1. Select either a rectangular or
circular planting area.
2. Select the percentage of the
planting area that you'd like
to fill with this plant variety.
3. Enter the amount in inches
that you want to space the
plants. This can vary from a
few inches less than the
plant's width to several
inches more than the plant's
width, depending on your
preference. Plant width is
listed on the product page of
each plant.
4. Enter either the length and
width for a rectangular area,
or the radius of an entire
circular area and the radius
of the internal area which
isn't included in the bed (for
example: the internal area
space could be occupied by
a large tree and therefore
that section won't figure in to
the total area of the bed).
5. Click on "Calculate" to see
the result.
