- Prefers a sandy loam and a very sunny position [1].
- Réussi dans les sols secs .
- Succeeds in any good garden soil that is not excessively limey [11].
- Most members of this genus become chlorotic when grown on limey soils [200].
- Trees are not very hardy outdoors in Britain, they tolerate occasional temperatures down to between -5 and -10°c, but even in the mildest areas of the country they are likely to be killed in excessively harsh winters [11].
- Ces plantes ont une relation symbiotique avec des bactéries du sol qui forment des nodules sur les racines et fixent l'azote atmosphérique .
- Une partie de cet azote est utilisé par la plante mais une partie est disponible aux autres plantes poussant à proximité [200].
Propagation
- Seed - best sown as soon as it is ripe in a sunny position in a warm greenhouse [1].
- Stored seed should be scarified, pre-soaked for 12 hours in warm water and then sown in a warm greenhouse in March .
- The seed germinates in 3 - 4 weeks at 25°c [133].
- As soon as the seedlings are large enough to handle, prick them out into individual pots and grow them on in a sunny position in the greenhouse for their first winter .
- Plant them out in late spring or early summer, after the last expected frosts, and consider giving them some protection from the cold for their first winter outdoors .
- Cuttings of half-ripe wood with a heel, July/August in individual pots in a frame [78].
- Overwinter in a greenhouse for the first winter and plant out in their permanent positions in late spring or early summer .
- Fair percentage [78].
