Seed treatment and storagedry 2days; cold stratification in moist perlite, 40degrees F for 4 months
Seedling treatmenttransplant to individual pots when seedlings have 4 true leaves
Softwood cuttingsJuly
Sowing seedseed in trays; 1/8

MineralsN-deficient in very basic soils
Moisture and drainagemoist soils; intolerant to poorly-drained conditions
Salt toleranceintolerant
Growth Pattern
Fruit bearing age / full crop load4y / 8y
Habitat and Climate
ExposurePrefer protected microclimates; Northern exposures protect against early spring frost damage
Frost-free days (FFD)150
Hardiness Zone4
Native Rangenortheast Asia
Rainfall / humidityrequire large volumes of water during entire season; very drought intolerant
Wind / ice / frost susceptibilitysusceptible to early spring and early fall frosts, delays fruiting; Succulent growth very susceptible to hot and cold wind damage
Light recommendationfull sun
