before any planting is done. If water does not drain
out of ho 1 e within 24 hours, conduct soil test.
Plants shall be planted at such a depth that the
crown roots bear the same relative position to finish
grade as they did to the soils where they were grown.
Backfill after planting shall be compacted carefully
into place without inuring the roots of the tree or
breaking up the ball of earth surrounding the roots.
S. Ground Cover:
Ground cover plants shall be planted in staggered rows,
evenly spaced and at intervals called out on the drawings.
Each plant shall be planted with its proportionate amount
of the flat soil in a manner that will insure a minimum
disturbance to the root systems. The cuttings shall be
planted sufficiently deep to cover all roots. Root crown
should bear same relationship to soil as it did in the flat.
lo~diately sprinkle after each planting until entire area
is soaked to a full depth of each hole.

mercial fertilizer at the rate of .5 lbs. (1/2 lb.)
per 1,000 square feet.
(3) Water all planting areas thoroughly to a minimum
depth of 6" for a period of two (2) consecutive
weeks to germinate all residual weed seeds.

Then apply a non-selective broad spectrum systemic
herbicide per manufacturer's directions. No water
shall be applied for a minimum of four (4) days
fol lowing application of contact weed killer.

f4rtilizer, and water in the designated unit proportions.
Fiber 1,800 lbs. per acre
Ecology M -Binder 100 lbs. per acre
Lawn Seed:
lbs. per acre
