Grape / Munthiri (Green, Layer) Fruit Plant

Grapes (Vitis vinifera) are delicious fruits that grow on deciduous woody vines belonging to the flowering plant genus Vitis. Botanically, grapes are berries and are among the most popular fruits cultivated worldwide for fresh consumption, juice, raisins, and wine production.

Grapes grow in clusters of 15–300 fruits and can be crimson, black, dark blue, yellow, green, orange, or pink in colour. "White" grapes are actually green and are evolutionarily derived from purple grapes. Mutations in two regulatory genes prevent the production of anthocyanins, the natural pigments responsible for the purple colour. Anthocyanins and other polyphenols also contribute to the rich colour and antioxidant properties of red wines.

Grapes are typically oval to ellipsoid in shape. Plant grapevines in full sunlight to provide the warmth required for healthy growth and proper fruit ripening.

MAINTENANCE OF THE PLANTATION

Mulching is generally not recommended for grapevines, as it keeps the soil temperature too cool. Grapevines grow best in warm, well-drained soil.

After planting, water the vines regularly throughout the first year to establish a strong root system and encourage healthy shoot growth. Grapevines require sturdy support, such as an arbor, pergola, trellis, fence, or strong post, as they grow rapidly and become quite heavy. They can be trained and pruned into almost any desired shape depending on the available space.

FERTILIZING

During the first 2–3 years, apply compost around the base of the vines each spring. Grapevines grow vigorously and may benefit from additional nutrients during the growing season.

As the vines mature, fertilizer requirements depend on their overall health and vigour. Healthy, well-growing vines may require little or no additional fertilizer. Avoid mulching around the base of grapevines, as grape roots prefer warm soil conditions.

WEED CONTROL

Keep grass and weeds away from the base of grapevines to allow the soil to warm quickly during spring. Warmer soil encourages earlier growth and better vine development.

Remove weeds regularly by gentle hoeing or hand weeding throughout the growing season to reduce competition for water and nutrients.

PRUNING

Pruning depends on your preferred training system and the available garden space. Grapevines can be trained along fences, trellises, pergolas, arbors, or single support stakes.

During the first year, focus on developing a strong root system and a straight main trunk. Once the trunk reaches the desired height and lateral branches are established, prune the vine each spring before new growth begins. Proper pruning improves air circulation, reduces disease problems, and encourages healthy fruit production.

There are many different pruning and training methods, allowing grapevines to be shaped according to your landscape and growing requirements.

HARVEST YOUR GRAPES

The best way to determine if grapes are ripe is to taste a few fruits, as many varieties develop their colour before reaching full sweetness.

• Harvest full grape clusters using clean pruning shears or heavy scissors.

• Handle clusters carefully to avoid bruising the fruits.

• Remove any damaged, discoloured, or poor-quality berries.

• Cool the harvested grapes as soon as possible to maintain freshness and quality.
