Blade Runners has an organic program for turf to HOA’s

Organic program alternative:
It would be terrific to have a fully organic fertilization and weed control program that was as effective as the traditional approach using synthetic chemical weed control products. Unfortunately there are no proven organic products that kill weeds after they emerge. Corn Gluten can be effective for the pre-emergence control of crabgrass and some broadleaf weeds, please see detailed information below regarding *corn gluten.

*Information regarding Corn Gluten:
Corn gluten is a by-product of wet milling process to make cornstarch. It is an animal feed for cattle, poultry, other livestock, fish and some dog foods. It also contains naturally occurring substances, which inhibit the growth of seed’s tiny feeder roots by causing a break down in the cell wall. The seedlings struggle to get enough moisture, which causes them to die before they ever have a chance to take hold. When used as directed, corn gluten acts as a preemergent natural herbicide that will not harm beneficial insects, soil organisms, pond or stream life. It is also safe around pets and children.
Since corn gluten kills only the roots of sprouting seeds, it can be used around transplants and established vegetables, flowers, fruit, shrubs and lawns. It can be used even up to the day of harvest. Once vegetable or flower seedlings have true leaves, it is then safe to apply corn gluten.
Corn gluten has another benefit. It is 10% nitrogen by weight in a slow release form. As a 10-0-0 fertilizer it can inhibit weed germination and feed your lawn and garden nitrogen. (Additional supplements of phosphorous and potassium may be needed, based on a soil test.)
The only potential hazard that is documented so far is potential allergic reaction from inhalation of dust with certain individuals.
Effectiveness of corn Gluten
• Corn gluten works on seeds not established plants. It will not kill a dandelion plant.
• It has reduced crabgrass by 86% the first year and 98% the second year provided recommended rates are applied in both spring and fall. Dandelion infestations were reduced 100% in plots treated for 4 years in spring and fall.
• Plants tested to date for susceptibility = 23 and include: barnyard grass, smooth crabgrass, curly dock, green & yellow, black nightshade, orchard grass, shattercane, purslane, wooly cupgrass, giant foxtail, lambsquarters, buckhorn, quackgrass, velvetleaf, annual bluegrass, dandelions, creeping bentgrass, black medic, redroot pigweed, catchweed bedstraw, & other common garden weeds.
• Corn gluten lasts 5-6 weeks. There is no carryover. After this time seeds can be planted in treated areas without being effected.
The Green Guardian (https://www.greenerpast.com/tips.html) , offers a liquid application that employs the active ingrediante extract from corngluten along with sugar beet extract that they believe provides post emergent control. I have spoken with some current users who confirm the product is effective. While I cannot offer personal assurance at this time, there is enough evidence to try the program as an organic alternative.

THE PROGRAM
Our organic program is a coordinated effort that employs not only different products, but alternative maintenance practice to bring about desired results while not using conventional control methods. It should be understood that this program will not produce the same results of conventional programs. It is likely that you will have unwanted weed populations in the turf. However, there will be other benefits for the overall health of the turf to include a deeper root system and a greener color.
Change in maintenance and product practice:

Mowing height: The height should be raised an additional inch to 3 ½” in spring and 4” in the summer. This can leave a shaggy appearance from time to time.

Mowing frequency: We would need to mow the property more frequently (an additional 7 mowings per season) to maintain an acceptable appearance and reduce thatch issues.

Increase in aeration: There would be a spring and fall aeration to the property.

Liming: Would become an annual and integrated part of the program.

Seeding: Would become an annual and integrated part of the program.
