Training and Pruning For Grape Vine in pot
For the first 3 months Fertilize with ½ tsp urea and ½ tsp npk 16:16:16 every week and let it grow.
Install and arbor to support the branches, it can be 150 cm high arbor with 60 cm - 45 cm – 45 cm distance.
Let only one largest and strongest branch to grow, prune all other smaller and weaker branches.
Let it grow reach out the upper plank to get the strongest trunk.
Prune 1 node above the first lower wire or wooden plank.
For the second 3 months Fertilize with 1 tbs urea and 1 tbs npk 16:16:16 weekly.
Let 2 branches grow from the upper 1 or 2 nodes. Let them grow about meters before we prune it back into the first nodes.
Prune the two branches, leave 4 to 6 nodes on each branch. This is the primary branches or the cordon.
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.
On the 7 th month Fertilize with 1 tbs npk 16:16:16 + 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.
After the 8 th 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 16:16:16, water it and then stop watering it. Don’t 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.
In the fruiting From day 0 to day 14, you can spray foliar fertilizer for flowering, such as 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 3 rd – 5 th 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 won’t produce flower again. The flowers will start to bloom on the 22 nd – 26 th days. 14 days after all flowers bloomed, you can apply weekly 1 tsb of npk 16:16:16 + foliar fertilizer such as 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.
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 7 th month, we can not increase the fertilizer too much because it is a potted plant. For the second fruiting, use again the after 8 th 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 nodes. Prune the weakest branch. Prune the tertiary branch that haven’t produce grape back to its secondary branches. Have Fun…!
