Planting instructions

Perhaps the most important growth requirement for a triumph muscadine grapevine is ample sunlight. Without at least six hours of direct sunlight per day, this plant will likely fail to produce healthy fruits. This plant also prefers soils that are moist but well-draining. For this plant, you’ll need a hole that is as deep as the root ball is tall and about twice as wide. In most cases, you’ll want to grow your triumph muscadine grapevine where it can wrap itself around a support structure such as a trellis.

Watering and nutrients

During the first few years of this plant’s life, you will need to water it regularly to keep the soil moist and allow the roots to establish themselves. During the seasons to follow, your triumph muscadine grapevine should have good drought-tolerance. At most, you’ll need to give a mature plant about 1 inch of water or less per week. Your triumph muscadine grapevine will also benefit from two fertilizations per year. The first should occur during the spring, and the second should take place in early summer. For both feedings, you can use an all-purpose fertilizer.

Pollination

Pollination is critical if you wish to use your triumph muscadine grapevine to produce fruit. Interestingly, this plant can come in one of two forms. The first is a male plant that is capable of self-fertilization. The alternative is a female triumph muscadine grapevine, which requires cross-pollination to produce fruits. While this need for cross-pollination in the female version of the plant is a slight inconvenience, these female plants tend to give much higher fruit yields than their male counterparts.

Pruning

Pruning grapevines can be a complex task, but there are a few tips to keep in mind to guide you. Most pruning for this plant should occur during late winter. During the first few years of this plant’s life, you should prune it to encourage a single, strong trunk. After establishing the main trunk, you should establish a few primary lateral branches. These branches will be responsible for bearing this plant’s fruits. You should also use pruning as a way to train this plant to a support structure.

Pests, diseases, and animals

Those who have experience growing grapes know that pests and diseases can be harmful enough to stunt your grapevine’s growth and inhibit its ability to produce fruits. At times, these diseases can even kill your grapevine. The good news is that the triumph muscadine grapevine has an excellent ability to resist pests and diseases, including Pierce’s disease and phylloxera, two complications that are particularly harmful to most types of grapevines. This resilience makes for a productive grapevine that is comparatively easy to maintain.

Harvesting

After choosing a suitable growing location and giving your triumph muscadine grapevine the right care, it should reward you with as many grapes as you could ever want. These grapes typically ripen during mid to late summer and are often ready for harvest between the months of August and September. Typically, it is best to test one or two grapes for sweetness before you harvest the rest. If you find that the flavor is favorable, the chances are that most grapes that look similar will be ready to pick as well.

Achieving maximum results

The triumph muscadine grapevine has several advantages over other types of grapevines. One such advantage is this plant’s ability to withstand relatively cold temperatures. Unlike other grape varieties, the triumph muscadine grapevine is able to survive in regions as far north as hardiness zone 7. Despite that, you should be wary of pruning this plant just before a frost arrives, as the fresh pruning wounds will be incredibly vulnerable to freezing temperatures. For that reason, you should always prune in late winter or early spring when the threat of frost has passed.
