To replace or supply the nitrogen & phosphorus in the same ratio as used by grass & trees. Most lawns, trees, shrubs, bushes & flowers use 3 to 5 parts nitrogen to 1 part phosphorus. All life needs a balanced diet each feeding! Ultimate's 19-4-2 is 4.75 to 1 ratio of Nit/phos plus 16% Sulfur and 12% Iron.
This acid source helps neutralize the alkaline soil to make the natural soil elements more available for plant uptake.
Available iron (ferrous sulfate) eliminates or substantially reduces iron chlorosis (yellowing).
Imbalance (either Alkaline or Acid) ties up many natural soil elements making them unavailable for plant uptake.
From 6.5 to 7.0 (slightly acid).
Guaranteed analysis and the source of nutrients tells the story. Calculate (add) the total usable nutrients in guaranteed analysis X (multiply) the total pounds in the bag = (equals) total usable elements in the bag. Even more important is the combination of elements to match plant need and soil type. "Ultimate" stands out in superior class of its own!
(A) Dimension and Barricade.
(A) Dimension - .107% which is effective on crabgrass 3 to 4 weeks after crabgrass germination so extends application period 3 to 4 weeks in spring.
(B) Barricade - .370% in 20 lb. bag for 5,000 sq. ft. Barricade may have a little longer effective control.
(A) Viper -- a leading broadleaf killer
(A) Pre-emergent herbicides have longer lasting effectiveness (4 to 6 months with Barricade & Dimension). Post-emergent herbicides for broadleaf weeds are contact chemicals with little or no effectiveness on weeds germinating after applied.
(B) Anytime before weeds germinate. Second application may be applied to extend the effective control of hard-to-kill germinating weeds. Pre-emergents have no affect on established broadleaf & grassy weeds.
(A) Only when broadleaf weeds are established.
(B) Only when temperatures are less than 85 degrees F.
(C) Only to wet grass.
(D) Only when no forecast of rain & no watering for 24 to 48 hours following application.
(E) Only when you can avoid contact with garden vegetables, flowers & all desirable broadleaf vegetation.
Step 1 - March ---Apply "Ultimate Crabgrass Preventer w/Dimension" or "Ultimate Crabgrass Preventer w/Barricade".
Step 2 - June---Apply "Ultimate Crabgrass Preventer w/Dimension" or "Ultimate Crabgrass preventer w/Barricade".
Step 3 - Sept.---Apply "Ultimate All Seasons Lawn & Tree Fertilizer".
Step 4 - Nov.---Apply "Ultimate Lawn & Tree Winterizer".
The "Step Ahead Program" is different from traditional recommendations. After started, this program includes (2) applications of crabgrass preventer & (2) applications without herbicides per year. These longer lasting pre-emergent herbicides make this program superior to traditional 4 step programs! - - "Ultimate" is a step ahead!!!
