Crown Exhaustion: Forcing is a massive energy drain. Only use established (3yr+) crowns. After harvest, remove the jar and mulch with 4 inches of well-rotted manure. Do not harvest from this crown again for 12-18 months.
Harvest Technique: Never cut with a knife. Grasp at the base and pull with a sharp twist. A clean detachment prevents the remaining stump from rotting into the crown heart.
Stool Renewal: Remove the three oldest, mossy limbs at the base every February. This maintains a cycle of young, productive "whips."
Wind Pollination: Pruning must wait until catkins turn yellow and release pollen. Look for the "tiny red spiders"—the female flowers—on 2nd-year wood. Prune around these carefully.
Structure: Harvested hazel stems are "pea sticks." Their rough bark provides superior grip for climbing legumes compared to bamboo.
Seedling Thermals: Germinate at 21°C, but drop immediately to 15-16°C after sprouting. High heat with low Feb/Mar light creates "leggy" stems. Cold-shocking slightly creates thick, sturdy cellular walls.
May 24 Safe-Date: In Norfolk, planting out before late May is a gamble. Tomatoes stall if nights hit <10°C. Use the Skeleton House as a 10-day "hardening off" buffer.
Axillary Management: Pinch out side-shoots daily. In high-humidity glass, large wounds invite Botrytis; small, fingernail-pinched wounds heal in hours.
Vascular Bleeding: Grapes have high hydraulic sap pressure. Pruning in March, as sap rises, causes "weeping." This loss of sugars weakens early growth and invites pathogens. Prune strictly during deepest winter dormancy.
Geometry: Use the Spur system. Prune side-growth to two buds. The first is your replacement wood; the second is your fruit producer. Airflow is your primary defense against Powdery Mildew.
Chemistry: Apply high-potash mulch now. This toughens the fruit skins, preventing splitting during August rains.
Root Restriction: Unrestricted figs produce wood, not fruit. "Slabbing" (placing paving slabs 18 inches deep in a square) induces the stress needed for reproductive cycles.
Embryo Protection: UK figs come from the pea-sized embryos formed on last year's tips. If these turn black (frost damage), you lose the crop. Protect with fleece if temps hit < -2°C.
Summer Pinching: In June, pinch out the terminal buds. This forces the sap back into the developing fruit rather than new leaf growth.
Chitting Science: Light triggers the development of "chits." Aim for short, purple-green nubs. Long white sprouts indicate light deprivation and lead to weak, blight-prone plants.
Thermal Advantage: Black buckets absorb solar heat, warming soil faster than the open ground. Ensure 6-8 large drainage holes; saturated soil kills roots via oxygen starvation.
Earthing Up: Continue covering green growth with compost. Potatoes form on underground stolons—the more stem you bury, the higher the yield.
Harmonic Vibration: Lacking glass rigidity, the frame vibrates at specific wind frequencies. This harmonic motion can back out 10mm nuts over time. A spring audit is a safety requirement.
The Boundary Layer: The frame acts as a windbreak. This creates a "boundary layer" of still air inside, which can stay 2°C warmer than the wind-chilled exterior.
Soil Structure: Without a roof, winter rain leaches nutrients. Mulch now with cardboard and compost to suppress weeds and preserve soil biology before planting.
Viability Logic: Parsnips and Onions have a 1-year shelf life. Tomatoes and Brassicas can last 5+ years if stored correctly.
Storage Protocol: Seeds are living embryos in stasis. High humidity triggers them to "wake up," burning their energy reserves and dying. Store in an airtight tin with silica gel at 10-15°C.
