Grapevines are one of the most rewarding plants you can grow on a Greek property — a terrace, a pergola over a holiday-rental courtyard, or a hotel garden — but without pruning they quickly turn into a woody tangle that produces little fruit. The video above walks through the full pruning process visually; this guide breaks it down into clear, ordered steps you can follow even if you have never picked up a pair of secateurs before. Done correctly, winter pruning takes under an hour per vine and pays off for an entire season.
Why Pruning Matters for Greek Grapevines
In the Mediterranean climate, grapevines grow vigorously. Without annual pruning, energy gets diverted into excess shoots and old wood rather than the clusters of grapes you actually want. Hard pruning in late winter — after the coldest nights have passed but before the buds swell — resets the vine's energy so it channels everything into a controlled number of productive canes.
For rental properties and hotels, there is a practical reason beyond harvest: an unpruned vine on a pergola becomes a fire hazard in the dry Greek summer and can lift roof tiles with its weight. A pruned vine stays manageable, looks welcoming to guests, and provides shade without structural damage.
Spur Pruning vs Cane Pruning: Which One to Use
Most table-grape and ornamental vines on Greek properties are trained using spur pruning, where you cut each arm (cordon) back to short two-bud spurs spaced 15–20 cm apart along a horizontal wire or beam. This is the easiest method for beginners and works well on pergola-style trellises common in Greece.
Cane pruning — leaving one or two long canes of 8–12 buds — is preferred for wine-grape varieties and produces higher fruit quality, but it requires a more precise eye for selecting which cane to keep. When in doubt for a garden vine, spur pruning is the safer choice.
How to Prune a Grapevine: Step by Step
- 1
Wait for the right moment
Prune in late winter, typically February in most of Greece, after the risk of hard frost has passed but before any green bud movement begins. Cutting too early exposes fresh wounds to frost; cutting too late diverts sap that has already started rising and weakens the vine. In Crete or the southern islands you can prune as early as late January.

Gather the right tools
You need a pair of sharp bypass secateurs (not anvil-type, which crush wood), loppers for thicker cordons over 2 cm, and a pruning saw for any dead trunks. Wipe blades with isopropyl alcohol between vines to avoid spreading fungal disease. Blunt or dirty blades are the most common cause of disease entry in Greek home vineyards.

Remove all last year's spent wood
Start by cutting away every shoot that fruited last season — these will not fruit again. Work outward from the main trunk along each cordon arm. If you practise spur pruning, cut each spur back to two healthy outward-facing buds. If you practise cane pruning, remove the old cane entirely and select one vigorous new cane from near the head of the vine, tying it along the wire.
- 4
Thin to the right number of buds
A common beginner mistake is leaving too many buds. As a rule of thumb, leave roughly 30–50 buds total across the whole vine — fewer for a young vine (under 3 years old), more for a mature, established plant on a full-size pergola. Overcrowding leads to dense shade, poor air circulation, and powdery mildew, which is especially problematic in humid coastal areas.
- 5
Clean up and protect cut ends
Remove all pruned material from around the base of the vine — do not compost it if the vine has shown any signs of disease. For cuts on main cordons wider than 1 cm, apply a wound sealant paste (available at any Greek agro-store) to slow drying and block Eutypa spore entry. Water the vine well and apply a balanced potassium-rich fertiliser to support the season ahead.

FAQ
- Can I prune a grapevine in summer?
- Yes, but summer pruning is lighter maintenance, not the main structural cut. In summer you remove unwanted lateral shoots that shade the grape clusters, a practice called 'shoot thinning' or 'summer topping'. This improves fruit colour and ripening but does not replace the hard winter prune that shapes the vine.
- What happens if I skip pruning for one year?
- Missing one year will not kill the vine, but you will get far fewer grapes and a messier structure to correct the following winter. After two or more years without pruning, the vine develops excess old wood, greatly reduces fruit, and becomes very difficult to renovate without dramatic cutback over two or three seasons.
- How do I prune a very old, neglected grapevine?
- Renovate over two seasons rather than one brutal cutback. In year one, remove dead wood and the most tangled canes, reducing the load by about half. In year two, complete the shaping to your chosen training system. Trying to do everything at once shocks the vine and can kill it, especially on established ornamental vines on old Greek properties.
