Peat drying depends entirely on weather: warm, windy, dry days are ideal, intermittent rain is tolerable once the blocks are footed, and a long wet spell while blocks are still spread flat ruins the season’s harvest. Time the cutting for the driest period, and cut in several batches so that one wet fortnight cannot take it all.
Part of Peat Harvesting
How weather affects peat drying at each stage, and how to schedule the cutting around it.
Evaporation Needs Heat, Wind And Dry Air
Drying is evaporation, and it goes faster with warmth, moving air and low humidity. The parent article gives three conditions: ideal is warm, windy, dry weather (summer in temperate regions); acceptable is intermittent rain if blocks are footed, because standing blocks shed water; the problem is extended wet weather in the spreading phase.
In wet climates the parent says cutting traditionally begins in April-May for an August harvest.
| Stage | Wet-weather risk | Response |
|---|---|---|
| Spread flat (weeks 1-2) | Highest: blocks reabsorb water | Cut only with a dry spell forecast |
| Footed (weeks 3-4) | Moderate: shed water | Re-stand slumped blocks |
| Clamped (weeks 5-8) | Lower with a good cap | Keep the cap sound |
Method: Schedule Around The Weather
Step 1: Read the forecast. Use cloud and pressure signs (Weather Forecasting) to choose the day to cut.
Step 2: Cut in batches. Spread the cutting over several weeks, so that each batch is at a different stage. One wet fortnight then hits only the batch in the spreading stage.
Step 3: Foot early when rain threatens. Move blocks that are firm enough to stand up.
Step 4: Protect the cap. Check sod and tarps after wind and rain.
Step 5: Keep a reserve. Store the fuel from one good year against a poor one.
Common Mistakes
- Cutting everything on one dry day. A wet turn then ruins all of it.
- Cutting too late in the year. Drying in autumn is slow.
- Ignoring the wind. A windy day dries better than a still, warm one.
Safety
Wet, exposed bog work chills people
Bogs are open, often windswept, and wet underfoot. Soaked clothes in wind lose heat fast, and cold judgement fails before the cold is noticed. Wear waterproofs and spare dry layers, and know the signs of hypothermia (Hypothermia Recognition and Rewarming).
