Two Hour Gardening Project: Stage 15 – Building a Trellis for Climbers

A solid trellis is essential for vigorous climbers like roses and clematis—flimsy ones collapse under weight. We detail wooden trellis construction (plastic mesh alternative). Autumn brings vegetable/fruit harvest.

Needs: trellis materials: 3 pressure-treated softwood posts 2.3 m; nine 1.4 m battens; six 60 cm battens—all 5 cm x 2.5 cm; expanding/rigid softwood trellis, ~15 cm mesh, 3 panels 1.4 m x 1.5 m; 1 pkt 5 cm brass screws; 4.5 L creosote; 12.7 kg cement/sand mix; four 60 cm old pipes; 1 climbing rose; 1 clematis. Time: 8 hours in 2 weeks.

Mid-October Weather/Soil

Autumn to winter transition; equal day/night starts dormancy; day length matters as much as temperature. Bulbs swelling underground for next year.

Flower of the Fortnight: Climbing Roses

Roses are Britain's favorite—outsell other woody plants 10:1. "No roses, no garden." Small gardens: optimize walls with climbers. Flower prolifically on young wood from old framework. Ramblers grow from base yearly. Hundreds of varieties: best climbers 'Handel', 'Golden Showers', 'Parkdirektor Riggers'; ramblers 'Dorothy Perkins', 'Felicite et Perpetue'. Check local center for area-suitable varieties.

Groundwork

Harvest season: pole beans produce till first frost. Pick vegetables at 2/3 catalog size for best flavor. Carrots, radishes, lettuces tastier young. Keep picking beans for continued production. Pickle surplus tomatoes. Salt/freeze surplus beans. Harvest potatoes after haulms die. All vegetable waste to compost—bottom material peaty/odourless. Dig out, use as mulch, turn rest, keep adding. Better: start second bin when first full; alternate years. Learn bug friends/foes from library books.

Project Work: Erecting Trellis, Planting Vines

Trellis is permanent asset—build well, no shortcuts. Dig post holes ≥60 cm deep, 1.4 m apart. Crocks at bottom. Stand unglazed clay land drain pipe upright in each. Creosote buried post section. Hammer thick nails around buried part. Insert posts into pipes. Check vertical (spirit level/plumb line). Wedge with rubble. Nail temporary struts to fence. Pour strong cement/sand mix into pipe and hole. Tamp, top up, tamp, level, slight shoulder as watershed. Cure 1 week. Creosote posts.

Fit horizontal battens (3 per bay, 1.4 m). Countersink into posts if possible. Fix with 5 cm screws. Fix trellis panels to battens with 1.25 cm screws. If plastic-covered wire trellis, use heavy-duty plastic-coated wire. Optional: cap trellis (sheds rain, prolongs life). If on shed, skip posts, start at battens.

Plant: rose at one post, honeysuckle at another, wisteria at third, Clematis montana (or pink form) at fourth—always in well-prepared holes. Keep neat. Only re-creosote when plants dormant—creosote on leaves kills.
