- Crabgrass needs soil temperatures of 60 degrees to germinate, according to the University of Rhode Island Horticulture Program. Soil temperatures must remain around 60 degrees for a week. If soil temperatures dip or if there is a sudden frost, crabgrass germination will be delayed.

Common St. Augustine Weed Grass Mow St. Augustine to a height of 1 to 2 inches in the spring and 2 to 3 inches in the summer. Crabgrass does not germinate at cool temperatures, and tall grass helps keep the soil cooler in the warm months. Clean your mower after each mowing to get rid of any seeds that could spread the weed grass.

When to Spread Crabgrass Preventer (a Preemergent Herbicide) When to Apply Crabgrass Preventer. Crabgrass seeds germinate in the early Spring when the temperature of the surface soil rises into the 50s and 60s. Once the seeds germinate, the opportunity for prevention is passed. So, applying the preemergent early is key.

- After germination, most seedlings grow best if the air temperature is below 70 degrees F. If temperatures are too warm (over 75), the seedlings will grow too fast and get weak and leggy. Most seedlings grow fine in air temperatures as low as 50 degrees, as long as soil temperature is maintained at about 65 to 70.fter germination, most seedlings grow best if the air temperature is below 70 degrees F. If temperatures are too warm (over 75), the seedlings will grow too fast and get weak and leggy. Most seedlings grow fine in air temperatures as low as 50 degrees, as long as soil temperature is maintained at about 65 to 70.

How Warm Must it Be to Plant Lawn Grass Seed? Usually planted in the early fall, cool-season grass seeds prefer daytime temperatures ranging from 60 to 75 F. With this temperature range, the soil itself is usually between 50 and 65 F -- the right environment for germination.f your seeds remain at their ideal temperature range and are planted no more than 1/4 inch deep, you should see germination after three weeks. It is critical to keep the top 1/2 inch of soil moist with a misty spray so the seeds continue to absorb moisture as the seedling grows larger.

- A: To know when to apply a weed preventer you first have to know when the seeds you are trying to prevent are likely to germinate. Crabgrass seeds need several days of soil temperatures higher than 55 degrees in order to germinate. Most years in Atlanta, March 15 is the date experts recommend you apply the pre-emergent. Only the most shallowly buried crabgrass seeds will be sprouting then but many more will germinate in April and May.

How to Get Rid of Crabgrass in the Lawn Prevention and Maintenance. You can discourage crabgrass by mowing at the proper height for your grass type. Higher mowing, usually at one of the top two setting on your mower, encourages lawn grasses to shade soil which helps prevent the germination of crabgrass seeds. A thick, full lawn seldom contains much crabgrass.

Temperature for planting grass seed Grass seed needs a minimum temperature of 65 degrees and will germinate faster at higher soil temperatures as long as the increased heat doesn't dry out the seeds and soil.emperature. Grass seed germinates when the soil temperature is 65 degrees and above. It's important to understand that it is the soil temperature, and not the surrounding air temperature, that is the trigger for seed germination.

- Grass seed not in good contact with the soil cannot warm up correctly for successful germination. Seeds rely on warmth and soil moisture to swell and sprout. If your seeds remain at their ideal temperature range and are planted no more than 1/4 inch deep, you should see germination after three weeks.arm-season grasses, like St. Augustine (Stenotaphrum secundatum), which grows in U.S. Department of Agriculture plant hardiness zones 8 through 10, rely on daytime temperatures hovering around 80 degrees Fahrenheit for successful germination. But air temperature may not be the best indicator of soil temperature.
