Trees usually produce good seed crops during mast years, which occur every three or more years depending on species. This results in potential supply and demand problems for seed traders particularly for difficult-to-store seeds such as acorns, chestnuts and maples.
Tree seed lots often contain large quantities of empty seeds, which are sometimes difficult to separate out from filled seeds during processing. This means that some seed lots cannot be machine sown into plug trays, which in turn increases labour costs due to thinning and transplanting in nurseries.
Tree seeds are also often dormant when shed and require stratification to promote rapid, uniform germination over a wide temperature range. This requires experience, skill and good time-management as some species have complicated dormancy mechanisms.

This work package is largely funded by CFS.
