After planting and early maintenance, the grapevine gradually enters a more productive growth phase. To ensure a generous harvest year after year, a few simple steps can help support its growth while minimizing disease.
Natural treatments to protect grapevines
Grapevines can be susceptible to certain diseases, particularly during wet springs or stormy periods. Fortunately, several natural solutions exist to strengthen the plants without resorting to harsh treatments.
Horsetail liquid fertilizer
Widely used in gardening, horsetail liquid fertilizer helps strengthen the grapevine’s natural defenses thanks to its high silica content. It is particularly effective in preventing moisture-related diseases. It can be sprayed in the spring and after rainy periods.
Nettle liquid fertilizer
Nettle liquid fertilizer stimulates growth and promotes a more vigorous vine. It also provides nutrients that are beneficial for the start of the growing season.
Natural sulfur
Sulfur remains a classic solution against powdery mildew. Used in moderation, it can be applied preventatively when the weather becomes hot and dry.
Bordeaux mixture
Made from copper, Bordeaux mixture helps limit the spread of downy mildew. In a home garden, a few preventive applications are usually sufficient.
Promoting biodiversity in the garden
A grapevine grown in a living environment is often more resistant to natural imbalances. Planting honey-producing flowers, attracting beneficial insects, or maintaining plant diversity around the vines helps maintain a healthy biological balance.
When do the vines really start producing?
Vines require a bit of patience before yielding a bountiful harvest. The first clusters
After planting:
- The first year is mainly for root establishment;
- A few bunches may appear as early as the second year;
- Production becomes more consistent starting in the third year.
Full production:
Generally, a vine reaches full production between the fourth and fifth years. At this stage, the root system is well developed, and the bunches improve in both quality and quantity. With proper care, a vine can then produce for several decades.
Monitoring grape ripening
As harvest time approaches, certain practices can help improve the quality of the grapes:
- Prune back excess foliage around the grapes
- Watch for signs of disease
- Avoid overwatering
- Protect the grapes from birds if necessary
Sunlight plays an essential role in sugar concentration and the development of aromas.
When to harvest the grapes?
Depending on the variety and region, the harvest generally takes place between August and October. There are a few signs that indicate the right level of ripeness:
- The berries become soft
- The color is fully developed
- The grapes are sweeter
- The seeds gradually turn brown
The best way is often to taste the clusters directly on the vine. With some regular care and appropriate natural treatments, it can become a sustainable and productive crop for many years.
