Site Condition Recommendations
Site Analysis Cont.
TURF AREA
• 2-3lbs. of Nitrogen per 1000sq/ft.
• 3lbs. Potassium per 1000sq/ft.
• A 5 step weed control and fertilizer program
POOR DRAINAGE & LOW SPOTS
Install extra drains beneath the soil surface where the soil is
too moisture and make proper slope to avoid water gathering in
low spots.
Site Condition Recommendations
Site Analysis Cont.
DEAD PLANT MATERIAL & PLANT OUT OF SHAPE REMOVAL
Removing the dead or damaged plants and replaced with
new material. Some plants lost ornamental function due to their
unpleasant shape.
TRANSPLANT WITHIN THE SITE
Some plants are still in good condition but grow in improper
places or against design purpose. Transplant those to make room
for a turf area, so that kids can spare their time on this site.

INTRODUC NEW PLANTS FOR SEASONAL APPERANCE
Introduce some new species into the site so that every season
here comes out flower of the seasonal.
WIRES REMOVAL & NEGOTIATION WITH NEIBOURS
Residents here install wires between trees or branches as
clothes line. It will girdle the tree to death as the tree grows.
Therefore, we will negotiate with neighbors, convincing them to
give up their clothesline and promising them there will be a better
place for them to dry their clothes.
