Starting Pruning Wisconsin Grape Growers Association Tuesday January 5, 2010 Timothy K. Rehbein University of Wisconsin Extension Agricultural Agent – Vernon County

Slide 3

Why Prune? "Pruning and preparing are maybe the most imperative social administration hones for grapes. An intensive comprehension of the ideas of pruning seriousness and harvest load is basic to supported creation of brilliant natural product." Midwest Grape Production Guide from Ohio State University Extension pubs@ag.osu.edu http://ohioline.osu.edu/b919/

Slide 4

Pruning and Training - Definitions Pruning = Cutting amid lethargy Best time is late winter, early spring Training = Cutting amid the developing season Canes are 10 to 20 hubs in length Spurs are 2 to 6 hubs in length Fruiting goad is 2 to 6 hubs in length Renewal goad is 1 to 2 hubs in length

Slide 5

Pruning and Training - Definitions Green shoot is ebb and flow years development Cane is a green shoot in its second year Trunk or cordon is a shoot in its third year or more established Trunk is changeless vertical development Cordon is lasting even development Pinch the tip is expelling the end segment of an on a level plane developing shoot

Slide 6

Pruning and Training - Definitions Heading the shoot is cutting or evacuating the end segment of a vertically developing shoot Apical Dominance implies the live bud most distant on the shoot or stick is "Lead Dog" Bud is an undeveloped shoot in the leaf hub (at the hub) – Primary(1) Secondary(2) Tertiary(3) Fruiting Cane/Wood is a stick that has no less than one grape group on it

Pruning and Training

Slide 10

Pruning and Training Pruning in the initial couple of years in the wake of planting helps the vine build up a decent root framework A solid relationship has been appeared between aggregate leaf region AND root dry weight Suggests more than one shoot in first year

Slide 11

Pruning and Training Pruning the develop vine "is to adjust" the yield load to the vine's capacity to deliver A develop grape vine can have a few hundred buds before pruning, with half having the capacity to deliver organic product Grape vines create natural product just from ONE YEAR OLD WOOD Pruning modifies the size and state of the vine

Slide 12

Trellis Fundamentals 3 Main sorts of trellis frameworks that are utilized are: High Wire Cordon Geneva Double Curtain Vertical Shoot Positioning

Slide 13

Trellis Types High Cordon 5-6 ft. high Trailing development Moderate energy development Moderate fruitful soils Geneva Double Curtain 5-6 ft. high 3-4 ft. cross piece High life Fertile soils

Slide 14

Trellis Types Vertical Shoot Positioning Fruiting wire 2-4 ft. high Upright development Need find wires Labor escalated "situating" Need to trim top Smart Dyson Scott Henry 4 Arm Kniffen

Slide 15

Planting Pruning If planting exposed root stock, chop down to 2 to 8 buds on one stem No pruning required if planting nursery plants In the spring of the second season, you may have the capacity to abandon some trunk…

Slide 16

Beginning of Second Year Should have the capacity to spare a portion of the primary year's development to make the storage compartment Cane ought to be in any event ¼ creep in measurement (pencil size) to continue VSP, ought to effectively make the fruiting wire and some cordon – may need to "head" the vine On High Cordon, may make the fruiting wire in the principal year Some producers "institutionalize" their plants by pruning all at the vines to a similar tallness

Slide 17

3 rd Pruning On the high cordon, you need to develop more trunk than the VSP During the developing season, tip or head the sticks that are completing out the "cordon" On the VSP you ought to have the capacity to develop sticks. "Hang some organic product?"

Slide 18

Cordon Training As the green shoot develops that will in the long run turn into the cordon, you can first attach the shoot to the bolster wire When this green shoot turns into the stick in the following year, cultivators typically wind the stick around the bolster wire and secure the very end of the stick to the bolster wire with tree-bolt or twine or plastic tie

Slide 19

Mature Plant Pruning In the 3 rd season we can begin to "hang natural product" for a little harvest In the 4 th season we start generation

Slide 20

Pruning Rules of Thumb Keep the plant to a characterized space on the trellis Maximum sun presentation Ripen the perfect measure of yield Ripen wood and buds for the following year's harvest

Slide 21

Pruning Rules of Thumb Bud means most assortments = 40 buds for each vine for medium estimated bunches and 60 buds for every vine for little groups (Foch) Example: 545 plants for each section of land with 40 buds, 2 groups for every bud, medium group at 6 oz. per group turns out to 6 X 2 = 12 oz isolated by 16 oz/lbs = .75 pounds of natural product per bud X 40 buds = 30 pounds for every plant X 545 plants = 16,350 pounds or a little more than 8 tons for each section of land

Slide 22

Pruning Rules of Thumb Check for winter kill on buds before pruning on the off chance that you have to leave more buds Double pruning can postpone budbreak Your last pruning will be later into the spring and you will get more vine "dying" which does not hurt the vine Check for auxiliary bud development regardless of the possibility that the essential is developing Cluster thin if necessary

Slide 23

Pruning Rules of Thumb Always keep solid, infection free wood Keep sticks as near the cordon as could be allowed Cane bark ought to be a splendid rosy – cocoa shading (with some assortment exemptions)

Slide 24

Balanced Pruning Helps You REACH Your Vines Best Potential-You will develop with your vines.

Slide 33

What I gained from Growers 2009

Slide 34

20 – 30% south slant truly had an effect Phosphorus Acid has no control on Black Rot in Frontenac Late collect – nearly ice wine – grapes are to a great degree work escalated Dropped edit toward the beginning of August helped Frontenac achieve 25% brix
