How to choose the right Support trellis net for your cultivation needs

Support trellis there are many varieties of vegetable and flower support systems; let’s see which one is the most suitable. We are already convinced of the economic benefits of reducing mechanical stress and the phytosanitary benefits of decreasing the spread of pathogens through crop netting. We realized that using plastic raffia and/or cotton threads is much more expensive due to the required labor. Now comes the most difficult part: choosing the right type of trellis net that you really need to start benefiting from.

There are basically three types of nets available in the market:

– **HORTOMALLAS**: Extruded polypropylene netting with 25x25cm squares.

– **HORTOFLOR® or MALLAJUANA**: Polypropylene netting with 15x17cm squares.

– **TRICOLOR**: Knotted net made from strong polyethylene cord, ideal for vertical vegetable crops.

– **SCROG**: Woven net without knots, made from nylon or polyester. Although it is the most expensive among all the options presented here, it features very smooth round threads that won’t damage plant stems. This last option is exclusively used by installing multiple horizontal layers over flower beds in cutting crop cultivation.

Various types of trellis nets from HORTOMALLAS® for different types of crops and needs.

The reason for the color of the trellis net

The common feature of these products is their white color (for better visibility during the early hours of the day when other colors are more prone to accidental cuts) and the addition of polymeric antioxidants against UV rays, which extends the field life of these nets.

Speaking of durability, the HORTOMALLA, HORTOFLOR®, and MALLAJUANA® trellis nets last for about 3 (or more) years in open fields with proper care and without exposure to agrochemicals that reduce their lifespan. The TRICOLOR®, being thinner (and more economical).

will last up to 18 months in open fields. The SCROG net will last between 18 and 24 months. When these products are used in shade houses or greenhouses, their lifespan can increase by up to 50% more.

Chemicals that reduce the lifespan of polypropylene nets: Support trellis

Chlorosulfonic acid and oleum, hydrochloric acid, hydrogen peroxide, sulfuric acid, nitric acid, liquid bromine, and any of their derivatives.

Some reduction in tensile strength and an increase in flexibility and elongation at the breaking point can be expected, depending on the nature and amount of absorbed organic material.

Which trellis net do I need for my vegetables:

TRELLISING TOMATOES: Depending on the planted variety, you need support on both sides, ranging from a meter in height for tomatillos to 2 meters for some semi-determinate varieties in open fields. For this crop, the extruded HORTOMALLAS® is available in heights of 1m, 1.5m, or 2m, with either 25x25cm squares (the most commonly used) or 15x17cm squares. Alternatively, tomatoes can be supported by using the net in multiple horizontal layers, allowing a part of the net to hang over the sides of the row to provide support for outward-growing plants.

Support trellis
Trellis net for tomatoes, HORTOMALLAS®, is primarily used similar to agricultural twine, on both sides of the plant. However, unlike twine, it doesn’t require as much expense for manual tying.

The TRICOLOR® net is also used for tomatoes in a similar manner to agricultural twine, on both sides of the plant. But unlike twine, it doesn’t require as much manual tying as the plant grows. This is because the net’s multiple squares help keep the plant in place.

As mentioned before, reducing plant-worker contact increases crop profitability. The plant doesn’t need to pause production for several days to readjust its foliage to face the sun for efficient photosynthesis.

CUCUMBERS: For cucurbits, especially cucumbers or bitter melons, but also for chayotes, melons, and even watermelons, a single wall of trellis netting will be used. You can choose between HORTOMALLAS® with 25x25cm squares (the most common) or 15x17cm squares, which are popular due to their ease of collection, cleaning, and multi-year reusability. Alternatively, the TRICOLOR® net is an economical option that can be reused for several consecutive cycles (as long as it’s left mounted on the posts).

The choice of the TRICOLOR® trellis net is common in open-field crops where the plan is to alternate and rotate vegetable varieties. Recovering the trellis net is not crucial in such cases, as the cost of collecting and reusing it exceeds the cost of using a new one. Additionally.

this choice is often made based on phytosanitary considerations, such as the presence of a virus or bacterial attack.

Support trellis
Cucumbers, being part of the cucurbit family, greatly benefit from the support of HORTOMALLAS® cucumber trellis netting.

For cucumbers, the ideal netting size is 1.5 or 2m. Remember that the cucumber trellis netting is installed about 20 to 30 cm above the plant, creating a higher trellis structure than the netting itself. This consideration is crucial when selecting the posts or stakes as well. Choosing the size of the posts that will serve as the heads of each row is equally important. Depending on factors like terrain, prevailing winds, and crop weight, a post system with varying spacing might be needed to support the selected netting.

Guide to LEGUMES Support trellis

Common legumes consumed as fresh vegetables include green beans, snap beans, yardlong beans, peas, and others. These usually require a single support wall, which can be provided by netting like HORTOMALLAS® or TRICOLOR®. The option of using a double vertical netting wall is considered for higher-value crops, such as oriental varieties like snow peas or snap peas.

In most cases, the plant’s tendrils offer sufficient attachment to the netting. The double wall is used where the variety is more susceptible to mechanical disease transmission or where manual support might lead to significant drops in production due to stress. The heights commonly used are 1.5 or 2m.

Cut Flowers Cultivation: Support trellis

Cultivating cut flowers is where HORTOFLOR® truly stands out in all its features, offering more room to choose higher-quality or more expensive inputs, such as SCROG. Thanks to its round and soft threads, the SCROG netting doesn’t damage the stems that might come into contact with it. In cut flower cultivation, the netting is installed in multiple layers horizontally, providing support at different levels and stems.

This system is particularly crucial for flowers like carnations, gladiolus, snapdragons, chrysanthemums, and roses. The first layer is installed during transplanting of the plant or cutting, and subsequent layers are added as the crop gains strength and growth velocity. The SCROG netting is more expensive than its extruded counterpart, but for high-value crops where flawless flowers are required, it is often preferred.

HORTOFLOR®:

In the case of HORTOFLOR® extruded netting, there are many farmers who attempt to use only one layer or level of netting and raise it as the plant grows. However, this method is NOT recommended because it damages the stems and can even create entry points for bacteria, viruses, or fungi where the plant is cut or mistreated. The idea of using HORTOFLOR® trellis netting is to have a passive support system where the plant grows through the squares, eliminating the need to adapt the netting to each growth phase.

HEMP:

The cultivation of some hemp species is regulated by local authorities. We advise consulting with your local competent authorities before starting this production, as the laws and permitted varieties vary from country to country and even from state to state in federations.

Medicinal hemp requires horizontal support, similar to cut flowers, as the commercially valuable part is the flower, which is later processed for infusions or dried for other prescribed medical uses.

Implementation of MALLAJUANA® using the SCROG trellising method

In English-speaking countries, this cultivation method is referred to as Sea of Green (SOG) or Screen of Green (SCROG) because the basic idea is to create a mass of vegetation that grows at the same pace and can make the most of both nutrients and lighting (which is often artificial) without one dominant plant outgrowing others and shading those around it. In these cultivations, the trellis nets used are the 2m MALLAJUANA® with 15x17cm openings. Some also use different sizes of MALLAJUANA® because many greenhouses are adapted from previous flower crops, and the beds already exist.

HORTOMALLAS® appreciates its customers for choosing us and driving us to become leaders in vegetable support systems. We hope that this brief guide has helped you determine which trellis net is most suitable for your needs.
