Communication & Information
• Inform users/growers of seeds available
• Talk to users about nursery
results/problems
• Survey/gauge demands
Notes for end users of seed:
• Establishment costs are the same for poor
quality seed as for the best material
• Seed is typically less than 5% of the total
establishment cost (for seedling establishment)
• Profitability and success of plantings is highly
dependent on the quality of the seed used
