Late spring frost

One cold night after the trees flower can kill a year's fruit, and in Georgia spring frost is not insured.

Who and when

Stone fruit, vines and hazelnuts in Shida Kartli, Kakheti and Samegrelo. March to April. In 2025 frost hit cherries in Shida Kartli.

Getting worse or not: not clear. Our reading (not proven): milder winters bring buds out earlier, so a normal frost does more harm.

Right now

Right now (autumn 2026)

  • A strong El Niño is building, and models point to a milder winter for most of Europe (no Caucasus forecast found). A mild winter can bring buds out early. A watch point, not a forecast.
  • Spring frost is not covered by state agro-insurance (only autumn frost on citrus).
Before

Before: get ready

Crops and trees

  1. Find your frost pockets: low spots where cold air sits. Cut gaps in hedges on the low side so cold air drains away. Don't plant new orchards there. When: now.
  2. For cold spots, plant later-flowering varieties (they may give less fruit; ask locally which suit you). When: Oct–Nov or March.
  3. Pruning vines in frost-prone places: keep the fruiting wood higher. Raising it 0.3–0.5 m can gain 1–2 °C. When: winter pruning.
  4. Keep soil under trees and vines bare, firm and moist: clear tall grass. Bare soil is 1–3 °C warmer. When: February to May.
  5. Check the forecast every evening in March and April. The METEO.GOV.GE app lists no frost warning, so rely on the forecast.
  6. On a frost night: cover seedlings and small trees (thin plastic gains about 1 °C, thick about 5 °C). If you have water, wet the soil 1–2 days before, or flood the furrows the night before (about 1–4 °C).
  7. Sprinklers and wind machines work but cost a lot; one wind machine covers 4–5 ha, so share with neighbours. Done wrongly, frost protection can be worse than nothing (general practice, check locally).

Animals

  1. Before the first hard freeze, check water pipes and troughs. When: now (October).

Money: spring frost is not insured; replanting an orchard can be part of a State Agro Co-financing project (up to 50%, 55% for cooperatives and highland or dividing-line villages).

During

During: when it hits

  1. Before dark, check the forecast and warnings.
  2. Animals: make sure water is not frozen.
  3. Water the soil or flood the furrows, and cover small plants, before the frost comes.
  4. If you use sprinklers, keep them running at the right rate all night (2–5 mm an hour). Too little water does more harm than none.
  5. Don't rely on smoke: it is weak and not recommended.
After

After: recover

First days

  • Take photos with date, time and place.
  • Don't judge too soon. Flowers can look fine and be dead inside; brown petals alone don't mean loss.

First weeks

  • After about a week, cut open blossoms from high and low spots. A brown or black centre means that flower is dead (general practice, check locally).
  • Total crop loss: give no more nitrogen fertiliser that season. Good fruit set: fertilise as normal (general practice, check locally).
  • Thinning: over 75% damage, don't thin. Under about 20%, thin as normal. In between, thin lightly (general practice, check locally).
  • Keep protecting leaves against disease: they feed next year's buds.

Money and help

  • Spring frost is not insured, and no state frost aid was found.
  • Keep your own dated photos: they may be the only record.
Build back better

Build back better

  1. Replant cold spots with later-flowering varieties, or move orchards off frost pockets.
  2. Keep fruiting wood higher in frost-prone vineyards.
  3. Plan water for frost nights, so you can wet the soil.
  4. Share sprinklers or wind machines through a group of farms.

What the farm check looks for

Orchards or vineyards in Shida Kartli, Kakheti or Samegrelo; early-flowering fruit (apricot, cherry); low-lying plots; tall grass under trees; no water for frost nights.
