SEED DEPTH
IN PLANTING
Seeds require a specific combination of conditions to start growing and
need to be planted in the soil at a particular depth. For successful
growth, the needs of each type of seed must be met. Most seed packets bear
detailed planting instructions.
Seed Embryo
A seed contains an embryonic plant. Within the hard protective seed coat,
the embryo is usually provided with a small supply of food. The embryo
remains dormant until germination is triggered.
Germination
Seed dormancy is broken when certain conditions are present, including water,
oxygen, temperature, and light or darkness. The depth at which the seed is
planted affects these factors that result in germination, allowing the seed
embryo to grow.
Water and Oxygen
All seeds need to absorb water—usually in the form of dampness rather than
liquid water—to make the seed coat swell and break, help metabolize the stored
food, and thus begin growth. Oxygen is also needed for germination. If a seed
is buried too deeply in the soil, or the soil is waterlogged (which excludes
oxygen), the embryo will not grow and germination will not occur.
Temperature
A seed will germinate only when the soil temperature is right. It will lie dormant
in cold soil, but as spring temperatures rise, frozen water melts, the soil warms
and seed germination occurs. If the seed is planted too close to the surface,
germination may happen too soon and the plant will not survive in air temperatures
that are too cool. If the seed is too deep, it may rot before the temperature rises
enough to cause germination.
Light or Darkness
Most seeds will germinate best in the darkness provided by a covering of soil. Many,
however, require light and need to be planted close enough to the surface so light
can reach them. To stop a seed that needs light from drying out, it can be lightly
covered with a thin layer of horticultural vermiculite, which will retain moisture
but permit the passage of light.
Determining Depth
Seed packets should bear instructions about planting depth. In the absence of this
information, a general rule of thumb is to plant a seed about four times its shortest
dimension, or twice its longest dimension.

WHAT IS THE
EFFECT OF SEED DEPTH
ON PLANT GROWTH?
From seeds the size of dust flakes to huge flower bulbs, plants produce
seeds that populate the world through wind, animal, gravity and water
motion. With millions of seeds expelled each day, only a select few
germinate and grow into successful plants. One major factor determining
plant success is seed depth. If you improperly plant a seed, it has a
higher chance of germination failure.
