Growth—

Kudzu vine can be grown in a wide range of climates from milder areas in the temperate zone to the subtropics and higher elevations in the tropics. It grows best in areas where annual daytime temperatures are within the range 18 - 28°c, but can tolerate 9 - 32°c[2]. When dormant, the plant can survive temperatures down to about -6°c, but young growth can be severely damaged at -1°c[2]. Plants are hardy to about -15°c, they can resprout from the base if they are cut down by frosts[3]. It prefers a mean annual rainfall in the range 1,200 - 1,400mm, but tolerates 950 - 2,200mm[2]. Succeeds in most well-drained soils in a sunny position[3], though it does not make good growth on very light poor sand or on poorly drained heavy clay[4]. Grows best on well-drained loam soil of good fertility[4]. Plants cannot stand waterlogging on any soil[4]. Prefers a pH in the range 5.5 - 6.5, tolerating 5 - 7.1[4, 2]. A deep-rooted pant, once established it is very drought resistant[5, 4]. The tubers can be harvested about 1 year after planting, if grown from cuttings. If left longer in the soil they can become very large, with weights of up to 180 kilos[6]. Pueraria montana has three varieties, all of which can be used more or less interchangeably:- Pueraria montana montana. This form has the smallest flowers. Pueraria montana lobata (Willd.) Maesen & S.M.Almeida ex Sanjappa & Predeep. This is the form most commonly cultivated outside its native range. It has become an extremely invasive weed in southeastern USA, though it has not yet become invasive elsewhere[7]. It is also the form most commonly mentioned for its medicinal and other uses. Pueraria montana thomsonii (Benth.) M.R.Almeida. This form has the largest flowers. The flowers have a sweet vanilla scent[8]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[3].

Propagation

Pre-soak the seed for 12 hours in warm water and sow in a warm greenhouse in early spring. Germination should take place within 2 weeks. Prick out the seedlings into individual pots when they are large enough to handle and plant them out after the last expected frosts[3]. Cover the young plants with a frame or cloche until they are growing away well.
