How to Grow Red Rose Grapes? Detailed Explanation of Planting Techniques and Precautions

Do you eat grapes often in your daily life? And every time we go to the fruit supermarket to buy grapes, there are many different types of grapes with different tastes. Some people like big grapes, some like sweet grapes, some like red grapes, and some like purple grapes. Red Rose grapes are a kind of small, sweet grape. If someone wants to grow one at home, how should Red Rose grapes be planted?

How to Grow Red Rose Grapes

Stem cuttings are commonly used for propagation. Cut vigorous one-year-old branches with plump buds. Cut them into single-bud or double-bud cuttings about 5-15cm long, and insert them in the seedbed in February at a spacing of 15cm×50cm.

Red Rose Grape Planting Techniques and Precautions

I. Planting Techniques

1. Site selection: choose a plot with high terrain, preferably a sunny slope, with fertile and deep sandy loam or loose soil, a pH of 6.3——7.3, and good irrigation and drainage. Since grape growing is a labor-intensive industry with a lot of manual work, it is best to build the vineyard in a place with sufficient labor.

2. Establishing supports: the supports can be concrete posts about 2.5m long and 300px square, buried along the row with a post spacing of about 6m and a burial depth of 60——1750px. The model of single-post double-arm open trellis followed by a pergola is conducive to early fruiting and high yield later.

3. Planting: choose 1——2-year-old grafted seedlings with complete root systems and more fibrous roots. The plant spacing can be 1.5m and the row spacing 6m. The density should be small to improve ventilation and light penetration and reduce disease factors. In the north, plant when the spring soil temperature reaches 7——10 degrees. In the south, where winters are warm, planting can be done in late autumn or winter.

II. Precautions

1. The various Red Rose grape populations have different temperature requirements at different growth stages.

2. Red Rose grapes are water-loving plants, so attention should be paid to watering.

3. Grapes are light-loving plants and have relatively high light requirements. The length of light duration has a great impact on grape growth and development, yield, and quality.

Fertilizer and Water Management for Red Rose Grapes

1. Apply base fertilizer: base fertilizer is mainly applied in furrows, once a year. On one side of the plant, about 40cm from the trunk, open a fertilizer furrow 30cm wide and 60cm deep. The next year, open a furrow on the other side to apply base fertilizer. Start fertilizing when 60%-70% of the leaves turn yellow and then become light yellow.

2. Topdressing: carry out topdressing according to the grape growth stage. The first application is before bud break, with a bud-promoting fertilizer mainly of nitrogen fertilizer, about 50g per plant. The second topdressing period is the fruit enlargement stage, with a fruit-promoting fertilizer mainly of phosphorus and potassium fertilizers, mainly 0.3% potassium dihydrogen phosphate, to promote fruit enlargement, flower bud differentiation, and fruit ripening.

3. Foliar fertilization: before flowering, combine foliar fertilization with disease-prevention spraying. Spray the leaves with a 0.2%-0.3% borax solution + 0.3% potassium dihydrogen phosphate.

4. Watering: during the growing season, watering should mainly be light, with a reduced flow rate and without flooding the ridges. After irrigation, open the upper and lower vents to dehumidify to prevent sunscald and disease outbreaks. When the soil surface turns white, level and rake the surface.

Cluster Management of Red Rose Grapes

1. Cluster thinning of Red Rose grapes: according to high-quality fruit standards, the yield per 667 sq m is best controlled at about 1500-2000kg, with each cluster kept at about 750g, that is, 1500-2000 clusters retained per 667 sq m. If 150 plants are planted per 667 sq m, then on average each main vine retains 5-7 clusters, and each plant has 10-15 clusters; excess clusters can be thinned out.

2. Remove secondary clusters and pinch the cluster tips of Red Rose grapes: straighten the clusters caught between branches so that they hang naturally. The cluster length should be 12-15cm, with the maximum not exceeding 20cm, so that the whole cluster is tight but not crowded, and loose but not scattered.

3. Berry thinning: remove small berries, deformed berries, damaged berries, and overly dense and crowded berries pressing against each other from the Red Rose grape clusters. To save labor, some small clusters on the rachis can also be removed. Keep about 50 berries per cluster, with an average berry weight of 14-15g, which can ensure about 750g per cluster.

4. Bagging: to ensure that Red Rose grape clusters are not polluted by pesticides and other contaminants, reduce damage from pests, diseases, and birds, prevent the clusters from rubbing against leaves and damaging the fruit surface, avoid sunscald and overly strong or deep coloration of the berries, and prevent fruit cracking and hail damage to the fruit surface, the clusters should be bagged in time after berry thinning. Before bagging, first spray the thinned clusters once with a 1:0.7:200 Bordeaux mixture. After the liquid on the fruit surface dries in the wind, put on the paper bag, tie the upper opening tightly and fix it to the old vine, and leave a ventilation opening at each of the two lower corners to allow air circulation. The paper bag is generally 33cm long and 30cm wide, and single-layer paper bags specially for grapes that have been soaked in fungicide should be selected.

Red Rose grapes are not only sweet and sour and tasty, but their flesh is also particularly firm, so if you pick or buy a lot, you do not need to worry that they will be hard to keep, because Red Rose grapes do not spoil easily, so they are very suitable for storage. The above introduced the planting methods of Red Rose grapes. I wonder if everyone has learned them.
