Maintaining a Healthy, Beautiful Lawn


Crabgrass and Grassy Weeds germinate in the spring when the soil gets warm. Apply ‘Step 1’ during spring months for the best control. Watering lawn after application enhances control and feeding action. After applying, refer to the bag for seeding instructions.

Broadleaf Weed Controls: Apply these products when weeds are actively growing throughout the year. Do not mow 2 days before or after application. Apply to moist grass. Do not water 1-2 days after application, and delay application if rainfall is expected within 24 hours. After applying the broadleaf weed controls, do not seed for 4 weeks.


A total of one inch of water per week, including rainfall, is desirable. Watering deeply two or three times a week in the morning for thirty to forty minutes, if necessary, is most beneficial for your lawn. Avoid frequently watering for short periods of time.


Do NOT mow your grass too short. A height of 2 ½ to 3 ½ inches works best for a healthy lawn. Raise the mowing height during summer months. Keep your mower blade sharp, so that you do not “shred” your grass. Do not mow wet grass. Do NOT cut more than 1/3 of the grass blade. Mow regularly, usually once a week. Clippings may be left on the lawn, provided they do not smother the grass.


Lawns grow best when pH levels are between 6 and 6.7. Take a soil test to determine pH level, or apply 50 pounds of lime per 1,000 square feet per year. You may apply lime at any time of the year and also while applying other lawn products, including our 100% liquid organic fertilizer, our humate, or our crabshell.
