We understand you are looking for answers for controlling crabgrass germination without the use of synthetic herbicides or harmful chemicals. Your time will not be wasted with information that are already available elsewhere online. We will dive deep into controlling crabgrass organically and methodically.
PREVENT CRABGRASS SEEDS FROM ROOTING
Your first goal is to control the crabgrass seeds from rooting in the first place. Since we service Austin, Texas, we really can't predict the weather every year. That is just a fact of life in our hometown. We have had very hot and humid winters on and off for the past... who knows how long? Forever? See, crabgrass propagates in hot weather, so a general rule of thumb is to be aware of crabgrass germination whenever the weather is projected to hit above 80F. This can happen at anytime of the year. When it happens, follow our recommendations, and you will be off to a great start.
We recommend using natural corn gluten meal as a go-to organic fertilizer for all types of turf grass. At 9-0-0, it is a good organic fertilizer going into the growing season. This will give your lawn the push it needs to grow. Because natural corn gluten has organic sources of nitrogen, it will not burn the lawn. Nutrients are released as moisture becomes available over a longer period of time. Where natural corn gluten really shines, however, is in its natural herbicidal tendencies. It will not only create a layer to prevent crabgrass seeds from rooting, it will in fact prevent ANY seeds from growing! So do not overseed in Spring if you will be applying corn gluten meal as fertilizer in Spring. Overseed in Fall instead. That's the optimal time to overseed anyways. If you are really concerned about crabgrass, we recommend to use the maximum application recommendation found in the label for best results. This means that a 40 lbs. bag of natural corn gluten meal, if applied at a rate of 20 lbs per 1,000 square feet, will only cover 2,000 square feet. A bag of corn gluten in 2019 will set you back upwards of $45. This is definitely not a cheap alternative to the toxic chemicals available at the local big box store. But this by far is the best pet friendly and child friendly alternative for health conscious people like yourself. Have we mentioned you must water immediately after laying it down? Yes you do have to water right away because birds love eating it. Water also activates the corn gluten meal and breaks it down even further. Corn gluten meal also smells like cereals if you've ever opened a fresh bag. Be aware though that corn gluten meal can rot and decompose if stored improperly. Unless you want your lawn to smell like rotten eggs, we suggest to only use fresh corn gluten meals. A single application will provide up to 4 months of protection from any seeds. Generally, we only recommend using corn gluten meal once a year. You do not need to use it repeatedly if your soil composition is healthy for turf growth. As your lawn becomes thicker and healthier, you can lessen your application volume up to the point where you no longer need it.
CONTROL CRABGRASS SEEDS FROM GERMINATING
If you did not get the chance to read your first goal in time, then this is where you will begin your organic lawn care plan. Your second goal is to control the existing crabgrass. Crabgrass seeds germination can be controlled by mowing high and by bagging all the clippings whenever you mow. No, you will not collect all the seeds with your mower, but you will collect a bunch of them. This will control some of the crabgrass seeds from getting in contact with the soil; thereby, minimizing seed germination. Mowing as high as possible also helps in controlling seeds from germinating. See, taller grass blades lessen lawn heat stress by retaining moisture in the soil. Moisture in the soil means that the soil is cooler than the ambient temperature. Since crabgrass seeds germinate when it's hot, you are lessening germination by keeping the soil cool. Lawns with taller grass blades also provide shade that lessens direct sunlight contact to the crabgrass seeds. This in turn will further lessen seed germination.
