The next thing to think about is wire cages to keep the deer off the new plants, and trellises for tomatoes and other climbing things like squash or cucumber. The SFG website and books are geared towards the US market and I haven't yet worked out the equivalent for steel rods etc here in Germany. That sort of material is expensive, from what I've seen in our local DIY shops, but the trellises do need to last and be robust. Copper piping? Would it be strong enough? Keine Ahnung.
