(29 cards)
When talking about Site Selection, what three main considerations must be made?
Environmental conditions
Business considerations
Grape variety
At what age are most vines replaced?
30-50 years old
What are the two types of vine training?
Head training
Cordon training
In which two seasons will vine pruning happen?
Winter and Summer
The number of what is dictated by winter pruning?
Number of buds that will form shoots in the next growing season
What are the two styles of winter pruning?
Spur pruning
Replacement cane pruning
How many buds are typically left on a spur?
How many on a cane?
2-3 buds
8-20 buds
Replacement cane pruning will generally only be used on vines trained in which way?
Head trained
What is another name for replacement cane pruning?
Guyot
single Guyot or double Guyot if two canes retained
What does trimming leaves in summer pruning achieve?
Restricts vegetative growth which directs sugar production to the grapes
Increases sunlight exposure
Bush vines are generally … trained and … pruned?
Head-trained and spur-pruned

What are the three benefits of having a trellised vineyard?
Sunlight
Air circulation

Let the canopy hang down
What two factors will most likely be considered when planting, as far as density is concerned?
Availability of nutrients and water
What might happen if there are too few buds on the vine?
Each bud will have access to too much energy and grow vigorously
In fertile soils, what technique has been developed to limit the growth of vines where high-density planting is not enough?
Training vines with multiple cordons
What technique is used if yields look like they might be too high?
Green harvesting
Why is green harvesting risky?
If done at the wrong time the vine may compensate for lost grapes by increasing grape size (yield may return to original size and be dilute)
What are the five main pests in the vineyard?
Phylloxera Nematodes Birds Mammals Insects
What are the 6 steps of vineyard cycle?
- Budburst
- Early shoot and leaf growth
- Flowering and fruit set
