> hard work to keep the seedlings alive for long enough to establish and grow.
Yes its hard work & time taking to nurture them. I am from India, we have government funded nurseries here, they are affordable, but they do not provide very good plants. Growing seeds to 2-3 feet plant (which are ready to be planted to the land) takes between 1 to 2 years. If this process can be streamlined with some technology. A lot of effort can be saved.
