| Propagation |
Seed - it quickly loses viability if it is allowed to dry out. It can be
stored moist and cool overwinter but is best sown as soon as it is ripe
in an outdoor seed bed, though it must be protected from mice, squirrels
etc. Small quantities of seed can be sown in deep pots in a cold frame.
Plants produce a deep taproot and need to be planted out into their
permanent positions as soon as possible, in fact seed sown in situ will
produce the best trees[11]. Trees should not be left in a nursery bed
for more than 2 growing seasons without being moved or they will
transplant very badly. |
