Growing Grapes in the Philippines

Can you grow grapes in the Philippines? This is one of the many questions people are asking whether growing grapes in the Philippines is possible or not.

In the Philippines and other tropical countries, grape plants need a trellis. In order for the vine to bear more fruit, the stalks (talbos) must be squeezed.

Unlike temperate countries where ninety percent (90 %) of the fruit of primary bud germinates, the trellis is no longer needed but pegs or poles and wire parallel to the tree (fence type trellis) are used.

How to grow or propagate fruiting grape branches?

  • Move the vine on the stake to the trellis. Each week the grape shoots grow one foot (1 foot.) Long.
  • Tie the straw tightly to the stake and loosen the rope on the grape stalk so that it does not get choked.
  • When the vine reaches the trunk, pinch the stalk to make many branches.
  • Continue to pinch the end every span or foot to re-branch two (2) or three (3) vines. Always pinch the end of the long stem to increase the fruit-bearing vine until the vine grows and has a pencil size branch that bears fruit.

Grape Fertilization

The grapes grew and grew fast, especially the roots of the green seeds that we call miracle grapes. It can be fruitful in just four (4) months. Before planting, apply triple 14 by ten tablespoons (10 tbsp.) Of sedimentary (basal) fertilizer to the bottom of the hole whose size is 1 1/2 x 1 1/2 x 1 1/2. Cover the compost with 1 foot of soil mixed with organic and chaff with viscous soil.

  • Before planting the grapes, put a stake on the surface so that the grapes can crawl up.
  • One week after planting, start applying fertilizer to be repeated every month.
  • Mix one part (1) of ammonium sulfate (21-0-0) and two (2) parts of Triple 14 of microelements.
  • With the rod make a hole four (4) inches deep which is a span from the tree.
  • In every four (4) holes with a span away from the tree put a tablespoon of manure or manure mixture and cover with soil.
  • Repeat the application of fertilizer after one month. As it grows gradually add fertilizer. Place the hole in the fertilizer container away from the tree and change the hole in the fertilizer container.
  • Put a tablespoon of the fertilizer mixture in the hole. Six (6) holes can be made one span away from the tree after 3 months that the grapes are in the trellis.
  • If fruiting and a lot of ga-pencil vines put pure triple 14 with micro-elements a month before fruiting.

Irrigation and Weeding

  • Water the grapes every second day to make them grow faster. Do not water the tree. Enough when the soil is wet.
  • Keep the bottom of the vineyard free of weeds so as not to deprive the nutrients of the fertilizer applied to the grapes.

Pests and Diseases of Grapes

The worm that is one of the grape pests rarely attacks. The beetle and moth attack if the leaves are dusty in the months of April, May, and June.

You can wash the dust on the leaf part with a hose to prevent it from being infested by mites. If the leaf is attacked by a moth and seems to have rust on the leaves, the drug Miticide can be sprayed.

Diseases are the problem in the rainy season while in the summer there are fewer disease issues in the grapes. Mold (mildew) and smallpox (anthracnose) are common diseases of grapes during the rainy season.

To prevent this disease, transparent plastic is placed on the surface of the vineyard (greenhouse) to prevent rain. Plastic from the compost sack can also be used.

Make a bamboo frame to hold the plastic. The distance between the vine trellis is one (1) meter to two (2) meters so that the leaves do not burn in the heat of the sun.

If there is no plastic roof (greenhouse), you can spray systemic fungicide to treat mold and smallpox. Spray weekly during the rainy season.

Grape Fruiting

Of all the plants, the grape is the most obedient plant that can be produced at any time according to the grower’s wishes and when he wants to harvest grapes. From the pruning of the vine, ninety (90) days will be counted before the red cardinal grapes ripen.

Green grapes and black (black ribier grapes) will count 115 days from pruning before the fruit ripens. So if you want to harvest grapes on your birthday, just count 90 days for red cardinal grapes and 115 days for green and black grapes variety.

And before the day of harvest comes pruning. Sixteen (16) week-old green grapes can be fertile if they are cared for normally.

If modified pruning is used no more leaves will be removed or removed. Just prune the elongated vine and remove the stalk at the end of the vine pruning.

In general pruning before fertilizing, first, apply triple 14 with microelements. Make 10 holes around the tree and place 20 spoons in each hole around the tree one to two feet away from the tree.

Do this one (1) month before pruning. Cut the parent vine to the size of a pencil so that all that remains is the fruit bud.

Prune the twigs until only two (2) buds are left, this is for the vine to grow and bear fruit after a few months.

In general pruning, all the leaves are removed and the tree is always watered so that the eyes or buds that bear fruit can continue.

Spray growth hormone (auxin) to increase flowering.

Usually, in the Philippines, grapes bloom only at the end of the pruned vine. So to increase the number of flower buds, spray growth hormone. If the flower buds have sprouted, apply fertilizer 17-0-17.

Depending on the number of flowers to be placed. If there are 10 healthy flowers, place 20 tablespoons of 17-0-17 in fifteen (15) holes of the spike with a distance of 1 ½ ft from the tree.

When the flower is in full bloom and wants to be seedless or seedless, spray or soak the flower in 50 ppm gibberellin. Do it only once.

The seeds of green, red, and black grapes will be lost but the fruit or berries will shrink to the size of imported flame-red seedless grapes. The green variety is what makes raisins like Thompson seedless very sweet.

If you want the imported varieties to be even sweeter, add 17-0-17 and 0-0-60 two months before the grapes ripen. For every 10 kilograms of fruit, place 1 kilogram of 17-0-17 and 0-0-60. Popular grape varieties farmed in the Philippines are red cardinal, catawba, Brazilian medium, and others.
