Types of Grapes
The first step is to choose the right grape variety for your climate and soil type. There are three main types of grapes: American, European, and hybrid.
American vigorous grapes (Vitis labrusca) are the most cold-hardy and can grow in colder climates. They include varieties like Concord and Niagara.
European grapes (Vitis vinifera) require a long, warm growing season and do not do well in cold climates. They include varieties like Cabernet Sauvignon and Chardonnay.
Hybrid grapes are a mix of American and European varieties and are more tolerant to cold temperatures than European grapes. They include varieties like Chancellor and Cayuga White. So, how to grow grapes properly?
How to Grow Grapes? Choose the Right Soil Type
So, how to grow grapes and what type of soil is the best? Grapes need well-drained soil that is high in organic matter. The best way to prepare your soil is to test it before you plant. You can get your soil tested at a local cooperative extension office.
If your soil is heavy clay, you will need to amend it with sand or compost to improve drainage. If your soil is too sandy, you will need to add organic matter to help it retain moisture.
Loam soil, which is a mix of sand, silt, and clay, is the best type of soil for grapes.
Temperature
Grapes need a long, warm growing season to ripen properly. In most cases, they will need at least 100 days with temperatures above 70 degrees Fahrenheit. Any temperature below this causes vegetative growth, which means the grapes will not ripen.
Site Selection
If you want to learn how to grow grapes, the site is very important. Grapes need full sun to grow well. The grape vines should also be protected from strong winds, which can damage the vines.
When choosing a site for your grapevines, make sure to choose an area that gets at least 8 hours of sunlight per day. You should also avoid areas that are prone to flooding or excessive moisture.
Planting
So, how to grow grapes, and when should they be planted? Grapevines are typically planted in the fall or spring (between October and March).
When planting, make sure to dig a hole that is twice as wide as the root ball and just deep enough to cover the roots. Gently backfill the hole with soil and water well.
After planting, prune the grapevine down to two buds. This will help it to grow strong roots and produce more fruit.
Watering
Grapevines need to be watered regularly, especially when they are first planted. They should be watered deeply and allowed to dry out between watering. 8 to 10 gallons of water per day is a good rule of thumb for a fully trellised mature vine.
Fertilizing
So, how to grow grapes and ensure they get all the nutrients? Grapevines should be fertilized, but the amount depends on the tissue analysis. Manure or compost can be used as a natural fertilizer. Nitrogen-rich fertilizers are also a good option. Do not fertilize in the first year.
Pruning the Grapevine
Grapevines need to be pruned every year to produce the best fruit. Winter is the best time to prune grapevines. During this time, the vine is dormant and can be pruned without harming the plant.
To prune a grapevine, start by removing any dead or diseased wood. Next, remove any weak or unproductive growth. Pruning is very important, as it promotes new growth.
When Should You Harvest Grapes?
Grapes are typically harvested 30-70 days after the fruit set, but that depends on the variety. The grapes should be ripe and have a deep color. To test for ripeness, gently squeeze the grape. If it pops easily, it is ready to be harvested.
Depending on the zone, the harvesting time can be from late August to early October.
After harvesting, the grapes can be made into wine, juice, or jam. They can also be eaten fresh.
So, How to Grow Grapes?
Now that you know how to grow grapes, it’s time to get started! Choose a grape variety that is suited to your climate and soil type. To grow vines of the same variety in adjacent vines (or doubles) with 6 to 10 feet between vines. Planting holes should be dug 12 inches deep and 12 inches wide for each plant; fill them with 4 inches of soil. Trim damaged roots and set the plant into the hole about 3/4 inch deeper than it grew in the nursery.
Add soil to the planting hole and tamp gently. Water the plant deeply immediately after planting and again every week during the first growing season. Mound 2 to 4 inches of soil around the base of each plant in early spring. As the vines grow, train them onto a trellis or arbor to support their growth.
