Tasman sits right alongside Nelson climatically, and gardeners here can generally follow the same frost timing: risk lingers into November most years despite the region's sunny reputation, so tender crops are worth holding back further than the pleasant spring weather might suggest. Lettuce, spinach, silverbeet, peas, beetroot, carrots and dwarf beans aren't frost-sensitive and can go in safely from September regardless.
Tasman's free-draining soils, particularly around Motueka and the Waimea Plains, suit root vegetables especially well once they're in the ground. Carrots and beetroot in particular size up cleanly here without the forking or rot that heavier clay soils elsewhere in the country can cause. That same fast drainage means new plantings dry out quickly through spring, so mulching early and watering consistently matters more than it would in a slower-draining region.
Tomatoes, capsicums, courgette and sweetcorn are worth waiting on until November, and basil and other tender herbs are safer started undercover until then too: a late frost isn't the norm in Tasman, but the region's actual data doesn't support treating it as impossible. Once the season's warmth properly sets in, Tasman's long sunshine hours make up for the wait quickly.
