Crabgrass Preventer Fertilizer

  • Fertilizer analysis: 20-0-3&
  • Feeds the lawn for up to 3 full months
  • Kills crabgrass both before and after germination
  • Clear & odorless herbicide that does not stain hands, shoes or walkways
  • Same season-long results as other crabgrass preventers with fewer harmful active ingredients

Jonathan Green’s Crabgrass Preventer plus Green-Up Lawn Fertilizer feeds the lawn for up to three full months and provides pre-emergent control of crabgrass. When applied prior to germination it controls other weeds such as goosegrass, dallisgrass, chickweed, henbit, and oxalis.

This product contains an advanced herbicide known as Dimension® that provides postemergence control, meaning it will kill existing weeds, such as crabgrass, even after they germinate. Postemergence control is limited to crabgrass and is effective for up to four weeks post-germination. It will only kill the plant up to the 3-leaf stage of growth; a fully mature crabgrass plant has 7-leaves.

When to Apply:

  • Apply in the spring prior to germination of crabgrass and other grassy weeds.
  • Best time to apply is from late February through mid-May depending on region.  
  • Spread this product a day or two after mowing and when the lawn is dry. 
  • Do not apply when seeding or under newly laid sod.

Apply:

  • Use a rotary or drop lawn spreader.
  • Check that the spreader opening at the bottom of the hopper is closed.  
  • To select the proper spreader setting see the Spreader Settings section in the accordion below. 
  • Push the lever forward only when ready to spread.
  • Apply fertilizer around the perimeter of the lawn to establish a turning area. Then run the spreader back and forth within the area outlined by your first perimeter application. Always allow an overlap to avoid gaps in coverage. 

Post-Application:

  • Sweep any excess granules off of hard surfaces and back onto the lawn.
  • Thoroughly irrigate the treated area after application for best results. About 1 ½ inches of water per week is sufficient between rainfall and irrigation, but not to the point of run-off. 
  • Once watered, wait a day to mow the lawn allowing the product time to activate.

Winter Survival Fall Lawn Fertilizer

  • Fertilizer analysis: 10-0-20
  • High potassium formula helps promote deep rooting
  • Provides gentle fall feeding and contains nitrogen to help repair summer damage
  • Great for using on newly seeded lawns
  • Encourages winter disease prevention and promotes early spring green-up

Jonathan Green’s Winter Survival Fall Lawn Food is the ideal fall lawn fertilizer to spread anytime from early September through mid-November because air temperatures are cooler and the soil is still warm enough for grass roots to grow deep. Winter Survival provides the nutrients to help boost newly seeded lawns as well as help established lawns grow thicker and greener grass with deeper roots.

This product helps lawns recover from summer stress, feeds grass for up to three months and can be applied to any type of lawn grass. If Winter Survival is spread early in the fall, a second application the first week of November will safeguard the lawn over the winter resulting in greener grass early next spring.

When to Apply:

  • Spread this product a day or two after mowing and when the lawn is dry.
  • Apply the same day as seeding or sodding.
  • Best time to apply is late summer through late fall depending on region.
  • For damaged lawns apply in early fall then again 6 weeks later, for a thicker, greener lawn.  

Apply:  

  • Use a rotary or drop lawn spreader.
  • Check that the spreader opening at the bottom of the hopper is closed.  
  • To select the proper spreader setting see the Spreader Settings section in the accordion below.

Mag-I-Cal® Plus For Lawns

  • Natural soil food for lawns in acidic soil
  • Helps to rapidly raise soil pH increasing nutrient absorption
  • Loosens hard soil promoting air and water penetration for better rooting

Jonathan Green’s Mag-I-Cal® Plus for Lawns in Acidic & Hard Soil contains calcium carbonate in a completely soluble form that is immediately available to adjust soil pH upwards. Poor soil is often the problem in growing a great lawn and calcium is vital to many grass plant functions. When soil is compacted or too acidic, air, water, and nutrients are unable to reach the roots, making it very difficult for grass to flourish.

Lawns thrive in soil with slightly acidic to neutral pH levels ranging from 6.2 to 7.0. When pH levels drop between 4.0 to 6.0 weeds flourish and the grass becomes light green and spindly. Additionally, Mag-I-Cal Plus® helps to break up clay and compacted soils. This improves root penetration and promotes growth by increasing biological activity and releasing nutrients trapped in the soil.

When to Apply:

  • Best applied during the growing season when the soil is not frozen.
  • Safe to apply when seeding or sodding.
  • Spread the product on a dry lawn soon after mowing.

Apply:

  • For best results, rake the lawn vigorously prior to application. 
  • Use a rotary or drop lawn spreader. To select the proper setting see the Spreader Settings section in the accordion below.
  • Apply around the perimeter of the lawn to establish a turning area. Then run the spreader back and forth within the area outlined by your first perimeter application. Always allow an overlap to avoid gaps in coverage.   

Post-Application:

  • To avoid staining, sweep any excess granules off of hard surfaces and back onto the lawn.
  • Irrigate the treated area after application for 15-30 minutes for best results.
  • Once watered, wait a day to mow the lawn to give the product time to activate.
  • For soils with pH lower than 6, repeat applications twice a year. 

Coverage: 

  • 18 lb Bag – 5,000 sq. ft.
