Planting seeds in
flats, pots, or seed beds, and carefully tending them until they
are ready to be transplanted will improve their survival rate.
However, it also requires a certain amount of time, effort, and
space. Furthermore, seedlings growing in flats need to be
replanted into pots once they have their second set of leaves
before they develop too much root growth.

Planting seeds
directly onto the final planting site requires less time
and effort, and produces satisfactory results in most cases
if a few
guidelines are followed:
- Rake the area free of
large clods of earth and rocks, and compress the soil
slightly.
- Press the seed into the
soil to a depth equal to its diameter, and cover it,
preferably with sifted soil or sand; don't bury the seed
too deeply. Small seed can be raked into the soil surface.
- Cover the soil with a thin
layer of mulch, such as leaves, straw, or composted
sawdust. This will soften the impact of raindrops and
prevent the seeds from being splashed or washed away.
- Don't plant the seeds too
close together. Try to space them so the plants will not
compete with each other for sunlight and water. Be aware
that some seed may be eaten by birds or rodents; you may
find that certain species, such as beaked hazelnut, must
be raised under some sort of protection and planted out as
seedlings to prevent this.
- Keep the seed
bed well-watered, but do not allow the water to puddle. If the planted area will receive occasional
visitors and is near a convenient water source, consider
marking your plot and posting a sign asking visitors to
water it, while avoiding the area as a path or play area.
