Pruning Grapevines is one of the most commonly
overlooked tasks of growing grapes and keeping a successful backyard
grape growing garden. Most farmers new to grape growing have not yet
understood how important it is to prune grapevines in order to achieve
high quality grapes from their vines. I have heard from plenty of grape
growing hobbyists, with huge massive crops, complain at how poor the
quality of wine grapes their grapevines have produced. They don't have
the faintest clue as to why their enormous grape crop fail to produce
top quality grapes.
The reason for these dissapointments lie with grape pruning.
You
see, pruning grapes is a MUST if you want to produce great tasting
fruit. When you don't prune grapevines, the vine itself will produce
more grapes than it can handle. Meaning that the grapevine does not
have enough energy to ripen all those fruits, hence the grape clusters
will be poor and worthless. The stems tend to grow crooked and are
generally not strong enough to withstand the winter.
Pruning
grapevines is also important to control the size of your grape crop.
Grapevines can typically grow to sized large enough to cover entire
acres of space. This does not mean that they produce the best quality
fruits. On the contrary, a pruned grapevine, that is, a grapevine that
has been pruned correctly will in the long run give you the best grapes
money can buy. Below I have listed some quick tips to help you get
started on your grapevine pruning.
Pruning Grapevines Tip #1:
Though I cannot stress enough the importance of grapevine pruning,
I must remind you to carefully determine when you will be pruning your
grapevines because it may affect the overall results of your cause.
Keep in mind that he best time of the year to prune grapes is in the
early spring or the late winter. This will ensure ultimate fruit growth
for next year's season.
Pruning Grapevines Tip #2:
Before you start pruning grapevines, you must estimate the amount
of 1 year old wood in pounds and then hold the applicable amount of
fruiting canes per vine. It would be most beneficial to train your
grapevines to the Four Cane Kniffin System which requires 4 fruiting
canes. Make sure you leave an equivalent amount of renewal spurs
because the buds on these spurs will be your main grape cane growers
next season.
Pruning Grapevines Tip #3:
Once you have pruned your grapevines down, completely cut down all
the other canes and using their weight, determine the number of buds to
leave on your vine. It is recommended to use the formula of 'balanced
pruning' also known as the '30 plus 10' formula which means leaving 30
buds for the first pound of removed canes followed by an additional 10
buds per extra pound.
Remember the ultimate goal of grapevine
pruning is to manage your grapevine crop size, modify the quality of
the fruits, and regulate the growth to a point where you can manage it.
Pruning grapevines can be challenging at first, but the rewards of
proper grapevine pruning are well worth the efforts. Don't fall victim
to a massive crop of unpruned grapevines and poor quality fruit. It
defeats the whole purpose of growing grapevines.
