Training and Pruning

1
Training and Pruning

• For Grape Vine in pot

2
For the first 3 months

• Fertilize with ½ tsp urea and ½ tsp npk
  161616 every week and let it grow.

3

• Install and arbor to support the branches, it
  can be 150 cm high arbor with 60 cm - 45 cm 45
  cm distance.

4

• Let only one largest and strongest branch to
  grow, prune all other smaller and weaker branches.

5

• Let it grow reach out the upper plank to get the
  strongest trunk.

6

• Prune 1 node above the first lower wire or
  wooden plank.

7
For the second 3 months

• Fertilize with 1 tbs urea and 1 tbs npk 161616
  weekly.

8

• Let 2 branches grow from the upper 1 or 2 nodes.
  Let them grow about 1 - 2 meters before we prune
  it back into the first 4 - 6 nodes.

9

• Prune the two branches, leave 4 to 6 nodes on
  each branch. This is the primary branches or the
  cordon.

10

• Let the branches grow from the nodes. If some
  nodes grow faster, we can pinch the tip of the
  branch to slow down the growth and let the
  nutrition go to other branches.
• This is to balance the growth. This is called
  secondary branches.
• Let them grow to the upper arbor and prune it
  back to one node above second arbor so we can tie
  them on the second arbor.

11
On the 7th month

• Fertilize with 1 tbs npk 161616 ½ tbs Tsp
  ½ tbs Kcl weekly.
• Let the tertiary branches grow from the
  secondary branches until their bark turn from
  green into brown wooden bark.

12
After the 8th month

• After the tertiary branches bark changed from
  green into brown color, we can step into the
  fruiting phase.
• 15 days before pruning, fertilize with ½ kg of
  manure.
• 10 days before pruning, fertilize with 1 tbs Tsp
  1 tbs Kcl.
• 5 days before pruning, fertilize with 2 tbs Npk
  161616, water it and then stop watering it.
  Dont let any water or rain goes into the pot,
  let the pot dry out.
• 1 day before pruning, in the evening, water the
  pot again.
• On day 0, water it in the morning before
  pruning, prune it in the next 1-2 hour, prune all
  tertiary branches, leave 3-5 nodes in each
  secondary branch.

13
In the fruiting

• From day 0 to day 14, you can spray foliar
  fertilizer for flowering, such as 10-55-10 every
  7 days.
• The new tertiary branches will grow from the
  secondary branches.
• These new tertiary branches might have grape
  flower clusters grow from the adjacent of the 3rd
  5th leave. If there is no flower, you can keep
  the branch for the next fruiting branch.
• If the flower comes out but then die, you must
  prune the tertiary branch back to 1 or 2 nodes
  because it wont produce flower again.
• The flowers will start to bloom on the 22nd
  26th days.
• 14 days after all flowers bloomed, you can apply
  weekly 1 tsb of npk 161616 foliar fertilizer
  such as 6-30-30.
• Depends on the grape variety, you can stop
  fertilizing 30 days before harvest.
• 5 days before you pick the grapes, stop watering
  the pot, and water it again as usual after
  picking the grape.
• Mark the nodes where the grape produced with red
  plastic ribbon for the next fruiting pruning.

14
The next fruiting

• The branches that have no flower will grow along
  with the branches that have grape.
• After the harvest, apply 30 grams of dolomite to
  lower the soil acidity.
• Let the branches continue to grow until the bark
  change the color from green into brown.
• Fertilize weekly as on the 7th month, we can not
  increase the fertilizer too much because it is a
  potted plant.
• For the second fruiting, use again the after 8th
  month fertilizing and pruning rules.
• In the second fruiting, prune the branches that
  already produced grape that we marked with red
  ribbon.
• The tertiary branches that already produce
  branches become the new secondary branches, prune
  branches grow from this new secondary branches.
  Leave the new secondary branches with 3 - 5
  nodes.
• Prune the weakest branch.
• Prune the tertiary branch that havent produce
  grape back to its secondary branches.
• Have Fun!
