioned fellow Latin American countries, respectively.
In greenhouses, pieces of twine is use to tie the base of the stem which spirals around whatever the support for the plant. Lateral branches are reduce to leave only two or three horizontal branches per plant. This technique is use for tomatoes, sweet peppers, melons, and cucumbers, to mention just a few examples.

When grown outdoors, sweet peppers get enclose between two vertical panels of trellising are then support between the two panels. Lateral growth is restrict by neighboring plants. We also used this technique successfully in the case of eggplants. Flowers, such as carnations, chrysanthemums, like to grow up through horizontally placed and allows the plant to grow straight up. Straight stems are necessary for quality flowers in the national and international markets. Roses, they get trellis in a way similar to sweet peppers, with wire and the stakes and the same spacing of one meter (40 inches).
Crop netting in a greenhouse or outdoors for trellising
We will do a special article about crop netting in a greenhouse and outdoors. This netting provides so many benefits for the crop and labor savings. We have used it for tomatoes, sweet peppers, yams, pumpkins, passion fruit, cucumber, gherkins, and climbing green beans. The crop of passion fruit reduces the amount of time until harvest and for sweet peppers and tomatoes, cuts the labor required in half.
